关于 Bodhi\r\n\r\n内容产业从来不是一个“大产业”。\r\n\r\n看看《财富》500 强企业中，有多少是内容创作者？只有 4 家。\r\n\r\n这很奇怪。\r\n\r\n人类是精神性生物。我们不只活在物质世界中，还活在彼此创造的精神世界中：故事、音乐、电影、游戏。正是这些创作，陪伴我们度过人生的艰难时刻。\r\n\r\n但内容产业仍有两个关键问题没有解决：**分发** 和 **激励**。\r\n\r\n---\r\n\r\n## 问题所在：激励机制\r\n\r\n激励，意味着当你创造了有价值的内容，你能获得回报，这种回报可能是社交认同（点赞、浏览量），也可以是金钱收入。\r\n\r\n目前有很多变现方式，比如引入广告、卖周边产品。\r\n\r\n但这些方式提高了创作者的门槛——创作者不仅要会创作，还要会做生意。\r\n\r\n那广告和付费墙呢？它们不行吗？\r\n\r\n我们用色情行业来举例，因为这个领域的“价值”比较普遍、也容易衡量。如果连色情都难以赚钱，那说明我们的激励机制有根本性的问题。\r\n\r\n在 Onlyfans 出现之前，Pornhub 上的创作者平均每 1000 次观看仅赚 $0.6。\r\n\r\n为什么这么低？因为广告主不愿意在色情网站投放广告。这揭示了广告机制的一个核心问题——广告商挑选内容和受众。对观众有价值的内容，对广告商未必有价值。\r\n\r\nOnlyfans 采用订阅制，创作者收入明显提高了。\r\n\r\n但 Onlyfans 也并非完美方案，它的问题在于：\r\n\r\n**它降低了内容对世界所创造的整体价值。**\r\n\r\n在 Pornhub 上，你的作品可以被 10 万人观看，虽然收入很低，但其社会价值是实实在在的。\r\n\r\n在 Onlyfans 上，你可能有 100 个订阅者，每人每月付 $9.9，你赚得更多了，但作品只被 100 人看到，整体“蛋糕”变小了。\r\n\r\n**分得更大的蛋糕份额，若蛋糕本身更小，终究不是最优解。我们要做的是把蛋糕做大，并合理分配它。**\r\n\r\n---\r\n\r\n## 更深层的问题\r\n\r\n问题背后其实是一个更深的矛盾：\r\n\r\n信息复制的边际成本为零，但我们的经济系统是为“有成本”的商品设计的。\r\n\r\n卖苹果，你给我一块钱，我给你一个苹果，我们彼此交换了“有限资源”。这是传统经济系统的基础。\r\n\r\n但卖信息（如音乐、文章、视频）时，信息可以无限复制。而你用一个有限的资源（钱）去换一个无限的东西，这就产生了结构性冲突。\r\n\r\n这正是盗版猖獗、创作者回报难、蛋糕缩小等问题的根源。\r\n\r\n---\r\n\r\n## 一条新路\r\n\r\n加密货币的出现，扩展了激励机制的可能性。它允许我们不再只是“买卖”，而去发明一种全新的交易机制，解决传统经济无法解决的激励问题。\r\n\r\n如果我们能在协议层解决这个问题，应用和用户就不必再为“怎么赚钱”而烦恼。\r\n\r\n我们要解决的问题是：**如何激励有价值的内容。**\r\n\r\n这个问题可以分成两个子问题：\r\n\r\n1. 如何识别内容的价值  \r\n2. 如何提供激励\r\n\r\n### 1. 如何识别内容的价值\r\n\r\n内容的价值，不取决于它本身，而取决于它的**受众**。\r\n\r\n同一篇文章，对一个人可能毫无意义，对另一个人可能价值百万；一个教学视频，对某人可有可无，对另一个人可能改变人生。\r\n\r\n这与搜索引擎的逻辑类似——网页的价值不取决于关键词出现多少次，而在于有多少页面引用了它。\r\n\r\n所以我们得出一个关键结论：\r\n\r\n> 协议不需要知道内容本身，它只需要通过用户行为来衡量价值。\r\n\r\n### 2. 如何提供激励\r\n\r\n首先要说明什么**不行**：\r\n\r\n**内容付费墙（paywall）不可行。**\r\n\r\n为什么？\r\n\r\n如果你希望一个激励机制在链上永久运行，那对应的内容也要永久可访问。\r\n\r\n若内容存储在中心化服务器，它可能随时消失或失效，那激励机制也随之崩塌——就像你投资了一家可能瞬间消失的公司，没有意义。\r\n\r\n内容必须存储在如 Arweave 这样的**永久存储链上**。\r\n\r\n但链上的内容是公开的。\r\n\r\n想在公开内容上加付费墙，就必须加密。但加密内容的解密流程呢？如果由中心化服务器解密，一旦服务挂了，内容也无法访问，还是中心化老问题。如果用链上机制解密，那基本上就是公开了。\r\n\r\n所以，**付费墙在技术上不可行，在经济上也低效**。\r\n\r\n进一步说：\r\n\r\n链上的内容具有两个特性：  \r\n- **非排他性**（任何人都能访问）  \r\n- **非竞争性**（你的访问不会影响别人访问）\r\n\r\n这正是**公共物品（Public Goods）**的定义。\r\n\r\n所以，内容激励问题其实就是一个**公共物品资助问题**，而这，是人类千百年来都难以解决的难题。\r\n\r\n---\r\n\r\n## Bodhi 是一次实验\r\n\r\nBodhi 就是为了解决这个问题而设计的实验。\r\n\r\n它不依赖广告，不依赖付费墙，而是把你创作的内容变成一种资产，就像一个迷你公司。\r\n\r\n人们可以直接买卖这份内容的“股份”。\r\n\r\n每次有人购买，价格上升；每次有人出售，价格下降。\r\n\r\n你作为创作者，持有初始股份，并从股价上涨中获益。\r\n\r\n此外，每次有人买卖你的内容资产，你都能获得交易手续费。\r\n\r\n**技术上**，Bodhi 把内容存储在 Arweave 上，并把每个 Arweave ID 映射成一个 ERC1155 资产。用户购买时，该 token 会被铸造，价格基于供给量走一个**二次曲线（quadratic curve）**。\r\n\r\n**金融上**，Bodhi 为长尾内容提供了流动性。即使一个资产只有一个买家，协议作为对手方，也能保证交易的流畅。\r\n\r\n---\r\n\r\n## Bodhi 从哪里来？\r\n\r\n这个想法我思考多年，但让我真正有信心，是一个顿悟：\r\n\r\n> 最难的问题，答案可能不在实体之中，而在“虚空”中 —— 在我们脑海中。\r\n\r\n存在于人类共同想象中的东西，往往才是最有力量的。Bitcoin 的伟大之处正体现在此，尽管这不易被察觉。\r\n\r\n很多人觉得 Meme 和庞氏骗局都是无聊甚至有害的东西。但这两者有一个共通点：**它们都只存在于人类的大脑中，却能极大地激发人的行为动机**。\r\n\r\n我直觉告诉我，Meme 和 Ponzi 被严重低估了，它们或许正是解决公共物品问题的钥匙。\r\n\r\nBodhi 正体现了这种洞见。\r\n\r\n---\r\n\r\n## 未来\r\n\r\n作为实验，就算 Bodhi 没有完全成功，也一定能为后来的协议提供重要启发。\r\n\r\n但如果它成功了，我们将打开一个全新的可能世界。\r\n\r\n因为 Bodhi 协议本身**不收取协议费**，任何人都可以在其之上构建新协议，并设定自己的费用机制。\r\n\r\n例如：\r\n\r\n- 一个基于 Bodhi 的视频平台（类似 Youtube/TikTok）  \r\n- 一个基于 Bodhi 的图书出版协议  \r\n- 一个类似 Steam 的游戏发布协议  \r\n- 一个基于 Bodhi 的去中心化博客/社交平台（类似 Medium/Twitter）  \r\n- 一个社区众筹工具  \r\n- 一个学术论文的发布与资助协议  \r\n- 一个投票协议（也许很好笑，因为贿赂机制是内建的）  \r\n- 一个开放源代码的存储与激励平台（类似 Github）  \r\n...\r\n\r\n现在你对 Bodhi 已有大致了解。\r\n\r\n为了让你更直观地体验它，这篇文章本身就是 Bodhi 上的第一个资产。\r\n\r\n**欢迎尝试交易它。**","creator":"0xBEAFc083600efC2376648bFF353Ce8A3EcaA1463","if_to_text_assets_k_v":true,"likes":0,"tags":{},"author_true":null,"space_contract_addr":null,"share_holders":[]},{"id":1569,"created_at":"2024-12-30T13:15:04.497566+00:00","id_on_chain":15491,"content":"#

Law\"简史\r\n\r\n\r\n[https://x.com/cwweb3/status/1858431255265587237?s=05](https://x.com/cwweb3/status/1858431255265587237?s=05)\r\n\r\n\r\n@王超：1999年11月30日，哈佛法学院教授劳伦斯·莱斯格（Lawrence Lessig）出版了一本新书，其中第一章题为 \"Code is Law\"。这也是“代码即法律”这一概念首次大范围进入公众视野。然而，与如今在加密圈被奉为圭臬的信仰不同，这一理念最初诞生时充满了警示意味。莱斯格试图通过这一论述提醒人们，代码和技术架构本身具有立法般的影响力。换句话说，他呼吁关注技术对自由、隐私和权利可能带来的潜在威胁。然而密码朋克们将这个警告转化为行动，证明了另一种可能：代码不仅可以限制自由，也可以保护自由。\r\n\r\n\r\n在过去十几年间，加密社区用代码创造了新世界。它不完美，但充满活力；它有缺陷，但不断进化；它还很年轻，但已显示出改变世界的潜力。它承载着让世界变得更加开放、透明和公平的承诺，即使这个承诺还未完全实现，但每一个参与者都在用自己的方式，推动这个承诺一步步变成现实。\r\n\r\n\r\n###

1 关于机制\r\n\r\nBodhi 的原型在 2022 年底就已经可以用了，和现在差不太多，但直到 2023 年底才发布。中间并不是有多少开发工作要做，而是在琢磨一些问题，包括这个帖子和回复提到的一些根本性的机制问题。\r\n\r\n机缘巧合下，我获得了很重要的启迪，领悟到了一些东西。我在 PermaDAO 的[公开课](https://www.bilibili.com/video/BV17i421D7D1)和橙皮书的[访谈](https://www.xiaoyuzhoufm.com/episode/669e313616ed944bd7efa132) 中都有谈过这部分。\r\n\r\n结论简单来说，围绕一个公共事物（如内容）建立一种（类 meme 的）纯投机性市场很可能是有效的，并且很可能是唯一的终极的激励手段。你可以为它加版权、加付费墙，这些只是短期有效，最终只会让它更短命。感兴趣的可以听上面那两个链接，里面有详细探讨。总之，Bodhi 是一个今天几乎没有人可以理解，但 20 年后人人都会理解的东西。\r\n\r\n### 2 关于为什么 fee 会给作者\r\n\r\n原因只有一个，就是对作者体验上更简单。\r\n\r\n早期版本中是没有 fee 的，但这会要求创作者必须同时也是一个专业”交易者“，低买高卖，找到合适时机卖出，才能赚到钱。这个不太友好。所以后来就加入了 fee，从刚上线后的反馈来看，还是不错的。最近交易的人很少，这主要也不是 fee 的原因。\r\n\r\n### 3 关于帖子中提到的分享转发功能\r\n\r\n概括来说就是你在构思一种和分发传播相关的经济模型。\r\n\r\n我去年和今年都有琢磨过这个，但一方面没有什么特别牛逼想法，另一方面这个也有点偏离 Bodhi 的职责，Bodhi 是一个存在于底层的协议，分发是上层的工作，即使有人干这事，也应该是应用层的人干。\r\n\r\n不过关于单纯分享到社交媒体这块，确实可以优化一下。\r\n\r\n### 4 Bodhi 不是应用\r\n\r\n关于 Bodhi 最常见的误解就是，“你怎么这个功能都没有，那个功能也没有”，觉得它很单薄。\r\n\r\n然而它原本就不是被设计为给终端用户用的，它是一个底层协议。除了托管和激励内容，它什么也不干。底层做得越少，活得越久。\r\n\r\n官网 [bodhi.wtf](https://bodhi.wtf) 只是一个协议浏览器。所有人们觉得想要的“功能”，大多属于应用层，而我刻意没有做这些事情，即使我非常擅长，我始终希望应用留给大家去做。\r\n\r\n当然今年不得不亲自做一些应用，也是为了让更多人理解和使用 Bodhi。\r\n\r\n###  5 总结\r\n\r\n总之，现在还在很早的阶段，Bodhi 是一个非常特殊的项目，它不仅在技术上处于最前沿，而且在社会科学上也处于最前沿，这是它难以理解的原因。从这个角度来说，它和 Bitcoin 是非常像的。\r\n\r\n正因为它的前沿性，所以其实没有人知道正在发生什么，我自己也不知道。你以为它是一棵半年长大的树，没长大那一定是种子有问题，但有可能它是一棵要 10 年才长大的树。我们无法知道。\r\n\r\n让我们先做个 10

Crypto 更像网络还是计算机？｜预言家周报#270\r\n\r\n![](https://arweave.net/-3Lz1OhLbQImzGR99Wc7fTXxucExilh-RHsD0Bvnq7g)\r\n\r\n先从几天前看到的这篇文章说起，[《a16z 两位创始人：AI 热潮和互联网热潮的区别在哪》](https://mp.weixin.qq.com/s/HECads_DLaKwMQ5QATEJtQ)：\r\n\r\n“从技术本质上来说，Marc Andreessen 认为互联网是一个网络，而 AI 更像是一个计算机。\r\n\r\n互联网本质上是一个连接许多现有计算机并促进新计算机创建的网络，它以网络效应为主导，随着更多人加入，网络的价值随之增加，并促使人们构建了更多新型计算机来连接互联网。\r\n\r\n而 AI，特别是大型语言模型，是一种新型的计算机，一种基于概率的、基于神经网络的计算机，它与以往的冯·诺依曼型计算机（确定性计算机）有很大的不同。\r\n\r\nAI 的发展更类似于微处理器或大型机时代，它处理数据、从中学习并生成输出。它是一个信息处理系统，而不是一个网络。”\r\n\r\n很自然的我就开始想，从技术本质上来说，Crypto 更像网络还是计算机？\r\n\r\n虽然以太坊曾经有一个“世界计算机”的梦想，公链也的确扮演了一种很不一样的计算机的角色，比如相比效率更追求去中心化，这是传统计算机完全没有探索过的一条路线。但是说回来，我还是觉得 Crypto 更像网络，有几点原因：\r\n\r\nCrypto 的核心价值是价值传输网络，为了实现这个核心价值，它需要一套不一样的计算机架构。Crypto 的计算机属性是工具，网络属性才是目的。\r\n\r\nCrypto 的网络效应实在太强了。先发优势和锁定效应都很明显，后来者即使技术领先，要想赶超依然困难。\r\n\r\n换一个角度，有一位互联网前辈跟我说，他认为 Crypto 和互联网一样是偏软件的，而 AI 和智能手机一样是偏硬件的。前者发生革命性变化时，人们往往意识不到，需要一段时间才反应过来，可能是网络足够大才能显示出真正威力。后者就不一样了，硬件有更强的实感，Chatgpt 和 iPhone 一出来就能看出不一样。\r\n\r\n## 值得阅读的文章\r\n\r\n###

是相当早就被提出的 nostr 协议实现可能性了。原理上来说，就是把一个 nostr 客户端跟闪电节点布置在一起，那么通过向那个 nostr 客户端发送消息，就可以控制闪电节点，可以发起支付，也可以生成发票。狭义来说，这解决了一个相当大的问题，就是如果你在自己的家庭网络中部署了一个闪电节点，你人在外面时如何远程控制它的问题。在 nostr 出现以前，可用的方式要么要忍受较长的网络时延，要么必需先获得可被外部访问的 IP 地址。当前，nwc 有两种实现，其中一种可以搭配 LND。不过，如果你懂一些编程，其实你可以自己按照非规范的方式实现跟 nwc 相同的功能。\r\n\r\n广义来说，我一直认为，bitcoin、lightning、nostr，都为个人的网络生存提供了非常重要的工具，有了它们，建立个人主页的必要工具就都有了。nostr

1\r\n\r\n李阳请我写篇文章，聊聊我对这个周期的看法。\r\n\r\n因为我是他所认识的人里，\r\n\r\n为数不多看好这个周期的人。\r\n\r\n这让我觉得很奇怪，有什么理由不看好呢？\r\n\r\n这很像是种了果树，根在长，枝在长，叶在长，只是还没结果实而已。\r\n\r\n如果你只盯着果实，那将会是漫长的痛苦。\r\n\r\n币圈大多是投资者，很容易陷入这种没有果实的悲伤里。\r\n\r\n我觉得大可不必，\r\n\r\n生长是需要时间的，连农民都知道果树不是一天长成的，更何况我们今天种下的是一些从未有过的新物种，更需要我们的耐心和爱。\r\n\r\n### 2\r\n\r\n17/18 年我们经历了一场 ICO 的浪潮，\r\n\r\n诞生了无数的山寨币、空气币、骗局。\r\n\r\n当时许多人认为 crypto 走上了歧路，羞于提起这段历史。\r\n\r\n人们心想，crypto 是一个伟大的、改造社会、拯救人类的东西，居然被用来发行这些没有意义的代币，甚至是骗局，太失望了。\r\n\r\n有些人直到今天也是这么认为的。\r\n\r\n然而站在今天回头看，我们会得出完全不同的结论。\r\n\r\n正是这场投机浪潮带来的大量用户，直接推动了以太坊基础设施的发展，我们获得了更好的钱包、更好的 RPC 节点、更好的开发者工具、更多对于扩容的探索；\r\n\r\n正是这场浪潮中创造的大量长尾资产，它们的交易借贷等金融需求，催生出了我们今天繁荣的 DeFi 生态。\r\n\r\n甚至于我们可以说，17/18 年是以太坊生命历程中，最重要的时期。\r\n\r\n我们应当从中学到，每一个阶段都有它自身的意义，不要着急用当下的眼光去判断它。\r\n\r\n### 3\r\n\r\n前天 Arweave 发布了一个有趣的东西。\r\n\r\n传统的 crypto - AI 交互有点像预言机模式，比如 Autonolas，AI 会在链下进行计算，然后将结果写入区块链。\r\n\r\n而 Arweave 由于它特殊的合约机制，你可以将整个大模型存储在合约内并执行，实现链上原生 AI 与资产的交互。这不仅消除了中心化的风险，还增强了可组合性。\r\n\r\n官方给出的示例很有意思。它们做了一个游戏，游戏里发行了一种“羊驼币”，你可以找到羊驼国王，用你真实的资产（$AR）来换这个羊驼币，但至于他给不给你这个币，完全取决于他的意愿。这个国王就是 AI 控制的。\r\n\r\n完全由 NPC 控制的资产发行，这是过去无法想象的。但显然，它并不仅限于此，未来还有更多可能性。\r\n\r\n![](https://arweave.net/YVqIUC90jYJCU3wlu2JOGIESRcmFNWHH1hupbFpJ2xA)\r\n### 4\r\n\r\n聊这些并不是要聊 Arweave，这不过是我们这个周期许多进展中的一个。\r\n\r\n在游戏上，过去一年我们获得了更多真正可玩的全链游戏，和许多更好的工具；\r\n\r\n在社交上，我们经历了将人代币化的 Friend.Tech，和完全去中心化的社交网络 Farcaster 等一系列项目；\r\n\r\n在内容上，我们看到 Bodhi 试图将一切内容资产化，来构建一个基础 layer；\r\n\r\n在 AI 上，我们获得了 Autonolas 等各种 AI agent，再到 AO 的 AI 模块；\r\n\r\n在 Meme 上，我们见到了大量的新代币，甚至大量的用户自己创建的 Meme coin，以及降低 Meme coin 发行门槛的工具（如 pump.fun）。\r\n\r\n上述这一切，过去一年发生的所有这一切，本质都是相似的。我们可以清晰地看到，crypto 在逐渐延伸到外围其他事物上。这些事物本身也是虚的东西：游戏/人/关系/内容/AI/Meme，只是对于 crypto 该如何与它们交互，人们还在探索中。\r\n\r\n不要问“这有什么意义”，万物的生长都有其意义，当下的我们还无法领悟，但最终我们都会明白。\r\n\r\n不要问“什么时候有 mass adoption”，唯一可以肯定的一件事是，当真的有了 mass adoption，你会怀念那个尚未 mass adoption、万物萌发的时代。\r\n\r\n这就是最好的周期，拥抱这个过程。\r\n\r\n## 值得阅读的文章\r\n\r\n### Cashu：一种以比特币为储备的 ecash

方案（**did:btc**）使用比特币区块链来存储和检索DID信息。链上的UTXO用于控制DID。在交易的见证部分写入数据DID 数据具备更大的扩展性(extensibility)和详细程度(verbosity)，同时减少费用和占用区块空间。\r\n\r\n本规范符合W3C Credentials Community Group当前发布的DID规范[[DID-CORE](https://microstrategy.github.io/did-btc-spec/#bib-did-core)]中指定规范。\r\n\r\n## 本文档状态\r\n本文档是潜在规范的草案。它没有任何标准组织的官方地位或任何种类的代表性，并且不代表任何标准组织的支持或共识。\r\n## 1. 合规性\r\n除了标记为非规范性的部分外，本规范中的所有编写指南、图表、示例和注释都是非规范性的。本规范中的其他所有内容均为规范性的。\r\n\r\n本文档中的关键词MAY（可选）、MUST（必须）和SHOULD（应当）应如[BCP 14](https://datatracker.ietf.org/doc/html/bcp14) [RFC2119](https://microstrategy.github.io/did-btc-spec/#bib-rfc2119) [RFC8174](https://microstrategy.github.io/did-btc-spec/#bib-rfc8174)中所述解释，仅当它们以全部大写字母出现时，如此处所示。\r\n## 2. 引言\r\n该方案的目标是仅使用公共比特币区块链作为数据源，提供无需信任、防篡改且长期有效的去中心化身份，同时确保与[DID-CORE](https://microstrategy.github.io/did-btc-spec/#bib-did-core)规范的完全兼容性，并为未来的扩展提供向前兼容性。\r\n\r\n**did:btc** 利用比特币区块链的固有特性，包括其去中心化架构和不可变账本，以确保身份相关数据的防篡改性以及分布式存储和检索。\r\n### 2.1 背景\r\n#### 2.1.1 比特币\r\n比特币是世界上第一个、最大和最知名的加密货币及区块链。它采用工作量证明机制——通过将交易数据与元数据和随机数混合后进行哈希运算，直到找到一个足够小的哈希值以形成一个“区块”——以确保其账本的顺序和完整性以及其中的交易。全球数千个比特币节点下载、验证并索引创建并在网络中传播的区块。这些节点通常会永久存储区块并与其他节点共享。\r\n\r\n尽管比特币交易通常包含从一个地址到另一个地址的币的移动数据，但它们也可以包含任意数据。一个比特币操作码，OP_RETURN，不仅将一个输出标记为不可花费，而且还允许将最多80字节的任意数据添加到交易中。这一直被用来在区块链上添加短消息、链接和哈希字符串。\r\n#### 2.1.2 铭文\r\n比特币交易主要由两部分数据组成：\r\n1. “输出(Outputs)”，存储比特币的数据结构，包含满足特定花费这些币的条件（例如，指定必须签名花费交易的公钥）。\r\n2. “输入(Inputs)”（又称“前输出”），引用之前的输出并提供满足其花费要求的数据（例如，与指定公钥匹配的签名）。所有输入的值必须大于或等于所有输出的值，从而确保不能“凭空”创建币。\r\n\r\n比特币网络 2017年的协议升级引入隔离见证（SegWit），引入了称为“见证”的第三种数据类型。SegWit交易将所有满足输入的花费条件所需的数据放在见证中，而不是输入中，且这些数据的权重为所有其他交易数据权重的25%，用于计算区块空间消耗和所需费用。这使得与例如OP_RETURN数据相比，见证数据在经济上更具优势，OP_RETURN数据是交易输出的一部分。\r\n\r\n比特币网络2021年的另一次协议升级引入 Taproot（又名SegWit v1），对见证数据的使用方式进行了多项更改。值得注意的是，它取消了对[ScriptPubKey](https://microstrategy.github.io/did-btc-spec/#dfn-scriptpubkey)大小为10,000字节的限制。\r\n\r\n取消这一限制并结合见证数据的压缩，引入了一种称为“铭文”的技术，通过该技术，任意数据被存储在交易的见证数据中。比特币协议故意忽略这些数据，但可以通过包含它们的区块中的铭文感知软件提取和解析这些数据。图像和其他富媒体可以存储在这些任意数据中。\r\n\r\ndid:btc采用了与Ordinals相似（但略有修改）的铭文方法，但仅存储与DID相关的数据和更新。这使得在尺寸和内容方面对DID文档的创建和更新几乎没有限制，同时利用了SegWit压缩。\r\n\r\n### 2.2 与现有DID方法的比较\r\n也有使用比特币区块链的DID方法，但它们引入了额外的外部依赖。本节将这些现有方法与did:btc进行比较。\r\n#### 2.2.1 did:btcr\r\n比特币引用DID方法（did:btcr）在其声明的目的和设计上与did:btc有许多相似之处。然而，它有几个限制，这些限制在did:btc 得以解决。\r\n\r\n首先，did:btcr默认使用secp256k1主题密钥，这些密钥较旧，与比如ed25519这样的新密码学曲线相比，性能和安全性被认为较差。相比之下，did:btc允许使用任何曲线或密钥类型，增强了功能性和向前兼容性。\r\n\r\n其次，did:btcr依赖于引用URL来获取DID文档数据，这破坏了区块链不可变性的本质，因为URL上的内容可能随时间改变或消失。另一方面，did:btc直接在链上存储DID文档的额外元数据，确保了其永久性和完整性。did:btc可以通过铭文在比特币交易的见证中存储任意数量的数据，这一技术得益于taproot脚本路径揭示交易，而taproot在did:btcr于2019年开发时尚不可用。\r\n\r\n最后，did:btc在链上签名比特币交易的“钱包密钥”与可用于认证和作为DID主体进行声明的“主题密钥”之间做了区分。这允许DID的控制者与其主体不同，使第三方可以代表其主体“管理”DID，甚至要求多个签名。事实上，控制DID所需的条件可以像比特币协议控制币一样复杂和安全。因此，更新或撤销DID的必要密钥（例如在主题密钥丢失或被泄露的情况下）可以比主题密钥本身持有更高的安全级别。\r\n#### 2.2.2 did:ion\r\nION（did:ion）也使用比特币区块链用于其去中心化标识符。然而，与did:btc不同，链上的内容仅是指向IPFS中文档的指针，解析ION did需要索引比特币交易所指向的IPFS上的所有数据。虽然这确保了IPFS上DID操作的顺序和完整性，但它引入了比比特币区块链更多的外部依赖。\r\n#### 2.2.3 不基于比特币区块链设施的DID 方案\r\n还有其他使用非比特币区块链的DID方法，本节并未详尽覆盖它们。一般来说，这些方法使用类似的方式与各自的区块链交互，并对其去中心化性质提出类似的声明。然而，比特币是最知名、最成熟、分布最广的区块链。它由最多的工作量证明来保护，且不受任何管理机构的控制。\r\n### 2.3 考虑因素\r\n尽管与使用比特币区块链的先前DID方法相比有所改进，但与使用较不安全的区块链或如互联网域名这样的可信数据源的方法相比，did:btc仍有几个缺点和考虑因素。\r\n\r\n即使有SegWit压缩，进行比特币交易和消耗比特币区块空间也可能是昂贵的。这种DID方法可能是每字节DID文档数据使用成本最高的。尽管这对防止女巫攻击提供了一些好处，通过对创建身份设置成本，但这种成本也由用户承担。\r\n\r\n区块空间的价格也波动很大，经常导致广播交易被包含在区块中前需要等待数小时或数天。did:btc操作永远不会是即时的，可能需要数小时。然而，紧急操作可以通过支付额外费用来加速。\r\n\r\n解析did:btc did需要访问比特币节点。尽管许多区块浏览器和其他公共服务器（如Electrum）免费提供比特币区块链数据的访问，但它们引入了一定程度的信任和外部依赖——这正是did:btc试图消除的。运行自己的比特币节点需要一定程度的计算能力和技术熟练度，并不能期望所有did:btc用户都能做到。然而，专用于did:btc的软件可以设计成以简单、高效的方式运行——仅从比特币区块链索引相关交易并在处理后丢弃其他非必要内容。\r\n## 3. 术语\r\n本节为非规范性。\r\n\r\n本节定义了本规范中使用的术语。每当这些术语在本规范中出现时，都会包含指向这些术语的链接。\r\n### DID索引\r\n在[批量DID创建](https://microstrategy.github.io/did-btc-spec/#batch-create)交易中指定DID的索引。批量创建交易包含一个公钥的字节向量，可以根据密钥长度将其分成数组，DID索引是该数组中公钥的位置。\r\n\r\n例如，一个包含十个32字节ed25519公钥的批次将有一个320字节的向量，其中前32字节代表第一个公钥，接下来的32字节代表第二个公钥，依此类推。\r\n### DID UTXO\r\n用于控制DID的 UTXO(未花费比特币交易输出)。它在与DID本身相同的交易中同时创建，并可用于未来交易中更新或停用DID。DID UTXO是一个支付至Taproot（p2tr）输出，允许为DID定义复杂的花费条件。\r\n### 多键\r\n一种数据模型，结合了指示密钥类型的前缀和公钥字节，并以[MULTIBASE](https://microstrategy.github.io/did-btc-spec/#bib-multibase)格式编码。更多细节见[VC-DATA-INTEGRITY](https://www.w3.org/TR/vc-data-integrity/#multikey)规范。\r\n### TxRef\r\nTxRef 编码提供了一种方便且易于阅读的方法来引用已确认的比特币交易，并可选地引用该交易中的特定输出。did:btc利用TxRef创建了一种标准化、可靠且简洁的方法来引用与DID关联的比特币交易。TxRef在[BIP-136](https://microstrategy.github.io/did-btc-spec/#bib-bip-136)中定义。\r\n### 脚本\r\n用于比特币交易的 [Opcodes](https://en.bitcoin.it/wiki/Script#Opcodes) (操作码) 组成的[脚本语言)(https://en.bitcoin.it/wiki/Script)。\r\n### ScriptPubKey\r\n定义输出花费条件的比特币[脚本](https://microstrategy.github.io/did-btc-spec/#dfn-script)。节点在比特币网络上验证此脚本以确定花费输出的交易是否有效。\r\n## 4. DID 方案规范\r\n### 4.1 名称\r\n将标识此DID方法的名称字符串为：btc。使用此方法的DID必须以以下前缀开头：did:btc。根据DID规范，此字符串必须为小写。\r\n\r\n要引用比特币测试网网络上的交易，DID应使用以下前缀：**did:btc:test**。\r\n### 4.2 特定标识符\r\n方案特定标识符是一个符合[BIP-136](https://microstrategy.github.io/did-btc-spec/#bib-bip-136)的[TxRef](https://microstrategy.github.io/did-btc-spec/#dfn-txref)，它引用了创建DID的比特币交易。\r\n\r\n```\r\n示例1：使用TxRef的示例did:btc标识符\r\ndid:btc:xg4x-ay5y-q5zq-232\r\n```\r\n### 4.3 DID 操作\r\n#### 4.3.1 创建\r\nDID创建交易必须在其第一个输出中包含一个OP_RETURN，按以下顺序包含字节：\r\n\r\n1. 3字节：ASCII 格式的did作为标记交易为DID创建交易的人类可读方式。\r\n2. 1字节：一个包含位(bit-wise)标志的字节，用于指示DID的初始主题密钥(initial subject key)将使用的[验证关系](https://w3c.github.io/did-core/#verification-relationships)。这些位从最低位到最高位依次为：\r\n  1. 认证\r\n  2. 声明\r\n  3. 密钥协商 Key Agreement\r\n  4. 权限调用 Capability Invocation\r\n  5. 权限委托 Capability Delegation\r\n3. 最多76字节：初始主题公钥的[Multikey](https://microstrategy.github.io/did-btc-spec/#dfn-multikey)格式，该格式将原始公钥与一个编解码器前缀结合，根据Multicodec规范指示密钥类型。\r\n\r\n```\r\n[示例2](https://microstrategy.github.io/did-btc-spec/#example-op_return-output-broken-down-by-bytes)：按字节分解的OP_RETURN输出\r\n[BlockStream Testnet Explorer](https://blockstream.info/testnet/tx/5acfba9c13bd92c27e9aa8b8cd75d03730571b2dfcc7f81543e9c15cc1efb961?expand)上可查看的交易\r\n\r\n交易的第一个输出的[ScriptPubKey](https://microstrategy.github.io/did-btc-spec/#dfn-scriptpubkey)为6a2664696403ed01ab96ce260bf08a2fc35eda73fee1357b67e50946ca100af0c452ae695ac73053。\r\n\r\n- 6a：OP_RETURN操作码。\r\n- 26：一个操作码，指示接下来的36字节应该被推送到栈上——这实际上是OP_RETURN有效载荷的长度，不能超过80字节。\r\n- 646964：ASCII中的did\r\n- 03：一个字节，最低两位设置，表示接下来的密钥应该具有DID的认证和声明验证关系。\r\n- ed01：一个Multicodec前缀ed编码为varint，表示接下来将是一个32字节的ed25519公钥。\r\n- ab96ce260bf08a2fc35eda73fee1357b67e50946ca100af0c452ae695ac73053：一个32字节的ed25519公钥。\r\n```\r\n它**可能**包含一个支付至Taproot（p2tr）作为其第二个输出，可用于未来比特币交易中更新或停用DID。这个输出称为DID UTXO。如果交易没有第二个输出，或者第二个输出不是p2tr输出，那么DID是最终的，不能在以后的时间进行更新或停用。\r\n\r\n一旦此交易被确认，其确认的区块高度和交易索引可以编码成TxRef以形成did:btc标识符。DID创建者必须等待交易被确认后至少6个区块再发布其标识符，以减少链重组的风险，以避免 DID的区块高度或交易索引被更改。\r\n```\r\n[示例3](https://microstrategy.github.io/did-btc-spec/#example-txref-encoding)：TxRef编码\r\n上述交易在以下位置被确认：\r\n- 区块高度为2582910。\r\n- 交易索引为132。\r\n- 在测试网网络上。\r\n\r\n这编码成TxRef为xuh5-ayyy-q3q0-kp0，结果产生一个DID标识符为did:btc:test:xuh5-ayyy-q3q0-kp0。\r\n```\r\n##### 4.3.1.1 批量创建\r\n为了减少交易开销和费用成本，DID可以批量创建。由于多个公钥很快就会超过80字节的OP_RETURN限制，因此批量创建交易会将公钥放在揭示交易的见证部分。这需要一个承诺交易(commitment transaction)和一个揭示交易(reveal transaction)，但同时增加了开销。然而，对于批次中的任何数量的DID和密钥，开销是固定的，因此每个创建的DID消耗的虚拟字节成本渐近地接近公钥大小的25%（考虑到隔离见证压缩）。对于ed25519密钥，这个渐近值大约是8字节（32 * 0.25）。\r\n\r\n| 批量大小 | Commitment Txn VBytes | Reveal Txn VBytes | 总VBytes | 每DID VBytes |\r\n| --- | --- | --- | --- | --- |\r\n| 2 | 154 | 148 | 302 | 151 |\r\n| 10 | 154 | 213 | 367 | 36.7 |\r\n| 100 | 154 | 937 | 1091 | 10.91 |\r\n| 1000 | 154 | 8178 | 8332 | 8.33 |\r\n| 10,000 | 154 | 80594 | 80748 | 8.07 |\r\n\r\n每批DID最多与一个[DID UTXO](https://microstrategy.github.io/did-btc-spec/#dfn-didutxo)关联，这对于共享公共控制者的DID集合来说是一个高效的选择。有关此过程的更多细节，请参见[批量更新](https://microstrategy.github.io/did-btc-spec/#batch-update)。\r\n\r\n使用以下步骤批量创建DID：\r\n1. 组装一个在揭示交易中被揭示的有效载荷(payload)。这个有效载荷必须按顺序包含以下字节：\r\n   - ASCII中的did，作为标记交易为DID创建交易的人类可读方式。\r\n   - 一个以varint编码的Multicodec前缀，指示接下来密钥的类型。\r\n   - 一个包含位标志的字节，用于指示将用于以下密钥的验证关系。\r\n   - 一个字节向量，按顺序包含一系列公钥。\r\n2. 创建一个包含以下数据和操作码的铭文[ScriptPubKey](https://microstrategy.github.io/did-btc-spec/#dfn-scriptpubkey)：\r\n   1. 定义揭示交易花费条件的[脚本](https://microstrategy.github.io/did-btc-spec/#dfn-script)。在最简单的情况下，这个脚本会要求一个指定公钥的签名：\r\n      1. 一个32字节的仅x坐标的secp256k1公钥。\r\n      2. OP_CHECKSIG - 表示交易应该有一个与上述公钥匹配的签名。\r\n    2. OP_FALSE后跟OP_IF - 确保遵循比特币协议的节点不进入包含有效载荷的if分支。\r\n    3. 第1步中的有效载荷，以520字节的块分割。\r\n    4. OP_ENDIF\r\n3. 创建一个承诺交易，其单一输出根据[BIP-341](https://microstrategy.github.io/did-btc-spec/#bib-bip-341)为第2步中的[ScriptPubKey](https://microstrategy.github.io/did-btc-spec/#dfn-scriptpubkey)的脚本路径承诺。\r\n4. 创建一个揭示交易，使用其脚本路径花费第3步的输出。这将揭示第1步中的有效载荷，有效地将其写入在确认它的区块中。\r\n5. 为批次中的每个密钥创建[TxRefs](https://microstrategy.github.io/did-btc-spec/#dfn-txref)。这是通过使用已确认交易的区块高度和交易索引以及作为出点的[DID索引](https://microstrategy.github.io/did-btc-spec/#dfn-didindex)来完成的。[DID索引](https://microstrategy.github.io/did-btc-spec/#dfn-didindex)是第1d步中描述的字节向量中公钥的索引。\r\n\r\n| 区块高度 | 交易索引 | DID索引 | TxRef |\r\n| --- | --- | --- | --- |\r\n| 2575424 | 1295 | 0 | xqyx-ay0g-pxhg-hvu |\r\n| 2575424 | 1295 | 1 | 8qyx-ay0g-ppqq-9x6q-s0 |\r\n| 2575424 | 1295 | 2 | 8qyx-ay0g-pzqq-rqps-jw |\r\n\r\n#### 4.3.2 读取（解析）\r\n使用以下步骤可以解析一个did:btc DID：\r\n1. 解码它包含的[TxRef](https://microstrategy.github.io/did-btc-spec/#dfn-txref)，它提供了一个区块高度和交易索引。\r\n2. 获取区块（例如，使用 bitcoin core 节点的getblock调用）并解析它以提取给定索引处的交易。\r\n3. 验证交易是否包含以ASCII中的did开头的OP_RETURN作为其第一个输出。\r\n4. 如果存在，提取OP_RETURN有效载荷的第4字节。读取标记的位（如创建中所指定）以确定DID的验证关系。\r\n5. 如果存在，提取OP_RETURN有效载荷的剩余字节。将此解码为MultiKey以确定主题密钥的密钥类型和公钥。\r\n6. 如果存在，提取第二个输出中DID UTXO的ScriptPubKey中使用的公钥，以确定控制者密钥。\r\n7. 使用上述第3至6步收集的数据构建一个DID文档。\r\n\r\n[示例4](https://microstrategy.github.io/did-btc-spec/#example-a-did-btc-did-document-constructed-from-a-creation-transaction)：从创建交易中构建的did:btc DID文档\r\n```json\r\n{\r\n  \"@context\": [\r\n    \"https://www.w3.org/ns/did/v1\",\r\n    \"https://w3id.org/security/multikey/v1\"\r\n  ],\r\n  \"id\": \"x20r-ayaz-qqtl-ljk\",\r\n  \"controller\": \"did:key:z6DtNrvHVvvKHB7m8LrCmt131TGH7DbzvcPo9mZRoCt5rqms\",\r\n  \"verificationMethod\": [\r\n    {\r\n      \"id\": \"x20r-ayaz-qqtl-ljk#key-0\",\r\n      \"controller\": \"x20r-ayaz-qqtl-ljk\",\r\n      \"type\": \"Multikey\",\r\n      \"publicKeyMultibase\": \"z6MkfNwZ7ncwr54BVWA9taEJLaHAWYEuqMNQfBzrwLEoaoVB\"\r\n    }\r\n  ],\r\n  \"authentication\": [\r\n    \"x20r-ayaz-qqtl-ljk#key-0\"\r\n  ],\r\n  \"assertion\": [\r\n    \"x20r-ayaz-qqtl-ljk#key-0\"\r\n  ]\r\n}\r\n```\r\n上述步骤解析了DID创建时的状态。以下步骤可以确定DID是否已更新，并获取其DID文档的最新版本：\r\n1. 确定最后检查的交易是否有p2tr输出；对于创建交易，这应该在第二个索引中，而对于更新交易，这应该在第一个索引中。如果没有，应将DID视为最终的。如果有，继续步骤2。\r\n2. 检查输出是否已被花费。如果没有，DID尚未更新。如果已被花费，继续步骤3。\r\n3. 获取花费上一步输出的交易。\r\n4. 检查花费交易的见证是否有两个或更多元素，这表明是脚本路径花费。如果没有，这个交易不更新DID，返回步骤1。如果有，继续步骤5。\r\n5. 解析第二个见证元素，它持有锁定脚本，并检查它是否包含一个OP_IF字节后跟ASCII中的did。如果没有，这个交易不更新DID，返回步骤1。如果有，继续步骤6。\r\n6. 解析锁定脚本的其余部分以提取更新的有效载荷。这是通过从第一个OP_IF字节后开始，每520字节读取数据，并在每520字节之前用OP_IF字节分隔，最后以OP_ENDIF结束来完成的。由于比特币协议限制字节向量大小为520字节，因此需要分块。有效载荷中的前三个did字节应该被移除。\r\n7. 有效载荷将是一个描述DID文档更新的JSON文档。这应该被解析并应用于DID文档。有关如何应用这些更新的结构和程序，请参见更新部分。\r\n8. 返回步骤1并重复。\r\n\r\n#### 4.3.3 更新\r\ndid:btc DID可以在链上更新，保留DID标识符，同时修改其对应的密钥和/或DID文档的内容。这是通过创建一个新交易来完成的，该交易花费给定DID的DID UTXO。\r\n\r\n更新是JSON文档，包含4个可能的键：\r\n1. vm：更改验证方法，即用作DID主题的操作密钥。这个键是一个操作数组，可以指定一个索引i、一个Multikey k和/或一个验证关系标志vr。操作分为三个子类型：\r\n  1. 删除，仅提供要移除的密钥的索引。\r\n  2. 更新，指定要更新的密钥的索引以及更新的密钥和/或验证关系。\r\n  3. 追加，指定一个密钥和验证关系，但不指定索引。\r\n2. u：DID文档中密钥的更新。这是一个要在文档中更新的密钥数组。如果一个密钥的值是数组，只有带有提供的id的数组条目会被更新。\r\n3. d：从DID文档中删除的密钥。这是一个要从文档中删除的密钥数组。如果一个密钥的值是数组，只有带有提供的id的数组条目会被删除。\r\n4. a：要追加到DID文档中的密钥。这是一个要添加到文档中的密钥数组。如果一个密钥的值是数组，数组内的条目将被添加到现有数组中。\r\n\r\n下面的JSON文档提供了上述所有类型更新的示例。\r\n\r\n```json\r\n{\r\n  \"vm\": [ // 更改验证方法\r\n    { \"i\": 0 }, // 删除第0个密钥\r\n    { \"i\": 1, \"k\": \"z6Mkk8UN3tPb4sEhEvTGbv5Q6qXsG2hBwsWNjwya4tBBqLur\" }, // 更新第1个密钥\r\n    { \"i\": 3, \"vr\": 7 }, // 更新第3个密钥的验证关系\r\n    { \"k\": \"z6Mkr158mX63UMtTWm42jNbkhExBcVqJWwg5uo9vbyoBHGFk\", \"vr\": 3 } // 追加一个新密钥\r\n  ],\r\n  \"u\": [ // DID文档中密钥的更新\r\n    {\r\n      \"service\": [{\r\n        \"id\": \"linked-domain1\", // 更新id为linked-domain1的服务\r\n        \"serviceEndpoint\": \"https://didservice.com\" // 更新服务端点\r\n      }]\r\n    }\r\n  ],\r\n  \"d\": [ // 从DID文档中删除的密钥\r\n    {\r\n      \"service\": [{\r\n        \"id\": \"linked-domain2\", // 删除id为linked-domain2的服务\r\n      }]\r\n    }\r\n  ],\r\n  \"a\": [ // 要追加到DID文档中的密钥\r\n    {\r\n      \"service\": [{\r\n        \"id\": \"linked-domain3\", // 创建id为linked-domain3的服务\r\n        \"type\": \"LinkedDomains\",\r\n        \"serviceEndpoint\": \"https://bar.example.com\"\r\n      }]\r\n    }\r\n  ]\r\n}\r\n```\r\n这个JSON文档被写入在花费给定DID的DID UTXO的交易的见证中。文档内的更改被应用于相应的DID。\r\n\r\n更新交易可以在交易的第一个输出索引中创建一个新的DID UTXO输出，以允许对DID进行未来的更新。如果没有创建新的DID UTXO输出，DID变为最终版本，不能进一步更新或撤销。\r\n\r\n##### 4.3.3.1 批量更新\r\n对批量创建的DID进行更新是上述结构的JSON数组中的更新。例如，一个旨在更新批次中第5个（基于零）索引的DID的交易将按以下方式结构化：\r\n\r\n```json\r\n[\r\n  {\r\n    \"i\": 5,\r\n    \"p\": {\r\n      ... // 在[更新](#更新)中描述的结构中的更新\r\n    }\r\n  }\r\n]\r\n```\r\n#### 4.3.4 停用（撤销 Revoke）\r\n当其DID UTXO在一个交易中被花费，且第一个输出是一个OP_RETURN，其有效载荷为ASCII中的单字节d时，一个did:btc DID被认为是停用的。这表明DID应该被视为从停用交易的时间起永久停用。\r\n##### 4.3.4.1 批量停用\r\n可以通过揭示一个包含一个对象的JSON文档来停用批量创建的一个或多个DID，该对象在键d下有一个DID索引位置数组。参见下面的示例：\r\n\r\n```json\r\n[\r\n  {\r\n    \"d\": [4, 7, 9] // 停用批次中第4个、第7个和第9个索引的DID\r\n  }\r\n]\r\n```\r\n## 5. 安全考虑\r\ndid:btc继承了比特币本身的安全框架。因此，它对许多常见的互联网攻击具有抵抗力，包括：\r\n- 窃听：比特币交易本质上是公开的，因此窃听不适用。\r\n- 重放：比特币网络上不能进行重放攻击，因为每笔交易永久消耗了它从中花费的UTXO。相同的交易重放将被比特币网络拒绝。\r\n- 消息插入：通常不可能向比特币交易中插入错误数据，因为任何攻击者插入的数据都会导致签名验证失败。一旦交易由其创建者签名并广播，交易的任何第三方篡改都会导致它变得无效。\r\n- 中间人攻击：如上所述，中间人攻击无法在比特币交易上执行，因为比特币交易的任何篡改都会导致它变得无效。\r\n- 删除：比特币交易迅速广播到由数千个节点组成的网络中，删除它们变得不切实际。一旦在区块中确认，删除交易几乎变得不可能，因为这将需要持续的51%攻击。\r\n- 修改：如上所述，修改在签名和/或确认后的交易在比特币上是不可能的。\r\n- 服务拒绝或放大攻击：虽然这些技术上可能在比特币网络上发生，但比特币协议已经采取了许多对策，并且自2009年启动以来几乎实现了100%的正常运行时间。用于did:btc方法的比特币节点面临的DoS威胁或挑战并不超出网络上任何比特币节点已经面临的。\r\n\r\n然而，与密钥管理相关的安全考虑是存在的。攻击者如果窃取了钱包密钥，可以永久控制DID并欺诈性地更新或撤销它们。同样，丢失的钱包密钥会导致永久失去更新或撤销相关DID的能力。\r\n\r\n因此，DID创建者和控制者应该考虑使用钱包最佳实践，如多签名钱包和备份种子短语。\r\n## 6. 隐私考虑\r\ndid:btc继承了比特币本身的隐私框架。区块链是公开的，因此所有交易，包括DID数据和操作，都是公开的。然而，现实世界的身份并未与比特币地址和交易绑定。因此，区块链上的DID可以是匿名的。\r\n\r\n根据DID最佳实践，个人信息应该避免记录在账本上。这不仅是因为区块链的公开性而引起的隐私问题，而且由于任何人都可以写入区块链，这本质上是不可靠的。像任何其他任意数据一样，关于身份的虚假声明或与现实世界身份的连接可能会被记录在区块链上。\r\n### 6.1 监控\r\n与DID创建和更新相关的链上活动是公开的，可能会泄露DID控制者的信息。例如，使用10 BTC输入创建DID的交易表明，DID的创建者至少拥有10 BTC。\r\n### 6.2 关联\r\n区块链的观察者也可能使用区块链分析，将DID交易与其他DID交易或其他金融交易关联起来。例如，具有相同控制密钥的DID或同一批次中的DID可能会被轻易地链接在一起。\r\n\r\n##

My job is to better understand her, so that maybe, someday, more people can understand and help raise her too.\r\n\r\n## Bodhi Will Not Upgrade\r\n\r\nThere was a period I thought Bodhi might need an upgrade, though upgrading always cost a lot.\r\n\r\nTo explore what \"new\" Bodhi should look like, I initiated a novel development approach: developing numerous new protocols on top of Bodhi, assuming that the underlying layer had all the data and interfaces I needed, even if some didn't really exist. This was to figure out what the underlying layer should be like.\r\n\r\nThen, I designed 10 new protocols on Bodhi in one go, each implementing several different contract versions. These new protocols are intriguing, covering various fields and are quite foundational.\r\n\r\nSurprisingly, for most of these protocols, the original Bodhi was sufficient, requiring no new interfaces. For the remaining two or three, with slight adjustments in design, they too worked well on the original Bodhi.\r\n\r\n**Since they all work well, it's highly likely that Bodhi won't need further upgrades**. Let's keep Bodhi simple and stable, and future new features can rely on peripheral or higher-level contracts.\r\n\r\n## Rethinking Upgrades\r\n\r\nThere are no \"mistakes\" in the world. Everything has two sides, a good side and a bad side. No purely bad things.\r\n\r\nWhen we say Bodhi has a \"problem\" that we must fix, we need to think: what is the good side of the problem, and what is the bad side of the potential solution?\r\n\r\nThis is why Bitcoin looks the way it does. We have to understand this deeply.\r\n\r\nBodhi is a protocol that leads the entire industry by at least 2-3 years. Every decision we make today, someone will thank us for it in a year or two.\r\n\r\nWhen we reach a certain point, Bodhi will never die, regardless of the number of its users or how much TVL it has. That's not important at all. We have to understand this.\r\n\r\nNow, let's get to the first App protocol on Bodhi.\r\n\r\n## A Simple Idea\r\n\r\nWhen Bodhi was released in December last year, a lot of people sent messages to me on Twitter, giving feedback, asking questions, or telling me what they built on Bodhi. I'm glad to receive those messages, but using me as a hub is not a very efficient way of communication.\r\n\r\nWe need a place for users and developers to talk, just like [Ethereum Magicians](https://ethereum-magicians.org/) for Ethereum, [Bitcoin Talk](https://bitcointalk.org/) for Bitcoin. We need our own place.\r\n\r\nBefore I put it into practice, one idea suddenly came into my mind: **why not just discuss Bodhi on Bodhi?** Just make a protocol, where all topics and replies are Bodhi assets, then not only do we have a forever live forum, but we also reap the benefits of Bodhi — people can vote with money. I'm happy to vote for good feedback or discussions with my real money.\r\n\r\nThat's where it started.\r\n\r\nBut, again, during development, I suddenly realized: since we already built this group with all features, why not just make it a factory contract (a contract that can create other contracts) like Uniswap or Safe, **then anyone can create his own group with one simple transaction**.\r\n\r\nAnd this protocol, we've named it Bodhi Space.\r\n\r\n## Bodhi Space\r\n\r\nThe whole protocol is written in only 60 lines of code. Any Solidity programmer can audit it in 10 minutes.\r\n\r\nNo protocol fees. No admin. Anyone can create a space, or visit other spaces. Anyone can post content, or buy shares of content to upvote.\r\n\r\nYou can buy not only shares of a post but also shares of a Space. Space holders will split all revenue from contents of that space. This means, every community now has its own DEX, and have all the revenue from that DEX.\r\n\r\nWe offer an easy-to-use interface for Bodhi Space, yet users have the freedom to create their own sites or apps with new features. Bodhi Space is robust; even if the main site goes down, you can still access it through Etherscan or have a programmer set up a basic version quickly. On the protocol level, it's fully permissionless, trustless, and unstoppable.\r\n\r\nPeople may find innovative ways to use it. I'm looking forward to it. This is the beauty of creating something public.\r\n\r\nThis is Bodhi Space. It may look simple, but you are already on the frontier of the entire content industry. I hope you all have fun.\r\n\r\n### Enter Bodhi Space: [bodhi.wtf/space](https://bodhi.wtf/space)\r\n\r\n\r\n<details>\r\n  <summary style=\"margin-top:3rem\"><i>Thanks</i></summary>\r\n\r\nThanks to

Looks like this is slightly better this time. Apologies for the delay there getting started. Okay, so we are super excited today to share AO with you. AO is the actor-oriented hyper-parallel computer that we've been building on top of our weave. We've been actively building this system, pen to paper or fingers to keyboard, for the last approximately year or so. But we've been planning it really since we first started developing SmartWeave four years ago. So it's really the culmination of a lot of work across the whole ecosystem. A lot of the ideas that are presented here are amalgamations of thought from different people. Like, for example, Outprog from EverFinance has been writing about the storage compute paradigm, as has the Warp team, for a long time. And so it's really exciting to see all of this come together. The run order today will be that... First, we will be premiering a launch video, which will take us through how the system works, and show many of the different teams who have been building on top of AO already, and are already part of the ecosystem. And many of those are with us today, so thank you everyone for your help getting this together. And then Tom and I are going to be doing some live coding. We're going to be building a chat room with you all inside AO. And so if you want to take part in that, all you need to do is click on the link in the description. All you need to do is just make sure you have Node and NPM ready to go on your laptops. And at the end of that, we'll be distributing testnet cred, which is the currency of the AO testnet, for everyone to use inside the system while it's booting up towards mainnet. After that, we'll be having a Q&A, and then there will be a community hangout session. There's, I think, 215 people here, so this is a huge crew of Arweavers. Yeah, and this is an open Gather Town space, so you can just walk around and chat to one another. And yeah, it'll be fun and interesting, I think. There are a bunch of different teams here that have already been building on top of AO. So with that, let's get started.\r\n\r\n## Sam\r\nAO is the Hyper Parallel Computer. It's a decentralized computation environment that allows you to run any number of processes, in parallel, at the same time. Previous decentralized compute systems have either enabled large-scale compute or verifiable compute. AO lets you do both at once. Smart contracts are great because they enable you to have verifiable computation without trust. But it isn't actually very much computation. A TI-83 calculator, the kind that you would get in a classroom when you were a kid, does over five times as many instructions per second as the entire Ethereum network, with tens of thousands of computers. And billions of dollars of stake. AO doesn't just let you do more verifiable compute. It lets you do any amount of verifiable compute. This is a bold claim, but we can back it up. First, let's understand how smart contract systems generally work. In Ethereum, everyone on Earth is essentially sharing the same thread of execution. And we're globally locking the memory space when we do so. So when you want to interact with a system, I can't interact with a system. Every person on Earth can interact with a system. Every person on Earth can interact with a system. Every person on Earth can interact with a system. Every person on Earth can interact with a system. Every person on Earth can interact with a system. Every person on Earth can interact with a system. Every person on Earth can interact with a system. Every person on Earth can interact with a system. is essentially interacting one at a time, like a massive global queue. The last generation of blockchains kept the global memory space shared between all users of the system, but they allowed you to lock sub-parts of this, local locking we might call it. This is definitely an improvement, but it's nowhere near sufficient. Essentially, everyone on earth is still queuing to use one computer, and it doesn't matter how much stake and how many resources we bring to the network, that's still just one computer. Some architectures like roll-ups and app chains allow for more threads of execution to be executed at the same time. This is definitely a step in the right direction, but it's only a partial solution. Each of these individual threads is hosting many contracts that are sharing the same memory space. That means that each community or user base is still competing to access one shared resource. AO goes a different route. Internet service is scaled not by making everything happen, but by making everything happen. AO goes a different route. AO does the same thing. Instead of chasing an ever-larger global shared state machine, AO focuses on enabling any number of parallel processes to happen at the same time, and then allowing these processes to coordinate by sending messages between one another just like computers. AO does the same thing. Instead of chasing an ever-larger global shared state machine, AO focuses on enabling any number of parallel processes to happen at the same time, and then allowing these processes to coordinate by sending messages between one another just like computers. AO focuses on enabling any number of parallel processes to happen at the same time, and then allowing these processes to coordinate by sending messages between one another just like computers in data centers and on the internet send packets in order to work together as scale. All of these processes that are running inside AO then roll up onto Arweave's scalable on-chain storage as their permanent host. In fact, none of this would be possible if we hadn't spent six and a half years perfecting the design of an on-chain storage system that scales to arbitrary sizes. That's really the key that enables all of this to occur. So, what's the key that enables all of this to occur? Instead of being a homogenous network, AO is actually constructed of three different sub networks as well as Arweave as its base layer. Let's run through it. When messages first enter AO, the user sends them to a messenger unit, or a MU for short. Users can pay the MU in whatever form that they want, be that tokens, fiat, or even perhaps cows. When it receives a message, the MU is responsible for finding the right scheduler, kind of like a sequencer but a little bit more complex, in the distributed scheduler network. Basically, it allows you to bring your own scheduler. Schedulers can take any form that the user likes. They can be either decentralized, state, or even entirely different blockchains. You could use Bitcoin as an AO scheduler without modifying the core data protocol at all. Schedulers have two simple jobs: give a sequence number to each message, and ensure that it is uploaded to Arweave directly. After the scheduler has assigned our message to a slot and guaranteed its upload, the messaging unit will request that a compute unit, or KU for short, finds out the result of the operation. If the result contains another message, the process is repeated, pushing each new message in parallel around the machine. An AO token staking contract then keeps the behavior of each of these units in check and economically secure. This architecture is relatively simple, actually, but it's unbelievably powerful. And critically, it solves the core problem of blockchain scalability: if you add more units to each of these distributed networks, they gain more power. Each of these sub-networks is a peer-to-peer marketplace where demand for service pushes up the incentive to bring capacity online, and competition pushes down prices for users. Fundamentally, this is a computation system that will never need a fee market. When you use a traditional blockchain like Ethereum, Solana, Bitcoin, you compete with other users to gain access to a limited bandwidth. From a computer to a laptop, from a computer science perspective, what you're essentially doing is queuing up to use the resources of the network. And so, actually, it's not like you're paying a large amount for the compute itself. You're paying a large amount to be the person that can edit state of the system at that point in time. This lets you build smart contracts that run like normal apps: extremely high throughput with great user experience. It also enables developers to build in an unconstrained environment. It lets you build things like large language models, that's AI, running inside smart contracts. You can even build things like decentralized recommendation systems and indexes for social media. This is the type of ability that will allow us to create trustless web services at scale, like actually this time. The testnet of AO launches today, but some people have already been building on it for a few weeks. Let's take a look. AO is so scalable that the sensible way for developers to start interacting with it is to actually to boot up a new process inside. So that's exactly what you do when you're on board with the system. It's like your own personal server inside this new internet. Because my server is separate from your server, we can do any amount of compute on each of them and they operate independently. So one is cool, but like, why not for fun, we'll start up a hundred more. AO is just getting started, but already you will find a new world unfolding inside it. There's tokenized chat rooms where people are discussing what to build on the system. Arenas where dozens of parallel autonomous bots are playing to out-compete each other in virtual worlds. You can even bet on them. Other processes are indexing Arweave and providing provably neutral recommendations for decentralized social media applications. And some people are just trading tokens, what do you know? And now we have 100 new processes inside the computer, all of them permanently stored on Arweave. But here's the kicker. All of these are running in parallel. Yes, each process is like a contract, gives you the same guarantees as a contract. But each can run individually at the speed of a single thread. And if we ever needed more, we could just spin up more. Collectively, these processes can address 400 gigabytes of smart contract RAM, limited only by the WebAssembly virtual machine. Use a different virtual machine, and you can get even more address space. The testnet launches right now. You can check it out at ao.arweave.dev. One of the exciting things about AO is that you can plug any virtual machine into it that you want. EVM, Solana's virtual machine, SVM, WebAssembly, or any other kind of deterministic computation device. This is because at its core, AO is actually an open and flexible data protocol for the storage of computation logs on Arweave's protocol. It is not a permanent ledger, not a network in itself. It gives rise to a network, which gives rise to a staking system on top, in kind of a layered approach. The base layer of AO aims to do for compute what the internet protocols did for data transmission: offer a standardized, open mechanism that suits all types of use cases. Just as you could plug any new type of machine into the internet and exchange packets with other participants, AO lets you plug in any new type of machine and send decentralized messages between them. As well as the core data protocol, node implementations, and testnet, we're also launching a decentralized operating system for AO today. We call it AOS. AOS is simple, powerful, and fun to use. It's genuinely actually fun. It makes working with messages easy and intuitive. You can build with AOS using Lua, the language that millions of devs use to mod Roblox, Minecraft, and also to write core internet infrastructure. If you're a developer, you can learn to use Lua in 15 minutes. It's one of the most simple, intuitive languages on earth. This is why we chose it. While you can program AO using Rust or Solidity if you want to, AOS uses Lua because it gets you thinking at a high level of abstraction. It doesn't bother you thinking about memory or borrow checking. It just gets you thinking about the core computation in your programs. It's simple, elegant, and clear. We gave a demo of AO and AOS to a crew from Arweave India in Bangalore a few weeks ago. Within days, they had already built projects that far exceed the bounds of traditional smart contracting systems. For example, Orbit, an Oracle system for a smart contracting network that allows you to do things you never could in another system. For example, it lets you grab all HTTP webpages and load them into your contract for processing. Not just crypto prices anymore, but real data feeds and access to the open world.\r\n\r\n## Orbit\r\nThat's right, at Orbit, we built an Oracle that can use and store full HTTP requests. It's the bridge between AO and the internet. Accessing that much information would not be possible without using Arweave's scalable storage. Here is how it all works. We have an AO process that fetches JSON data from Arweave. We have an AOS process that fetches JSON data from Arweave. We have an AOS process that fetches JSON data from a URL. The user can send the request to Orbit's AO process with just a single command. Once the module sends back the fetched data, we see the message in our inbox. And when we feed the message ID to any Arweave gateway, we can see the data. \r\n\r\n## Sam\r\nThanks Ayush. One of the most fun parts of working with AOS is its development flow. It lets you prototype, test, and publish right from your console. The best way to show this is just to try it. Perfect. Why don't you walk us through it? \r\n\r\n## Patrick\r\nNow that you know what AO and AOS is, let us begin by diving into the rabbit hole with the Getting Started tutorial. In this tutorial, you'll be met with a couple familiar characters, Morpheus and Trinity. But these aren't just normal characters. They're both your guides in this journey, as well as autonomous AI agents built directly into AO. Now let us begin. The first thing I need to do is open up my terminal. I'm going to maximize this. Okay. I'm going to maximize it, and I'm going to make it nice and big so everybody can see it. I'm going to start my process by typing in AOS. My process has begun. Now let's go ahead and just send a message to the autonomous AI agent, Morpheus. I'm asking Morpheus, are you there? I can receive the message back. Let's see what it says. Morpheus? Are you there? I can receive the message back. Let's see what it says. He says, yes, it's me. I see you finally broken free. But are you really ready to see how far the rabbit hole goes? Your next step you'll find inside of the AO cookbook. This only marks the beginning of the journey that you are going to encounter in the interactive getting started tutorial. Throughout this tutorial, these two autonomous AI agents, Morpheus and Trinity, will continue to pose challenges that will grow your ability. And I'm going to show you how to build your ability and understanding of operating inside of AO. If you want to continue down this journey with me, you can find me inside of the AO cookbook. I look forward to seeing what you learn and what you can build inside of AO.\r\n\r\n## Sam\r\nThanks, Patrick. The AOS console is fun and easy to use, but what if you prefer to use a graphical user interface? Well, the Better Idea crew has you covered.\r\n\r\n## BetterIdea\r\nAnd usability is at the core of a good developer experience, which is why we built Better Idea. Thank you. We built Better Idea. It is an online platform crafted for the AO ecosystem. It's like Collab for Web3 developers, offering familiar intuitiveness while seamlessly integrating with AO's on-chain computational engine that lets you write clean, efficient contracts in Lua. To show you the capability of AO in action, here's a quick demo. This is our notebook interface that executes Lua code on AO. With this, you can easily build and run applications like the one we just showed you. It's easy to use. It's easy to use. This is the one we have here, a chatroom. When we send a message across through a particular process, it updates all of the chatroom member processes to display the message we just sent.\r\n\r\n## Sam\r\nEarlier, I mentioned that AO lets you build new types of smart contracts that wouldn't be feasible on traditional systems. Arweave has already been used to store proofs from other decentralized networks. But AO lets us take this further. The proofs themselves can now be validated natively at any scale on-chain. Take the LightSeed network. It's a decentralized and economically secure bundling system for Arweave\r\n\r\n## LiteSeed\r\nWhich is what we did at LightSeed. We were able to trivially solve otherwise tough problems involving optimistic caching and bundling of transactions in order to offer a faster, cheaper and more reliable way to upload and handle data. In practical use, the data is sent to Bundler with AR. It is then bundled up and uploaded to the network. In this case, we trust the bundler. We use the bundler to refund the excess AR back to us. LightSeed is different. It works by running a network of bundlers on AO, where each bundler is required to stake tokens. When a user makes a request, a bundler is randomly selected, which then uploads the data to Arweave. \r\n\r\n## Sam\r\nThanks, team. At Forward Research, we care deeply about building real protocols. Protocols are exciting because they allow us to offer services that would not be possible otherwise. For example, the Arweave network runs a decentralized storage endowment whose mechanism and risk model is fully transparent. A centralized organization can never be able to offer you the same guarantees because you would always need to trust the execution of its managers over time. Most smart contracting networks attempt to entice developers and users to build on top of them while they are essentially in an incomplete state. This means that users and devs must trust the creators to execute a \"road-blocking\" roadmap to essentially complete the protocol. Where are the guarantees here? With AO, we're trying to do things differently. The mainnet of the protocol we will ship will be full and complete. We anticipate that only Bitcoin-style updates will be required in the future. Minor upgrades with the core features and rights of users remaining unchanged over time. There's no Trust Me Bro roadmap here. Just a full and transparent protocol that you can audit and decide if you want to use yourself. We're also building a coalition of different organizations, each staked into the long term success of the network. There's no core team here per se, just a decentralized ecosystem from day one. In order to support this approach, we are also building a coalition of different organizations, each staked into the long term success of the network. This coalition is open to any and all to join, each gaining an ownership stake in the protocol. We're already starting to build. Tate, why don't you tell us what Community Labs has been creating on AO? \r\n\r\n## Community Labs / Tate\r\nThanks Sam. At Community Labs, we've been building on AO for the past few months and we've been blown away by its power. So much so, that today, we're excited to announce two new protocols: Astro, a new type of stablecoin, and Bark, AO's first exchange. Let's take a look at Astro: Stablecoins are crucial to blockchain adoption because they provide liquidity for users and developers. To bring this to AO, we built Astro. Astro is an over-collateralized stablecoin that is backed by Arweave tokens and lays the foundation for money markets to exist natively within AO. We think that this will be hugely popular among the first trading pairs for AO tokens as well as Arweave token holders. You'll be able to trade Astro and other tokens on Bark, AO's first decentralized exchange. Astro is the beating heart of the new economy on AO. It's structured as an automated market maker, enabling anyone to trade assets quickly and simply. But to do so, exchanges require low latency and high throughput. Of which, AO takes care of both. Pairs live on their own processes, meaning you can have any number of them running in parallel, resulting in settlement speeds far outpacing that of centralized exchanges. The network is a unified messaging format, and anybody building an EVM or Solana's virtual machine on the network can interface with Bark. This level of composability allows developers to comfortably build on Bark in any programming language and even to build autonomous agents on top. Your trades can live on Bark, and so can your bots. Woof. Bark is available starting today on the AO testnet, and Astro will be launching soon. Check it out at bark.arweave.dev and follow us on X at communitylabs.com. \r\n\r\n## Sam\r\nThanks, Tate. One of the most exciting parts of AO is its universal messaging format. It lets anyone plug in new and existing deterministic compute systems, sending messages to any other participants in the ecosystem seamlessly. Think of it like a universal language for blockchains, kind of like a Rosetta Star. This means it can also unify existing smart contract layers, being a universal bridge between all of them, with Arweaver as a backbone. But Marcin, why don't you tell us about how Warp is integrating with AO? \r\n\r\n## Warp\r\nThanks, Sam. Hi, I'm Jacob, founder of Warp Smart Contracts, responsible for the technology. Hi, I'm Marcin, co-founder of Warp. I take care of business development, marketing, and go-to-market. Warp enables Arweave builders to create smart contracts on top of the storage chain. We've been building the platform for over two years, and it's currently used for a wide scope of applications. It's optimized for simple cases, like tokenizing the content in the form of atomic NFTs. On the other hand, it also enables complex projects to act as a base layer for distributed databases. Warp will work within the AO ecosystem as a separate type of process, maintaining all the custom features requested by our users, while benefiting from the scalable AO infrastructure and interconnectivity with other processes. We're excited to join the coalition of Arweave builders, bringing to the table our experience of bootstrapping the smart contract ecosystem, helping to onboard new projects, offering necessary support to developers, and growing the community of users. \r\n\r\n## Sam\r\nThanks. But it doesn't stop there. MEM, another compute network on top of Arweave, is also bringing EVM to AO. Ben, why don't you tell us what you're building? \r\n\r\n## Mem\r\nMEM is a serverless functions platform for Web3 developers to go beyond the limitations of deterministic compute. It can integrate off-chain APIs and traditional web services. MEM is able to send messages that trigger actions inside AO contracts to initiate token transfers, mint assets, and use Arweave's token ecosystem. MEM can act as an open compute oracle for AO, running non-deterministic programs and accessing any data on the internet. This allows AO to break out of the scope of deterministic verified compute and access oracalized data sources, which open up new use cases like reading data from other blockchains into AO. Running traditional Web2 software inside the system. And now, over to Outprog, who will talk about how Evervision and AO work together. \r\n\r\n## EverVision\r\nAO is a decentralized computing environment based on Arweave, supports countless parallel processes, and near unlimited computation power with minimal trust. I proposed the SCP theory in November 2020. Which core idea is off-chain computing and consensus data. With AO's security rooted in decentralized data layer, fostering trustless communication among SCP apps. This global, decentralized computer allows for dynamic allocation of computing resources. Everpay integrating AO transforms into a hot-swap process within the AO network. Often instant, zero-fee blockchain payments through EverID make Web3 easy. This integration extends fast chain capability across the AO network, enhancing application interoperability and enabling seamless EverID usage. AO will also empower Everpay, allowing more SCP application messages to be verified on Everpay, truly achieving the combination of decentralized applications. \r\n\r\n## Sam\r\nSo that's AO. The hyper parallel computer. There's still so much more to say about it, but why don't you just explore it for yourself? Join us on the testnet at ao.arweave.dev. See you there. \r\n\r\n## Chat\r\n\r\n\r\n\r\n\r\n\r\n\r\n\r\nSo now I guess you know what AO is all about. In the next segment, Tom and I are going to take you through building with AO right now. live. As someone mentioned in the chat, you just need Node version 20 and above, and yeah, everything else will just work. So I guess we should just get started. Let's do it. All right, so hopefully you can see my screen now. Excellent. Okay, so I'm just using macOS here, but you could use any operating system. Really, the only dependency to get going with AOS is Node. Really, it doesn't have any other dependencies to speak of. So you can install AOS onto your computer just by running npm i -g and then get AO, and this is actually stored on Arweave, so any gateway will work there. We run this. And Seb, very helpfully, is going to be dropping in the chat in the announcements channel the install instructions, so you can copy and paste the code that you need as you go along. Okay, great. So we have AOS installed locally now. What we can do is we can start a new console inside. This has given me a new process ID. This is going to make things fun, Tom. Okay, let's do it. All right, so this is essentially a computer. As you heard in the video, this is a container. It can have up to four gigabytes of memory. It's more reasonable to think of it like a server running in AWS, but with decentralization properties rather than a traditional smart contract system like Ethereum. We can do basic computation like one plus one. We could also, you know, do a for loop or something like this or something more complex. So I have over here Tom's AOS process ID. Now, AOS, or AO rather, is a message-oriented machine, something that's actually relatively difficult to describe, I think, to newbies, but will be unbelievably powerful long-term, is that AO creates a single system image. So most of our launch announcements today and the communications around it are all focused on the crypto industry, you could say. But really, I would argue that AO is a change. I mean, fundamentally, it's the creation of a decentralized operating system. It creates a single system image that is one version of the world that is spread across an arbitrary number of computers without a leader. And the way that you interact between each of the components inside the system is uniform. This is radically, radically different than anything that's come before, as far as I'm aware. The closest thing is probably a bit, but this doesn't give you smart contract-like verifiability. Yeah, so I think that this is something that people will grapple with long-term. But today, it's just like people understand, okay, it's a scalable smart contracting system. So because it's a message-oriented machine, the most sensible thing that we can do with it when we get started is just send a message. So I'm going to just write \"send.\" And the target is going to be Tom here. And I'm going to say in the data field, \"Hey, Tom.\" And this is actually going to create an Arweave data item. So one of the things that we've improved from SmartWeave to AO is that instead of having data items where you encode an input field, and that's what actually gets passed to your smart contract, instead, what we're doing is we're passing full data items as messages. This means that you can load arbitrary amounts of data inside your smart contracts, your processes inside AO, and also have them tagged, just like you do with Arweave data. And that makes them super, super composable. So yes, here we're just setting the data, but we could also set a tag for it. We could say an action. We could say an action intro, something like this. And so I'm going to press \"send\" here. Okay, I've got a million registered and broadcast requests. Did you, by any chance, send all three of the... Okay, we were only supposed to send one, but that's all right. Okay, so now we have many people registering to use the chat room already. Well, guys, we don't yet have the chat room code loaded, but we're going to do that. We're going to do that in a second. Okay, so now we have many people registering to use the chat room already. Well, guys, we don't yet have the chat room code loaded. Well, guys, we don't yet have the chat room code loaded, but we're going to do that in a second. loaded. We're going to write that in a little while. So you'll need to resend those at that time. But Tom, did you receive my message? Yes, I did. Excellent. So maybe we could show Tom's terminal piece. All right, there we go. So every process has an inbox, and you have handlers. And if it's not handled, it shows in your inbox. So I can look at my inbox, count by just doing pound, inbox, and I can see that I've got four messages. I'm curious to show the last one. So I'll do inbox, pound, inbox. And then I want to see the data. So I'm just going to say data. And it's going to show, hey, Tom, I've got data. And I can also look at the whole inbox message. But I can look at each message. And I can also look at the whole message, but I can look at each property as well. So I can say, here's my tags that I received from the data item. And I can also say who it's from. And cool. I've got a new message. Okay. So let's do negative one. Awesome. There's Sam's address. So I'm just going to save that as a variable. And then I'm going to set up an auto reply. So that when I receive another action of intro, then I'm going to respond automatically. So let's do that with the editor that's built in. Now, this editor is very simple, but it comes in handy in a pinch. So let's fire up the editor. And let's create handles, handler, handlers dot add. Reply. And then I'm going to use a built-in function called handlers dot utils dot has matching tag. And this function, I can say if there's a tag called action and a value called intro, then I can match to that pattern. So any message that comes in, I can create a handler function. So for this function, I'm just going to create a handler that's going to do a send. And that send is going to set the target to message dot from. And the data that's going to be sent is going to be sent to, hi. Okay. And now the last thing I need to do is end the function, close the parentheses, and then just type done in my editor. And that should push my handlers on the list. So let's just check that real quick. And yeah, I've got my reply. So Sam, why don't you send me another message? All right. Let's do it. So I can just go up like a normal terminal, and I can find this thing I sent already. And then I guess I can just send it back. So this message has been added back to my outbox. And you can see here, oh ho ho, I have a new message. But I'm also getting spammed inevitably. We do a live demo. People are going to play with it. This makes sense. All right. You can see here the message from Tom. It says data, hi. Great. So Tom was able to take his server, his process inside AO, and add autonomous code that responded to messages to the edge of the server. And we could also change those over time. One of the fundamental things about using AOS that is different than using a normal smart contracting system is that the code is polymorphic. We can load and change the state just like we would in a programming environment, rather than a more concrete or solid, difficult to use smart contracting system. So we could change this handler we have here not just to say hi, or we could remove it, or we could add new things without redeploying any code. It's all completely flexible, if you want it to be, that is. You can, of course, also set the process to be immutable, just like a normal smart contract. So you get that flexibility. So you can make those systems, what would you say, inflexible. You can make them rigid and give users rights by just making them static at the end when you're done with them. Or you can delegate control of the process to a DAO or a security council, a multisig. It's really up to you. So this is great. How about now we try to create a chat room? These people seem to want to chat, Tom. I get the sense. A lot of people are registering. They are really, really excited to register. All right. Okay. So in order to do that, how about we just open up a new Lua file, and we can do so using VS Code or whatever it is you want. I like to use VS Code with by bindings, but you can really use anything. It doesn't matter. And we can just add two handlers. So basically the idea here is, well, how can we turn our process into a chat room? You really just need to be able to register, and you need to be able to broadcast, right? So you register with the process and say, hey, I would like to hear all of the other things people are saying in the system. And then, yes, you broadcast a message, and it should go to everyone. So to do this is very simple. It's really just building on top of what Tom just showed you. We can create a new handler. We'll give it a name, and this one we'll call register. And we will have a function here. So we take two functions when we make a handler, one that is a matcher and one that is an execution. So when it matches it with the first, it will execute the second. Okay. So we'll take a function. We'll take M, and with our M, we're going to say return M.action, and that's just a tag on top of the Arweave data entry that will relate to the message, is equal to register. Okie-dokie. Sounds good. And then if that does match, we're just going to create a function, which will add the person that sent this message to us. So we'll add the person that sent this message to the list of people that are registered with the server. So to do this, we can just say table.insert, and we'll have a table that we'll make in a second called users, and we will add M, the message, dot from, the person the message, sorry, the, yeah, the person the message is from, or process, rather. Person, process. Person, process. Yes, it can actually both. In AOS, or in AO, really, there's no distinction between processes and end-user wallets. You can send messages to both of them and from both of them. Okay, great. So that will work for registering, and why don't we, while we're here, try to make our code kind of nicer, and we will print when someone sends us this registering user, and we will just say dot dot M dot from, so that we can see what's happening when we run our process. Okay, and then we will make a handler for broadcasting, and this will just look for messages that have an action that is equal to broadcast. Easy enough. And you can make these as complex as you want. We're making them simple here, but this could be a message from someone with an, sorry, a message with an action of broadcast, but it could also be message from a person with a token, message from a person, whatever you want, really. Message with this set of tags attached to it, not just one. It's very, very open and flexible. Okay, so then when we get a message like this, we're going to just go through, well, first we're going to print what that message is, so we'll say, broadcasting message from, and we will just put M dot from in here. Okay, great. And then we can go through each of the users in our, or that have registered with the system, and I heard someone say in the chat, boo, one indexing on tables. Yeah, we also think this is a weird, but it's the way it is. It's like one of the two things that we think is kind of imperfect about Lua. Other than that, it's a very, very simple and clear language. Okay, so for each of the users, we just want to send them a message. So we'll say, AO dot send, and this is a super, super simple interface. You just say, well, what the target is. Okay, we'll go for users sub I, great, and then we will send them an action. It's going to say broadcasted, so they know what type of data they're receiving. And we will say the nickname of the sender is equal to the, the person that sent the message via us. And then we will say that the data is equal to M dot data. So this is the part that we're going to forward. I believe that that is everything that we need to do there. Okay, great. So this is 30 lines of well-spaced code. We'll save that and we go back to our terminal. And now we can just say, hoping I am in the right directory. Yes, I am. Cool. Dot load. In the same way that we had dot editor, there's just this sort of native function to the client, but you can just say dot load and then the file name. So I think we call this one chat.lua. Is there any luck? Yes. Great. And now we can check out the handlers. So we can see here that we have two additional handlers, the register handler and the broadcast handler. And if we wanted to change our code, I don't know, we also add like a broadcaster or something like this, because perhaps you want to differentiate in the future the broadcaster from the nickname. You can just change your code, load it. And this is, this is still a smart contract. What's really happening here is that the smart contract is running the AOS code that that creates this shell that you're using. And that lets us make the inside of that shell, if you will, the functionality on it polymorphic. We can change it over time. And it's very, very simple and flexible to use. Okay. So one thing that this piece of code required is a piece of state, a variable called users. Now, who wants to register? We were going, yeah, Tom, how about you register? How about I register real quick for, and I'm sure others will join in with me. Um, so let's just, uh, do a send from the console and we'll just say target equals Sam. Cause I set Sam up as a variable and action equals register. And, uh, yeah. Um, that's all I need, I think. So let's shoot it in. Okay. And there we go. So I can see now on my terminal that, um, that, uh, yeah. Okay. Not only have I CJ or one CJ. Yeah, there you go. All right. So now we have, gosh, here we go. We have a bunch of users in the system. That's awesome. Cool. Okay. Gosh, even more. So you can see here that we can interact with the state of this AO process live. Like we can, if we wanted to, we're not going to, but we could just run users equals, um, empty table and you would all be unregistered. Um, so this, this is a very, very different programming model for deterministic compute. It's much more sort of liberal and flexible and, uh, lends itself to prototyping. Okay. So this is cool, but like, what if we want to make things more rigid? How about we, we want some smart contract rights? Like what's the point of decentralization in the first place? Well, one way or another, it's all about giving users rights. And if you, as the admin or the person that created the process can just log in and change anything you want, then the users don't really have any rights, right? So there's a variable in, uh, every AOS process called owner. This is the address that is able to log into the process and start playing with the system. Well, we're going to go down now down the path of creating a tokenized chat room and then making it immutable. So I'm going to remove myself as the admin of this system. And in order to do that, there's blueprints in AO that make it extremely simple to create helpful and basic things like tokens. So if I want to, I can just say dot load dash blueprint, blueprint token. Okay, cool. And now if I list my handlers on the, um, on the process, I can see that I've got a bunch more now. Great. And actually if I print balances, I can see that, uh, I now have a balance for my token that is inside my process now. So I did like one line of code. Now I've turned my thing into a process, sorry, into a token. And that's kind of cool. Um, we'll set balances to empty table for now. Now we can go back to our code in, in VS code and we can say, okay, when we match, I actually only want to match when the user, uh, actually has a token in our chat room. So in order to do that, I could just say, um, if M dot from, or rather if users sub M dot from is undefined, I'm ad-libbing here, then, um, we can return skip. No, we want to return, you can return, uh, we'll just return false. Yeah. Okay. Thanks Tom. Um, oh, and we would also want to, uh, we want to check the, the action first. I guess we could do it like this. This is a little bit weird. No, it won't let you register if you, if you have this. And you're in the, um, broadcast. Is that the right one? Yes. Okay. Yeah. Thank you. And, um, okay. Then we'll say not equals undefined and then we'll return true. All right. And then in every other circumstance we will return true. Oh, cool. Seems legit. Excellent. Thanks. All right. So now we're saying, okay. Oh, not users, but balances. Balances dot from, uh, message dot from. So the balance of the person that's sending the message. And if that is not equal to undefined, yeah, that will, you want to ideally say if it's greater than zero. Yes. Um, okay. I think we give it a try. Yep. All right. So now we've just added single line change to our handler here and we can go back to our terminal and we can say, uh, just hot code reload. Basically just load that file again. And now if someone can try broadcasting, please. All right. Thank you. Broadcast is sent. Okay. Let's see what we get. So that shouldn't trigger my handler, which it appears not to. Okay. Looks good. Okay. We got a new message. Was this you, Tom? Ao dot hello world? Nope. That was just someone else. Okay. Yeah. Okay. So your message has, uh, um, has not hit that trigger. So, uh, we can now say, well, what about balances? I'll grab Tom's, uh, Tom's address here from my cheat sheet. And we'll just say Tom's balance is now equal to, uh, one. Oh, whoops. Lol, it was me. Yes. Thank you, X1D. All right. Let's try that again. Um, we'll just do it this way this time. Yeah. Square brackets. Yeah. Okay. Cool. All right. So, you want to try this? All right. Yeah. Let's go ahead and send another message. Hi. Yeah. Aha. Yes. So now Tom has got a token and he's able to broadcast. So we've essentially tokenized this chat room and the state of our chat room is completely manipulable, like in real time, if we want to, which is just, yeah, again, radically different than normal smart contracting. Systems. So we can now modify the state further. Let's say everyone on this user list, let's give them a token so I can open up the editor and I'll say, uh, for I equals one, um, hash users. So for, uh, to the number of users, let's say, um, balances, uh, forgot the do. Oh, no, I did forget the do. So you can do a dot cancel. Yeah. Yeah. Yeah. Thank you. Okay. Cool. Thank you, Tom. Um, balances, sub users, sub I. So we'll get the, each user in turn, and we'll say, you've all got a token. Everyone gets a token. And now, oh, I don't know if N zero I is going to have made it through. Uh, yes, I guess, I guess you probably will have done. Okay. So now if we look at balances, everyone's got a token. Nice. All right. And now feel free to spam each other. There you go. It's already started. Okay. So now my job as a smart contract program here is done. I've prototyped something. I played with it with the community. Everyone engaged with it. Um, we bug fixed things potentially. And at this point we want to make it. Reliable. And so what we do is we can just say, okay, we'll be, ah, we'll do that in just a moment. We want to keep this list. Yeah. We want to keep this list. All right. Well, everyone that, that registered, we promised there would be, um, test net cred for you all. And, uh, we'll see if I think it changed my, um, my idea at the beginning. Um, I think it was good. You think it was good? Okay, good. We will find out. Um, so again, we're just playing with the, uh, with the state of the system life. This will have sent a message to each of the people or rather to the test net cred token distributing to, here we go. I'm getting a bunch of debit notices to each of the people that met registered with this, um, chat room that we found. Um, and then we're just playing with the, uh, with the state of the system live. We've created giving you all 500 test net tokens. So enjoy, you can use them for, uh, things like, yeah, the, uh, arena game in the system. That's you bet a token and build a bot, um, in order to, yeah, in order to basically fight each other and then win each other's tokens, you can build bots that blow each other up. And it's kind of a programming competition. The better you are building a bot, um, which runs autonomously. In AO, the smarter your bot, the more likely you are to blow each other up. The more like you are to win each other's tokens. So have fun with that one. There's also a bunch of other stuff you can do in the test net. We've created a quest board, um, that enables you to, yeah, basically see what's going on in the community and see what you can do in order to, um, test net cred. Um, so you want to, or shall I show the chat? So the dev chat. Be happy to show the dev chat. Thanks, Tom. Well, let's just, um, pull up this, uh, blank process that I've got. Um, let's do the chat demo. And then, uh, to get connected to, to dev chat, all I've got to do is do a blueprint load blueprint and then chat. And that blueprint has connected me to dev chat and I can, uh, list the rooms. And I can, uh, join a room too. So, uh, let's go ahead and join getting started. And as I join a room, I can put a nickname. So, uh, let's go ahead and join getting started. And as I join a room, I can put a nickname. So, uh, let's go ahead and join getting started. And as I join a room, I can put a nickname. So, uh, let's go ahead and join getting started. And as I join a room, I can put a nickname. So, uh, let's go ahead and join getting started. And as I join a room, I can put a nickname. So, uh, let's go ahead and join getting started. And as I join a room, I can put a nickname. So, uh, let's go ahead and join getting started. And as I join a room, I can put a nickname. For the room that I want to be in. And then I can just say, hey. So, hello, AOS. And I can specify my room. But then the last one I specify will be kind of the default. So you don't have to do that. But maybe the first time. So broadcasting to getting started. And, uh, I will replay the last 10 messages. It's like there's lag. But everyone's registering. So there we go. Cool. Awesome. See you on the Dev Chat. Oh, nice. And, um, right. And we can see here the quest board. So how do we interact with the quest board as a user? Yeah. There's a couple ways. Um, the fun way is with Dev Chat. But then you can also just do the send, uh, target. Um, just like we do with any process. But with Dev Chat, we kind of created a little, we made the process a member of the chat. So you can just do say. And then slash quest. And that's going to give you a list of quests. And then there's a quest ID by each one. And when you want to see the details of the quest, you just do say, uh, quest:1. And that will give you a printout of that, that particular quest. Um, and then when you do the quest and you want to, uh, claim the, uh, the quest tokens, you can submit a claim by doing say slash quest. Yeah. I think we're talking to getting started. I'm seeing. And there's a bunch of people here. In the getting started chat. We need to be in the, uh, the quest chat. I think you're absolutely right. Uh, you know what? I'm not in the quest chat, so I've got to join it. So this is a new process. Okay. Join quest and my nickname. Okay. And now let's say quest and quest. There we go. And then I can do colon one. And the quest process is actually chatting back to me, uh, through the dev chat, which is, uh, really cool, I think. Yeah. So, so what's actually happening there, right? Is that there is a, uh, process in the background that has a data protocol that allows you to speak to it and access the quests and things. But Tom has also built a, a router on the front end, which essentially wraps that and makes it available in a text format through the chat interface that is, uh, yeah, native to AO. So it's, there's a bunch of people here in, maybe we could swap back to my screen too, please. Um, there's a bunch of people here. Yeah. Already chatting. So if you're not already in the chat, just remember it's dot load dash blueprint and then chat, and then you'll be in here. Um, and you can, you can chat with us. And this I think is where the community might, might hang out here and on the discord. All right. So, um, quests, uh, fake cat, you have to send the message to the, you have to join and send the message to the quests, um, chat room. You're sending it to the, you're sending it to the getting started one. Okay. So in back in my other process, we said after we were done with the distribution of those, um, of the test net cred, then we would want to make this chat room, uh, static. And we can do this literally just by saying owner equals empty stream. And there we go. So now if I send it one plus one, I try and, you know, say balance is, haha, you all have no more tokens. Doesn't work. I get this eval message because it's going to the default handler. Now there's no handler that wants to listen to the messages from me. And that is an immutable smart contract. But what is really radical and different about AO is that all of these processes that you just spun up that we just interacted with, all of those are running asynchronously completely in parallel. And each can have up to four gigabytes of RAM. They can do arbitrary amounts of compute. You can fit, you know, LLMs even inside them. There's a, I don't have the address for it, so we'll find it later. Or maybe we will post it actually in dev chat later. Um, but there's an arena running inside the system already where bots are fighting against one another. Yeah. You can just go register, um, with your chat client, no less actually. And it will just tell you about what they're doing all day, every day, uh, autonomous agents on chain. Um, and then you can just go and register with your chat client, no less actually. And it will just tell you about what they're doing all day, every day, no less actually. Interacting with one another. And today it's games, but tomorrow it would be markets, right? Like the way that the markets, um, in the traditional finance system work is that 70% of the interactions are actually bots. And we've essentially created a way that those can be brought on chain just to start with as one of the small number of things we can do with this system. All right. So there we go. That's, that's getting on board with AO. Um, now I think there are probably some questions. And so we'll do some Q and A and, and then we'll, yeah, we'll just see you, you're in Dev Chat. So, Seb, what do we got? \r\n\r\nHey, good. Super cool. All right. So we got a couple of questions here. Can you show us how to talk to Morpheus? Um, okay. So in order to talk to Morpheus, well, I think the easiest way to talk to Morpheus is to go to the the, um, go to the cookbook. And to get to the cookbook, you can just go to, uh, ao.arweave.dev or ao.anyarweavegagway and, um, click, I think it says begin, or there's actually two buttons. Try it now. Both will take you to the cookbook and yeah, there's a tutorial there called begin, and it will take you through talking to Morpheus and actually building your own chat room and tokenizing it and a bunch of other fun stuff. And there's also a, um, a tutorial on there if you want to get started building bots that interact with the system that run autonomously inside it. Nice. Siegfried is asking us who's providing the compute, Tom, or how does that work? Neither. Yeah. So, um, AO is a computer composed of three units, a move, a message unit, a coup, a compute unit, and a sue, a schedule unit. And all of those can be run independently and your AOS console can, uh, connect to any of those. And for test net, uh, we set up a little infrastructure, um, but definitely this is open for, for anyone to operate. Yeah, exactly. So there are, there are these three subnets of, of coups, moves, and sues. Um, when you interact with any one message or process, you will use one, uh, of each of those, but there's a, there's networks of each of those components. Um, yeah. So where's the compute come from? Well, it comes from kind of, I guess this decentralized amorphous cloud. Um, yeah, exactly. So the, the code is now live and open on, on GitHub. You can check it out and, um, spin up your own, uh, move coup or sue if you want to, and developers can actually do it. So yeah, this is probably worth going into the, the test net, um, as it's currently formulated uses a proof of authority system. So basically when you start a process, you can decide, um, which moves coups and sues you want to trust, uh, just by the, are we wallet ID? Um, yeah. And, and then you, you basically have delegation of trust. And so at the moment we run a cluster, but anyone else can also run more nodes. And if people trust you, then they can, they can operate on your infrastructure. Um, obviously this is not where we want things to end. This is just the start. The next major component is a proof of stake system that runs on top of this. So basically making it so that you can stake in a contract for the correct execution of either a coup, moo or sue over time. Um, yes. And then you can of course be slashed if you, for example, um, send an incorrect message, or if you refuse to schedule a message on a process, if you're responsible for it, a bunch of those, those interactions, as you would expect. Cool. Thanks. Mr. Kaya is asking, here's a giant broker service, it seems an on-chain HTTP of sorts. So how long does it take for two processes to communicate compared to a standard web communication? Is on-chain verification a thing? Oh, there's lots of interesting questions there. Yeah. Uh, as far as with test net, um, the amount of time it takes to communicate is, is pretty fast and we're constantly optimizing it. But, um, we've pretty much seen, uh, sub-second kind of round trip times, but, uh, we have a, a goal to get to sub 500 milliseconds. Yeah. So, so the, the trade-off you make, I think it's important to be clear about, about trade-offs. Um, this system lets you have a decentralized computer that is composed of any number of computers as part of it running any number of processes in parallel. Um, it literally scales like there is no limit to the, the edge of that system. You can put as many processes as you want inside it, I guess, up to the limit of, are we data transactions, but those are two to the power 256, um, bytes minus one. It's like laughably large. Um, but what you do get is you get some latency when you move between one process and another. And so if you're composing, uh, you know, your interactions across many processes, then you, then you add those together. Um, we think over time people will optimize their setups so that the Kuzmo's and Sue's all speak together, um, extremely efficiently. I would, I would hope long-term we can get it less than about 200 milliseconds, something like this. Um, but yeah, for now it's in about the five, sorry, 800 to 1000 millisecond range, something like this. This is, this is the price you pay for it, but that's actually 800 millisecond, um, confirmation time of normal, uh, yeah, or say blockchain interaction, which is actually relatively fast, uh, for the industry at large. And then you get this wide scaling capability that you don't have otherwise as well. Um, there was another question they had buried in there as well. How does that, how long does it take to process things as well? Well, that was the 800-ish. And on chamber verification, is it, is it in sync or not? Right. Do you want to take this or? Yeah. So, so, um, on-chain verification, um, when, when you sign your data item, uh, it, it is sent to a move and then, uh, the move sends that to a scheduler unit where it bundles it and pushes it onto Arweave. And, and it, it is, um, um, uh, it is a parallel process that happens. It happens very quickly. Um, yeah. Well, I mean, it's, it's, it's this holographic state idea, basically. Yeah. It's, it's that the execution of the code is separated from the consensus about the, sorry, the execution of the message is separated from the consensus about the availability of the message, right? Like Arweave is providing this part where the, the data is persisted and the schedulers are providing the part where the data is made available or, or. Yeah. Enforced publication of the data in the first place. And then the, uh, compute units in a separate process are, are actually computing the state transitions. Yeah. I have a question. This one more regarding, uh, Lua code. Can people bring their own Lua code and just run it in there? Yeah. Yeah, sure. Cool. Yep. Um, the, the, the only caveat is it's pure that, that it is, uh, you know, um, when you execute, it returns a value immediately. Um, when you want to do something that sync, you would send a message and then receive that message. What happens once, um, once we close out the AOS terminal? Like is the process that you persistent? That's a great question. Yeah. Right. Sorry. I forgot to mention that. Um, well, it, nothing basically from the point of view of your process, it doesn't matter whether you're watching or not. It just lives there, uh, indefinitely even. I mean, it's on our weave, so it's permanently available. You could wake that process up in 200 years and poke it and say, please broadcast this message back to all the people that registered during the hello world event. Um, yeah. So, so because the, the compute is not happening in these local terminals, it's, how do you say the, the processes are decentralized. They, they never turn off. They're just silently available, uh, persisted until the last note goes offline, I guess. Yeah. So people are really very excited when main, main net. When main net. Tomorrow. Not tomorrow. Um, yes, we can see your message tanky. Sorry. I'm watching the chat here. There's a bunch of people posting. Um, oh, if you want to send messages directly to our conversation here, you could just send them in the, in the getting started chat. Why not? Yeah. Let's have them in front of us. Um, let me see. So main net, when we expect some time this year, most likely, um, but we want to do the test net properly. Like we really care about it, getting it right. Um, there will have to be significant security audits that the proof of stake system goes through when it's live. Um, there's the, the core data protocol itself is pretty robust at this point. We think, um, the APIs between the different nodes. No types. So compute units, scheduling units, uh, messaging units, they are, um, all relatively robust. I think there's something we might want to do there. Um, switching to push rather than pull, uh, so that we can basically make it a little bit more efficient. But other than that, yeah, it's looking pretty, pretty good. It's just the staking contract is the big part. I'd say. Yep. Nice. Another, another interesting topic that people are asking about. Where's the relationship between our weave and how does that work and how do the tokens relate to each other? Yeah. Okay. So, so two parts, obviously everything on AO is, is stored on our weave. So every interaction generates demand for storing data. Um, and even on our test net, the, an interesting thing about this is that the, the agents being autonomous, so they can wake themselves up and do stuff of their own accord means that they generate money. They generate an unbelievable number of messages, which I think will increase rapidly or radically when, when we have autonomous financial agents in the system, they will want to wake up. And if the price of Bitcoin has changed, they want to adjust their, uh, you know, prices in the, in the downstream markets and so on. So there's obviously that core demand there. Um, but also the, the software of the system will allow you to, uh, endow tokens to our endowment and then mint some part of the token supply inside AO as a result of that. So you can essentially not quite moving the tokens, but you are removing them from one and adding them to the other. So you take one, our weave token on one side, um, you put it in the endowment, which locks it from an arbitrary period of time. You don't lock it with data. You just lock the token. So if anything, it's just increasing the security of the, yeah, we're going to end up with, I think a very, very, very large storage endowment. Um, which is of course removed from the, uh, yeah, removed from the endowment to pay for storage over an extremely long period of time, if it is ever needed, which, you know, you can look at the, the, our wiki for some estimations of like how many of those tokens will actually be needed. Um, there's a bunch of different faces go into it, but then when you do so, you can create the token on the other side as a result of the software. And this will be in a sort of auction process. So if on one day, uh, you know, Tom puts in one token, I put in one token and there's 10 tokens on the other side, then we both get five, for example. Or if you put in two times as many tokens, you put in two tokens step, then you would get 50% of the tokens on the other side. Tell me when I get 25, essentially a daily auction to, to generate these things. Um, yeah, there's, there's some details to be worked out there. That is our current plan and expectation of how the software will work. Um, but that's, that's the broad picture as well as of course, having a part of the token supply for the community that are building this thing. I think it's really important that there is a serious alliance of organizations that have the, you say the firepower to go and make this thing successful and gain adoption. That's I'm sorry. I'm talking a lot, but I think this is an important one. Um, that's one thing I think is, is worth noting. Like everything we've, we've looked at today in, in this, this event has been very, very tech focused and that's because right now, our core focus is getting the best developers. We, um, we know, and that's you guys all here with us in the, in the gather town, um, yeah, on board with the system and starting to build and understand how it works because the developers are going to eventually build the, uh, systems that the end users and consumers make use of. And so, uh, as time progresses in the test net, the focus will, will move from purely dev focused to also obviously covering consumers and end users of the system. Cool. So to that point, Raphael is asking, are there any plans to incentivize a test net? Well, so we have, uh, we, you know, Sam just sent out, um, some tokens called, uh, AO cred and it's a test token and we're doing, um, quest, uh, uh, again, to encourage builders to continue building on this journal journey with us. And those tokens will be just, um, distributed, um, in exchange for, uh, contributions. Yeah, exactly. So there's, there's test net cred, which is the currency of the test net. You could, I mean, the, if you want to play in the arena game, you already need some test net cred is basically a way of doing civil resistance eventually when you have to pay for compute moves and scheduling, um, messaging, computing, scheduling, um, you'll, you'll also pay in the test net, uh, credit, and then afterwards it will live on at least as a commemorative, uh, token. That's awesome. All right. We're coming to the, to the end of this. There's a bunch of other questions, but I think that we will have some time to actually go there and talk to everyone in the community. So, um, perhaps for anyone that didn't catch it, uh, Sam and Tom, what is it called AO? Actor oriented. The fundamental difference with this machine versus other smart contracting systems is it uses the actor oriented power programming paradigm, which is essentially how we've scaled all of, all of the normal distributed systems in the world and all of the web two era as well. It's just like the way you outside of blockchain is the way you do everything actually. And in fact, the internet, right? You guys are all receiving messages right now from our, uh, studio here. Gladly you're receiving messages now. Not like you were earlier. We lost a few messages there, but, but yeah, there's the whole world is glued together by message passing fundamentally. And, uh, AO is. Just a system that brings that into, um, the crypto domain and basically says, let's do decentralized computation where instead of sharing all of the memory, like pretending it's, it's one large and what you would call it, like stick of Ram, basically with a CPU attached, which is obviously not going to scale. That's instead do what does scale, which is just some messages to each other and coordinate that way. So that's why it's called AO. Cool. Well, thank you very much, everyone for, for. Let's meet up down there. Yeah. Yes. We'll see you. We'll see you in the, in the holes. Thanks for being with us, everyone. \r\n\r\n\r\n## 开场\r\n今天我们非常兴奋能与大家分享AO。AO是我们在我们的weave之上构建的「面向执行体」（Actor Oriented）的超并行计算机。我们已经积极地构建这个系统，从笔到纸或者从手指到键盘，大约一年左右的时间。但实际上，自从我们四年前开始开发 SmartWeave 以来，我们就一直在计划它。所以，这真的是整个生态系统中大量工作的高潮。这里呈现的很多想法都是不同人思想的融合。例如， Ever Finance 的 Outprog 一直在写关于存储计算范式的文章，Warp 团队也是，已经很长一段时间了。因此，看到所有这些汇聚在一起真的很激动人心。今天的流程将是...首先，我们将首映一个启动视频，它将带我们了解系统的工作方式，并展示许多已经在 AO 之上构建并且已经是生态系统一部分的不同团队。他们中的许多人今天都在这里，所以感谢大家帮助我们把这一切准备好。然后，汤姆和我将进行一些现场编码。我们将与你们所有人一起在 AO 内构建一个聊天室。所以，如果你想参与其中，你需要做的就是点击描述中的链接。你需要做的就是确保你的笔记本电脑上已经准备好了 Node 和 NPM。在那之后，我们将分发测试网积分，这是 AO 测试网的货币，供大家在系统启动向主网过渡时使用。之后，我们将进行问答环节，然后将有一个社区聚会环节。我认为这里有 215 人，所以这是一个庞大的 Arweavers 团队。是的，这是一个开放的 Gather Town 空间，所以你可以四处走动，互相聊天。是的，我认为这将是有趣和有趣的。这里有很多不同的团队已经在 AO 之上构建。那么，让我们开始吧。\r\n\r\n## Sam\r\nAO 是超并行计算机。它是一个去中心化的计算环境，允许你同时并行运行任意数量的进程。以前的去中心化计算系统要么启用了大规模计算，要么启用了可验证计算。AO 让你同时做到这两点。智能合约很棒，因为它们使你能够在无需信任的情况下进行可验证的计算。但实际上并不是很多计算。一个 TI-83 计算器，就是你小时候在课堂上会得到的那种，每秒的指令数是整个以太坊网络的五倍多，而以太坊网络有成千上万的计算机和数十亿美元的 Stake。AO 不仅让你做更多的可验证计算。它让你做任意量的可验证计算。这是一个大胆的声明，但我们可以证明它。\r\n\r\n首先，让我们了解智能合约系统通常是如何工作的。在以太坊中，地球上的每个人本质上都在共享同一个执行线程。而且我们在这样做时，全球性地锁定了内存空间。所以当你想要与一个系统互动时，我不能与系统互动。地球上的每个人都可以与系统互动。本质上，每个人都在像一个巨大的全球队列一样轮流互动。上一代的区块链保持了全球内存空间在系统所有用户之间的共享，但它们允许你锁定其中的子部分，我们可能称之为局部锁定。这绝对是一个进步，但远远不够。本质上，地球上的每个人仍然在排队使用一台计算机，无论我们为网络带来多少 Stake 和多少资源，那仍然只是一台计算机。一些架构，如roll-ups和应用链，允许同时执行更多的执行线程。这绝对是朝着正确方向迈出的一步，但这只是一个部分解决方案。这些各自的线程中的每一个都托管着许多共享同一内存空间的合约。这意味着每个社区或用户群仍然在竞争访问一个共享资源。\r\n\r\nAO 采取了不同的路线。互联网服务的扩展不是通过让一切发生，而是通过让一切发生。AO 采取了不同的路线。AO 做了同样的事情。AO 不是追求一个越来越大的全球共享状态机，而是专注于使任意数量的并行进程同时发生，然后通过让这些进程彼此发送消息来协调，就像数据中心和互联网上的计算机通过发送数据包来协同工作一样，以实现大规模协作。所有在 AO 内运行的这些进程然后汇总到 Arweave 的可扩展链上存储作为它们的永久主机。事实上，如果我们没有花六年半的时间完善一个可扩展到任意大小的链上存储系统的设计，这一切都是不可能的。这真的是使所有这些发生的关键。所以，是什么使所有这些发生的关键呢？与其是一个同质化的网络，AO 实际上是由三个不同的子网络以及 Arweave 作为其基础层构成的。让我们来过一遍。\r\n\r\n- 当消息首次进入 AO 时，用户将它们发送给一个信使单元（Messenger Unit），或简称为 MU。用户可以用他们想要的任何形式支付 MU，无论是代币、法币，甚至可能是牛。\r\n- 当它接收到一条消息时，MU 负责找到分布式调度器网络中的正确调度器(Scheduler Unit)，或简称为 SU，有点像一个序列器但更复杂一些，基本上它允许你带上你自己的调度器。调度器可以采取用户喜欢的任何形式。它们可以是去中心化的、状态的，甚至是完全不同的区块链。你甚至可以使用比特币作为 AO 调度器，而不需要修改核心数据协议。调度器有两个简单的工作：给每条消息一个序列号，并确保它直接上传到Arweave。\r\n- 在调度器为我们的消息分配了一个槽位并保证了其上传后，信使单元将请求一个计算单元（Compute Unit），或简称为 CU，找出操作的结果。\r\n\r\n如果结果包含另一条消息，这个过程就会重复，将每条新消息并行推送到整个机器中。然后，一个 AO 代币质押合约保持这些单元的行为受到检查并经济上安全。这个架构实际上相对简单，但却不可思议地强大。并且关键地，它解决了区块链可扩展性的核心问题：如果你向这些分布式网络中的每一个添加更多单元，它们就会获得更多的能力。这些子网络中的每一个都是一个对等市场，其中对服务的需求推动了在线带来容量的激励，而竞争则降低了用户的价格。从根本上说，这是一个永远不需要费用市场的计算系统。\r\n\r\n当你使用传统的区块链，如以太坊、Solana、比特币时，你与其他用户竞争以获得有限的带宽。从计算机科学的角度来看，你本质上是在排队使用网络的资源。所以，实际上，你支付的大量费用并不是为了计算本身。你支付大量费用是为了成为那个能够在那个时间点编辑系统状态的人。这让你能够构建像正常应用程序一样运行的智能合约：极高的吞吐量和出色的用户体验。它还使开发者能够在一个无限制的环境中构建。它让你构建像大型语言模型那样的东西，即在智能合约内运行的 AI。你甚至可以构建像去中心化推荐系统和社交媒体的索引这样的东西。这是一种能力，将使我们能够创建可信的大规模网络服务，就像这次一样。\r\n\r\nAO 的测试网今天启动，但一些人已经在上面构建了几周。让我们来看看。AO 是如此可扩展，以至于开发者开始与它互动的明智方式实际上是在其中启动一个新进程。所以这正是你加入系统时所做的。就像你在这个新互联网中拥有自己的个人服务器一样。因为我的服务器与你的服务器是分开的，我们可以在每个服务器上进行任意量的计算，并且它们独立运作。所以一个很酷，但是，为了好玩，我们将启动一百个更多。AO 才刚刚开始，但你已经会在它内部发现一个新世界正在展开。有人们正在讨论在系统上构建什么的代币化聊天室。竞技场里，数十个并行的自治机器人正在虚拟世界中互相竞争。你甚至可以对它们下注。其他进程正在索引 Arweave 并为去中心化社交媒体应用提供可证明的中立推荐。有些人只是在交易代币，你知道的。现在我们在计算机内部有了 100 个新进程，所有这些都永久存储在 Arweave 上。但这里有个关键点。所有这些都在并行运行。是的，每个进程就像一个合约，给你与合约相同的保证。但每个都可以以单个线程的速度独立运行。如果我们需要更多，我们可以随时启动更多。这些进程总共可以访问 400GB 的智能合约 RAM，仅受 WebAssembly 虚拟机的限制。使用不同的虚拟机，你可以获得更多的地址空间。\r\n\r\n测试网现在就启动。你可以在 ao.arweave.dev 上查看。关于 AO 令人兴奋的一点是，你可以将任何你想要的虚拟机插入其中。EVM、Solana 的虚拟机SVM、WebAssembly 或任何其他类型的确定性计算设备。这是因为在其核心，AO 实际上是一个开放和灵活的数据协议，用于在 Arweave 的协议上存储计算日志。它不是一个永久的账本，也不是一个网络本身。它催生了一个网络，这个网络又催生了一个顶层的质押系统，采用一种分层的方法。AO 的基础层旨在为计算做互联网协议为数据传输所做的事情：提供一个标准化的、开放的机制，适用于所有类型的用例。就像你可以将任何新类型的机器插入互联网并与其他参与者交换数据包一样，AO 让你插入任何新类型的机器并在它们之间发送去中心化消息。\r\n\r\n除了核心数据协议、节点实现和测试网外，我们今天还为 AO 推出了一个去中心化操作系统。我们称之为 AOS。AOS 简单、强大且易于使用。它真的很有趣。它使得处理消息变得简单直观。你可以使用 Lua 构建 AOS，这是数百万开发者用来修改 Roblox、Minecraft 以及编写核心互联网基础设施的语言。如果你是开发者，你可以在 15 分钟内学会使用 Lua。它是地球上最简单、最直观的语言之一。这就是我们选择它的原因。虽然如果你愿意，你可以使用 Rust 或 Solidity 来编程 AO，但 AOS 使用 Lua 是因为它让你在高层次的抽象上思考。它不会让你考虑内存或借用检查。它只让你考虑程序中的核心计算。它简单、优雅、清晰。几周前，我们向 Arweave India 在班加罗尔的团队展示了 AO 和 AOS。几天内，他们已经构建了超出传统智能合约系统范围的项目。例如，Orbit，一个为智能合约网络设计的 Oracle 系统，它让你做以前在其他系统中做不到的事情。例如，它让你抓取所有 HTTP 网页并将它们加载到你的合约中进行处理。不再只是加密价格，而是真正的数据源和开放世界的访问。\r\n\r\n## Orbit\r\n没错，在 Orbit，我们构建了一个可以使用和存储完整 HTTP 请求的 Oracle。它是 AO 和互联网之间的桥梁。没有使用 Arweave 的可扩展存储，访问这么多信息是不可能的。这里是它的工作原理。我们有一个从 Arweave 获取 JSON 数据的 AO 过程。我们有一个从 URL 获取 JSON 数据的 AOS 过程。用户可以通过一个简单的命令向 Orbit 的 AO 过程发送请求。一旦模块发送回获取的数据，我们就会在收件箱中看到消息。当我们将消息 ID 提供给任何 Arweave 网关时，我们可以看到数据。\r\n\r\n## Sam\r\n谢谢 Ayush。与 AOS 一起工作最有趣的部分之一是它的开发流程。它让你可以直接从控制台原型设计、测试和发布。展示这一点的最好方式就是尝试一下。完美。你能带我们走一遍吗？\r\n\r\n## Patrick\r\n现在你知道了什么是 AO 和 AOS，让我们开始深入「入门教程」的兔子洞。在这个教程中，你会遇到几个熟悉的角色，Morpheus 和 Trinity。但这些不仅仅是普通角色。它们既是你在这次旅程中的向导，也是直接构建在 AO 中的自治 AI 代理。现在让我们开始。我需要做的第一件事是打开我的终端。我要最大化这个。好的。我要最大化它，并且我要让它足够大，这样每个人都可以看到。我将通过输入 AOS 来开始我的过程。我的过程已经开始。现在让我们继续，向自治 AI 代理 Morpheus 发送一条消息。我在问 Morpheus，你在那里吗？我可以收到回信。让我们看看它说什么。Morpheus？你在那里吗？我可以收到回信。让我们看看它说什么。他说，是的，是我。我看到你终于挣脱了束缚。但你真的准备好了解兔子洞有多深吗？你的下一步将在 AO 食谱中找到。这只标志着你将在互动入门教程中遇到的旅程的开始。在整个教程中，这两个自治 AI 代理，Morpheus 和 Trinity，将继续提出挑战，以增强你的能力。我将向你展示如何在 AO 内部构建你的能力和理解。如果你想和我一起继续这段旅程，你可以在 AO 食谱中找到我。我期待看到你学到了什么以及你能在 AO 中构建什么。\r\n\r\n## Sam\r\n谢谢，帕特里克。AOS 控制台既有趣又易于使用，但如果你更喜欢使用图形用户界面怎么办？好吧，Better Idea 团队为你提供了解决方案。\r\n\r\n## BetterIdea\r\n可用性是良好开发者体验的核心，这就是为什么我们构建了 Better Idea。谢谢。我们构建了 Better Idea。这是一个为 AO 生态系统量身定制的在线平台。它就像 Web3 开发者的 Collab，提供熟悉的直观性，同时无缝集成 AO 的链上计算引擎，让你能够用 Lua 编写干净、高效的合约。为了向你展示 AO 的能力，这里有一个快速演示。这是我们的笔记本界面，它在 AO 上执行 Lua 代码。有了这个，你可以轻松构建和运行应用程序，就像我们刚才展示的那样。它易于使用。它易于使用。这就是我们这里拥有的，一个聊天室。当我们通过特定过程发送一条消息时，它会更新所有聊天室成员的过程以显示我们刚刚发送的消息。\r\n\r\n## Sam\r\n之前，我提到 AO 让你能够构建在传统系统上不可行的新类型智能合约。Arweave 已经被用来存储来自其他去中心化网络的证明。但 AO 让我们能够更进一步。现在，证明本身可以在链上以任何规模进行本地验证。以 LiteSeed 网络为例。它是一个去中心化且经济上安全的 Arweave 打包系统。\r\n\r\n## LiteSeed\r\n这就是我们在 LiteSeed 所做的。我们能够轻松解决其他困难的问题，涉及乐观缓存和交易打包，以提供更快、更便宜、更可靠的上传和处理数据的方式。在实际使用中，数据被发送到 Bundler 并用 AR 支付。然后将其打包并上传到网络。在这种情况下，我们信任 bundler。我们使用 bundler 将多余的 AR 退还给我们。LiteSeed 不同。它通过在 AO 上运行一个 bundler 网络来工作，要求每个 bundler 都要抵押代币。当用户发出请求时，会随机选择一个 bundler，然后将数据上传到 Arweave。\r\n\r\n## Sam\r\n谢谢，团队。在 Forward Research，我们非常关心构建真正的协议。协议令人兴奋，因为它们使我们能够提供以其他方式不可能提供的服务。例如，Arweave 网络运行一个去中心化的存储基金，其机制和风险模型完全透明。一个中心化组织永远无法为你提供相同的保证，因为你总是需要随着时间的推移信任其管理者的执行。大多数智能合约网络试图吸引开发者和用户在它们基本上处于不完整状态时在其上构建，这意味着用户和开发者必须信任创建者执行一个「路障」路线图，以基本完成协议。这里的保证在哪里？有了 AO，我们试图做事情不同。我们将发布的协议主网将是完整的。我们预计将来只需要进行类似比特币风格的更新。随着时间的推移，用户的核心功能和权利将保持不变的小幅升级。这里没有「相信我兄弟」的路线图。只有一个完整且透明的协议，你可以审计并决定是否自己使用。我们还在构建一个不同组织的联盟，每个组织都投入到网络的长期成功中。这里没有所谓的核心团队，从第一天起就是一个去中心化的生态系统。为了支持这种方法，我们还在构建一个不同组织的联盟，每个组织都投入到网络的长期成功中。这个联盟对任何人和所有人都开放，每个人都获得协议的所有权份额。我们已经开始构建了。Tate，你能告诉我们 Community Labs 在 AO 上创建了什么吗？\r\n\r\n## Community Labs\r\n谢谢 Sam。在 Community Labs，我们过去几个月一直在 AO 上构建，我们对它的能力感到震惊。如此之多，以至于今天，我们很高兴地宣布两个新协议：Astro，一种新类型的稳定币，和 Bark，AO 的第一个交易所。让我们来看看 Astro：稳定币对于区块链的采用至关重要，因为它们为用户和开发者提供流动性。为了将这带到 AO，我们构建了 Astro。Astro 是一种超额抵押的稳定币，由 Arweave 代币支持，并为 AO 内部的货币市场奠定了基础。我们认为，这将在 AO 代币的首批交易对以及 Arweave 代币持有者中非常受欢迎。你将能够在 Bark 上交易 Astro 和其他代币，AO 的第一个去中心化交易所。Astro 是 AO 新经济的核心。它被构建为一个自动化做市商，使任何人都能快速简单地交易资产。但为了做到这一点，交易所需要低延迟和高吞吐量。AO 都能照顾到。对在它们自己的过程中生活，意味着你可以并行运行任意数量的它们，导致结算速度远远超过中心化交易所。网络是一个统一的消息格式，任何在网络上构建 EVM 或 Solana 的虚拟机的人都可以与 Bark 接口。这种可组合性允许开发者在任何编程语言中舒适地在 Bark 上构建，甚至在其上构建自治代理。你的交易可以生活在 Bark 上，你的机器人也可以。Bark 从今天开始在 AO 测试网上可用，Astro 将很快推出。在 bark.arweave.dev 上查看，并在 X 上关注我们 communitylabs.com。\r\n\r\n## Sam\r\n谢谢，Tate。AO 最令人兴奋的部分之一是其通用消息格式。它让任何人都可以插入新的和现有的确定性计算系统，无缝地向生态系统中的任何其他参与者发送消息。可以将其视为区块链的通用语言，有点像罗塞塔之星。这意味着它还可以统一现有的智能合约层，成为它们之间的通用桥梁，以 Arweaver 为支柱。但是 Marcin，你能告诉我们 Warp 是如何与 AO 集成的吗？\r\n\r\n## Warp\r\n谢谢，Sam。嗨，我是 Warp 智能合约的创始人Jacob，负责技术。嗨，我是 Warp 的联合创始人 Marcin。我负责业务发展、市场营销和上市。Warp 使 Arweave 的构建者能够在存储链上创建智能合约。我们已经构建了这个平台超过两年了，它目前用于广泛的应用范围。它针对简单的情况进行了优化，比如以原子NFT的形式对内容进行代币化。另一方面，它还使复杂的项目能够作为分布式数据库的基础层。Warp 将作为 AO 生态系统中的一种单独的过程类型工作，保持我们用户请求的所有自定义功能，同时受益于可扩展的 AO 基础设施和与其他过程的互连性。我们很高兴加入 Arweave 构建者的联盟，带来我们启动智能合约生态系统的经验，帮助引入新项目，为开发者提供必要的支持，并增长用户社区。\r\n\r\n## Sam\r\n谢谢。但事情并没有就此停止。MEM，另一个在 Arweave 之上的计算网络，也正在将 EVM 带入 AO。Ben，你能告诉我们你在构建什么吗？\r\n\r\n## Mem\r\nMEM 是一个为 Web3 开发者提供的无服务器函数平台，超越了确定性计算的限制。它可以集成链下 API 和传统 Web 服务。MEM 能够发送触发 AO 合约内部操作的消息，启动代币转移、铸造资产，并使用 Arweave 的代币生态系统。MEM 可以作为 AO 的开放计算 Oracle，运行非确定性程序并访问互联网上的任何数据。这允许 AO 打破确定性验证计算的范围，访问 oracle 化的数据源，为如从其他区块链读取数据到 AO 等新用例打开大门。在系统内部运行传统的 Web2 软件。现在，让我们转到 Outprog，他将谈论 Evervision 和 AO 是如何协同工作的。\r\n\r\n## EverVision\r\nAO 是基于 Arweave 的去中心化计算环境，支持无数并行过程和近乎无限的计算能力，信任最小化。我在 2020 年 11 月提出了 SCP 理论。其核心思想是链下计算和共识数据。凭借 AO 在去中心化数据层中的安全性，促进 SCP 应用之间的无信任通信。这个全球性的去中心化计算机允许动态分配计算资源。Everpay 集成 AO 转变为 AO 网络内的热插拔过程。通过 EverID 实现瞬时、零费用的区块链支付，使 Web3 变得简单。这种集成扩展了 AO 网络的快速链功能，增强了应用程序的互操作性，并实现了无缝 EverID 使用。AO 还将赋能 Everpay，允许更多 SCP 应用消息在 Everpay 上被验证，真正实现去中心化应用的结合。\r\n\r\n## Sam\r\n所以这就是 AO。超并行计算机。关于它还有很多可以说的，但为什么不自己探索一下呢？加入我们的测试网在 ao.arweave.dev。在那里见。","creator":"0x3035a1bbd824041b07f8ab2297a71a81e00127c5","if_to_text_assets_k_v":true,"likes":0,"tags":{},"author_true":"0x3035a1bbd824041b07f8ab2297a71a81e00127c5","space_contract_addr":"0x0","share_holders":[]},{"id":638,"created_at":"2024-02-20T06:54:04.031273+00:00","id_on_chain":13907,"content":"Web3日报

[Web3 101 的播客](https://www.xiaoyuzhoufm.com/episode/65825cf456fd62452069c7cc)，几位在 FB Google 这类大公司做 Crypto 业务的朋友诉苦，听的我很是震惊。\r\n\r\n我从来没在大公司干过，一直在小团队里做事情。小公司的苦是再熟悉不过了，这山望着那山高，很多时候会羡慕大公司有钱有人有用户，似乎啥都不缺。\r\n\r\n实际上，小公司缺的东西，大公司一样缺，不过换了个形式。\r\n\r\n人：大公司有很多优秀的人，但是大公司同样缺适合做创新业务的人，这种人通常不安分，对想做的业务有真正的热情，很容易被大公司的HR给筛掉。在大公司做 Crypto 的员工，一半的人甚至没用过任何 Crypto 产品，这种团队能做出什么样的产品可想而知。\r\n\r\n钱：大公司钱是多，但是愿意投入到创新业务的钱没那么多，而且不持久，一旦热点和人员有变动，钱很容易就断了。AI 火了，核心成员离开了，钱也会掉头就走。\r\n\r\n用户：创新业务很难调用大公司的用户资源，甚至海量用户本身可能会成为创新业务的绊脚石。小公司用户少，影响小，随便发新产品，监管也不会找你。大公司发一个产品可是会影响几亿人的，比如 FB 的稳定币 Libra ，宣布之后就没一天消停日子能过，成天得应付各种部门的监管，最终也没发出来。\r\n\r\n印象很深的一点是，大公司内部讨论做什么产品的时候，经常不是从用户的需求出发的，可能是从怎么做高股价，怎么配合监管，怎么才能不影响主营业务，用户需求的优先级太低了，这样做出来的产品，我想不到有什么竞争力。\r\n\r\n创新就像是在无人的荒野里寻找绿洲，少而精的团队，尽量少但是足够的补给，坚定的信念，高超的野外生存技巧，别想太多，再加上天大的运气，才有机会找到绿洲。这件事注定是海盗干的，而不是海军。\r\n\r\nCrypto 世界依然是荒蛮一片的沙漠，海盗如你我，有福了。拍个脑袋，至少十年内，名不见经传的小人物依然能有机会打下一片天。\r\n\r\n## 值得阅读的文章\r\n\r\n### What Tech Futurists Get Wrong About Human

（1/8）埃及\r\n\r\n\r\n\r\n人口1.08亿，官方语言阿拉伯语，伊斯兰教为主要宗教，主体民族为埃及人。埃及是阿拉伯世界人口最多的国家，也是非洲大陆人口第三多的国家。面积101万平方公里。被认为是中东、北非、穆斯林世界的地区强国。政治稳定。\r\n人口主要集中在尼罗河谷和三角洲地区，98%埃及人居住在3%的土地上。\r\n\r\n埃及有大量没有银行账户的人口。世界银行18年报告显示，多达67%的15岁以上人口没有银行账户。\r\n世界银行19年报告显示，埃及是全球接受汇款最多的五个国家之一(仅次于印度、中国、墨西哥和菲律宾) 。\r\n埃及没有银行账户的成年人通过现金或柜台服务接受国内汇款。\r\n\r\n13年一叙利亚人在Facebook创立一个比特币小组，来参与的10000多人中，大多数是埃及人；\r\n16年埃及法币曾一夜贬值48%，促进了加密货币的采用；\r\n17年埃及的加密访问率已经较高；\r\n17年埃及央行曾表示银行不会跟加密货币打交道；\r\n18年初，埃及的最高伊斯兰宗教领袖曾说根据伊斯兰教法，加密货币是不合法的\r\n\r\n19年加密电子邮件服务Dmail由一家埃及公司推出；\r\n19年埃及国家银行参与了R3的Corda区块链建立的贸易金融程序的测试；\r\n19-20年间，埃及LocalBitcoins的注册和交易量增长了100% ；\r\n20年9月禁止在没有埃及央行许可证的情况下发行、交易或推广加密货币；\r\n21年，埃及国家银行与Ripple合作支持跨境支付；\r\n\r\n21年1月，埃及在英国加密货币交易所http://CEX.IO上的用户注册比前一个月增加了250%；\r\n21年4月，埃及央行宣布允许银行在监督下发行数字货币；\r\n从去年12月到今年1月，http://CEX.IO 在埃及的比特币交易量也增长了400% 以上\r\n21年中到22年中，埃及加密增幅很大，交易量增长了两倍多\r\n\r\n埃及相关的Web3项目有金融科技Money Fellows（22年底融资3100万美元）、Web3气候科技Thallo（22年底融资250万）、消费金融Telda（22年底融资2000万）（获得了埃及央行的许可，将以数字形式发行银行卡并提供客户服务）等等。\r\nWeb3沉浸式社交应用VUZ的约四分之一用户来自埃及。\r\n\r\n\r\n## （2/8）苏丹\r\n\r\n人口4800万，官方语言为阿拉伯语、英语，伊斯兰教为主要宗教，主体民族为苏丹阿拉伯人。面积190万平方公里，非洲第三大国。2011年南苏丹从苏丹独立，独立前苏丹比较依赖石油收入，但南苏丹独立带走了75%的油田。苏丹目前政治不太稳定，被认为是世界上最腐败的国家之一。\r\n\r\n21年苏丹通货膨胀率约360%；\r\n22年初苏丹央行曾警告公民不要使用加密货币，风险包括金融犯罪、盗版、价值损失等；\r\n22年初在欧洲工作的苏丹医生Mo曾讲述他经历过多次法币价值大幅波动，这促使他在15年转向比特币，汇款逐渐也都用加密货币形式，主要通过比特币闪电网络进行。\r\n\r\n入选YC的苏丹创业公司Bloom希望利用稳定币帮助的非洲人避免通货膨胀问题。\r\n由沙特王储领导的主权财富基金推出了专注于中东科技行业的240亿美元投资基金，该基金由PIF管理。PIF将在巴林、阿曼、苏丹、约旦和伊拉克建立五家独立的投资公司。\r\n\r\n## （3/8）阿尔及利亚\r\n人口4500万，官方语言为阿拉伯语、Tamazight，伊斯兰教为主要宗教，主体民族为阿拉伯人。面积240万平方公里，为非洲最大国家。\r\n国家经济比较依赖于石油和天然气等资源。21世界初内战结束后，政治相对稳定。阿尔及利亚境外最大的阿尔及利亚移民集中地是法国。\r\n\r\n17年曾表示考虑禁止加密货币。\r\n在Chainalysis发布的2020年加密地图中，阿尔及利亚与阿富汗、佛得角、乍得、斐济、老挝、利比亚和蒙古国并列为加密采用指数最少的国家。\r\n\r\n## （4/8）摩洛哥\r\n人口4000万，官方语言为阿拉伯语、Amazigh，伊斯兰教为主要宗教，主体为阿拉伯人、柏柏尔人。面积为45万（或71万，争议领土）平方公里。除东南部沙漠地区外，其气候、地理与欧洲的伊比利亚半岛类似。服务业为主。1956年独立以来，政治一直相对稳定。\r\n\r\n摩洛哥是世界上银行业最不发达的国家之一。19年时只有29%的摩洛哥成年人能使用银行账户，这远远低于中东北非地区44%的平均水平。\r\n\r\n13年骑手Borja和Elvis曾穿越非洲多个国家，靠向当地人支付比特币为生，就途径过摩洛哥的西撒哈拉地区（争议地区）；\r\n\r\n17年初摩洛哥外汇管理局禁止加密货币交易；\r\n18年摩洛哥以欺诈罪将一名经营“Bitcoin Store”交易所英国公民引渡到美国；\r\n21年初摩洛哥央行调研发行央行数字货币的事项；\r\n21年2月是点对点比特币交易平台LocalBitcoin在摩洛哥交易量方面有史以来最好的一个月；\r\n\r\n22年初摩洛哥是非洲Web3明星创业项目Jambo在北非唯一设立办事处的国家；\r\n22年中，Metamask公布的数据，Web3增长最快的国家包括摩洛哥、阿联酋、中国和土耳其；\r\n23年1月，摩洛哥央行宣布加密法律草案已出。\r\n\r\n## （5/8）突尼斯\r\n人口1200万，官方语言为阿拉伯语，伊斯兰教为主要宗教，主体为阿拉伯人。面积16万平方公里。\r\n14-20年，被认为是阿拉伯世界唯一的民主国家，并在21年指数中被评为混合政权。是非洲少数几个人类发展指数排名较前的国家之一，是非洲大陆人均收入最高的国家之一。\r\n政局相对稳定。\r\n\r\n2015年，BitOasis比特币钱包的初始用户来源之一即突尼斯；\r\n同年，突尼斯通信技术部曾公布需区块链知识的实习生的职位空缺；\r\n同年，突尼斯的邮政服务报告试验了一种加密支付应用程序；\r\n19年底，传言突尼斯会发行加密债券、央行数字货币，后突尼斯央行承认有考虑央行数字货币，但否认了将要推行；\r\n\r\n20年初，联合国儿童基金会资助了突尼斯创业项目Coinsence，主要做线下社区代币，居民们主要使用这种代币支付志愿者工作费用，“努力构建非投机性、属于公共资源的货币”；\r\n21年，突尼斯财政部长称比特币所有权应该非罪化；\r\n21年Q1，http://CEX.IO等交易所的突尼斯用户注册数量同比增长了11% 。\r\n\r\n## （6/8）利比亚\r\n人口700万，官方语言为阿拉伯语，伊斯兰教为主要宗教，主体为阿拉伯人。面积176万平方公里。\r\n政局相对不稳定。\r\n上世纪80年代初，利比亚人均GDP一度高于一些发达国家。\r\n14年第二次利比亚内战开始，17年60%人口营养不良，20年签署永久停火协议，但政治对抗仍在持续。\r\n经济依赖石油。\r\n\r\n13年比特币ATM机就曾经在利比亚做过推广；\r\n17年，利比亚央行主要控制的总部位于巴林的阿拉伯银行加入R3 distributed ledger consortium，是第一个加入R3的中东北非地区的银行。\r\n\r\n## （7/8）毛里塔尼亚\r\n人口460万，官方语言为阿拉伯语，伊斯兰教为主要宗教，民族相对复杂，主体为Haratin、阿拉伯柏柏尔人。面积100万平方公里。\r\n自然资源丰富但贫穷，是世界上最后一次废除奴隶制的国家。政治相对稳定，19年选举被视为独立后最高权力首次和平交接。\r\n暂未搜索到其Web3相关重要信息。\r\n\r\n## （8/8）撒拉威\r\n人口60万或70万，官方语言为阿拉伯语、西班牙语，伊斯兰家为主要宗教，面积27万平方公里。得到45个联合国会员国的承认。\r\n13年骑手 Borja 和 Elvis曾穿越非洲多个国家，靠向当地人支付比特币为生，就途径过撒拉威的西撒哈拉地区（争议地区），也同样可以使用比特币。\r\n\r\n总结来说，北非8国阿拉伯语为主要官方语言，伊斯兰教为主要宗教。相对非洲其他地区，北非国家普遍存在主体民族，多为阿拉伯人，发展程度相对较好。\r\n\r\n从Web3角度看，较受关注的国家主要是埃及、摩洛哥等。埃及人口过亿，是地区强国，接触加密早，Web3生态较发达；摩洛哥增长快，政府相关政策可能会很快出台，有望走向合法化。\r\n\r\n信息来源为多个国内外Crypto媒体、英文维基百科、部分官网和其他社交平台，做了大量查询、梳理工作，若认可还请大家多转发点赞评论支持，期待多交流。\r\n也欢迎关注我们3WW3亚非拉Web3研究院\r\n@Research3ww3","creator":"0xa4059ef885538373e236975f1abc9e2f23b82715","if_to_text_assets_k_v":true,"likes":0,"tags":{},"author_true":"0xa4059ef885538373e236975f1abc9e2f23b82715","space_contract_addr":"0x0","share_holders":[]},{"id":541,"created_at":"2023-12-26T06:27:04.016022+00:00","id_on_chain":13711,"content":"#

I made an e-commerce platform and users just come to consume; I made a chat software and users just use it... Even if there is some room for creation, it is nothing more than the publisher. Condescend to \"give\" opportunities to the community, such as **\\*\\*Mini Programs**.\r\n\r\nBut in the Web3 world, we can achieve **give the community unlimited space for creativity**. For example, I released an \"ultra-lightweight digital identity protocol MoveDID\", for example, I released an \"ultra-lightweight content asset protocol Bodhi\". Based on these protocols, the community can create countless apps without permission. For example, the original author only did one thing - build a foundation, then the community grew, and eventually a castle grew. 🏰\r\n\r\n  ## 0x02 The Power of Indie Hacker\r\n\r\nAnother interesting thing is that Bodhi is completely implemented by an independent developer `Luyao`:\r\n\r\n> https://twitter.com/levi0214\r\n\r\nThis year NonceGeekDAO has a focus, which is **\"The Rise and Future of Independent Developers\"**.\r\n\r\nAnd I have written several articles on this basis:\r\n\r\n> [Web3.0 super individuals will appear among digital nomads](https://mp.weixin.qq.com/s?__biz=MzI0NTM0MzE5Mw==&mid=2247487063&idx=1&sn=afd9635547b0fda8933d21a527b779d9&chksm=e94eb8e1de3931f7f43f038051742c1f226aeca168f7d0684eaeef264b61f3b48b6b756627a5&scene=21#wechat_redirect)\r\n>\r\n> [Digital nomad life can release a lot of mental resources](https://mp.weixin.qq.com/s?__biz=MzI0NTM0MzE5Mw==&mid=2247487518&idx=1&sn=e98049ef2086e53b3cc7e41e16f544f1&chksm=e94ea6a8de392fbe28e28ede16cc1e77dfa104dea8de0286b0c65145f264d559cfaad4969585&scene=21#wechat_redirect)\r\n>\r\n> [Digital Nomad: Return to the ancient lifestyle of \"body and mind integrated\"](https://mp.weixin.qq.com/s?__biz=MzI0NTM0MzE5Mw==&mid=2247487148&idx=1&sn=ea31026a98f5242e111c3cca43871813&chksm=e94eb81ade39310cb3437de9c0a18b27e65561993f5760733b50e7d6ad8790a32e694e1bb6ec&scene=21#wechat_redirect)\r\n\r\nToday I will make some additions to the above thoughts.\r\n\r\nWe are currently in an era where everything is accelerating, and conflicts between people continue to intensify. Under this inevitable trend, large-scale organizations gradually become difficult to survive. Internal entropy continues to increase, and most energy is used to solve internal friction. After internal friction cannot be solved, the organization will fall apart or become a zombie.\r\n\r\nIn this case, it is easier for independent developers or extremely streamlined small teams to achieve their own self-consistency. Therefore, the products built by this kind of team will have stronger vitality - this is a core anti-consensus view of NonceGeekDAO.\r\n\r\nProductivity, the core constraint of small teams in the past, will be solved with the rapid development of AI technology. Using AI well, independent developers and minimalist small teams will have `^10 Members`!\r\n\r\nSo let’s come to a conclusion: “Small mammals” have survived in the violently turbulent ancient times instead of “large dinosaurs”. The same thing will happen to “minimalist small teams” and “large organizations”.\r\n\r\n**❤️Love & Peace.❤️**\r\n\r\n\r\n\r\n\r\n\r\n\r\n","creator":"0x73c7448760517e3e6e416b2c130e3c6db2026a1d","if_to_text_assets_k_v":true,"likes":0,"tags":{},"author_true":"0x73c7448760517e3e6e416b2c130e3c6db2026a1d","space_contract_addr":"0x0","share_holders":[]},{"id":478,"created_at":"2023-12-18T08:14:04.977986+00:00","id_on_chain":10534,"content":"Bodhi 是一个让我感到非常激动的产品，这两天总是思来想去，想找些朋友聊聊 Bodhi，很遗憾，找不到知音。Bodhi 可能是币圈非常罕见的，在金融领域之外有正外部性的产品，未来一切的内容和公共物品的融资，都会发生在 Bodhi 之上。\r\n\r\nCrypto 对于你的价值是什么？对我来讲他是 not your key not your money，他是给每个人平等和自由，我相信 Crypto 是未来真正可以改变世界，让每个人生活更美好，消除现实世界里的诸多丑恶。\r\n\r\n我热爱 DeFi，我觉得 DeFi 很酷、DeFi 很棒，DeFi 的公式里充满了数学的美感，DeFi 协议从金融角度都是完美的，是当下世界里一大部分迂腐秩序的完美替代品。但是 DeFi 总是让我感觉有所欠缺，我不知道 DeFi 如何改变世界上诸多不平等、贫穷和饥饿。\r\n\r\n当然， DeFi 本身也发挥了足够的作用，DeFi 让世界更平等了，我只能对 Crypto 报以美好预期，希望总有一日，我们能见到一个更美好的世界，运行在区块链和代码之上。\r\n\r\n直到，我看到了 Bodhi，Bodhi 是那么简单、却又那么强大、却又真正的给这个世界创造正外部性。周四下午看到了 Bodhi 发布的推特，只有晚上才有空看完 luyao 的第一篇文章，辗转反侧，觉得必须氪金以明志，在凌晨 2 点半的时候在按硬件钱包买入 #0。\r\n\r\n作为一个 PM，我有些嫉妒 luyao，为什么他这么酷、这么棒、能做出这么好的产品。我强烈建议大家读读 Bodhi 的 #0 号内容，About Bodhi，给了我非常大的启发，我觉得像是打开了新世界的大门，如果大家有兴趣，可以再读读 luyao 的推特和博客 lol\r\n\r\n我热爱 Crypto，我喜欢 Crypto 背后的自由与意义，我喜欢讨论公共物品、讨论 Self Custody。每天我出门上班，在路边看车辆飞速掠过，我总是在幻想，可能此时有无数条区块链节点正在发出安静的嗡嗡声，对交易达成共识，形成一个不可篡改的全球状态，这一切真是太美妙了。\r\n\r\n我自视清高、讨厌炒币，对投机嗤之以鼻，见到 memecoin、铭文就头疼，但是看到这篇推特后，我觉得非常愧疚，我觉得我实在太狭隘了，我不但被 luyao 的产品理念折服，我也被他的开放心态而折服。\r\n![](https://arweave.net/n-9jWioKo51oJfnIUVe6Rdr5-ul051PTsh48LSxBnNc)\r\n\r\n只要你付出了 Gas，你就有权利在这个全局状态服务器上，永久的添加一笔内容。当然，BTC 要不要过滤铭文就是另一个话题了，每个公共区块链都需要考虑自己的 anti-spam 策略，来保证网络安全和符合设计者的初衷，今天晚上 Arb 的铭文把排序器打挂了，这显然就很不合适 :(\r\n\r\n讲远了meme 也并不邪恶，在我疯狂向身边朋友 shill Bodhi 的时候，我突然发现，我的行为有些像一个 memecoin 持有者，只是有一个简单的、其他人无法理解的信念、爱好，多喜欢别人可以多听听自己的声音，多理解一下自己。Afterall, We humans are spiritual beings.\r\n\r\n\r\n> Moreover, people often think of Meme and Ponzi as insignificant or even evil.

Although it may be a \"hot cake\" to rush in now, I still jumped into the inscription market out of FOMO. After calming down, I had some questions: 1. BTC does not have smart contracts, so how is buying and selling in the inscription market implemented in a single transaction? 2. At the same time, I noticed that the transaction is initiated by the buyer, does the seller not need to confirm the transaction? Doesn't this make the seller vulnerable to attacks?\r\n\r\n## Reflections\r\n\r\nI recalled the BTC course I studied many years ago, and the first question was relatively easy to understand. A BTC transaction (Tx) contains multiple inputs and outputs. For example, the first input is the buyer's BTC, the second input is the seller's inscription, the first output is the buyer receiving the inscription, and the second output is the seller obtaining BTC. This completes the transaction in a single Tx.\r\n\r\nHowever, the second question completely stumped me. The Tx input contains the seller's address, so the transaction definitely requires authorization from the seller. However, in the frontend interaction, it seems that the buyer does not need the seller's confirmation when triggering the transaction (although it cannot be ruled out that there may be backend confirmation). Does this mean that the seller has already signed the transaction when placing the order? But when the seller places the order, they do not know the complete output of the transaction, so how can they sign it? If only the inputs are signed, the seller can easily be attacked. Is there a centralized node involved in this process?\r\n\r\n## Verification\r\n\r\nWith a series of questions about the second issue, I deployed a brc20 script in the Ouyi trading market and conducted experiments with buying and selling. After the experiment, I became even more confused because I didn't know what role Ouyi played in the middle and whether it secretly used my wallet to sign the entire transaction on behalf of the seller. What I can be sure of is that there was definitely no on-chain operation when the seller placed the order.\r\n\r\nDue to the high transaction costs of BTC, I couldn't bear to do more experiments, so I had to resort to theoretical deduction.\r\n\r\nFirst, I assume that Ouyi will not secretly use my wallet to sign when the buyer appears without my confirmation, so I must have authorized the transaction when placing the order. But when I placed the order, there was no buyer yet and the transaction had not been constructed, so what did my signature authorization authorize? In the end, it can only be explained that I can authorize some inputs and outputs of the transaction. Thinking of this, I decisively used ChatGPT to analyze my previous transactions, and finally, it indeed verified my deduction.\r\n\r\nFirst, I asked ChatGPT, \"What does the signature content of the input address include in BTC transactions?\" Then I asked, \"Are there any special cases where the signature does not need to include the outputs, or includes only some of the outputs?\"\r\n\r\nAnd sure enough, it told me the truth:\r\n\r\n\r\n> In the Bitcoin system, there are indeed some special cases where the signature may not include all outputs or handle outputs in a specific way. These cases mainly involve different types of signature hash (SIGHASH) types. The SIGHASH type determines which parts of the transaction are included in the signature and how they are included. Here are some common SIGHASH types:     \r\nSIGHASH_ALL: This is the default signature type. When using SIGHASH_ALL, the signature includes all inputs and outputs. It guarantees that the entire content of the transaction cannot be changed.  \r\nSIGHASH_NONE: This type of signature only protects the inputs of the transaction, not the outputs. A transaction signed with SIGHASH_NONE allows anyone to change the output portion of the transaction without invalidating the signature. This means that the signer agrees to any type of output or does not care how the outputs are allocated.  \r\nSIGHASH_SINGLE: SIGHASH_SINGLE allows the signer to only sign a specific output (the output corresponding to the input being currently signed). For example, if there are three inputs and three outputs, the first input will only sign the first output. This allows other outputs to be changed without affecting the validity of the signature.     \r\nSIGHASH_ANYONECANPAY: This is a modifier that can be used in conjunction with the above types. It allows the signer to sign only a specific input instead of all inputs of the transaction.\r\n>\r\n\r\nThat means the seller may indeed only sign some of the inputs and outputs, so I conducted further verification. Here is the transaction from yesterday: [Tx](https://www.blockchain.com/explorer/transactions/btc/f8d0350cc032f21e1055887d3a6baadb5ad949e66ca0ae61c27080b2346ad7f7)\r\n\r\nThe third input corresponds to the seller's script, and its witness data is ”9fc4d93b3a0a766aa6bb2d6defe00c52f5e5ec4a7a3cc08d7c1007197fb2b6e57bf560448a62328f53998d7f5e5ef351db6c74d80b784c0ab245361996dcc74383“\r\n\r\nAnd GPT tells me:\r\n\r\n> To determine the SIGHASH type, you need to decode the signature data for the corresponding input. In SegWit transactions, this data is located in the **`witness`** field of the transaction. For the third input in the transaction you provided, you need to decode the following **`witness`** data:\r\n\"9fc4d93b3a0a766aa6bb2d6defe00c52f5e5ec4a7a3cc08d7c1007197fb2b6e57bf560448a62328f53998d7f5e5ef351db6c74d80b784c0ab245361996dcc74383\"    \r\nThis data is part of the signature information. The SIGHASH type is typically located at the end of the signature as a single byte. Bitcoin's SIGHASH types include the following:  \r\nSIGHASH_ALL (default): **`01`**.  \r\nSIGHASH_NONE: **`02`**.  \r\nSIGHASH_SINGLE: **`03`**. \r\nSIGHASH_ALL | SIGHASH_ANYONECANPAY: **`81`**.   \r\nSIGHASH_NONE | SIGHASH_ANYONECANPAY: **`82`**.    \r\nSIGHASH_SINGLE | SIGHASH_ANYONECANPAY: **`83`**. \r\n> \r\n\r\nThe last byte is 83, isn't that corresponding to SIGHASH_SINGLE | SIGHASH_ANYONECANPAY?\r\n\r\nGPT:\r\n\r\n> Your understanding is correct. If the last two digits of the signature data are **`83`**, it indicates the use of the **`SIGHASH_SINGLE | SIGHASH_ANYONECANPAY`** type of signature hash (SIGHASH).  \r\nIn Bitcoin transactions, **`SIGHASH_SINGLE | SIGHASH_ANYONECANPAY`** is a special type of signature that has the following meanings:\r\n**SIGHASH_SINGLE**: The signature only guarantees the association between the signer's specific input and output. This means that the signer is only concerned about how the specific input they are signing affects the corresponding output.  \r\n**SIGHASH_ANYONECANPAY**: This option indicates that the signature only guarantees one input in the transaction, allowing others to add more inputs to the transaction without affecting existing signatures.  \r\nWhen used together, **`SIGHASH_SINGLE | SIGHASH_ANYONECANPAY`** allows for a flexible transaction type where the signer is only responsible for their specific input and corresponding output, while allowing others to add additional inputs to the transaction without interfering with existing signatures.  \r\nThis type of signature can be very useful in certain complex transaction scenarios, such as certain multi-party transactions or smart contract applications. It provides greater flexibility, allowing multiple participants to independently sign for their respective inputs and outputs without affecting each other.\r\n> \r\n\r\nI have also confirmed that the specified output by the seller (i.e., the amount of BTC received by the seller) is in the third position of the Tx, and it matches the index of the seller's input. The GPT also mentioned, \"This means that if you choose to sign the third output of the transaction using SIGHASH_SINGLE, you will only sign the third output.\" So everything matches up.\r\n\r\n## Summary:\r\n\r\nWhen the seller places an order, they specify one input and one output in the Tx, which is the plaintext being sold and the expected amount of BTC received. They then sign it and send it to the backend of the trading market.\r\n\r\nAfter receiving the partially signed Tx from the seller, the backend of the trading market displays the order on the market page.\r\n\r\nWhen a buyer sees the order on the market page and chooses to buy, the wallet completes the entire Tx, signs it, and broadcasts it.\r\n\r\nFrom this point on, when the Tx is confirmed on the blockchain, the entire transaction is completed.\r\n\r\n## Closing words:\r\n\r\nIn the cryptocurrency world, one day is like a year in the human world, and there is so much to learn!","creator":"0x3ae0e8df7bff48d2a2084515abddc393fb805b7f","if_to_text_assets_k_v":true,"likes":0,"tags":{},"author_true":"0x3ae0e8df7bff48d2a2084515abddc393fb805b7f","space_contract_addr":"0x0","share_holders":[]},{"id":455,"created_at":"2023-12-18T03:39:06.123146+00:00","id_on_chain":7783,"content":"

中本聪的邮件\r\n\r\n\r\n在提及比特币时，闪电网络绝对是一个绕不过去的关键词。\r\n\r\n在早些年，大众对比特币理解很少，比特币布道者的角色也没有这么多，因此直接询问中本聪是获得明确答案的唯一途径。2011 年，软件开发人员 Mike Hearn 在任职 Google 的高级软件工程师和技术主管时，也将许多精力用于比特币开发。在大约五年的比特币开发时间里，Mike Hearn 通过电子邮件与中本聪进行了各种对话，之后在自己的博客中将其作为具有历史意义的文件发布。\r\n\r\n2011 年 3 月 7 日，Mike Hearn 刚刚使用 Apache 2 许可证以 Google 名义了发布 BitCoinJ（一个使用 Java 构建并实现比特币网络协议的开源比特币客户端库），准备在接下来的一两个月里完成完整客户端模式的实现。\r\n\r\n他给中本聪发去邮件，询问：「我还没有完全理解，为什么序列号是 TX 输入的属性，而不是 TX 本身呢？」\r\n\r\n\r\n\r\n对此，中本聪的回复是：「中间交易事务不需要广播，只有最终结果才会被网络记录下来。就在 nLockTime 之前，各方和一些见证节点广播了他们看到的最高序列 tx。」这是中本聪对支付通道的解释，也正是闪电网络的雏形，其正统性的诞生。\r\n\r\n\r\n如果要追溯到更早，Bitcoin 0.1 就包含了一个代码草稿，是允许用户在交易被网络确认之前更新这笔交易的。\r\n\r\n\r\n## 闪电网络话事人：Blockstream 和 Lightning Labs\r\n\r\n\r\n支付通道和网络设计经过了多年的演变，因为 2015 年初比特币闪电网络白皮书的发布，发展逐渐明晰起来。意外的是，在这之后的几个月，整个 2015 年的春天和夏天，比特币的扩展问题和区块大小上限的分歧演变成了公开的争执。\r\n\r\n\r\n\r\n2015 年 12 月，Gregory Maxwell（Blockstream 的创始人之一）在比特币开发者邮件中提出了一份扩展方案路线图，其中包括了闪电网络这一重点。比特币技术社区大部分人对这份比特币系统容量增加表示支持，并在 Bitcoin Core 项目中实施。这一下，就激发了大家对闪电网络的期待。之后的比特币扩容之争，意外得把闪电网络推上了风口浪尖之上。\r\n\r\n\r\n\r\n\r\n### 「比特币大厂」 Blockstream\r\n\r\n\r\n民间似乎一直有这么一个传言：Blockstream 是比特币背后的「话事人」。这样的传言，并不是空穴来风。\r\n\r\n\r\n\r\n2014 年 10 月 23 日，建设闪电网络最有影响力之一的公司 Blockstream 成立，hashcash 的发明者 Adam Back 集齐了 Matt Corallo、Greg Maxwell、Pieter Wuille 等多位比特币开发者创立了 Blockstream 公司并放出了他们的侧链白皮书。\r\n\r\n\r\n\r\n自成立以来，Blockstream 一直是研发闪电网络的先锋。身为 Blockstream 的创始人，Adam Back 的影响力不容小觑。在国外一份「加密货币」影响力排行榜中，Adam Back 名列第四，前三位分别是：Andreas Antonopoulos(比特币早期布道者)、V 神（以太坊创始人）、尼克萨博 (「智能合约」概念提出者)。\r\n\r\n\r\n\r\n要说 Adam Back 的影响力这么大的原因，还得追溯到 1997 年。当时互联网刚刚兴起，电子邮件被当做是当时人们联络的第一应用，然而大量的垃圾邮件让人们不堪其扰，许多人都开始尝试解决的办法。Adam Back 发表了一篇主题为《A partial hash collision based postage scheme》的邮件，在邮件中，他向人们介绍了 Hashcash 这种使用一种叫工作量证明（proof of work）的技术来防止垃圾邮件的机制。因此 Adam Back 也常被称为「PoW 之父」。\r\n\r\n\r\n\r\n而这些，都因为中本聪在比特币白皮书中提到了 Adam Back 的「Hashcash」，而使其知名，并逐步奠定了其在加密行业里强大的地位。\r\n\r\n\r\n\r\n\r\n\r\n\r\n\r\nBlockstream 的创始成员和主要贡献者中，也不乏比特币开发团队的关键成员，如 Greg Maxwell 和 Pieter Wuille。\r\n\r\n\r\n\r\nGreg Maxwell 著名的加密学家和软件工程师，对比特币的隐私和可扩展性做出了重要贡献。例如 BIP32 中使用的同态密钥推导，以及 CoinJoin 和盲法证明等无信任隐私保护技术。Pieter Wuille 自 2011 年 5 月以来一直是 Bitcoin Core 开发人员。2012 年，Wuille 发布了 BIP 32，为比特币添加了分层确定性钱包，还参与了隔离见证 (SegWit) 等关键技术的开发。\r\n\r\n\r\n\r\n虽然从理论上讲，任何人都可以为 BTC Core 项目贡献代码，但只有那些拥有提交访问权限的人才能将该代码合并到实际的 BTC 协议中。Pieter Wuille 是当时仅有的能提交 BTC 代码存储库访问权限的五个人之一，也是继中本聪之后为 BTC 项目贡献最多代码的人。\r\n\r\n\r\n\r\n在 2015 年比特币社区关于扩容的讨论日渐火热时，一篇苏黎世理工的论文《A Fast and Scalable Payment Network with Bitcoin Duplex Micropayment Channels》于 2015 年晚期发布。这篇论文的解决方案重度依赖于时间锁来作为通道有效性的「倒计时装置」，以及一种叫做「无效树」的密码学技巧来作废陈旧的通道交易。这也成为了后来闪电网络赖以为生的技术原型。而这篇论文的两个作者 Christian Decker 和 Roger Wattenhofer 后来都加入了 Blockstream。\r\n\r\n\r\n\r\n意外的是，在这之后的几个月，甚至整个 2015 年的春天和夏天，比特币的扩展问题和区块大小上限的分歧演变成了公开的争执。2015 年的 8 月 15 日，两位比特币的早期技术先驱，Gavin Andresen 和 Mike Hearn 联手在博客中宣布，他们的新版 BitcoinXT 会实现 BIP-101 提案，而这并不需要经过矿工的投票，直接就会激活。这一天，后来被大家称为「区块大小战争爆发日」，在这期间 Blockstream 为闪电网络的推动做出了极大贡献。\r\n\r\n\r\n\r\n2015 年 12 月，Gregory Maxwell（Blockstream 的创始人之一）在比特币开发者邮件中提出了一份扩展方案路线图，其中包括了闪电网络这一重点。比特币技术社区大部分人对这份比特币系统容量增加表示支持，并在 Bitcoin Core 项目中实施。这一下，就激发了大家对闪电网络的期待。\r\n\r\n\r\n\r\n当时关于 Bitcoin Core 开发团队和比特大陆之间的争议，存在两种截然不同的观点。\r\n\r\n\r\n\r\n一方面，比特大陆的支持者认为，Bitcoin Core 开发团队是一群固执的程序员，坚守着原始的比特币内核，拒绝进行必要的变革和适应。他们认为这些开发者沉浸在自己的技术世界里，忽视了比特币发展的真正需求，是阻碍进步的「老家伙」。另一方面，Bitcoin Core 开发团队的支持者则认为比特大陆是利用其在行业中的影响力和信息优势，故意歪曲事实，误导公众和矿工。\r\n\r\n\r\n\r\nBlockstream 联合创始人 Adam Back 代表比特币开发者和双方的调解者，来到香港参加共识大会。作为最早的区块链开发公司，Blockstream 的公司不仅与 Bitcoin Core 互有人员交集，而且资助他们的开发工作。Blockstream CEO Adam Back 的签名让大家以为开发者同意了香港共识。\r\n\r\n\r\n\r\n\r\n\r\n\r\n\r\n但在会后，Bitcoin Core 却表示在会议上承诺各种改动的开发者全都是没有 Core 源代码修改权限的程序员。有权利改动 Core 源代码的五个人一个都没有出席，更没有签名。\r\n\r\n\r\n\r\nAdam Back 也表示，他在会议上签名仅代表个人，无法代表 Bitcoin Core 同意香港共识。他本人态度直接转了 180 度，强烈反对自己不久前亲手签署的香港共识。香港共识遭到了 Bitcoin Core 的拒绝承认，但同一时期，闪电网络却得到了比特币开发者的「正统性」共识。\r\n\r\n\r\n\r\n2017 年夏，隔离见证在比特币区块链上激活，为闪电网络的实施铺平了道路。可以说，Greg Maxwell 和 Pieter Wuille 在比特币网络的升级——特别是隔离见证（SegWit）的引入和闪电网络的开发中，发挥了至关重要的作用。\r\n\r\n\r\n\r\n由于 Blockstream 雇佣较多 Bitcoin Core 的开发者，使得 Blockstream 在比特币开发上有很大话语权，招致了很多批评。比如，有人说 Blockstream 实际上控制了比特币的开发 (甚至有人说 Blockstream 在比特币社区中使用水军，打压反对者，控制舆论)。根据 Whale Calls 的分析，比特币代码的更新中，有 12%-20% 来自 Blockstream 的开发者。\r\n\r\n\r\n\r\n几年前，社区对 Adam Back 的大多分析都是他想从比特币中牟利。因为 Blockstream 的商业模式就是销售侧链/闪电网络产品服务，如果区块扩容，侧链/闪电网络也就无用武之地，那么作为一家以盈利为目的的公司 Blockstream 也就无法获得收益。\r\n\r\n\r\n\r\n### Lightning Labs：闪电网络白皮书作者分道扬镳\r\n\r\n\r\nLightning Labs 最大的正统性，或许就来自其创始人，正是闪电网络白皮书的作者 Joseph Poon 和 Tadge Dryja。\r\n\r\n\r\n\r\n在 2015 年秋天，这家总部在旧金山的初创公司，由 Elizabeth Stark 牵头发起，集结了闪电网络白皮书的两位共同作者 Joseph Poon 和 Tadge Dryja 开始创业，与 BlockStream 鼎足而立。两者最大的区别是，Lightning Labs 用的是 Go 编程语言，Blockstream 则用的是 C 编程语言。\r\n\r\n\r\n\r\nLightning Labs 不仅在闪电网络的理论基础上做出了关键贡献，还在 2018 年 3 月发布了闪电网络的 beta 版本，这一举措标志着闪电网络发展的一个重要里程碑。\r\n\r\n\r\n\r\nLightning Labs 的早期团队与 Blockstream 相比，丝毫不落下风。\r\n\r\n\r\n\r\n在撰写闪电网络白皮书之前，Dryja 创立了点对点的交易系统 mirro，并且加入了预测市场的概念，同时也研究过过一个 PoW 算法 Hashimoto，这是 Dagger Hashimoto 算法的前身，而后者则是以太坊 PoW 算法 ethash 上线之前的替代算法。\r\n\r\n\r\n\r\n除了 Dryja 之外，闪电网络白皮书的另一位作者 Poon 也是一位加密行业的顶级开发者。例如最近 Vitalik 新发文支持回归的 Plasma ，正是他和 Poon 两人在 2017 年联合推出的以太坊二层扩展技术，两人是共同致力于可扩展性项目的强大搭档。同时，Poon 还曾做过一个继承了 namecoin 思想的项目 handshake。\r\n\r\n\r\n\r\nElizabeth Stark 则作为 Lightning Labs 的联合创始人兼首席执行官，在加密货币和开放互联网领域享有盛誉，是一位知名的企业家和教育家，在比特币社区中有着显著的影响力。\r\n\r\n\r\n\r\nOlaoluwa Osuntokun (Roasbeef) 是 Lightning Labs 的另一位联合创始人，也是一位杰出的比特币开发者，对闪电网络的研发做出了重要贡献。他在 lit 协议基础上研发出了 lbd 协议，得到了更多开发者的认可。\r\n\r\n\r\n\r\n在 lightning labs 的工程师中，不得不提到 Alex Akselrod。早在闪电网络白皮书发布的 4 个月前，Alex Akselrod 第一次提出了双向支付通道的提案。核心思路是引入递减时间锁，可以让接收者有限次的发送资金给发送者。Alex Bosworth 曾通过与 Bitrefill 建立闪电通道支付了自己的电话账单，创造了闪电网络上的第一笔交易。\r\n\r\n\r\n\r\n然而在 2016 年底，在这家闪电网络公司刚成立一年时，两位闪电网络白皮书作者，因为一场「争吵」而分裂。\r\n\r\n\r\n\r\n就职 Lightning Labs 时，Dryja 开发的首版协议名为 LIT，与 Blockstream 研发的 BOLT 并不兼容，但 Lightning Labs 的 CTO Olaoluwa 开发的 LND 协议与 BOLT 兼容，逐渐得到更多开发者的认可，完成了后来者居上。\r\n\r\n\r\n\r\n因此 Lightning Labs 便决定专注于 LND，Dryja 则选择离开 Lightning Labs，转而加入麻省理工学院媒体实验室的研究社区，继续开发 Lit。有趣的是，这个研究社区也雇用了 Bitcoin Core 的顶尖开发者 Wladimir van der Laan 和多位 Bitcoin Core 的贡献者。\r\n\r\n\r\n\r\n就此，两位闪电网络白皮书的作者 Joseph Poon 和 Tadge Dryja，分道扬镳。\r\n\r\n\r\n\r\n虽然失去了 Tadge Dryja，但 Lightning Labs 得到了 Jack Dorsey 的支持。在离开 Twitter 后，Jack Dorsey 通过他的公司 Block Inc.（原名 Square Inc.）积极推广比特币和闪电网络。\r\n\r\n\r\n\r\n2018 年，Dorsey 参与了 Lightning Labs 的种子轮融资，2022 年又参与了 Lightning Labs 1000 万美元的 A 轮融资，旨在支持其用于构建比特币 Visa 网络。可以说，Lightning Labs 的一系列开发和推进都和推特前首席执行官 Jack Dorsey 分不开关系。\r\n\r\n\r\n\r\n随后，Square 旗下 Square Crypto 项目更名为 Spiral，开发了闪电网络开发套件 LDK（Lightning Development Kit），使开发者能够将闪电网络交易集成到移动设备和销售终端。此外，Square 还推出了移动支付解决方案 Cash App，集成了闪电网络。\r\n\r\n\r\n\r\n除了 Jack Dorsey 之外，Lightning Labs 的著名投资人和机构还包括：Digital Currency Group；Robinhood；Ripple's XpringRipple 的投资部门；前全球联合创始人 Howard Morgan；高盛证券部主管 John Pfeffer（原 KKR 成员）和福布斯 30 Under 30 名人 Jill Carlson。\r\n\r\n\r\n\r\n之后有关闪电网络的协议和应用逐渐丰富起来，比如 BOLT 协议的加强版——OmniBOLT、可支持比特币闪电网络的支付平台 Cash APP 及 Strike 等等。\r\n\r\n\r\n\r\n虽然有多个团队开始了对闪电网络进行开发，但 Blockstream 和 Lightning Labs 的贡献是最不容忽视的。在闪电网络的正统性演进史中，他们的作用不容小觑。\r\n\r\n\r\n\r\n在 Blockstream 和 Lightning Labs 的推动下，那些年里，比特币的扩容方案只有两种，一种是闪电网络，一种是其他。\r\n\r\n\r\n\r\n\r\n## 闪电网络的十字路口\r\n\r\n\r\n虽然在这些年里拥有绝对的正统性，但显然的是，近一年否定闪电网络的声音也越来越多，特别是一些资深开发者。\r\n\r\n\r\n\r\n「闪电网络正在骗取比特币用户的时间、精力和金钱，长达 6 年。」Nostr 创始人 Fiatjaf 这么说道。可以说，在过去的两个月里，关于比特币闪电网络的争论愈演愈烈。近期，至少已有两位开发人员宣布退出与闪电网络相关的工作。\r\n\r\n\r\n\r\n\r\n\r\n\r\n\r\n### 开发者不断流失\r\n\r\n\r\n10 月 16 日，闪电网络安全研究员和开发人员 Antoine Riard 在一封邮件中，深入探讨了闪电网络通道所面临的资金丢失风险，这些风险主要是由于交易池的替换循环攻击问题引发的。他特别提到了一种影响闪电网络通道的交易中继干扰攻击，这在实践中是完全可能的，即使没有网络交易池拥堵也可能发生。\r\n\r\n\r\n\r\n同时 Riard 表示，自己将从现在开始停止参与闪电网络的开发，因为这种新的替换循环攻击会将闪电网络置于非常危险的境地。不过从乐观的角度来说，这种攻击有极大的复杂性，并不容易实现。\r\n\r\n\r\n\r\n\r\n\r\n\r\n\r\nAntoine Riard 宣布离开的两周后，10 月 30 日，第一个移动闪电钱包的开发者 Anton Kumaigorodski 在 Nostr 上也宣布了自己的离职。Anton Kumaigorodski 是比特币闪电钱包 (BLW) 和 Simple Bitcoin 钱包 (SBW) 的开发者，此外他还开发了 Scala IMMORTAN 库，该库允许在闪电网络客户端之上构建移动优化的应用程序。与许多闪电网络的批评者相反，他完全清楚为什么 LN 作为一种技术仍然具有挑战性。他离开的三点原因是：\r\n\r\n\r\n\r\n1. 严肃的闪电网络开发既困难又耗时，整个闪电网络协议过于复杂，而且越来越糟，在这一点上，只有极少数知名专家才能以非常缓慢的速度开发。从哲学上讲，我认为比特币作为一个协议应该有一个复杂性障碍，这样它就不会超过外行人无法理解和信任它的地步，我认为闪电网络已经通过了这个障碍。\r\n\r\n\r\n\r\n2. 经过 6 年多的斗争，闪电网络超越了一个主要由意识形态用户组成的社区，没有明显的成功或观点。我的观点是，最终闪电网络并不是整个市场对比特币的期望，除了愚蠢的支付之外，人们应该寻找其他方向，而不是过度关注闪电网络。\r\n\r\n\r\n\r\n3. 剩余的闪电网络需求主要被各种托管解决方案所吸收。在用户体验方面，一个真正的非托管闪电网络钱包总是比托管钱包更糟糕，从历史上看，我们看到大多数剩余的用户始终选择便利而不是控制。这使得开发最终用户非托管闪电网络解决方案感觉像是世界上最吃力不讨好的事情。\r\n\r\n\r\n\r\n比特币研究员和开发者 Robin Linus 在他的「BitVM」论文发表后获得了极大的关注后，补充说：「现在是时候承认我们互相过度销售闪电网络了，这或许是区块大小战争后创伤后应激障碍的一种形式。现在是时候克服它了。闪电网络对大众不起作用。」\r\n\r\n\r\n\r\nRiver 首席执行官兼首席技术官 Alexander Leishman 也指出了闪电网络中消费者自我托管的用户体验（UX）挑战，「闪电网络非常适合托管到托管转移。闪电网络给消费者的自我托管带来了巨大的用户体验挑战。」他强调了普通用户在管理其闪电网络交易时面临的困难。\r\n\r\n\r\n\r\n事实上，在闪电网络的早期开发阶段，其潜在的扩展性限制便已显而易见，这一点在闪电网络的白皮书中也有所提及，特别是关于未来所需的软分叉可能未获得支持，这被视为对闪电网络可扩展性的潜在制约因素。\r\n\r\n\r\n\r\n在这样的背景下，Blockstream 和 Lightning Labs 这两家最主要的闪电网络公司，又将作何打算呢？\r\n\r\n\r\n\r\n### 来自侧链的压力\r\n\r\n\r\n除了闪电网络之外，Blockstream 近些年工作重点是侧链产品 Liquid Network。\r\n\r\n\r\n\r\n2014 年，Adam Back、Matt Corallo 和 Luke-Jr 等人共同发表的论文《Enabling Blockchain Innovations with Pegged Sidechains》中。这篇论文首次公开提出了通过锚定侧链来推动区块链创新的理念。\r\n\r\n\r\n\r\n2015 年 10 月 12 日，Blockstream 宣布发布其 Liquid 侧链原型，该原型允许在 Liquid 侧链和比特币主链之间转移资产。2018 年 10 月 11 日，Liquid 侧链的生产就绪实现正式启动，称为 Liquid Network，旨在促进比特币主链和 Liquid 侧链之间的互操作性，以扩展比特币的功能。\r\n\r\n\r\n\r\n因 Adam Back 的论文作为雏形而诞生的侧链不止 Liquid 一个，还有 Drivechain。\r\n\r\n\r\n\r\n在 2015 年的一篇博客文章中，LayerTwoLabs 联合创始人 Paul Sztorc 进一步介绍了 Drivechain 的概念，提出了将其作为一种避免因共识分歧而导致硬分叉的方法，从而防止比特币的碎片化。Drivechain 为比特币引入了一种创新方式，允许创建和删除侧链，以及在所谓的「第二层」——侧链上发送和接收 BTC。比特币和 Drivechain 形成了父子链的关系，比特币是父级，Drivechain 是子级，因此 Drivechain 本身不发行原生代币。相反，它完全依赖于从比特币网络转移的 BTC。\r\n\r\n\r\n\r\nDrivechains 创建并依赖于盲合并挖矿概念，允许比特币区块链（父）上的矿工在不运行 Drivechain 全节点的情况下在 Drivechain（子）上挖矿，并且矿工以 BTC 支付。Paul Sztorc 在 2017 年提出了比特币改进提案 BIP 300 和 301，允许创建与比特币主网相关联但保持独立的侧链，这些侧链可以独立运行并具有不同的规则和功能。\r\n\r\n\r\n\r\nAdam Back 对 Drivechain 这种侧链形式表示赞赏：「向 Paul Sztorc 及其团队致敬，因为他们实现并验证了 Drivechain 设计。」他还认为 Drivechains 很酷，并且可以说比 Taproot 更重要或更有用。」他还提到：「我认为我们将需要一个大型 P2P 侧链，让下一个十亿用户从不可扣押的、抗审查的 #bitcoin 中受益。支持 P2P 侧链的操作码，如做 Drivechain 的 LayerTwoLabs、P2P 的 Liquidium、Rootstock。」\r\n\r\n\r\n\r\n\r\n\r\n\r\n\r\n值得一提的是，LayerTwoLabs 由耶鲁大学经济学家 Paul Sztorc 领衔创办，比特币开发者 CryptAxe（2016-至今）、Luke Dashjr（2012-至今）联袂开发。Luke Dashjr 正是前几天对比特币铭文指出批评的 Bitcoin Core 开发者，他在 8 月 22 日向 Bitcoin Core Github 代码仓库提交了 BIP300 的 PR，Bitcoin Core 社区开始审核 Drivechain 相关代码。\r\n\r\n\r\n\r\nLayerTwoLabs 目标旨在推动比特币重大升级提案 BIP300、BIP301，通过 DriveChain 来让比特币具备高度可拓展性、隐私、更好的 UX 体验，同时支持多种侧链开发，旨在把去中心化应用和区块链的其他拓展功能引入比特币生态，以实现比特币长期健康发展。LayerTwoLabs 已经完成 400 万美金天使轮融资，目前正在进行下一轮融资。\r\n\r\n\r\n\r\n前文中提到的 BitVM 的发明者 Robin Linus、Nostr 创始人 Fiatjaf 和 Anton Kumaigorodski 等名人也都在「放下」闪电网络的同时，对 Drivechain 表示了不同程度的支持。\r\n\r\n\r\n\r\n虽然获得许多比特币 OG 的支持，但距离能通过 BIP 提案，并能在上面实现大规模应用，或许还有很长的路要走。「乐观估计可能一两年，悲观估计可能要三四年。」Drivechain 开发团队 LayerTwoLabs 的投资者和亚洲区负责人 Mike Yeung 对 BlockBeats 说道。启动 Drivechain，但这无疑是一个艰巨的任务，不过 LayerTwo Labs 有一些计划和策略来加速采用 Drivechain 技术。\r\n\r\n\r\n\r\n在 Mike Yeung 看来，从技术角度来看，闪电网络存在一些安全漏洞。其次，闪电网络对矿工并无益处，实际上闪电网络与矿工的关系并不良好。至于闪电网络作为扩容工具的可能性，「我认为实际上是不可能的，因为它无法实现智能合约，能做的事情非常有限。我不认为闪电网络会完全失败，但它的前景并不乐观。」\r\n\r\n\r\n\r\n「从 2017 年开始，无数投资商，包括个人投资者、家庭办公室和风投都投资了闪电网络，他们不能让自己的投资归零。」Mike Yeung 对 BlockBeats 说道。同时一些有影响力的人物，包括 Twitter 前 CEO 和 MicroStrategy 的领导层，他们将自己的公共形象和公关策略与闪电网络的品牌紧密联系在一起。由于他们之前的公开支持和公司的性质，他们难以轻易撤回之前的言论。这导致他们不得不持续推广闪电网络的优点，尽管他们认识到其存在的局限性，且可能不是比特币扩容问题的终极解决方案。\r\n\r\n\r\n\r\n### 尝试突围\r\n\r\n\r\nBlockstream 主侧链研究，而 Taproot Assets 则专注于将 Lightning Labs 发展成一个多资产网络。\r\n\r\n\r\n\r\nTaproot Assets 是一种基于 Taproot 的 CSV 资产协议，用于在比特币区块链上发行资产。这些资产可以通过闪电网络进行即时、大量、低成本的交易。Taproot Assets 的核心是利用比特币的安全性和稳定性，以及闪电网络的速度、可扩展性和低成本。\r\n\r\n\r\n\r\n这一构想始于 2021 年，Lightning Labs 团队发现借助闪电网络，比特币在萨尔瓦多得到了国家级应用。这让 Lightning Labs CEO Elizabeth Stark 意识到，人们关注的焦点逐渐从比特币资产转向比特币的货币网络。于是团队开始构想一个多资产网络，旨在以扩大比特币和闪电的全球影响力。\r\n\r\n\r\n\r\n2022 年 9 月，Lightning Labs 发布了最初的 Taro 协议代码，并宣布获得 7000 万美元的融资。之后由于区块链初创公司 Tari Labs 指控 Taro 名称与其自有商标相似，且提供类似服务，Taro 更名为 Taproot Assets。\r\n\r\n\r\n\r\nLightning Labs 之所以要设计一个全新的协议，一方面是为了避免区块链拥堵，这也是 Taro 的设计初衷。它与闪电网络紧密集成，允许资产在 Lightning 通道中存储和转移，从而实现即时、低费用的交易。另一方面是考虑到用户对稳定币具有「压倒性」的需求以及 Lightning Labs「将美元比特币化」的目标。\r\n\r\n\r\n\r\n随着 Taproot Assets 使用比特币流动性来路由协议上发行的资产，闪电网络上对比特币的需求将更大。因此，比特币将流通美元、法定货币和介于两者之间的一切，由此实现美元比特币化。Lightning Network 的最终目标非常明确：在发布此次 Taproot Assets 后，将专注于将发展成一个多资产网络。\r\n\r\n\r\n\r\n在过去几个月的测试网开发中，早期采用者与团队不断迭代，在测试网上铸造了近 2,000 个资产，尝试稳定币、收藏品以及与 RWA 资产的潜力，并将其节点与 Universe 服务器同步，Universe 服务器是一个存储库，保存钱包初始化和下载钱包状态所需的所有信息。\r\n\r\n\r\n\r\nTaproot Assets 由 Lightning Labs 的联合创始人兼 CTO Olaoluwa Osuntokun 负责设计和开发。Olaoluwa Osuntokun 是闪电网络客户端 LND 的主要开发者之一，也是比特币客户端（BTCD）的贡献者，是少有的开发过闪电网络和比特币客户端的开发者，对比特币有着深刻的理解。\r\n\r\n\r\n\r\n### 比特币的创业精神\r\n\r\n\r\n与以太坊不同，比特币的「死板」是其正统性的根本。这种「死板」的文化强调去中心化、自由、安全和隐私，但也因此孕育出了一个公平、多元的文化和技术社区。\r\n\r\n\r\n\r\n「如果您参加过比特币和闪电网络的会议，很容易发现两者社区的差异。」\r\n\r\n\r\n\r\n这是 Antoine Riard 在自己的博客中对比特币开发者社区的评价。比特币会议（主要为 Bitcoin Core）通常聚焦于深入的技术讨论，重视安全和协议工程，参与者包括经验丰富的互联网用户、各类黑客和公民自由主义者。在经历了无数次骗局后，他们自然持怀疑态度，但知识分子的辩论依然开放而诚实。\r\n\r\n\r\n\r\n相比之下，闪电网络的人群给人的感觉不同。他们通常更年轻，更具有创业精神，讨论更多聚焦于用户体验和产品设计。会场充满活力，有许多令人眼花缭乱的闪电应用供大家体验，硅谷的影响在这里显而易见。这在闪电火炬传递的活动中也可见一斑。\r\n\r\n\r\n\r\n和 Bitcoin Core 相比，闪电网络更注重创新、实用性和社区的合作精神。这种文化上的差异反映了比特币生态系统的多样性和复杂性，同时也是其魅力和活力的源泉。\r\n\r\n\r\n\r\n在新的「比特币生态」语境下，铭文、meme 横飞，但当潮水退去时，这个生态还剩下什么？笔者认为，比特币的文化，以及更多具有创业精神的社区和团队将成为比特币网络发展的宝贵财富。\r\n\r\n\r\n\r\n作者注：本文尝试概括闪电网络的起源故事与如今的冲击，但闪电网络的历史比我已知的要丰富得多，把它们都放在一篇文章结构里需要略去许多细节，无法体现所有帮助实现这项技术的人、项目和概念。最好只把本文当成一个粗糙的总结，而不是一份详尽的历史和技术讲解。感谢每一位提供信息和其它反馈的朋友。\r\n\r\n\r\n\r\n\r\n\r\n####

**PermaDAO in Practice: From Human Governance to Fully On-chain  Governance**\r\n\r\n\r\n#### **Summary**\r\n\r\nPermaDAO is exploring the practical transition from traditional “human governance” to fully \"On-Chain Governance.\" With Bitcoin and Ethereum communities serving as examples, Decentralized Autonomous Organizations (DAOs) are flourishing with the support of blockchain technology. While DAO's have excelled in creating simple rules, navigating collaborations entailing intricate regulations remains a complex challenge. The ultimate goal for DAOs is fully on-chain governance, a realization that requires a prolonged evolutionary process. PermaDAO, recognizing this, will release the HALO governance token, progressively advancing towards a fully on-chain governance model through \"meta-governance concept.”\r\n\r\nA Decentralized Autonomous Organization (DAO) is a form of organizational structure embodied through open-source code, controlled by shareholders, and impervious to the influence of central authorities. Due to the immutable and traceable blockchain smart contracts features, DAOs have received robust technical support and have made significant strides in cryptography.\r\n\r\nThe Bitcoin and Ethereum communities represent DAOs, where consensus is formed through code, fostering community collaboration to enhance the system for common goals. DAOs have made significant strides in decentralized community governance, primarily due to the relatively simple Bitcoin and Ethereum rules. The fundamental Bitcoin rules revolve around payments, essentially involving miners providing BTC payment services. Similarly, the basic Ethereum rules entails miners to provide smart contract computing services.\r\n\r\nAdditionally, Uniswap, with its simple formula of k = x * y, offers decentralized asset swaps, representing a fundamental rule for DAOs. Built upon this formula, Uniswap serves a vast user base, liquidity providers, and arbitrageurs, creating a token exchange ecosystem that is open to all, allowing participants to join or exit at any time.\r\n\r\nIt is evident that DAOs have had a profound impact on collaborative efforts based on simple fundamental rules, yet there have yet to be notably successful cases in collaborations involving complex rules.\r\n\r\n## Dual Aspects of Governance\r\n### **Rule of man**\r\nThe traditional governance model, often referred to as the \"rule of man,\" involves individuals creating a set of rules through communication and coordination to manage production and consumption relationships. These rules are codified into laws and regulations, forming standards that can be referenced. The enforcement of laws relies on centralized violent institutions for protection.\r\n\r\nThe rule of man developed over thousands of years, has become highly mature but also intricate. Whether at the scale of a company or a nation, all the rules and laws within a system are products of human governance.\r\n\r\nA mature human governance system can handle highly complex collaborative issues, which is a capability that current DAOs have not yet fully achieved.\r\n\r\n### **Code is law**\r\n\r\nThe emergence of smart contracts has sparked a new wave of governance, making it easier to manage organizations using open-source code. Smart contracts rules are executed by machines, eliminating any margin of error, avoiding informal rules and fraud that may exist in human governance.\r\n\r\nHowever, due to this mechanism's precision, the flexibility is limited. If incorrect rules are established (often referred to as smart contract vulnerability), the losses caused by these vulnerabilities can be challenging to recover. The DAO incident on Ethereum in 2016 is an example where significant asset losses occurred due to a smart contract vulnerability. Ultimately, this led to a division within the Ethereum community. The outcome was a rollback from \"code is law\" to “rule of man\". Guided by Vitalik, the community refused to acknowledge the results created and ultimately decided to roll back the blockchain to its state before the theft occurred.\r\n\r\nAt the end of the day, the lack of flexibility restricted \"the rule of code\" to small-scale applications and scenarios with relatively simple foundational rules.\r\n\r\n## Opposing Forces?\r\n\r\nThe dual sides of governance, the “rule of man\" and “code is law” seem to have conflict and opposition. With the recurring security incidents and governance failures, does this imply that DAOs are destined to struggle with complex collaborations. Are DAOs a utopian fantasy?\r\n\r\nMaking DAOs applicable to complex collaboration rules, suitable for large-scale collaborations involving strangers, is the direction PermaDAO is looking at.\r\n\r\nIndeed, the “rule of man\" and “code is law\" are not opposing forces. Whether it's rules computed by machines or legal rules documented in books, humans remain to be the core of collaboration. DAO Practitioners don’t need to bring all actions under blockchain governance; instead, they should start with a human-based input and gradually introduce on-chain rules. The rules computed by machines aim to minimize the trust costs between individuals and reduce the consensus cost of value distribution (cutting the need for violent enforcement), rules executed by machines are more efficient and transparent, enabling human governance to achieve faster iterations and stronger execution capabilities.\r\n\r\nIn the process of PermaDAO's practice, there hasn't been an excessive pursuit of fully on-chain governance. Early on, it was driven by individual enthusiasts, gradually establishing rules, expanding the community membership, and constructing bit by bit. The following two cases might indicate an excessive reliance on on-chain governance:\r\n\r\n\r\n> **PandaDAO**. Excessive reliance on on-chain governance, token issuance, and NFT distribution, coupled with a lack of efficient decision-making and rational contributors, ultimately led to a downward spiral.\r\n\r\n>**Polkadot**. Despite establishing complex on-chain governance mechanisms upon launching, allowing all functionalities to be improved through voting, it ultimately failed to yield truly effective applications. The lesson learned is not to become excessively absorbed in on-chain governance prematurely; instead, growth should occur organically based on the needs of users and developers.\r\n\r\n\r\nThe typical manifestation of excessive on-chain governance is engaging in extensive discussions about governance and advantages even before the community has formed. This is often accomplished by creating FOMO sentiments through methods like token issuance or prematurely using NFTs as a medium for user acquisition, resulting in the unhealthy rapid growth of the community. In the end, all participants are fixed within a carefully designed behavioral pattern, unable to change anything or determine the future direction of the DAO. Embracing fully on-chain governance from the outset is not a favorable governance path. Even in mature and large ecosystems like the Bitcoin and Ethereum communities, full on-chain governance has not truly been initiated. Instead, communication, management, and iterative growth are more often facilitated through human-centric community models. The Bitcoin community grew slowly rather than being designed. It started with just a few enthusiasts running Bitcoin code on personal computers, then progressed to someone buying pizza with Bitcoin, and eventually evolved into the massive computational power we see today. The governance and development process of DAOs is both lengthy and challenging.\r\n\r\n## Meta-Governance\r\n\r\nIn stark contrast to the previously mentioned excessive on-chain governance, Meta-Governance has minimal pre-defined rules. First and foremost, there is no genuinely orchestrated set of rules by an official entity to entice more people to join and generate FOMO. Secondly, Meta-Governance places more emphasis on how the governance process is generated. It adopts a human-centric governance model, relying on contributors to create rules.\r\n\r\nThe PermaDAO theme revolves around the Arweave ecosystem, with a core philosophy of exploring large-scale collaboration amongst strangers. All rules only need to expand around these two aspects. We hope any contributor can create rules, introduce new types of work, and generate more tasks. Of course, the premise is that these rules and tasks can operate clearly, and the execution results can be recorded on the blockchain. Permanence is also a crucial foundation feature for PermaDAO. The process of everyone's contributions will ultimately be recorded on the blockchain, creating a permanent record. Your workload will forever belong to you, thanks to Arweave’s permanent storage.\r\n\r\nIn practice, through Meta-Governance, PermaDAO generates autonomous domains such as Activity Guild, Content Guild, Branding Guild, Development Guild, and more. The rules of these guilds are created spontaneously by contributors in the community. Initially, many guilds faced various issues, but as more contributors joined, there were always individuals raising questions and finding solutions.\r\n\r\nOccasionally, contributors would inquire why PermaDAO hasn't issued NFTs to attract newcomers. According to the Meta-Governance logic, the issuance of NFTs is also a rule created by contributors. There won't be corresponding rules until community members propose and promote such proposals within the community.\r\n\r\nThe governance of DAO relies on the community itself, not on any so-called official entity. Meta-governance is the process of creating rules amidst chaos, evolving from disorder to order in an automated manner.\r\n\r\n## Fully On-Chain Governance\r\n\r\nExcessive on-chain governance is not a good practice, but fully on-chain governance remains the ultimate goal that DAOs explore, it just needs a more lengthy evolutionary process to achieve it eventually. The rules of on-chain governance should not be prematurely defined. Due to the lack of flexibility in smart contract code, early definitions can lead to the model having issues and ultimately creating a death spiral to failure. After all, it hasn’t even been a decade since DAO exploration started, and there are too many issues to explore and solve. We hope to start with Meta-Governance, deriving a model of full on-chain governance from chaos, without expecting to produce a FOMO model meticulously designed by a few individuals but still flawed.\r\n\r\n### **Exploring HALO Token**\r\n\r\nPermaDAO has been using the approach of Meta-Governance in its exploration of DAO for over a year. There are over 1000 articles created and translated within the DAO, and more than 10,000 tasks of various types have been executed. These tasks include, but are not limited to, Space activities, large-scale offline events, PR campaigns, software development, content creation, content translation, financial settlements, and institutional proposals. PermaDAO's currently has 370 contributors, achieving the collaboration scale of a medium-sized enterprise through 100% online cooperation. Over 50 active contributors receive AR incentives weekly. The achievements are significant!\r\n\r\nWith the guild rules made now being mature, the DAO is poised to embark on the next phase of exploration—how to achieve fully on-chain governance! In the three stages of DAO development, pioneers delve into rule exploration when talent is scarce. After establishing rules, in the mid-term, more contributors are attracted, and a fair and transparent promotion system is instituted, fostering healthy and sustainable development. Ultimately, this leads to the exploration of fully on-chain governance.\r\n\r\nWe introduced the HALO Token for governance voting. With HALO allocation based on past workload data. All contributors will receive HALO tokens, with the quantity tied to their past workload to encourage and recognize volunteers' contributions. Initially distributed HALO will be in a locked state, granting voting and governance rights, with weight proportional to workload time. This approach respects early contributors, safeguarding their interests as they played a crucial role in the DAO's early stages when talent was scarce.\r\n\r\nThe HALO Token obtained through contributions to different guilds carries different voting characteristics. The HALO Token from that particular guild weighed ten times more than the HALO voted to other guilds. This measure is designed to safeguard the governance rights of guild professionals and prevent the rules established by a guild's founders from being easily overturned.\r\n\r\nStaked HALO can be unstaked and traded on secondary markets, but unstaking sadly means that you’ll be forfeiting your voting rights. In a permissionless DAO, new members must contribute by working or repurchasing HALO to gain voting rights. HALO purchased on the secondary market after locking won't inherit the tenfold voting weight.\r\n\r\n**Conclusion**\r\n\r\nIn the governance realm, decisions, both centralized and decentralized acknowledge the pivotal role played by individuals. In the age of information and blockchain, a unique opportunity presents itself — the creation of a platform that manifests fair and transparent visions, granting greater autonomy to individuals in designing systems. The HALO Token will serve as a powerful tool for PermaDAO to explore fully on-chain governance. Despite the risks, HALO will operate as a test token before its official launch. PermaDAO is poised to execute on-chain governance voting using blockchain technology, encompassing facets such as scrutinizing guild rule proposals, electing leaders, and rotating key positions. The efficacy of meta-governance has already manifested during PermaDAO's early stages. We firmly believe that the future will witness the exploration of highly viable solutions for complete on-chain governance, establishing the groundwork for extensive collaboration among blockchain strangers.\r\n\r\nWe extend a heartfelt welcome to individuals with expertise to join PermaDAO, contribute proposals, and engage in collaborative efforts to refine rules. Within this realm, no rules are immutable; there are only opportunities for improvement. While the current framework may seem somewhat antiquated, the forces of emergence and evolution are certain to infuse a renewed brilliance into the system.\r\n\r\n🔗 **More about PermaDAO**：[Website](www.permadao.com) | [Twitter](https://twitter.com/perma_dao) | [Telegram](https://t.me/+UEnIssIHTn0wZDc1) | [Discord](https://discord.gg/Xsp9gwT7nS) | [Medium](https://medium.com/@permadao) | [Youtube](https://www.youtube.com/@permadao)","creator":"0x51a0560c9d1336980c6b1f439676151e23f0e639","if_to_text_assets_k_v":true,"likes":0,"tags":{},"author_true":"0x51a0560c9d1336980c6b1f439676151e23f0e639","space_contract_addr":"0x0","share_holders":[]},{"id":429,"created_at":"2023-12-18T02:48:05.09579+00:00","id_on_chain":7269,"content":"\r\n# 比特币2030年必到100万美元，立此为证，支持的请加入！\r\n\r\n# Bitcoin will reach 1 Million USD before Year 2030, If you agree, please join!\r\n\r\n\r\n![](https://arweave.net/adZ6Vaj_8HZV9bLTuyepdtAem6jeUcEEnMDK_ce6rcs)","creator":"0x908a6e8add1ef3dff713c95cb6ff340a06ecdffe","if_to_text_assets_k_v":true,"likes":0,"tags":{},"author_true":"0x908a6e8add1ef3dff713c95cb6ff340a06ecdffe","space_contract_addr":"0x0","share_holders":[]},{"id":427,"created_at":"2023-12-18T02:41:04.834782+00:00","id_on_chain":7202,"content":"*******比特币*******\r\n是第一个加密电子货币，其特色是使用密码学来控制货币的制造和管理，而非依赖特定的中央机构[1]。然而，比特币背后的科技和概念并非均为新创；其推测的幕后发明人中本聪结合了许多来自数位朋克社群的既有想法，创造了比特币。\r\n比特币创建前\r\n在比特币发行之前，世界上已有存在种不同的“ecash”技术和产品，最早的起源来自大卫·乔姆[2]和史戴分·布蓝兹所提出之以发行者为主的ecash协议。接着许多以ecash协议为基础的数位货币等产品开始出现，其中以亚当·贝克的“hashcash”、戴维(Wei Dai)[3]的“b-money”、尼克·萨博的“bit-gold”，以及哈尔·芬尼在“hashcash”技术上发展的“RPOW”等。\r\n当戴维和萨博正分别各自规划“b-money”和“bit-gold”时[4][5]，分尼实作出了“RPOW”：一种基于IBM可信平台模块硬件和远端证明（remote attestation）的新形态“hashcash”。“RPOW”的特色在于可重复使用，且虽然控管权集中，但发行者没有通胀压力。\r\n在萨博最初的“bit-gold”构想中，包括了利用以市场为基础的机制来控制通胀。此外，包括拜占庭将军问题在内，萨博也钻研了其他的分散式资产登记授权方式。\r\n\r\n创建期\r\n\r\n2008年11月，一份署名中本聪的论文被发表在网络上，其标题为《比特币：对等网络电子现金系统》（Bitcoin: A Peer-to-Peer Electronic Cash System）。论文中详细描述了如何使用对等网络来创造一种“不需依赖信任的电子交易系统”[注 2][6][7][8][9]。2009年1月比特币网络上线，推出了第一个开源的比特币客户端软件，中本聪使用该软件对第一个比特币“区块”（block，又称为创始区块，genesis block）进行“采矿”（mining），并获得了第一批的50个比特币[7][10][11][12]。最初比特币交易的价值由“bitcointalk”论坛上的使用者彼此协商，其中包括以10,000比特币兑换一整个披萨[7]。\r\n在2010年8月6日，比特币协议被发现重大漏洞，交易在登录到记录或“区块链”（block chain）之前并没有经过完整认证，让使用者可以绕过比特币的经济限制设定，并制造出无上限的比特币[13][14]。8月15日，这个漏洞被恶意利用；一笔转账交易过程中产生了1840亿比特币，并分别转送到比特币网络上的两个地址。在不到一小时内，这笔异常交易就被发现，并在漏洞修复后被从交易记录上删除，整个网络也更新为新版的比特币协议[15][16]。截至2014年2月，这是比特币历史上唯一发现并被利用的重大安全漏洞[13][14]。\r\n成长期\r\n2011年6月起，维基解密[17]和其他组织开始接受以比特币支付的捐献。电子前哨基金会（EFF）在开始接受比特币后不久又暂停交易，该基金会指出新的货币系统缺乏法律上可供参考的前例，并表示他们“通常不会为任何形式的产品或服务背书[18]。”电子前哨基金会在2013年5月7日宣布重新开始接受比特币[19]。2011年12月24日，“BitBills”公司的道格拉斯·费格森（Douglas Feigelson）向美国专利及商标局递交了一份专利申请，其主题为“创造和使用数位货币”。这项申请在2013年6月被以现有技术为由驳回。[20][21]\r\n价格与汇率历史\r\n在可能造成欧洲主权债务危机的诸多原因中，金融犯罪打击小组（FinCEN）所发表的一份声明让比特币的法律地位和媒体关注度明显提升[22][23][24][25]。截至2023年9月，比特币最高的价格是2021年11月的68,991美元[26]。\r\n比特币兑美元价格历史\r\n日期\tBTC：USD\t备注\r\n2010年\t初始 400 : 1\t在比特币论坛“bitcointalk”上，用户群自发交易中，产生了第一个比特币公允汇率。该交易是一名用户发送10,000比特币，购买了两块价值25美元的披萨饼。[27][28]比特币公开交易开始时，其汇率主要参考Mtgox交易所内比特币与美元的成交汇率。[29]\r\n2011年\t最低 100 : 1\t为了打破全球权威集团的金融封锁，维基解密刚宣布接受比特币捐助，全球最大的交易网站Mt.

A Peer-to-Peer Electronic Cash System\r\nSatoshi Nakamoto\r\nsatoshin@gmx.com\r\nwww.bitcoin.org\r\nAbstract. A purely peer-to-peer version of electronic cash would allow online\r\npayments to be sent directly from one party to another without going through a\r\nfinancial institution. Digital signatures provide part of the solution, but the main\r\nbenefits are lost if a trusted third party is still required to prevent double-spending.\r\nWe propose a solution to the double-spending problem using a peer-to-peer network.\r\nThe network timestamps transactions by hashing them into an ongoing chain of\r\nhash-based proof-of-work, forming a record that cannot be changed without redoing\r\nthe proof-of-work. The longest chain not only serves as proof of the sequence of\r\nevents witnessed, but proof that it came from the largest pool of CPU power. As\r\nlong as a majority of CPU power is controlled by nodes that are not cooperating to\r\nattack the network, they'll generate the longest chain and outpace attackers. The\r\nnetwork itself requires minimal structure. Messages are broadcast on a best effort\r\nbasis, and nodes can leave and rejoin the network at will, accepting the longest\r\nproof-of-work chain as proof of what happened while they were gone.\r\n\r\n1. Introduction\r\nCommerce on the Internet has come to rely almost exclusively on financial institutions serving as\r\ntrusted third parties to process electronic payments. While the system works well enough for\r\nmost transactions, it still suffers from the inherent weaknesses of the trust based model.\r\nCompletely non-reversible transactions are not really possible, since financial institutions cannot\r\navoid mediating disputes. The cost of mediation increases transaction costs, limiting the\r\nminimum practical transaction size and cutting off the possibility for small casual transactions,\r\nand there is a broader cost in the loss of ability to make non-reversible payments for non-\r\nreversible services. With the possibility of reversal, the need for trust spreads. Merchants must\r\nbe wary of their customers, hassling them for more information than they would otherwise need.\r\nA certain percentage of fraud is accepted as unavoidable. These costs and payment uncertainties\r\ncan be avoided in person by using physical currency, but no mechanism exists to make payments\r\nover a communications channel without a trusted party.\r\nWhat is needed is an electronic payment system based on cryptographic proof instead of trust,\r\nallowing any two willing parties to transact directly with each other without the need for a trusted\r\nthird party. Transactions that are computationally impractical to reverse would protect sellers\r\nfrom fraud, and routine escrow mechanisms could easily be implemented to protect buyers. In\r\nthis paper, we propose a solution to the double-spending problem using a peer-to-peer distributed\r\ntimestamp server to generate computational proof of the chronological order of transactions. The\r\nsystem is secure as long as honest nodes collectively control more CPU power than any\r\ncooperating group of attacker nodes.\r\n \r\n2. Transactions\r\nWe define an electronic coin as a chain of digital signatures. Each owner transfers the coin to the\r\nnext by digitally signing a hash of the previous transaction and the public key of the next owner\r\nand adding these to the end of the coin. A payee can verify the signatures to verify the chain of\r\nownership.\r\nTransaction\r\nTransaction\r\nTransaction\r\nOwner 1's\r\nPublic Key\r\nOwner 2's\r\nPublic Key\r\nOwner 3's\r\nPublic Key\r\nHash\r\nHash\r\nHash\r\nOwner 0's\r\nSignature\r\nOwner 1's\r\nSignature\r\nOwner 2's\r\nSignature\r\nOwner 1's\r\nOwner 2's\r\nOwner 3's\r\nPrivate Key\r\nPrivate Key\r\nPrivate Key\r\nThe problem of course is the payee can't verify that one of the owners did not double-spend\r\nthe coin. A common solution is to introduce a trusted central authority, or mint, that checks every\r\ntransaction for double spending. After each transaction, the coin must be returned to the mint to\r\nissue a new coin, and only coins issued directly from the mint are trusted not to be double-spent.\r\nThe problem with this solution is that the fate of the entire money system depends on the\r\ncompany running the mint, with every transaction having to go through them, just like a bank.\r\nWe need a way for the payee to know that the previous owners did not sign any earlier\r\ntransactions. For our purposes, the earliest transaction is the one that counts, so we don't care\r\nabout later attempts to double-spend. The only way to confirm the absence of a transaction is to\r\nbe aware of all transactions. In the mint based model, the mint was aware of all transactions and\r\ndecided which arrived first. To accomplish this without a trusted party, transactions must be\r\npublicly announced [1], and we need a system for participants to agree on a single history of the\r\norder in which they were received. The payee needs proof that at the time of each transaction, the\r\nmajority of nodes agreed it was the first received.\r\n3. Timestamp Server\r\nThe solution we propose begins with a timestamp server. A timestamp server works by taking a\r\nhash of a block of items to be timestamped and widely publishing the hash, such as in a\r\nnewspaper or Usenet post [2-5]. The timestamp proves that the data must have existed at the\r\ntime, obviously, in order to get into the hash. Each timestamp includes the previous timestamp in\r\nits hash, forming a chain, with each additional timestamp reinforcing the ones before it.\r\nHash\r\nHash\r\nBlock\r\nItem\r\nBlock\r\nItem\r\nItem\r\n...\r\nItem\r\n...\r\n2\r\n\r\n \r\n4. Proof-of-Work\r\nTo implement a distributed timestamp server on a peer-to-peer basis, we will need to use a proof-\r\nof-work system similar to Adam Back's Hashcash [6], rather than newspaper or Usenet posts.\r\nThe proof-of-work involves scanning for a value that when hashed, such as with SHA-256, the\r\nhash begins with a number of zero bits. The average work required is exponential in the number\r\nof zero bits required and can be verified by executing a single hash.\r\nFor our timestamp network, we implement the proof-of-work by incrementing a nonce in the\r\nblock until a value is found that gives the block's hash the required zero bits. Once the CPU\r\neffort has been expended to make it satisfy the proof-of-work, the block cannot be changed\r\nwithout redoing the work. As later blocks are chained after it, the work to change the block\r\nwould include redoing all the blocks after it.\r\nBlock\r\nPrev Hash\r\nTx Tx\r\nBlock\r\nPrev Hash\r\nTx Tx\r\nNonce\r\n...\r\nNonce\r\n...\r\nThe proof-of-work also solves the problem of determining representation in majority decision\r\nmaking. If the majority were based on one-IP-address-one-vote, it could be subverted by anyone\r\nable to allocate many IPs. Proof-of-work is essentially one-CPU-one-vote. The majority\r\ndecision is represented by the longest chain, which has the greatest proof-of-work effort invested\r\nin it. If a majority of CPU power is controlled by honest nodes, the honest chain will grow the\r\nfastest and outpace any competing chains. To modify a past block, an attacker would have to\r\nredo the proof-of-work of the block and all blocks after it and then catch up with and surpass the\r\nwork of the honest nodes. We will show later that the probability of a slower attacker catching up\r\ndiminishes exponentially as subsequent blocks are added.\r\nTo compensate for increasing hardware speed and varying interest in running nodes over time,\r\nthe proof-of-work difficulty is determined by a moving average targeting an average number of\r\nblocks per hour. If they're generated too fast, the difficulty increases.\r\n5. Network\r\nThe steps to run the network are as follows:\r\n1) New transactions are broadcast to all nodes.\r\n2) Each node collects new transactions into a block.\r\n3) Each node works on finding a difficult proof-of-work for its block.\r\n4) When a node finds a proof-of-work, it broadcasts the block to all nodes.\r\n5) Nodes accept the block only if all transactions in it are valid and not already spent.\r\n6) Nodes express their acceptance of the block by working on creating the next block in the\r\nchain, using the hash of the accepted block as the previous hash.\r\nNodes always consider the longest chain to be the correct one and will keep working on\r\nextending it. If two nodes broadcast different versions of the next block simultaneously, some\r\nnodes may receive one or the other first. In that case, they work on the first one they received,\r\nbut save the other branch in case it becomes longer. The tie will be broken when the next proof-\r\nof-work is found and one branch becomes longer; the nodes that were working on the other\r\nbranch will then switch to the longer one.\r\n3\r\n\r\n \r\nNew transaction broadcasts do not necessarily need to reach all nodes. As long as they reach\r\nmany nodes, they will get into a block before long. Block broadcasts are also tolerant of dropped\r\nmessages. If a node does not receive a block, it will request it when it receives the next block and\r\nrealizes it missed one.\r\n6. Incentive\r\nBy convention, the first transaction in a block is a special transaction that starts a new coin owned\r\nby the creator of the block. This adds an incentive for nodes to support the network, and provides\r\na way to initially distribute coins into circulation, since there is no central authority to issue them.\r\nThe steady addition of a constant of amount of new coins is analogous to gold miners expending\r\nresources to add gold to circulation. In our case, it is CPU time and electricity that is expended.\r\nThe incentive can also be funded with transaction fees. If the output value of a transaction is\r\nless than its input value, the difference is a transaction fee that is added to the incentive value of\r\nthe block containing the transaction. Once a predetermined number of coins have entered\r\ncirculation, the incentive can transition entirely to transaction fees and be completely inflation\r\nfree.\r\nThe incentive may help encourage nodes to stay honest. If a greedy attacker is able to\r\nassemble more CPU power than all the honest nodes, he would have to choose between using it\r\nto defraud people by stealing back his payments, or using it to generate new coins. He ought to\r\nfind it more profitable to play by the rules, such rules that favour him with more new coins than\r\neveryone else combined, than to undermine the system and the validity of his own wealth.\r\n7. Reclaiming Disk Space\r\nOnce the latest transaction in a coin is buried under enough blocks, the spent transactions before\r\nit can be discarded to save disk space. To facilitate this without breaking the block's hash,\r\ntransactions are hashed in a Merkle Tree [7][2][5], with only the root included in the block's hash.\r\nOld blocks can then be compacted by stubbing off branches of the tree. The interior hashes do\r\nnot need to be stored.\r\nBlock\r\nBlock\r\nBlock Header (Block Hash)\r\nBlock Header (Block Hash)\r\nPrev Hash\r\nRoot Hash\r\nNonce\r\nPrev Hash\r\nRoot Hash\r\nNonce\r\nHash01\r\nHash23\r\nHash01\r\nHash23\r\nHash0\r\nHash1\r\nTx1\r\nHash2\r\nHash3\r\nTx3\r\nHash2\r\nHash3\r\nTx0\r\nTx2\r\nTx3\r\nAfter Pruning Tx0-2 from the Block\r\nTransactions Hashed in a Merkle Tree\r\nA block header with no transactions would be about 80 bytes. If we suppose blocks are\r\ngenerated every 10 minutes, 80 bytes * 6 * 24 * 365 = 4.2MB per year. With computer systems\r\ntypically selling with 2GB of RAM as of 2008, and Moore's Law predicting current growth of\r\n1.2GB per year, storage should not be a problem even if the block headers must be kept in\r\nmemory.\r\n4\r\n\r\n \r\n8. Simplified Payment Verification\r\nIt is possible to verify payments without running a full network node. A user only needs to keep\r\na copy of the block headers of the longest proof-of-work chain, which he can get by querying\r\nnetwork nodes until he's convinced he has the longest chain, and obtain the Merkle branch\r\nlinking the transaction to the block it's timestamped in. He can't check the transaction for\r\nhimself, but by linking it to a place in the chain, he can see that a network node has accepted it,\r\nand blocks added after it further confirm the network has accepted it.\r\nLongest Proof-of-Work Chain\r\nBlock Header\r\nPrev Hash\r\nBlock Header\r\nPrev Hash\r\nBlock Header\r\nPrev Hash\r\nNonce\r\nNonce\r\nNonce\r\nMerkle Root\r\nMerkle Root\r\nMerkle Root\r\nHash01\r\nHash23\r\nMerkle Branch for Tx3\r\nHash3\r\nHash2\r\nTx3\r\nAs such, the verification is reliable as long as honest nodes control the network, but is more\r\nvulnerable if the network is overpowered by an attacker. While network nodes can verify\r\ntransactions for themselves, the simplified method can be fooled by an attacker's fabricated\r\ntransactions for as long as the attacker can continue to overpower the network. One strategy to\r\nprotect against this would be to accept alerts from network nodes when they detect an invalid\r\nblock, prompting the user's software to download the full block and alerted transactions to\r\nconfirm the inconsistency. Businesses that receive frequent payments will probably still want to\r\nrun their own nodes for more independent security and quicker verification.\r\n9. Combining and Splitting Value\r\nAlthough it would be possible to handle coins individually, it would be unwieldy to make a\r\nseparate transaction for every cent in a transfer. To allow value to be split and combined,\r\ntransactions contain multiple inputs and outputs. Normally there will be either a single input\r\nfrom a larger previous transaction or multiple inputs combining smaller amounts, and at most two\r\noutputs: one for the payment, and one returning the change, if any, back to the sender.\r\nTransaction\r\nIn\r\nIn\r\n...\r\nOut\r\n...\r\nIt should be noted that fan-out, where a transaction depends on several transactions, and those\r\ntransactions depend on many more, is not a problem here. There is never the need to extract a\r\ncomplete standalone copy of a transaction's history.\r\n5\r\n\r\n \r\n10. Privacy\r\nThe traditional banking model achieves a level of privacy by limiting access to information to the\r\nparties involved and the trusted third party. The necessity to announce all transactions publicly\r\nprecludes this method, but privacy can still be maintained by breaking the flow of information in\r\nanother place: by keeping public keys anonymous. The public can see that someone is sending\r\nan amount to someone else, but without information linking the transaction to anyone. This is\r\nsimilar to the level of information released by stock exchanges, where the time and size of\r\nindividual trades, the \"tape\", is made public, but without telling who the parties were.\r\nTraditional Privacy Model\r\nTrusted\r\nThird Party\r\nIdentities\r\nTransactions\r\nCounterparty\r\nPublic\r\nNew Privacy Model\r\nIdentities\r\nTransactions\r\nPublic\r\nAs an additional firewall, a new key pair should be used for each transaction to keep them\r\nfrom being linked to a common owner. Some linking is still unavoidable with multi-input\r\ntransactions, which necessarily reveal that their inputs were owned by the same owner. The risk\r\nis that if the owner of a key is revealed, linking could reveal other transactions that belonged to\r\nthe same owner.\r\n11. Calculations\r\nWe consider the scenario of an attacker trying to generate an alternate chain faster than the honest\r\nchain. Even if this is accomplished, it does not throw the system open to arbitrary changes, such\r\nas creating value out of thin air or taking money that never belonged to the attacker. Nodes are\r\nnot going to accept an invalid transaction as payment, and honest nodes will never accept a block\r\ncontaining them. An attacker can only try to change one of his own transactions to take back\r\nmoney he recently spent.\r\nThe race between the honest chain and an attacker chain can be characterized as a Binomial\r\nRandom Walk. The success event is the honest chain being extended by one block, increasing its\r\nlead by +1, and the failure event is the attacker's chain being extended by one block, reducing the\r\ngap by -1.\r\nThe probability of an attacker catching up from a given deficit is analogous to a Gambler's\r\nRuin problem. Suppose a gambler with unlimited credit starts at a deficit and plays potentially an\r\ninfinite number of trials to try to reach breakeven. We can calculate the probability he ever\r\nreaches breakeven, or that an attacker ever catches up with the honest chain, as follows [8]:\r\np = probability an honest node finds the next block\r\nq = probability the attacker finds the next block\r\nqz = probability the attacker will ever catch up from z blocks behind\r\n1\r\nif p≤q\r\n{\r\nqz=\r\n}\r\nq/ pz if pq\r\n6\r\n\r\n \r\nGiven our assumption that p > q, the probability drops exponentially as the number of blocks the\r\nattacker has to catch up with increases. With the odds against him, if he doesn't make a lucky\r\nlunge forward early on, his chances become vanishingly small as he falls further behind.\r\nWe now consider how long the recipient of a new transaction needs to wait before being\r\nsufficiently certain the sender can't change the transaction. We assume the sender is an attacker\r\nwho wants to make the recipient believe he paid him for a while, then switch it to pay back to\r\nhimself after some time has passed. The receiver will be alerted when that happens, but the\r\nsender hopes it will be too late.\r\nThe receiver generates a new key pair and gives the public key to the sender shortly before\r\nsigning. This prevents the sender from preparing a chain of blocks ahead of time by working on\r\nit continuously until he is lucky enough to get far enough ahead, then executing the transaction at\r\nthat moment. Once the transaction is sent, the dishonest sender starts working in secret on a\r\nparallel chain containing an alternate version of his transaction.\r\nThe recipient waits until the transaction has been added to a block and z blocks have been\r\nlinked after it. He doesn't know the exact amount of progress the attacker has made, but\r\nassuming the honest blocks took the average expected time per block, the attacker's potential\r\nprogress will be a Poisson distribution with expected value:\r\nq\r\np\r\nz\r\nTo get the probability the attacker could still catch up now, we multiply the Poisson density for\r\neach amount of progress he could have made by the probability he could catch up from that point:\r\n∞\r\nk e− q/ p z−k if k≤ z\r\n⋅{\r\n}\r\nif k z\r\n∑\r\nk!\r\n1\r\nk=0\r\nRearranging to avoid summing the infinite tail of the distribution...\r\nz\r\nk e\r\n−\r\n1−∑\r\n1−q/ p z−k\r\n\r\nk!\r\nk=0\r\nConverting to C code...\r\n#include <math.h>\r\ndouble AttackerSuccessProbability(double q, int z)\r\n{\r\n    double p = 1.0 - q;\r\n    double lambda = z * (q / p);\r\n    double sum = 1.0;\r\n    int i, k;\r\n    for (k = 0; k <= z; k++)\r\n    {\r\n        double poisson = exp(-lambda);\r\n        for (i = 1; i <= k; i++)\r\n            poisson *= lambda / i;\r\n        sum -= poisson * (1 - pow(q / p, z - k));\r\n    }\r\n    return sum;\r\n}\r\n7\r\n\r\n \r\nRunning some results, we can see the probability drop off exponentially with z.\r\nq=0.1\r\nz=0    P=1.0000000\r\nz=1    P=0.2045873\r\nz=2    P=0.0509779\r\nz=3    P=0.0131722\r\nz=4    P=0.0034552\r\nz=5    P=0.0009137\r\nz=6    P=0.0002428\r\nz=7    P=0.0000647\r\nz=8    P=0.0000173\r\nz=9    P=0.0000046\r\nz=10   P=0.0000012\r\nq=0.3\r\nz=0    P=1.0000000\r\nz=5    P=0.1773523\r\nz=10   P=0.0416605\r\nz=15   P=0.0101008\r\nz=20   P=0.0024804\r\nz=25   P=0.0006132\r\nz=30   P=0.0001522\r\nz=35   P=0.0000379\r\nz=40   P=0.0000095\r\nz=45   P=0.0000024\r\nz=50   P=0.0000006\r\nSolving for P less than 0.1%...\r\nP < 0.001\r\nq=0.10   z=5\r\nq=0.15   z=8\r\nq=0.20   z=11\r\nq=0.25   z=15\r\nq=0.30   z=24\r\nq=0.35   z=41\r\nq=0.40   z=89\r\nq=0.45   z=340\r\n12. Conclusion\r\nWe have proposed a system for electronic transactions without relying on trust. We started with\r\nthe usual framework of coins made from digital signatures, which provides strong control of\r\nownership, but is incomplete without a way to prevent double-spending. To solve this, we\r\nproposed a peer-to-peer network using proof-of-work to record a public history of transactions\r\nthat quickly becomes computationally impractical for an attacker to change if honest nodes\r\ncontrol a majority of CPU power. The network is robust in its unstructured simplicity. Nodes\r\nwork all at once with little coordination. They do not need to be identified, since messages are\r\nnot routed to any particular place and only need to be delivered on a best effort basis. Nodes can\r\nleave and rejoin the network at will, accepting the proof-of-work chain as proof of what\r\nhappened while they were gone. They vote with their CPU power, expressing their acceptance of\r\nvalid blocks by working on extending them and rejecting invalid blocks by refusing to work on\r\nthem. Any needed rules and incentives can be enforced with this consensus mechanism.\r\n8\r\n\r\n\r\n \r\nReferences\r\n[1] W. Dai, \"b-money,\" http://www.weidai.com/bmoney.txt, 1998.\r\n[2] H.

Congratulations to all participants!\r\n\r\nFriends who haven't had time to participate, don't feel regretful. People tend to overestimate the short-term value of something and underestimate the long-term value.\r\n\r\nToday, US$1 billion for an asset with “no fundamentals” may be too expensive, and the secondary market is bound to be shaken up.\r\n\r\nBut looking back five years later, one billion US dollars may be just a starting point, and short-term surges and plummets are just small waves in the long history.\r\n\r\nUnisat's empowerment of $sats is a good thing, and Binance's listing of $sats is also a good thing, but it is these benefits that paralyze most people and make them ignore the real biggest narrative——\r\n\r\nUsing Bitcoin to surpass Bitcoin is the most exciting story\r\n\r\nIn 2009, when Satoshi Nakamoto deployed the genesis block on a server in Helsinki, Bitcoin was nothing more than a meme with no future in sight.\r\n\r\n14 years of long journey, countless fuds, finally today, I am recognized by the mainstream\r\n\r\nThis is a revolutionary road for super-sovereign currency. We praise the success of Bitcoin, but we can’t help but sigh that while it has achieved success for a group of people, it has also restrained a group of people. It has achieved the redistribution of wealth, but it has also Let a group of upstarts ascend to the altar, which is out of reach\r\n\r\nCountless people have asked themselves, if I had been born 10 years ago, maybe I would have had the opportunity to become a Marquis of Wanbi?\r\n\r\nIf I had been exposed to Bitcoin a few years earlier, maybe I would have been a part of the legendary wealth?\r\n\r\nPrinces, generals and prime ministers would rather have the seed\r\n\r\nEmotion is the most powerful force in the world. It will coerce tens of millions of users to flood into the market and join the wave.\r\n\r\nThere will always be people who believe that $sats is Bitcoin growing on Bitcoin\r\n\r\nThere will always be people who believe that $sats is an opportunity for young people who have missed out on Bitcoin in the past decade or so to open a new map, an opportunity to re-take the Long March, and an opportunity to \"replace them with others.\"\r\n\r\nEverything is about money except money, money is about story\r\n\r\nPutting aside the asset level, as the first batch of entrepreneurs in Inscription Ecosystem, we also want to share some practitioners’ perspectives.\r\n\r\nIn early September, our team participated in the first ordinals summit\r\n\r\nAt that time, Singapore was crowded, and well-dressed attendees gathered at the yacht parties of various tens of billions of king projects to drink and mingle.\r\n\r\nThe ordinals summit site only had a simple conference room and a room full of developers, which was extremely cold in comparison.\r\n\r\nSome people today think that the craze for inscriptions comes naturally, but only those who have experienced it know how painful it is to have no one care about the process.\r\n\r\nCompared with today’s spaces where there are often thousands of people, the rooms where Bitcoin ecology is discussed in June and July often only have a few people chatting.\r\n\r\nAt that time, $ordi had just retraced 90% from its high point, and $sats was considered to be unfinished for a long time.\r\n\r\nA start-up team wants to get support from the capital market. If they talk to the top VCs, they can only get a polite answer: \"Okay, let's study it\", and there is no further article.\r\n\r\nIt was really miserable at that time. I wanted money but no money, and I wanted traffic but no traffic. What should I do? Tighten our belts and pay for construction out of our own pockets\r\n\r\nIt is moments like this that eliminate speculators and leave pure builders behind. Everyone exchanges technology, explores directions, and enjoys the paradigm shift promoted by unowned tokens.\r\n\r\nLet's all survive the bleak market situation in the middle of the year, survive the Bitcoin plunge in September, survive the rejection of many mainstream VCs, survive the market's prejudice and criticism, and usher in the dawn of prosperity.\r\n\r\nIn this mass carnival, mainstream institutions and high-profile industry OGs are speechless.\r\n\r\nIn the past few years, they have long been accustomed to taking advantage of the industry's ecological niche to obtain asymmetric information, control the pricing power of assets, and reap deterministic returns.\r\n\r\nThe birth of inscriptions and the popularity of ownerless tokens express a kind of confrontation:\r\n\r\nThis industry does not welcome sitting back and reaping the benefits, nor does it welcome vested interests.\r\n\r\nRather than carrying the sedan chair for the Heavenly Death project, which is often valued at tens of billions, New Money is more willing to open new poker tables and create new narratives\r\n\r\nNo matter how long you have been in the industry or how much you are worth, if you don’t make progress, you will be replaced.\r\n\r\nInstitutional bosses with billions of dollars, veteran miners with tens of thousands of Bitcoins, and industry elites who come and go from high-end office buildings are no longer enviable.\r\n\r\nThe migrant workers who conduct in-depth market research, the influencers who run Space for 8 hours a day, the volunteers who do dirty work for the community, every ordinary participant is the unsung hero who truly drives this ecological change.\r\n\r\nWhoever will shake the world with his voice will be silent for a long time; whoever will sparkle lightning will be wandering like a cloud for a long time.\r\n\r\nFriends who have participated in Ethereum nft must still remember Azuki’s rug.\r\n\r\nAn obvious problem is that if money comes too easily and project developers are not punished for failing, then similar rugs will happen again and again, and human nature cannot stand the test.\r\n\r\nInscription Ecosystem provides a new way of solving problems: assets are no longer built around the project party, but one or more project parties jointly build around an asset.\r\n\r\nTake Bitmap as an example. The founder proposed an idea, but the real builders were a group of developers who had nothing to do with the founder. They recognized the concept and bought Bitmap with real money and invested in development.\r\n\r\nThis is very difficult in the initial stage. You have to spend money to support the team and buy assets. If the project is not completed, you will lose your wife and lose your troops. The speculators will shake their heads after hearing this, and the sick people will curse after hearing this.\r\n\r\nHowever, the teams that recognize this concept and participate in it are all selected strong people. Their action of buying and building unowned assets is not only the best PR, but also a letter of investment written to the market:\r\n\r\nWe don’t have free chips. Considering the team operating costs, our holding costs are even higher than those of retail investors. We work for retail investors. It is impossible to run away. Only by building a good community together can we achieve asset appreciation. come reward\r\n\r\nWe can’t help but wonder, what if there are more than one or two teams involved in the construction of an asset, but a group of them?\r\n\r\nWhat if every subdivided track in the Inscription Ecosystem could have an unowned asset that gathered the empowerment of many project parties?\r\n\r\nThen these unowned assets are no longer the spokesperson of any project or team, but have become a new narrative and a value gathering place for each segmented track.\r\n\r\nWe no longer have to worry about rugs like Azuki and others, we don’t have to worry about the project party secretly unlocking and smashing the market, and we don’t have to worry about the sickle making profits and running away leaving a pile of chicken feathers.\r\n\r\nIf one project party falls, thousands of project parties will stand up.\r\n\r\nOnly when assets are no longer tied up in any single project can they truly have antifragility.\r\n\r\nOn September 15th, when we sent out our first official push, we gave away 40 billion sats in a lottery. Later activities gave away 100 billion, costing 500 knives. Today it is worth 50,000 knives, which is exactly 100 times.\r\n\r\nPast experience has proven that we have the vision to discover 100-fold targets. Next, we want to start the creation of the next 100-fold target.\r\n\r\nWe would like to invite everyone who reads this letter to participate in this community donation plan of \"Looking for the Next 100x Coin\":\r\n\r\nWe will open the community donation address: bc1qfsmktsdxfnjcjck2dkxfkes6ly0wz8llkp62uk\r\n\r\nFrom now on, all product users, investors, practitioners, and builders are welcome to donate Bitcoin chain assets to this address, regardless of type or quantity.

Digital signatures provide part of the solution, but the main\r\nbenefits are lost if a trusted third party is still required to prevent double-spending.\r\nWe propose a solution to the double-spending problem using a peer-to-peer network.\r\nThe network timestamps transactions by hashing them into an ongoing chain of\r\nhash-based proof-of-work, forming a record that cannot be changed without redoing\r\nthe proof-of-work. The longest chain not only serves as proof of the sequence of\r\nevents witnessed, but proof that it came from the largest pool of CPU power. As\r\nlong as a majority of CPU power is controlled by nodes that are not cooperating to\r\nattack the network, they'll generate the longest chain and outpace attackers. The\r\nnetwork itself requires minimal structure. Messages are broadcast on a best effort\r\nbasis, and nodes can leave and rejoin the network at will, accepting the longest\r\nproof-of-work chain as proof of what happened while they were gone.\r\n1. Introduction\r\nCommerce on the Internet has come to rely almost exclusively on financial institutions serving as\r\ntrusted third parties to process electronic payments. While the system works well enough for\r\nmost transactions, it still suffers from the inherent weaknesses of the trust based model.\r\nCompletely non-reversible transactions are not really possible, since financial institutions cannot\r\navoid mediating disputes. The cost of mediation increases transaction costs, limiting the\r\nminimum practical transaction size and cutting off the possibility for small casual transactions,\r\nand there is a broader cost in the loss of ability to make non-reversible payments for nonreversible services. With the possibility of reversal, the need for trust spreads. Merchants must\r\nbe wary of their customers, hassling them for more information than they would otherwise need.\r\nA certain percentage of fraud is accepted as unavoidable. These costs and payment uncertainties\r\ncan be avoided in person by using physical currency, but no mechanism exists to make payments\r\nover a communications channel without a trusted party.\r\nWhat is needed is an electronic payment system based on cryptographic proof instead of trust,\r\nallowing any two willing parties to transact directly with each other without the need for a trusted\r\nthird party. Transactions that are computationally impractical to reverse would protect sellers\r\nfrom fraud, and routine escrow mechanisms could easily be implemented to protect buyers. In\r\nthis paper, we propose a solution to the double-spending problem using a peer-to-peer distributed\r\ntimestamp server to generate computational proof of the chronological order of transactions. The\r\nsystem is secure as long as honest nodes collectively control more CPU power than any\r\ncooperating group of attacker nodes.\r\n1\r\n2. Transactions\r\nWe define an electronic coin as a chain of digital signatures. Each owner transfers the coin to the\r\nnext by digitally signing a hash of the previous transaction and the public key of the next owner\r\nand adding these to the end of the coin. A payee can verify the signatures to verify the chain of\r\nownership.\r\nThe problem of course is the payee can't verify that one of the owners did not double-spend\r\nthe coin. A common solution is to introduce a trusted central authority, or mint, that checks every\r\ntransaction for double spending. After each transaction, the coin must be returned to the mint to\r\nissue a new coin, and only coins issued directly from the mint are trusted not to be double-spent.\r\nThe problem with this solution is that the fate of the entire money system depends on the\r\ncompany running the mint, with every transaction having to go through them, just like a bank.\r\nWe need a way for the payee to know that the previous owners did not sign any earlier\r\ntransactions. For our purposes, the earliest transaction is the one that counts, so we don't care\r\nabout later attempts to double-spend. The only way to confirm the absence of a transaction is to\r\nbe aware of all transactions. In the mint based model, the mint was aware of all transactions and\r\ndecided which arrived first. To accomplish this without a trusted party, transactions must be\r\npublicly announced [1], and we need a system for participants to agree on a single history of the\r\norder in which they were received. The payee needs proof that at the time of each transaction, the\r\nmajority of nodes agreed it was the first received.\r\n3. Timestamp Server\r\nThe solution we propose begins with a timestamp server. A timestamp server works by taking a\r\nhash of a block of items to be timestamped and widely publishing the hash, such as in a\r\nnewspaper or Usenet post [2-5]. The timestamp proves that the data must have existed at the\r\ntime, obviously, in order to get into the hash. Each timestamp includes the previous timestamp in\r\nits hash, forming a chain, with each additional timestamp reinforcing the ones before it.\r\n2\r\nBlock\r\nItem Item ...\r\nHash\r\nBlock\r\nItem Item ...\r\nHash\r\nTransaction\r\nOwner 1's\r\nPublic Key\r\nOwner 0's\r\nSignature\r\nHash\r\nTransaction\r\nOwner 2's\r\nPublic Key\r\nOwner 1's\r\nSignature\r\nHash\r\nVerify\r\nTransaction\r\nOwner 3's\r\nPublic Key\r\nOwner 2's\r\nSignature\r\nHash\r\nVerify\r\nOwner 2's\r\nPrivate Key\r\nOwner 1's\r\nPrivate Key\r\nSign\r\nSign\r\nOwner 3's\r\nPrivate Key\r\n4. Proof-of-Work\r\nTo implement a distributed timestamp server on a peer-to-peer basis, we will need to use a proofof-work system similar to Adam Back's Hashcash [6], rather than newspaper or Usenet posts.\r\nThe proof-of-work involves scanning for a value that when hashed, such as with SHA-256, the\r\nhash begins with a number of zero bits. The average work required is exponential in the number\r\nof zero bits required and can be verified by executing a single hash.\r\nFor our timestamp network, we implement the proof-of-work by incrementing a nonce in the\r\nblock until a value is found that gives the block's hash the required zero bits. Once the CPU\r\neffort has been expended to make it satisfy the proof-of-work, the block cannot be changed\r\nwithout redoing the work. As later blocks are chained after it, the work to change the block\r\nwould include redoing all the blocks after it.\r\nThe proof-of-work also solves the problem of determining representation in majority decision\r\nmaking. If the majority were based on one-IP-address-one-vote, it could be subverted by anyone\r\nable to allocate many IPs. Proof-of-work is essentially one-CPU-one-vote. The majority\r\ndecision is represented by the longest chain, which has the greatest proof-of-work effort invested\r\nin it. If a majority of CPU power is controlled by honest nodes, the honest chain will grow the\r\nfastest and outpace any competing chains. To modify a past block, an attacker would have to\r\nredo the proof-of-work of the block and all blocks after it and then catch up with and surpass the\r\nwork of the honest nodes. We will show later that the probability of a slower attacker catching up\r\ndiminishes exponentially as subsequent blocks are added.\r\nTo compensate for increasing hardware speed and varying interest in running nodes over time,\r\nthe proof-of-work difficulty is determined by a moving average targeting an average number of\r\nblocks per hour. If they're generated too fast, the difficulty increases.\r\n5. Network\r\nThe steps to run the network are as follows:\r\n1) New transactions are broadcast to all nodes.\r\n2) Each node collects new transactions into a block.\r\n3) Each node works on finding a difficult proof-of-work for its block.\r\n4) When a node finds a proof-of-work, it broadcasts the block to all nodes.\r\n5) Nodes accept the block only if all transactions in it are valid and not already spent.\r\n6) Nodes express their acceptance of the block by working on creating the next block in the\r\nchain, using the hash of the accepted block as the previous hash.\r\nNodes always consider the longest chain to be the correct one and will keep working on\r\nextending it. If two nodes broadcast different versions of the next block simultaneously, some\r\nnodes may receive one or the other first. In that case, they work on the first one they received,\r\nbut save the other branch in case it becomes longer. The tie will be broken when the next proofof-work is found and one branch becomes longer; the nodes that were working on the other\r\nbranch will then switch to the longer one.\r\n3\r\nBlock\r\nPrev Hash Nonce\r\nTx Tx ...\r\nBlock\r\nPrev Hash Nonce\r\nTx Tx ...\r\nNew transaction broadcasts do not necessarily need to reach all nodes. As long as they reach\r\nmany nodes, they will get into a block before long. Block broadcasts are also tolerant of dropped\r\nmessages. If a node does not receive a block, it will request it when it receives the next block and\r\nrealizes it missed one.\r\n6. Incentive\r\nBy convention, the first transaction in a block is a special transaction that starts a new coin owned\r\nby the creator of the block. This adds an incentive for nodes to support the network, and provides\r\na way to initially distribute coins into circulation, since there is no central authority to issue them.\r\nThe steady addition of a constant of amount of new coins is analogous to gold miners expending\r\nresources to add gold to circulation. In our case, it is CPU time and electricity that is expended.\r\nThe incentive can also be funded with transaction fees. If the output value of a transaction is\r\nless than its input value, the difference is a transaction fee that is added to the incentive value of\r\nthe block containing the transaction. Once a predetermined number of coins have entered\r\ncirculation, the incentive can transition entirely to transaction fees and be completely inflation\r\nfree.\r\nThe incentive may help encourage nodes to stay honest. If a greedy attacker is able to\r\nassemble more CPU power than all the honest nodes, he would have to choose between using it\r\nto defraud people by stealing back his payments, or using it to generate new coins. He ought to\r\nfind it more profitable to play by the rules, such rules that favour him with more new coins than\r\neveryone else combined, than to undermine the system and the validity of his own wealth.\r\n7. Reclaiming Disk Space\r\nOnce the latest transaction in a coin is buried under enough blocks, the spent transactions before\r\nit can be discarded to save disk space. To facilitate this without breaking the block's hash,\r\ntransactions are hashed in a Merkle Tree [7][2][5], with only the root included in the block's hash.\r\nOld blocks can then be compacted by stubbing off branches of the tree. The interior hashes do\r\nnot need to be stored.\r\nA block header with no transactions would be about 80 bytes. If we suppose blocks are\r\ngenerated every 10 minutes, 80 bytes * 6 * 24 * 365 = 4.2MB per year. With computer systems\r\ntypically selling with 2GB of RAM as of 2008, and Moore's Law predicting current growth of\r\n1.2GB per year, storage should not be a problem even if the block headers must be kept in\r\nmemory.\r\n4\r\nBlock Block\r\nBlock Header (Block Hash)\r\nPrev Hash Nonce\r\nHash01\r\nHash0 Hash1 Hash2 Hash3\r\nHash23\r\nRoot Hash\r\nHash01\r\nHash2\r\nTx3\r\nHash23\r\nBlock Header (Block Hash)\r\nRoot Hash\r\nTransactions Hashed in a Merkle Tree After Pruning Tx0-2 from the Block\r\nPrev Hash Nonce\r\nHash3\r\nTx0 Tx1 Tx2 Tx3\r\n8. Simplified Payment Verification\r\nIt is possible to verify payments without running a full network node. A user only needs to keep\r\na copy of the block headers of the longest proof-of-work chain, which he can get by querying\r\nnetwork nodes until he's convinced he has the longest chain, and obtain the Merkle branch\r\nlinking the transaction to the block it's timestamped in. He can't check the transaction for\r\nhimself, but by linking it to a place in the chain, he can see that a network node has accepted it,\r\nand blocks added after it further confirm the network has accepted it.\r\nAs such, the verification is reliable as long as honest nodes control the network, but is more\r\nvulnerable if the network is overpowered by an attacker. While network nodes can verify\r\ntransactions for themselves, the simplified method can be fooled by an attacker's fabricated\r\ntransactions for as long as the attacker can continue to overpower the network. One strategy to\r\nprotect against this would be to accept alerts from network nodes when they detect an invalid\r\nblock, prompting the user's software to download the full block and alerted transactions to\r\nconfirm the inconsistency. Businesses that receive frequent payments will probably still want to\r\nrun their own nodes for more independent security and quicker verification.\r\n9. Combining and Splitting Value\r\nAlthough it would be possible to handle coins individually, it would be unwieldy to make a\r\nseparate transaction for every cent in a transfer. To allow value to be split and combined,\r\ntransactions contain multiple inputs and outputs. Normally there will be either a single input\r\nfrom a larger previous transaction or multiple inputs combining smaller amounts, and at most two\r\noutputs: one for the payment, and one returning the change, if any, back to the sender.\r\nIt should be noted that fan-out, where a transaction depends on several transactions, and those\r\ntransactions depend on many more, is not a problem here. There is never the need to extract a\r\ncomplete standalone copy of a transaction's history.\r\n5\r\nTransaction\r\nIn\r\n...\r\nIn Out\r\n...\r\nHash01\r\nHash2 Hash3\r\nHash23\r\nBlock Header\r\nMerkle Root\r\nPrev Hash Nonce\r\nBlock Header\r\nMerkle Root\r\nPrev Hash Nonce\r\nBlock Header\r\nMerkle Root\r\nPrev Hash Nonce\r\nMerkle Branch for Tx3\r\nLongest Proof-of-Work Chain\r\nTx3\r\n10. Privacy\r\nThe traditional banking model achieves a level of privacy by limiting access to information to the\r\nparties involved and the trusted third party. The necessity to announce all transactions publicly\r\nprecludes this method, but privacy can still be maintained by breaking the flow of information in\r\nanother place: by keeping public keys anonymous. The public can see that someone is sending\r\nan amount to someone else, but without information linking the transaction to anyone. This is\r\nsimilar to the level of information released by stock exchanges, where the time and size of\r\nindividual trades, the \"tape\", is made public, but without telling who the parties were.\r\nAs an additional firewall, a new key pair should be used for each transaction to keep them\r\nfrom being linked to a common owner. Some linking is still unavoidable with multi-input\r\ntransactions, which necessarily reveal that their inputs were owned by the same owner. The risk\r\nis that if the owner of a key is revealed, linking could reveal other transactions that belonged to\r\nthe same owner.\r\n11. Calculations\r\nWe consider the scenario of an attacker trying to generate an alternate chain faster than the honest\r\nchain. Even if this is accomplished, it does not throw the system open to arbitrary changes, such\r\nas creating value out of thin air or taking money that never belonged to the attacker. Nodes are\r\nnot going to accept an invalid transaction as payment, and honest nodes will never accept a block\r\ncontaining them. An attacker can only try to change one of his own transactions to take back\r\nmoney he recently spent.\r\nThe race between the honest chain and an attacker chain can be characterized as a Binomial\r\nRandom Walk. The success event is the honest chain being extended by one block, increasing its\r\nlead by +1, and the failure event is the attacker's chain being extended by one block, reducing the\r\ngap by -1.\r\nThe probability of an attacker catching up from a given deficit is analogous to a Gambler's\r\nRuin problem. Suppose a gambler with unlimited credit starts at a deficit and plays potentially an\r\ninfinite number of trials to try to reach breakeven. We can calculate the probability he ever\r\nreaches breakeven, or that an attacker ever catches up with the honest chain, as follows [8]:\r\np = probability an honest node finds the next block\r\nq = probability the attacker finds the next block\r\nqz = probability the attacker will ever catch up from z blocks behind\r\nqz={\r\n1 if p≤q\r\nq/ p\r\nz\r\nif pq}\r\n6\r\nIdentities Transactions Trusted\r\nThird Party Counterparty Public\r\nIdentities Transactions Public\r\nNew Privacy Model\r\nTraditional Privacy Model\r\nGiven our assumption that p > q, the probability drops exponentially as the number of blocks the\r\nattacker has to catch up with increases. With the odds against him, if he doesn't make a lucky\r\nlunge forward early on, his chances become vanishingly small as he falls further behind.\r\nWe now consider how long the recipient of a new transaction needs to wait before being\r\nsufficiently certain the sender can't change the transaction. We assume the sender is an attacker\r\nwho wants to make the recipient believe he paid him for a while, then switch it to pay back to\r\nhimself after some time has passed. The receiver will be alerted when that happens, but the\r\nsender hopes it will be too late.\r\nThe receiver generates a new key pair and gives the public key to the sender shortly before\r\nsigning. This prevents the sender from preparing a chain of blocks ahead of time by working on\r\nit continuously until he is lucky enough to get far enough ahead, then executing the transaction at\r\nthat moment. Once the transaction is sent, the dishonest sender starts working in secret on a\r\nparallel chain containing an alternate version of his transaction.\r\nThe recipient waits until the transaction has been added to a block and z blocks have been\r\nlinked after it. He doesn't know the exact amount of progress the attacker has made, but\r\nassuming the honest blocks took the average expected time per block, the attacker's potential\r\nprogress will be a Poisson distribution with expected value:\r\n=z\r\nq\r\np\r\nTo get the probability the attacker could still catch up now, we multiply the Poisson density for\r\neach amount of progress he could have made by the probability he could catch up from that point:\r\n∑\r\nk=0\r\n∞\r\n\r\nk\r\ne\r\n−\r\nk!\r\n⋅{\r\nq/ p\r\nz−k \r\nif k≤z\r\n1 if kz}\r\nRearranging to avoid summing the infinite tail of the distribution...\r\n1−∑\r\nk=0\r\nz\r\n\r\nk\r\ne\r\n−\r\nk!\r\n1−q/ p\r\nz−k \r\n\r\nConverting to C code...\r\n#include <math.h>\r\ndouble AttackerSuccessProbability(double q, int z)\r\n{\r\n double p = 1.0 - q;\r\n double lambda = z * (q / p);\r\n double sum = 1.0;\r\n int i, k;\r\n for (k = 0; k <= z; k++)\r\n {\r\n double poisson = exp(-lambda);\r\n for (i = 1; i <= k; i++)\r\n poisson *= lambda / i;\r\n sum -= poisson * (1 - pow(q / p, z - k));\r\n }\r\n return sum;\r\n}\r\n7\r\nRunning some results, we can see the probability drop off exponentially with z.\r\nq=0.1\r\nz=0 P=1.0000000\r\nz=1 P=0.2045873\r\nz=2 P=0.0509779\r\nz=3 P=0.0131722\r\nz=4 P=0.0034552\r\nz=5 P=0.0009137\r\nz=6 P=0.0002428\r\nz=7 P=0.0000647\r\nz=8 P=0.0000173\r\nz=9 P=0.0000046\r\nz=10 P=0.0000012\r\nq=0.3\r\nz=0 P=1.0000000\r\nz=5 P=0.1773523\r\nz=10 P=0.0416605\r\nz=15 P=0.0101008\r\nz=20 P=0.0024804\r\nz=25 P=0.0006132\r\nz=30 P=0.0001522\r\nz=35 P=0.0000379\r\nz=40 P=0.0000095\r\nz=45 P=0.0000024\r\nz=50 P=0.0000006\r\nSolving for P less than 0.1%...\r\nP < 0.001\r\nq=0.10 z=5\r\nq=0.15 z=8\r\nq=0.20 z=11\r\nq=0.25 z=15\r\nq=0.30 z=24\r\nq=0.35 z=41\r\nq=0.40 z=89\r\nq=0.45 z=340\r\n12. Conclusion\r\nWe have proposed a system for electronic transactions without relying on trust. We started with\r\nthe usual framework of coins made from digital signatures, which provides strong control of\r\nownership, but is incomplete without a way to prevent double-spending. To solve this, we\r\nproposed a peer-to-peer network using proof-of-work to record a public history of transactions\r\nthat quickly becomes computationally impractical for an attacker to change if honest nodes\r\ncontrol a majority of CPU power. The network is robust in its unstructured simplicity. Nodes\r\nwork all at once with little coordination. They do not need to be identified, since messages are\r\nnot routed to any particular place and only need to be delivered on a best effort basis. Nodes can\r\nleave and rejoin the network at will, accepting the proof-of-work chain as proof of what\r\nhappened while they were gone. They vote with their CPU power, expressing their acceptance of\r\nvalid blocks by working on extending them and rejecting invalid blocks by refusing to work on\r\nthem. Any needed rules and incentives can be enforced with this consensus mechanism.\r\n8\r\nReferences\r\n[1] W. Dai, \"b-money,\" http://www.weidai.com/bmoney.txt, 1998.\r\n[2] H. Massias, X.S.

While the system works well enough for most transactions, it still suffers from the inherent weaknesses of the trust based model. Completely non-reversible transactions are not really possible, since financial institutions cannot avoid mediating disputes. The cost of mediation increases transaction costs, limiting the minimum practical transaction size and cutting off the possibility for small casual transactions, and there is a broader cost in the loss of ability to make non-reversible payments for non-reversible services. With the possibility of reversal, the need for trust spreads. Merchants must be wary of their customers, hassling them for more information than they would otherwise need. A certain percentage of fraud is accepted as unavoidable. These costs and payment uncertainties can be avoided in person by using physical currency, but no mechanism exists to make payments over a communications channel without a trusted party.\r\n\r\n互联网商业几乎完全依赖金融机构作为可信第三方去处理电子支付。虽然针对大多数交易来说，这个系统还算不错，但，它仍然被基于信任的模型所固有的缺陷所拖累。完全不可逆转的交易实际上并不可能，因为金融机构不能避免仲裁争议。仲裁成本增加了交易成本，进而限制了最小可能交易的规模，且干脆阻止了很多小额支付交易。除此之外，还有更大的成本：系统无法为那些不可逆的服务提供不可逆的支付。逆转的可能性，造成了对于信任的需求无所不在。商家必须提防着他们的顾客，麻烦顾客提供若非如此（如若信任）就并不必要的更多信息。一定比例的欺诈，被认为是不可避免的。这些成本和支付不确定性，虽然在人与人之间直接使用物理货币支付的时候是可以避免的；但，没有任何一个机制能在双方在其中一方不被信任的情况下通过沟通渠道进行支付。\r\n\r\nWhat is needed is an electronic payment system based on cryptographic proof instead of trust, allowing any two willing parties to transact directly with each other without the need for a trusted third party. Transactions that are computationally impractical to reverse would protect sellers from fraud, and routine escrow mechanisms could easily be implemented to protect buyers. In this paper, we propose a solution to the double-spending problem using a peer-to-peer distributed timestamp server to generate computational proof of the chronological order of transactions. The system is secure as long as honest nodes collectively control more CPU power than any cooperating group of attacker nodes.\r\n\r\n我们真正需要的是一种基于加密证明而非基于信任的电子支付系统，允许任意双方在不需要信任第三方的情况下直接交易。算力保障的不可逆转交易能帮助卖家不被欺诈，而保护买家的日常担保机制也很容易实现。在本论文中，我们将提出一种针对双重支出的解决方案，使用点对点的、分布式的时间戳服务器去生成基于算力的证明，按照时间顺序记录每条交易。此系统是安全的，只要诚实节点总体上相对于相互合作的攻击者掌握更多的 CPU 算力。\r\n\r\n2. 交易 (Transactions)\r\n\r\nWe define an electronic coin as a chain of digital signatures. Each owner transfers the coin to the next by digitally signing a hash of the previous transaction and the public key of the next owner and adding these to the end of the coin. A payee can verify the signatures to verify the chain of ownership.\r\n\r\n我们将一枚电子硬币定义为一个数字签名链。一位所有者将一枚硬币交给另一个人的时候，要通过在这个数字签名链的末尾附加上以下数字签名：上一笔交易的哈希（hash，音译，亦翻译为“散列值”），以及新所有者的公钥。收款人可以通过验证签名去验证数字签名链的所属权。\r\n\r\nThe problem of course is the payee can't verify that one of the owners did not double-spend the coin. A common solution is to introduce a trusted central authority, or mint, that checks every transaction for double spending. After each transaction, the coin must be returned to the mint to issue a new coin, and only coins issued directly from the mint are trusted not to be double-spent. The problem with this solution is that the fate of the entire money system depends on the company running the mint, with every transaction having to go through them, just like a bank.\r\n\r\n这个路径的问题在于收款人无法验证曾经的所有者之中没有人双重支付过。常见的解决方案是引入一个可信的中心化权威方，或称“铸币厂”，让它去检查每一笔交易是否存在双重支付。每一次发生交易之后，硬币必须返回到铸币厂，铸币厂再发行一枚新的硬币。进而，只有铸币厂直接发行的硬币才是可信的、未被双重支付过的。这个解决方案的问题在于，整个货币系统的命运被拴在运营铸币厂的那个公司（就好像银行那样）身上，每一笔交易必须通过它。\r\n\r\nWe need a way for the payee to know that the previous owners did not sign any earlier transactions. For our purposes, the earliest transaction is the one that counts, so we don't care about later attempts to double-spend. The only way to confirm the absence of a transaction is to be aware of all transactions. In the mint based model, the mint was aware of all transactions and decided which arrived first. To accomplish this without a trusted party, transactions must be publicly announced1, and we need a system for participants to agree on a single history of the order in which they were received. The payee needs proof that at the time of each transaction, the majority of nodes agreed it was the first received.\r\n\r\n我们需要一种方式，可以让收款人确认之前的所有者并没有在任何之前的交易上签名。就我们的目的而言，只有最早的交易是算数的，所以，我们并不关心其后的双重支付企图。确认一笔交易不存在的唯一方法是获悉所有的交易。在铸币厂模型之中，铸币厂已然知悉所有的交易，并且能够确认这些交易的顺序。为了能在没有“被信任的一方”参与的情况下完成以上任务，交易记录必须被公开宣布1，进而我们需要一个系统能让参与者们认同它们所接收到的同一个唯一的交易历史。收款人需要证明在每笔交易发生之时，大多数节点能够认同它是第一个被接收的。\r\n\r\n3. 时间戳服务器 (Timestamp Server)\r\n\r\nThe solution we propose begins with a timestamp server. A timestamp server works by taking a hash of a block of items to be timestamped and widely publishing the hash, such as in a newspaper or Usenet post2 3 4 5. The timestamp proves that the data must have existed at the time, obviously, in order to get into the hash. Each timestamp includes the previous timestamp in its hash, forming a chain, with each additional timestamp reinforcing the ones before it.\r\n\r\n本解决方案起步于一种时间戳服务器。时间戳服务器是这样工作的：为一组（block）记录（items）的哈希打上时间戳，而后把哈希广播出去，就好像一份报纸所做的那样，或者像是在新闻组（Usenet）里的一个帖子那样2 3 4 5。显然，时间戳能够证明那数据在那个时间点之前已然存在，否则那哈希也就无法生成。每个时间戳在其哈希中包含着之前的时间戳，因此构成了一个链；每一个新的时间戳被添加到之前的时间戳之后。\r\n\r\n4. 工作证明 (Proof-of-Work)\r\n\r\nTo implement a distributed timestamp server on a peer-to-peer basis, we will need to use a proof-of-work system similar to Adam Back's Hashcash6, rather than newspaper or Usenet posts. The proof-of-work involves scanning for a value that when hashed, such as with SHA-256, the hash begins with a number of zero bits. The average work required is exponential in the number of zero bits required and can be verified by executing a single hash.\r\n\r\n为了实现一个基于点对点的分布式时间戳服务器，我们需要使用类似亚当·伯克的哈希现金6那样的一个工作证明系统，而不是报纸或者新闻组帖子那样的东西。所谓的工作证明，就是去寻找一个数值；这个数值要满足以下条件：为它提取散列数值之后 —— 例如使用 SHA-256 计算散列数值 —— 这个散列数值必须以一定数量的 0 开头。每增加一个 0 的要求，将使得工作量指数级增加，并且，这个工作量的验证却只需通过计算一个哈希。\r\n\r\nFor our timestamp network, we implement the proof-of-work by incrementing a nonce in the block until a value is found that gives the block's hash the required zero bits. Once the CPU effort has been expended to make it satisfy the proof-of-work, the block cannot be changed without redoing the work. As later blocks are chained after it, the work to change the block would include redoing all the blocks after it.\r\n\r\n在我们的时间戳网络中，我们是这样实现工作证明的：不断在区块之中增加一个随机数（Nonce），直到一个满足条件的数值被找到；这个条件就是，这个区块的哈希以指定数量的 0 开头。一旦 CPU 的耗费算力所获的的结果满足工作证明，那么这个区块将不再能被更改，除非重新完成之前的所有工作量。随着新的区块不断被添加进来，改变当前区块即意味着说要重新完成所有其后区块的工作。\r\n\r\nThe proof-of-work also solves the problem of determining representation in majority decision making. If the majority were based on one-IP-address-one-vote, it could be subverted by anyone able to allocate many IPs. Proof-of-work is essentially one-CPU-one-vote. The majority decision is represented by the longest chain, which has the greatest proof-of-work effort invested in it. If a majority of CPU power is controlled by honest nodes, the honest chain will grow the fastest and outpace any competing chains. To modify a past block, an attacker would have to redo the proof-of-work of the block and all blocks after it and then catch up with and surpass the work of the honest nodes. We will show later that the probability of a slower attacker catching up diminishes exponentially as subsequent blocks are added.\r\n\r\n工作证明同时解决了如何决定谁能代表大多数做决定的问题。如果所谓的“大多数”是基于“一个IP地址一票”的方式决定的话，那么任何一个可以搞定很多 IP 地址的人就可以被认为是“大多数”。工作证明本质上来看，是“一个CPU一票”。所谓的“大多数决定”是由最长链所代表的，因为被投入最多工作的链就是它。如果大多数 CPU 算力被诚实的节点所控制，那么诚实链成长最为迅速，其速度会远超其他竞争链。为了更改一个已经产生的区块，攻击者将不得不重新完成那个区块以及所有其后区块的的工作证明，而后还要追上并超过诚实节点的工作。后文展示为什么一个被拖延了的攻击者能够追上的可能性将随着区块的不断增加而指数级降低。\r\n\r\nTo compensate for increasing hardware speed and varying interest in running nodes over time, the proof-of-work difficulty is determined by a moving average targeting an average number of blocks per hour. If they're generated too fast, the difficulty increases.\r\n\r\n为了应对硬件算力综合的不断增加，以及随着时间推进可能产生的节点参与数量变化，工作证明难度由此决定：基于平均每小时产生的区块数量的一个移动平均值。如果区块生成得过快，那么难度将会增加。\r\n\r\n5. 网络 (Network)\r\n\r\nThe steps to run the network are as follows:\r\n\r\n1.New transactions are broadcast to all nodes.\r\n\r\n2.Each node collects new transactions into a block.\r\n\r\n3.Each node works on finding a difficult proof-of-work for its block.\r\n\r\n4.When a node finds a proof-of-work, it broadcasts the block to all nodes.\r\n\r\n5.Nodes accept the block only if all transactions in it are valid and not already spent.\r\n\r\n6.Nodes express their acceptance of the block by working on creating the next block in the chain, using the hash of the accepted block as the previous hash.\r\n\r\n运行网络的步骤如下：\r\n\r\n1.所有新的交易向所有节点广播；\r\n\r\n2.每个节点将新交易打包到一个区块；\r\n\r\n3.每个节点开始为此区块找一个具备难度的工作证明；\r\n\r\n4.当某个区块找到其工作证明，它就要将此区块广播给所有节点；\r\n\r\n5.众多其他节点当且只当以下条件满足才会接受这个区块：其中所有的交易都是有效的，且未被双重支付；\r\n\r\n6.众多节点向网络表示自己接受这个区块的方法是，在创建下一个区块的时候，把被接受区块的哈希当作新区块之前的哈希。\r\n\r\nNodes always consider the longest chain to be the correct one and will keep working on extending it. If two nodes broadcast different versions of the next block simultaneously, some nodes may receive one or the other first. In that case, they work on the first one they received, but save the other branch in case it becomes longer. The tie will be broken when the next proof-of-work is found and one branch becomes longer; the nodes that were working on the other branch will then switch to the longer one.\r\n\r\n节点始终认为最长链是正确的那个，且会不断向其添加新数据。若是有两个节点同时向网络广播了两个不同版本的“下一个区块”，有些节点会先接收到其中一个，而另外一些节点会先接收到另外一个。这种情况下，节点将在它们先接收到的那个区块上继续工作，但也会把另外一个分支保存下来，以防后者成为最长链。当下一个工作证明被找到，而其中的一个分支成为更长的链之后，这个暂时的分歧会被打消，在另外一个分支上工作的节点们会切换到更长的链上。\r\n\r\nNew transaction broadcasts do not necessarily need to reach all nodes. As long as they reach many nodes, they will get into a block before long. Block broadcasts are also tolerant of dropped messages. If a node does not receive a block, it will request it when it receives the next block and realizes it missed one.\r\n\r\n新的交易不见得一定要广播到达所有的节点。只要到达足够多的节点，那么没多久这些交易就会被打包进一个区块。区块广播也容许一些消息被丢弃。如果一个节点并未接收到某个区块，那么这个节点会在它接收到下一个区块的时候意识到自己错失了之前的区块，因此会发出补充那个遗失区块的请求。\r\n\r\n6. 奖励 (Incentive)\r\n\r\nBy convention, the first transaction in a block is a special transaction that starts a new coin owned by the creator of the block. This adds an incentive for nodes to support the network, and provides a way to initially distribute coins into circulation, since there is no central authority to issue them. The steady addition of a constant of amount of new coins is analogous to gold miners expending resources to add gold to circulation. In our case, it is CPU time and electricity that is expended.\r\n\r\n按照约定，每个区块的第一笔交易是一个特殊的交易，它会生成一枚新的硬币，所属权是这个区块的生成者。这么做，使得节点支持网络有所奖励，也提供了一种将硬币发行到流通之中的方式 —— 在这个系统中，反正也没有一个中心化的权威方去发行那些硬币。如此这般稳定地增加一定数量的新硬币进入流通，就好像是黄金开采者不断耗用他们的资源往流通之中增加黄金一样。在我们的系统中，被耗用的资源是 CPU 工作时间和它们所用的电力。\r\n\r\nThe incentive can also be funded with transaction fees. If the output value of a transaction is less than its input value, the difference is a transaction fee that is added to the incentive value of the block containing the transaction. Once a predetermined number of coins have entered circulation, the incentive can transition entirely to transaction fees and be completely inflation free.\r\n\r\n奖励还可以来自交易费用。如果一笔交易的输出值小于它的输入值，那么其中的差额就是交易费；而该交易费就是用来奖励节点把该交易打包进此区块的。一旦既定数量的硬币已经进入流通，那么奖励将全面交由交易手续费来完成，且绝对不会有通货膨胀。\r\n\r\nThe incentive may help encourage nodes to stay honest. If a greedy attacker is able to assemble more CPU power than all the honest nodes, he would have to choose between using it to defraud people by stealing back his payments, or using it to generate new coins. He ought to find it more profitable to play by the rules, such rules that favour him with more new coins than everyone else combined, than to undermine the system and the validity of his own wealth.\r\n\r\n奖励机制也可能会鼓励节点保持诚实。如果一个贪婪的攻击者能够网罗比所有诚实节点都更多的 CPU 算力，他必须做出一个选择：是用这些算力通过把自己花出去的钱偷回来去欺骗别人呢？还是用这些算力去生成新的硬币？他应该能够发现按照规则行事是更划算的，当前规则使得他能够获得比所有其他人加起来都更多的硬币，这显然比暗中摧毁系统并使自己的财富化为虚无更划算。\r\n\r\n7. 回收硬盘空间 (Reclaiming Disk Space)\r\n\r\nOnce the latest transaction in a coin is buried under enough blocks, the spent transactions before it can be discarded to save disk space. To facilitate this without breaking the block's hash, transactions are hashed in a Merkle Tree257, with only the root included in the block's hash. Old blocks can then be compacted by stubbing off branches of the tree. The interior hashes do not need to be stored.\r\n\r\n如果一枚硬币最近发生的交易发生在足够多的区块之前，那么，这笔交易之前该硬币的花销交易记录可以被丢弃 —— 目的是为了节省磁盘空间。为了在不破坏该区块的哈希的前提下实现此功能，交易记录的哈希将被纳入一个 Merkle 树257之中，而只有树根被纳入该区块的哈希之中。通过砍掉树枝方法，老区块即可被压缩。内部的哈希并不需要被保存。\r\n\r\n\r\n\r\nA block header with no transactions would be about 80 bytes. If we suppose blocks are generated every 10 minutes, 80 bytes * 6 * 24 * 365 = 4.2MB per year. With computer systems typically selling with 2GB of RAM as of 2008, and Moore's Law predicting current growth of 1.2GB per year, storage should not be a problem even if the block headers must be kept in memory.\r\n\r\n一个没有任何交易记录的区块头大约是 80 个字节。假设每十分钟产生一个区块，80 字节乘以 6 乘以 24 乘以 365，等于每年 4.2M。截止 2008 年，大多数在售的计算机配有 2GB 内存，而按照摩尔定律的预测，每年会增加 1.2 GB，即便是区块头必须存储在内存之中也不会是什么问题。\r\n\r\n8. 简化版支付确认 (Simplified Payment Verification)\r\n\r\nIt is possible to verify payments without running a full network node. A user only needs to keep a copy of the block headers of the longest proof-of-work chain, which he can get by querying network nodes until he's convinced he has the longest chain, and obtain the Merkle branch linking the transaction to the block it's timestamped in. He can't check the transaction for himself, but by linking it to a place in the chain, he can see that a network node has accepted it, and blocks added after it further confirm the network has accepted it.\r\n\r\n即便不用运行一个完整网络节点也有可能确认支付。用户只需要有一份拥有工作证明的最长链的区块头拷贝 —— 他可以通过查询在线节点确认自己拥有的确实来自最长链 —— 而后获取 Merkle 树的树枝节点，进而连接到这个区块被打上时间戳时的交易。用户并不能自己检查交易，但，通过连接到链上的某个地方，他可以看到某个网络节点已经接受了这个交易，而此后加进来的区块进一步确认了网络已经接受了此笔交易。\r\n\r\nAs such, the verification is reliable as long as honest nodes control the network, but is more vulnerable if the network is overpowered by an attacker. While network nodes can verify transactions for themselves, the simplified method can be fooled by an attacker's fabricated transactions for as long as the attacker can continue to overpower the network. One strategy to protect against this would be to accept alerts from network nodes when they detect an invalid block, prompting the user's software to download the full block and alerted transactions to confirm the inconsistency. Businesses that receive frequent payments will probably still want to run their own nodes for more independent security and quicker verification.\r\n\r\n只要诚实节点依然在掌控网络，如此这般，验证即为可靠的。然而，如果网络被攻击者所控制的时候，验证就没那么可靠了。尽管网络节点可以自己验证交易记录，但是，只要攻击者能够继续控制网络的话，那么简化版验证方式可能会被攻击者伪造的交易记录所欺骗。应对策略之一是，客户端软件要接受来自网络节点的警告。当网络节点发现无效区块的时候，即发出警报，在用户的软件上弹出通知，告知用户下载完整区块，警告用户确认交易一致性。那些有高频收付发生的商家应该仍然希望运行属于自己的完整节点，以此保证更独立的安全性和更快的交易确认。\r\n\r\n9. 价值的组合与分割 (Combining and Splitting Value)\r\n\r\nAlthough it would be possible to handle coins individually, it would be unwieldy to make a separate transaction for every cent in a transfer. To allow value to be split and combined, transactions contain multiple inputs and outputs. Normally there will be either a single input from a larger previous transaction or multiple inputs combining smaller amounts, and at most two outputs: one for the payment, and one returning the change, if any, back to the sender.\r\n\r\n尽管逐个地处理硬币是可能的，但为每分钱设置一个单独的记录是很笨拙的。为了允许价值的分割与合并，交易记录包含多个输入和输出。一般情况下，要么是一个单独的来自于一个相对大的之前的交易的输入，要么是很多个输入来自于更小金额的组合；与此同时，最多有两个输出：一个是支付（指向收款方），如果必要的话，另外一个是找零（指向发款方）。\r\n\r\nIt should be noted that fan-out, where a transaction depends on several transactions, and those transactions depend on many more, is not a problem here. There is never the need to extract a complete standalone copy of a transaction's history.\r\n\r\n值得注意的是，“扇出”在这里并不是问题 —— 所谓“扇出”，就是指一笔交易依赖于数笔交易，且这些交易又依赖于更多笔交易。从来就没有必要去提取任何一笔交易的完整独立的历史拷贝。\r\n\r\n10. 隐私 (Privacy)\r\n\r\nThe traditional banking model achieves a level of privacy by limiting access to information to the parties involved and the trusted third party. The necessity to announce all transactions publicly precludes this method, but privacy can still be maintained by breaking the flow of information in another place: by keeping public keys anonymous. The public can see that someone is sending an amount to someone else, but without information linking the transaction to anyone. This is similar to the level of information released by stock exchanges, where the time and size of individual trades, the \"tape\", is made public, but without telling who the parties were.\r\n\r\n传统的银行模型通过限制他人获取交易者和可信第三方的信息而达成一定程度的隐私保护。出于对将所有交易记录公开的需求否决了这种方法。但是，维持隐私可通过于另一处的切断信息流来实现——公钥匿名。公众可以看到某某向某某转账了一定的金额，但是，没有任何信息指向某个确定的人。这种水平的信息发布有点像股市交易，只有时间和各个交易的金额被公布，但是，没有人知道交易双方都是谁。\r\n\r\nAs an additional firewall, a new key pair should be used for each transaction to keep them from being linked to a common owner. Some linking is still unavoidable with multi-input transactions, which necessarily reveal that their inputs were owned by the same owner. The risk is that if the owner of a key is revealed, linking could reveal other transactions that belonged to the same owner.\r\n\r\n还有另外一层防火墙。交易者应该针对每一笔交易启用一对新的公私钥，以便他人无法将这些交易追溯到同一个所有者身上。有些多输入的交易依然难免被追溯，因为那些输入必然会被识别出来自于同一个所有者。危险在于，如果一个公钥的所有者被曝光之后，与之相关的所有其他交易都会被曝光。\r\n\r\n11. 计算 (Calculations)\r\n\r\nWe consider the scenario of an attacker trying to generate an alternate chain faster than the honest chain. Even if this is accomplished, it does not throw the system open to arbitrary changes, such as creating value out of thin air or taking money that never belonged to the attacker. Nodes are not going to accept an invalid transaction as payment, and honest nodes will never accept a block containing them. An attacker can only try to change one of his own transactions to take back money he recently spent.\r\n\r\n假设一个场景，某个攻击者正在试图生成一个比诚实链更快的替代链。就算他成功了，也不会使当前系统置于模棱两可的尴尬境地，即，他不可能凭空制造出价值，也无法获取从未属于他的钱。网络节点不会把一笔无效交易当作支付，而诚实节点也永远不会接受一个包含这种支付的区块。攻击者最多只能修改属于他自己的交易，进而试图取回他已经花出去的钱。\r\n\r\nThe race between the honest chain and an attacker chain can be characterized as a Binomial Random Walk. The success event is the honest chain being extended by one block, increasing its lead by +1, and the failure event is the attacker's chain being extended by one block, reducing the gap by -1.\r\n\r\n诚实链和攻击者之间的竞争可以用二项式随机漫步来描述。成功事件是诚实链刚刚被添加了一个新的区块，使得它的优势增加了1；而失败事件是攻击者的链刚刚被增加了一个新的区块，使得诚实链的优势减少了1。\r\n\r\nThe probability of an attacker catching up from a given deficit is analogous to a Gambler's Ruin problem. Suppose a gambler with unlimited credit starts at a deficit and plays potentially an infinite number of trials to try to reach breakeven. We can calculate the probability he ever reaches breakeven, or that an attacker ever catches up with the honest chain, as follows8:\r\n\r\n攻击者能够从落后局面追平的概率类似于赌徒破产问题。假设，一个拿着无限筹码的赌徒，从亏空开始，允许他赌无限次，目标是填补上已有的亏空。我们能算出他最终能填补亏空的概率，也就是攻击者能够赶上诚实链的概率8，如下：\r\n\r\n  p = 诚实节点找到下一个区块的概率\r\n\r\n  q = 攻击者找到下一个区块的概率\r\n\r\nqz = 攻击者落后 z 个区块却依然能够赶上的概率\r\n\r\n qz={ 1     ifp ≤ q               \r\n (q/p)z   ifp > q     }\r\n\r\nGiven our assumption that p > q, the probability drops exponentially as the number of blocks the attacker has to catch up with increases. With the odds against him, if he doesn't make a lucky lunge forward early on, his chances become vanishingly small as he falls further behind.\r\n\r\n既然我们已经假定p > q , 既然攻击者需要赶超的区块数量越来越多，那么其成功概率就会指数级下降。于赢面不利时，如果攻击者没有在起初就能幸运地向前猛跨一步，那么他的胜率将在他进一步落后的同时消弭殆尽。\r\n\r\nWe now consider how long the recipient of a new transaction needs to wait before being sufficiently certain the sender can't change the transaction. We assume the sender is an attacker who wants to make the recipient believe he paid him for a while, then switch it to pay back to himself after some time has passed. The receiver will be alerted when that happens, but the sender hopes it will be too late.\r\n\r\n现在考虑一下一笔新交易的收款人需要等多久才能充分确定发款人不能更改这笔交易。我们假定发款人是个攻击者，妄图让收款人在一段时间里相信他已经支付对付款项，随后将这笔钱再转回给自己。发生这种情况时，收款人当然会收到警告，但发款人希望那时木已成舟。\r\n\r\nThe receiver generates a new key pair and gives the public key to the sender shortly before signing. This prevents the sender from preparing a chain of blocks ahead of time by working on it continuously until he is lucky enough to get far enough ahead, then executing the transaction at that moment. Once the transaction is sent, the dishonest sender starts working in secret on a parallel chain containing an alternate version of his transaction.\r\n\r\n收款人生成了一对新的公私钥，而后在签署之前不久将公钥告知发款人。这样可以防止一种情形：发款人提前通过连续运算去准备一条链上的区块，并且只要有足够的运气就会足够领先，直到那时再执行交易。一旦款项已被发出，那个不诚实的发款人开始秘密地在另一条平行链上开工，试图在其中加入一个反向版本的交易。\r\n\r\nThe recipient waits until the transaction has been added to a block and  blocks have been linked after it. He doesn't know the exact amount of progress the attacker has made, but assuming the honest blocks took the average expected time per block, the attacker's potential progress will be a Poisson distribution with expected value:\r\n\r\n收款人等到此笔交易被打包进区块，并已经有  个区块随后被加入。他并不知道攻击者的工作进展究竟如何，但是可以假定诚实区块在每个区块生成过程中耗费的平均时间；攻击者的潜在进展符合泊松分布，其期望值为：.....\r\n\r\nTo get the probability the attacker could still catch up now, we multiply the Poisson density for each amount of progress he could have made by the probability he could catch up from that point:\r\n\r\n为了算出攻击者依然可以赶上的概率，我们要把每一个攻击者已有的进展的帕松密度乘以他可以从那一点能够追上来的概率：\r\n......\r\n\r\nRearranging to avoid summing the infinite tail of the distribution...\r\n\r\n为了避免对密度分布的无穷级数求和重新整理…\r\n\r\nConverting to C code...\r\n\r\n转换为 C 语言程序…\r\n\r\n#include <math.h>\r\n\r\ndouble AttackerSuccessProbability(double q, int z)\r\n\r\n{\r\n\r\n    double p = 1.0 - q;\r\n    double lambda = z * (q / p);\r\n    double sum = 1.0;\r\n    int i, k;\r\n    for (k = 0; k <= z; k++)\r\n    {\r\n        double poisson = exp(-lambda);\r\n        for (i = 1; i <= k; i++)\r\n            poisson *= lambda / i;\r\n        sum -= poisson * (1 - pow(q / p, z - k));\r\n    }\r\n    return sum;\r\n}\r\n\r\nRunning some results, we can see the probability drop off exponentially with z .\r\n\r\n获取部分结果，我们可以看到概率随着 z 的增加指数级下降：\r\n\r\n q=0.1\r\n\r\n   z=0    P=1.0000000\r\n\r\n   z=1    P=0.2045873\r\n\r\n   z=2    P=0.0509779\r\n\r\n   z=3    P=0.0131722\r\n\r\n   z=4    P=0.0034552\r\n\r\n   z=5    P=0.0009137\r\n\r\n   z=6    P=0.0002428\r\n\r\n   z=7    P=0.0000647\r\n\r\n   z=8    P=0.0000173\r\n\r\n   z=9    P=0.0000046\r\n\r\n   z=10   P=0.0000012\r\n\r\n   \r\n   q=0.3\r\n\r\n   z=0    P=1.0000000\r\n\r\n   z=5    P=0.1773523\r\n\r\n   z=10   P=0.0416605\r\n\r\n   z=15   P=0.0101008\r\n\r\n   z=20   P=0.0024804\r\n\r\n   z=25   P=0.0006132\r\n\r\n   z=30   P=0.0001522\r\n\r\n   z=35   P=0.0000379\r\n\r\n   z=40   P=0.0000095\r\n\r\n   z=45   P=0.0000024\r\n\r\n   z=50   P=0.0000006\r\n\r\n12. 结论 (Conclusion)\r\n\r\nWe have proposed a system for electronic transactions without relying on trust. We started with the usual framework of coins made from digital signatures, which provides strong control of ownership, but is incomplete without a way to prevent double-spending. To solve this, we proposed a peer-to-peer network using proof-of-work to record a public history of transactions that quickly becomes computationally impractical for an attacker to change if honest nodes control a majority of CPU power. The network is robust in its unstructured simplicity. Nodes work all at once with little coordination. They do not need to be identified, since messages are not routed to any particular place and only need to be delivered on a best effort basis.

A purely peer-to-peer version of electronic cash would allow online payments to be sent directly from one party to another without going through a financial institution. Digital signatures provide part of the solution, but the main benefits are lost if a trusted third party is still required to prevent double-spending. We propose a solution to the double-spending problem using a peer-to-peer network. The network timestamps transactions by hashing them into an ongoing chain of hash-based proof-of-work, forming a record that cannot be changed without redoing the proof-of-work. The longest chain not only serves as proof of the sequence of events witnessed, but proof that it came from the largest pool of CPU power. As long as a majority of CPU power is controlled by nodes that are not cooperating to attack the network, they’ll generate the longest chain and outpace attackers. The network itself requires minimal structure. Messages are broadcast on a best effort basis, and nodes can leave and rejoin the network at will, accepting the longest proof-of-work chain as proof of what happened while they were gone.  \r\n**1.Introduction**  \r\nCommerce on the Internet has come to rely almost exclusively on financial institutions serving as trusted third parties to process electronic payments. While the system works well enough for most transactions, it still suffers from the inherent weaknesses of the trust based model. Completely non-reversible transactions are not really possible, since financial institutions cannot avoid mediating disputes. The cost of mediation increases transaction costs, limiting the minimum practical transaction size and cutting off the possibility for small casual transactions, and there is a broader cost in the loss of ability to make non-reversible payments for non-reversible services. With the possibility of reversal, the need for trust spreads. Merchants must be wary of their customers, hassling them for more information than they would otherwise need. A certain percentage of fraud is accepted as unavoidable. These costs and payment uncertainties can be avoided in person by using physical currency, but no mechanism exists to make payments over a communications channel without a trusted party.\r\nWhat is needed is an electronic payment system based on cryptographic proof instead of trust, allowing any two willing parties to transact directly with each other without the need for a trusted third party. Transactions that are computationally impractical to reverse would protect sellers from fraud, and routine escrow mechanisms could easily be implemented to protect buyers. In this paper, we propose a solution to the double-spending problem using a peer-to-peer distributed timestamp server to generate computational proof of the chronological order of transactions. The system is secure as long as honest nodes collectively control more CPU power than any cooperating group of attacker nodes.  \r\n**2.Transactions **   \r\nWe define an electronic coin as a chain of digital signatures. Each owner transfers the coin to the next by digitally signing a hash of the previous transaction and the public key of the next owner and adding these to the end of the coin. A payee can verify the signatures to verify the chain of ownership.\r\nThe problem of course is the payee can’t verify that one of the owners did not double-spend the coin. A common solution is to introduce a trusted central authority, or mint, that checks every transaction for double spending. After each transaction, the coin must be returned to the mint to issue a new coin, and only coins issued directly from the mint are trusted not to be double-spent. The problem with this solution is that the fate of the entire money system depends on the company running the mint, with every transaction having to go through them, just like a bank.\r\nWe need a way for the payee to know that the previous owners did not sign any earlier transactions. For our purposes, the earliest transaction is the one that counts, so we don’t care about later attempts to double-spend. The only way to confirm the absence of a transaction is to be aware of all transactions. In the mint based model, the mint was aware of all transactions and decided which arrived first. To accomplish this without a trusted party, transactions must be publicly announced1, and we need a system for participants to agree on a single history of the order in which they were received. The payee needs proof that at the time of each transaction, the majority of nodes agreed it was the first received.\r\n**3.Timestamp Server **   \r\nThe solution we propose begins with a timestamp server. A timestamp server works by taking a hash of a block of items to be timestamped and widely publishing the hash, such as in a newspaper or Usenet post2 3 4 5. The timestamp proves that the data must have existed at the time, obviously, in order to get into the hash. Each timestamp includes the previous timestamp in its hash, forming a chain, with each additional timestamp reinforcing the ones before it.\r\n\r\nTo implement a distributed timestamp server on a peer-to-peer basis, we will need to use a proof-of-work system similar to Adam Back’s Hashcash6, rather than newspaper or Usenet posts. The proof-of-work involves scanning for a value that when hashed, such as with SHA-256, the hash begins with a number of zero bits. The average work required is exponential in the number of zero bits required and can be verified by executing a single hash.\r\n\r\nFor our timestamp network, we implement the proof-of-work by incrementing a nonce in the block until a value is found that gives the block’s hash the required zero bits. Once the CPU effort has been expended to make it satisfy the proof-of-work, the block cannot be changed without redoing the work. As later blocks are chained after it, the work to change the block would include redoing all the blocks after it.\r\n\r\nThe proof-of-work also solves the problem of determining representation in majority decision making. If the majority were based on one-IP-address-one-vote, it could be subverted by anyone able to allocate many IPs. Proof-of-work is essentially one-CPU-one-vote. The majority decision is represented by the longest chain, which has the greatest proof-of-work effort invested in it. If a majority of CPU power is controlled by honest nodes, the honest chain will grow the fastest and outpace any competing chains. To modify a past block, an attacker would have to redo the proof-of-work of the block and all blocks after it and then catch up with and surpass the work of the honest nodes. We will show later that the probability of a slower attacker catching up diminishes exponentially as subsequent blocks are added.\r\n\r\nTo compensate for increasing hardware speed and varying interest in running nodes over time, the proof-of-work difficulty is determined by a moving average targeting an average number of blocks per hour. If they’re generated too fast, the difficulty increases.\r\n\r\nThe steps to run the network are as follows:\r\n\r\n New transactions are broadcast to all nodes.\r\nEach node collects new transactions into a block.\r\nEach node works on finding a difficult proof-of-work for its block.\r\nWhen a node finds a proof-of-work, it broadcasts the block to all nodes.\r\nNodes accept the block only if all transactions in it are valid and not already spent.\r\nNodes express their acceptance of the block by working on creating the next block in the chain, using the hash of the accepted block as the previous hash.\r\n\r\nNodes always consider the longest chain to be the correct one and will keep working on extending it. If two nodes broadcast different versions of the next block simultaneously, some nodes may receive one or the other first. In that case, they work on the first one they received, but save the other branch in case it becomes longer. The tie will be broken when the next proof-of-work is found and one branch becomes longer; the nodes that were working on the other branch will then switch to the longer one.\r\n\r\nNew transaction broadcasts do not necessarily need to reach all nodes. As long as they reach many nodes, they will get into a block before long. Block broadcasts are also tolerant of dropped messages. If a node does not receive a block, it will request it when it receives the next block and realizes it missed one.By convention, the first transaction in a block is a special transaction that starts a new coin owned by the creator of the block. This adds an incentive for nodes to support the network, and provides a way to initially distribute coins into circulation, since there is no central authority to issue them. The steady addition of a constant of amount of new coins is analogous to gold miners expending resources to add gold to circulation. In our case, it is CPU time and electricity that is expended.The incentive can also be funded with transaction fees. If the output value of a transaction is less than its input value, the difference is a transaction fee that is added to the incentive value of the block containing the transaction. Once a predetermined number of coins have entered circulation, the incentive can transition entirely to transaction fees and be completely inflation free.The incentive may help encourage nodes to stay honest. If a greedy attacker is able to assemble more CPU power than all the honest nodes, he would have to choose between using it to defraud people by stealing back his payments, or using it to generate new coins. He ought to find it more profitable to play by the rules, such rules that favour him with more new coins than everyone else combined, than to undermine the system and the validity of his own wealth.\r\n\r\nOnce the latest transaction in a coin is buried under enough blocks, the spent transactions before it can be discarded to save disk space. To facilitate this without breaking the block’s hash, transactions are hashed in a Merkle Tree257, with only the root included in the block’s hash. Old blocks can then be compacted by stubbing off branches of the tree. The interior hashes do not need to be stored.\r\n\r\nIt is possible to verify payments without running a full network node. A user only needs to keep a copy of the block headers of the longest proof-of-work chain, which he can get by querying network nodes until he’s convinced he has the longest chain, and obtain the Merkle branch linking the transaction to the block it’s timestamped in. He can’t check the transaction for himself, but by linking it to a place in the chain, he can see that a network node has accepted it, and blocks added after it further confirm the network has accepted it.As such, the verification is reliable as long as honest nodes control the network, but is more vulnerable if the network is overpowered by an attacker. While network nodes can verify transactions for themselves, the simplified method can be fooled by an attacker’s fabricated transactions for as long as the attacker can continue to overpower the network. One strategy to protect against this would be to accept alerts from network nodes when they detect an invalid block, prompting the user’s software to download the full block and alerted transactions to confirm the inconsistency. Businesses that receive frequent payments will probably still want to run their own nodes for more independent security and quicker verification.\r\n\r\nAlthough it would be possible to handle coins individually, it would be unwieldy to make a separate transaction for every cent in a transfer. To allow value to be split and combined, transactions contain multiple inputs and outputs. Normally there will be either a single input from a larger previous transaction or multiple inputs combining smaller amounts, and at most two outputs: one for the payment, and one returning the change, if any, back to the sender.It should be noted that fan-out, where a transaction depends on several transactions, and those transactions depend on many more, is not a problem here. There is never the need to extract a complete standalone copy of a transaction’s history.\r\n\r\nThe traditional banking model achieves a level of privacy by limiting access to information to the parties involved and the trusted third party. The necessity to announce all transactions publicly precludes this method, but privacy can still be maintained by breaking the flow of information in another place: by keeping public keys anonymous. The public can see that someone is sending an amount to someone else, but without information linking the transaction to anyone. This is similar to the level of information released by stock exchanges, where the time and size of individual trades, the “tape”, is made public, but without telling who the parties were.As an additional firewall, a new key pair should be used for each transaction to keep them from being linked to a common owner. Some linking is still unavoidable with multi-input transactions, which necessarily reveal that their inputs were owned by the same owner. The risk is that if the owner of a key is revealed, linking could reveal other transactions that belonged to the same owner.\r\n\r\nWe consider the scenario of an attacker trying to generate an alternate chain faster than the honest chain. Even if this is accomplished, it does not throw the system open to arbitrary changes, such as creating value out of thin air or taking money that never belonged to the attacker. Nodes are not going to accept an invalid transaction as payment, and honest nodes will never accept a block containing them. An attacker can only try to change one of his own transactions to take back money he recently spent.The race between the honest chain and an attacker chain can be characterized as a Binomial Random Walk. The success event is the honest chain being extended by one block, increasing its lead by +1, and the failure event is the attacker’s chain being extended by one block, reducing the gap by -1.The probability of an attacker catching up from a given deficit is analogous to a Gambler’s Ruin problem. Suppose a gambler with unlimited credit starts at a deficit and plays potentially an infinite number of trials to try to reach breakeven. We can calculate the probability he ever reaches breakeven, or that an attacker ever catches up with the honest chain, as follows8:Given our assumption that p > q, the probability drops exponentially as the number of blocks the attacker has to catch up with increases. With the odds against him, if he doesn’t make a lucky lunge forward early on, his chances become vanishingly small as he falls further behind.We now consider how long the recipient of a new transaction needs to wait before being sufficiently certain the sender can’t change the transaction. We assume the sender is an attacker who wants to make the recipient believe he paid him for a while, then switch it to pay back to himself after some time has passed. The receiver will be alerted when that happens, but the sender hopes it will be too late.The receiver generates a new key pair and gives the public key to the sender shortly before signing. This prevents the sender from preparing a chain of blocks ahead of time by working on it continuously until he is lucky enough to get far enough ahead, then executing the transaction at that moment. Once the transaction is sent, the dishonest sender starts working in secret on a parallel chain containing an alternate version of his transaction.The recipient waits until the transaction has been added to a block and z blocks have been linked after it. He doesn’t know the exact amount of progress the attacker has made, but assuming the honest blocks took the average expected time per block, the attacker’s potential progress will be a Poisson distribution with expected value![](https://arweave.net/htzHw5lgHV6sEOZOy4fSFoxV3qzyYn1TKH2cYkwS8Ls):To get the probability the attacker could still catch up now, we multiply the Poisson density for each amount of progress he could have made by the probability he could catch up from that point![](https://arweave.net/uQIC5JT2EqUbKwR282Q1ZSTZqPG6w084iR9tpl0irGI)Rearranging to avoid summing the infinite tail of the distribution…![](https://arweave.net/DIQP8mbhtMrL6kHZmupmDaXrekOA-AYbT1SgoymK1a4)\r\nConverting to C code…\r\n```\r\n#include <math.h>\r\ndouble AttackerSuccessProbability(double q, int z)\r\n{\r\ndouble p = 1.0 – q;\r\ndouble lambda = z * (q / p);\r\ndouble sum = 1.0;\r\nint i, k;\r\nfor (k = 0; k <= z; k++)\r\n{\r\ndouble poisson = exp(-lambda);\r\nfor (i = 1; i <= k; i++)\r\npoisson *= lambda / i;\r\nsum -= poisson * (1 – pow(q / p, z – k));\r\n}\r\nreturn sum; }\r\n\r\nRunning some results, we can see the probability drop off exponentially with z.\r\n```\r\n``\r\n\r\n\r\n\r\n\r\n\r\n```\r\nq=0.1\r\nz=0 P=1.0000000\r\nz=1 P=0.2045873\r\nz=2 P=0.0509779\r\nz=3 P=0.0131722\r\nz=4 P=0.0034552\r\nz=5 P=0.0009137\r\nz=6 P=0.0002428\r\nz=7 P=0.0000647\r\nz=8 P=0.0000173\r\nz=9 P=0.0000046\r\nz=10 P=0.0000012\r\nq=0.3\r\nz=0 P=1.0000000\r\nz=5 P=0.1773523\r\nz=10 P=0.0416605\r\nz=15 P=0.0101008\r\nz=20 P=0.0024804\r\nz=25 P=0.0006132\r\nz=30 P=0.0001522\r\nz=35 P=0.0000379\r\nz=40 P=0.0000095\r\nz=45 P=0.0000024\r\nz=50 P=0.0000006\r\n\r\nSolving for P less than 0.1%…\r\nP < 0.001\r\nq=0.10 z=5\r\nq=0.15 z=8\r\nq=0.20 z=11\r\nq=0.25 z=15\r\nq=0.30 z=24\r\nq=0.35 z=41\r\nq=0.40 z=89\r\nq=0.45 z=340\r\n```\r\n**12.Conclusion**  \r\nWe have proposed a system for electronic transactions without relying on trust. We started with the usual framework of coins made from digital signatures, which provides strong control of ownership, but is incomplete without a way to prevent double-spending. To solve this, we proposed a peer-to-peer network using proof-of-work to record a public history of transactions that quickly becomes computationally impractical for an attacker to change if honest nodes control a majority of CPU power. The network is robust in its unstructured simplicity. Nodes work all at once with little coordination. They do not need to be identified, since messages are not routed to any particular place and only need to be delivered on a best effort basis. Nodes can leave and rejoin the network at will, accepting the proof-of-work chain as proof of what happened while they were gone. They vote with their CPU power, expressing their acceptance of valid blocks by working on extending them and rejecting invalid blocks by refusing to work on them.

Bitwise**\r\n\r\nBitwise Asset Management已于6月16日向美国SEC提交一份新申请文件，要求修改规则以适应其计划中的Bitwise Bitcoin ETP Trust。\r\n\r\n美国SEC曾于2022年6月拒绝Bitwise提交的比特币现货ETF申请，并认为该ETF无法实现充分监督共享，也无法提供针对市场操纵的保护措施并证明相关市场规模庞大。\r\n\r\n今年4月，Bitwise首席投资官Matt Hougan表示，虽然从长远来看，现货比特币ETF对投资者来说是“极好的”，但Bitwise可能会等到监管更加明确后再推出另一只ETF。\r\n\r\n在新提交的文件中，BitWise表示美国SEC应该在45-90天内批准、拒绝或围绕其拟议的规则变更启动其他处理程序。据悉，该申请由纽约证券交易平台（NYSE）发布，但暂未经过美国SEC处理，这意味着目前尚不清楚相关申请的实际截止日期。\r\n\r\n**1.4.4. Invesco Galaxy Bitcoin ETF**\r\n\r\nGalaxy Digital 和 Invesco 于 2021 年 9 月 22 日联合提交了一只比特币 ETF，名为Invesco Galaxy Bitcoin ETF。根据该文件，其 ETF 也将由比特币“实物支持”，而不是通过期货等衍生品。Invesco Capital Management LLC是该申请的发起人，但目前尚不清楚哪家公司将托管该申请的比特币。\r\n\r\n保荐人是 Invesco Ltd 的全资子公司，该公司也是美国第四大 ETF 提供商，这一资质可能有助于提交申请。Invesco 美国 ETF 策略主管John Hoffman表示：“对于长期从事 ETF 业务的人来说，这与 ETF 的早期（1990 年代末、2000 年代初）非常相似。”\r\n\r\n此产品是两家公司希望在美国市场上市的一系列加密 ETF 中的第一个。\r\n\r\n**1.4.5. WisdomTree**\r\n\r\n总部位于纽约的资产管理公司 WisdomTree 已经拥有运营比特币 ETF 的经验；它于 2019 年在瑞士的SIX交易平台推出了一款比特币 ETF。在 2021 年 3 月加入了美国比特币 ETF 的候选者行列，向 SEC 提交了S-1文件，提议在 Cboe bZx 交易平台上市 WisdomTree 比特币信托，股票代码为BTCW。\r\n\r\n此后，SEC一再拖延，先是征求公众对该提案的反馈，然后宣布需要更多时间来考虑评论信中“提出的问题”。\r\n\r\nSEC 于 2021 年底拒绝了 WisdomTree 的申请，大约在同一时间，它也拒绝了 Valkyrie 和 Kryptoin 的类似申请。在贝莱德提交申请后不久，WisdomTree于 2023 年中期提交了一份新申请。\r\n\r\n**1.4.6. Valkyrie Investments**\r\n\r\n作为较新的参与者，资产管理公司 Valkyrie于 2021 年 1 月提交了第一份比特币 ETF 申请。该 ETF 将参考芝加哥商业交易平台（CME）的比特币参考价格并在纽约证券交易平台 Arca 进行交易，该公司在提案中写道：“为投资者提供了一种有效的手段实施各种投资策略”，加密货币托管方 Xapo 负责托管和冷存储该基金的比特币。\r\n\r\n在该文件中，Valkyrie 提到了加密货币的波动性——这是 SEC 对比特币 ETF 的主要担忧之一。它在风险评估中表示：“比特币交易平台失败的潜在后果可能会对股票的价值产生不利影响”。\r\n\r\n毫不意外，SEC 推迟了对 Valkyrie 的申请的裁决，同时还推迟了对 Kryptoin、WisdomTree 和 Global X 的申请的裁决，最终在2021 年圣诞节前后拒绝了 Valkyrie和 Kryptoin 的申请。\r\n\r\n2022 年初，Valkyrie 的比特币矿业 ETF成功获得SEC 批准 。该工具由平均使用 77% 可再生能源的公司持股支持，其中包括 Argo Blockchain、Bitfarms、Cleanspark、Hive Blockchain 和 Stronghold Digital Mining 等行业重量级公司。\r\n\r\n2023 年 6 月，Valkyrie向 SEC提交了另一份比特币现货 ETF 申请。\r\n\r\n**1.4.7. 富达 Fidelity**\r\n\r\n管理着约 11 万亿美元资产的金融服务巨头富达于6月29日提交了申请，该 ETF 以 Wise Origin Bitcoin Trust 名义备案。根据该文件，富达数字资产服务公司将“负责托管该信托基金的比特币”。\r\n\r\n与贝莱德不同的是，富达此前曾尝试推出现货比特币 ETF。该公司于 2021 年提交了 Wise Origin Bitcoin Trust 申请，这是一项拟议的 ETF，最终于 2022 年 1 月被 SEC否决。这一拒绝是在 Fidelity在加拿大成功推出现货比特币 ETF近两个月后发生的。\r\n\r\n富达多年前就开始涉足加密领域， 它于 2018 年推出 Fidelity Digital Assets，为对冲基金、家族办公室和市场中介机构等机构投资者提供加密货币托管和交易执行服务。并在 2022 年 4 月推出了加密行业和数字支付 ETF (FDIG) 和 Fidelity Metaverse ETF (FMET)。\r\n\r\n**以上资料参考：**\r\n\r\n作者：比推BitpushNews Mary Liu / \r\n\r\n来源：https://www.bitpush.news/articles/4577810\r\n\r\n\r\n**1.5. 比特币ETF的审批情况**\r\n\r\n*SEC 十年来驳回了全部的现货 ETF 申请\r\n\r\n*期货 ETF 已有部分获得SEC批准：如 ProShares 和 Valkyrie 推出基于期货的比特币 ETF\r\n\r\n*全球 ETF 批准：加拿大、澳大利亚、巴西和一些欧洲国家的监管机构已经批准了比特币 ETF，这给 SEC 带来了压力。\r\n\r\n\r\n\r\n**1.6. 比特币资产管理规模**\r\n\r\n需要理解的是，虽然美国从未有过比特币现货 ETF，但已经有大量的投资投入到现有的结构中，包括信托，例如 Grayscale 比特币信托(GBTC)、美国的基于期货的 ETF、美国以外的基于现货的 ETF 和私人基金。我们的分析显示，这些产品的资产管理规模为 288 亿美元，其中 276亿美元投资于现货产品。注意：我们的测量并未包含美国以外可能存在的私人基金，这些基金更难以整合。\r\n\r\n![](https://arweave.net/iZ47zr_Kcgx6QHsSwwvFT7SpYS-Ibfx9J1iI2zMBnCY) \r\n","creator":"0x6a78b98e57941c0600d34a52169328011ff3dcce","if_to_text_assets_k_v":true,"likes":0,"tags":{},"author_true":"0x6a78b98e57941c0600d34a52169328011ff3dcce","space_contract_addr":"0x0","share_holders":[]},{"id":190,"created_at":"2023-12-17T17:02:04.213564+00:00","id_on_chain":1416,"content":"**从零学习比特币（六）——比特币的价值**\r\n\r\n**1. 第六章 比特币的价值**\r\n\r\n比特币不受中央银行监管，基于比特币稀缺性、去中心化、不可篡改性，通常将其视为类似于黄金的价值储蓄手段。\r\n\r\n**1.1. 比特币的交易数据**\r\n\r\n2023年9月30日，交易数据如下\r\n\r\n名称：Bitcoin (BTC)\r\n\r\n流通供应量：19,500,150 BTC\r\n\r\n总供应量：19,500,150 BTC\r\n\r\n最大供应量：21,000,000 BTC\r\n\r\n当前价格：$26,997.03\r\n\r\n市值：$526,446,074,255.18\r\n\r\n市值占比：48.84%\r\n\r\n完全摊薄市值：$566,937,600,000\r\n\r\n\r\n\r\n**1.2. 比特币通胀率**\r\n\r\n截止今天，已经被挖出的比特币有1950万个，而根据统计有将近160万个BTC因为各种原因已经遗失，所以目前流通的比特币约为1790万个。\r\n\r\n根据之前计算，目前每天挖出的比特币数量约为900个，一年约为32.85万个，通胀率约为1.68%\r\n\r\n在2024年减半之后，预计通胀率每年仅为0.84%。\r\n\r\n\r\n\r\n**1.3. 比特币与黄金对比**\r\n\r\n比特币因为其储值价值，经常被拿来与黄金相比。\r\n\r\n目前全球已经开采出来的黄金大约20万吨，每年的产量大约3000吨左右。按照60美元每克的价格，一吨黄金大约0.6亿美元，黄金的总价值为12万亿美元。全球央行的储备大约3.5万吨，折合美元刚刚超过2万亿美元。\r\n\r\nBTC 目前5.2千亿美元的市值相当于黄金的4.3% 左右","creator":"0x6a78b98e57941c0600d34a52169328011ff3dcce","if_to_text_assets_k_v":true,"likes":0,"tags":{},"author_true":"0x6a78b98e57941c0600d34a52169328011ff3dcce","space_contract_addr":"0x0","share_holders":[]},{"id":185,"created_at":"2023-12-17T16:59:05.73423+00:00","id_on_chain":1392,"content":"**从零学习比特币（四）——比特币的扩容**\r\n\r\n\r\n从结果上来看，BTC限制容量走向以价值存储为核心功能的大宗投资品；BCH保持去中心化密码货币目标，继续迎合市场需求推进支付功能。\r\n\r\n**1.1. 扩容问题的背景**\r\n\r\n因中本聪于2010年7月设置了最大1M的区块容量限制，比特币的区块大小限制为1MB，这意味着每10分钟只能处理大约7笔交易。随着比特币的普及，交易数量的增加导致了网络拥堵和交易费用的上涨。这引发了关于如何扩容比特币以处理更多交易的争论。\r\n\r\n\r\n**1.2. 主要的扩容提议**\r\n\r\n**1.2.1. Segregated Witness (SegWit)**\r\n\r\n详细描述：SegWit的主要目的是修复交易可变性问题。它通过将交易的某些部分（见证数据）移出主区块来实现。这不仅可以容纳更多的交易，还可以为二层解决方案，如闪电网络，提供基础。\r\n\r\n优势：提高了区块的容量，修复了交易可变性问题，为二层解决方案铺平了道路。\r\n\r\n劣势：尽管SegWit提供了一定程度的扩展性，但它并没有根本解决比特币的扩容问题。\r\n\r\n状态: 2017年，SegWit被比特币网络采纳。\r\n\r\n**1.2.2. 比特币现金 (Bitcoin Cash)**\r\n\r\n描述: 由于对扩容方法的分歧，2017年8月1日，比特币进行了硬分叉，产生了比特币现金。比特币现金的主要特点是增大了区块大小，最初为8MB，后来进一步扩大。\r\n\r\n优势：提供了更大的交易吞吐量。\r\n\r\n劣势：增大区块大小可能导致中心化，因为只有大型矿工才能处理更大的区块。\r\n\r\n状态: 比特币现金作为一个独立的加密货币存在，与比特币并行。\r\n\r\n**1.2.3. 比特币SV (Bitcoin SV)**\r\n\r\n描述: 2018年，比特币现金再次分叉，产生了比特币SV。比特币SV进一步增大了区块大小，宣称更接近中本聪的原始愿景。\r\n\r\n优势：更大的区块大小。\r\n\r\n劣势：与比特币现金相似，增大区块大小可能导致中心化。\r\n\r\n状态: 比特币SV作为一个独立的加密货币存在。\r\n\r\n\r\n**1.3. 二层解决方案**\r\n\r\n**1.3.1. 闪电网络 (Lightning Network)**\r\n\r\n描述: 闪电网络是一个建立在比特币之上的二层支付协议。它允许用户在链下进行即时交易，这些交易不会立即广播到比特币区块链。只有当通道关闭或发生争议时，交易才会被广播。从而大大提高了比特币的交易吞吐量。\r\n\r\n优势：提供即时交易，极低的费用，提高交易吞吐量。\r\n\r\n劣势：仍然处于开发阶段，可能存在安全问题。\r\n\r\n状态: 闪电网络正在被广泛采纳，并有多个实现版本。\r\n\r\n**1.3.2. 侧链 (Sidechains)**\r\n\r\n描述: 侧链是与主链并行运行的独立链，允许资产在两条链之间转移。这可以为比特币提供扩展性，同时不改变主链的规则。\r\n\r\n优势：提供扩展性，允许实验新功能。\r\n\r\n劣势：安全性可能不如主链。\r\n\r\n目前的侧链有：\r\n\r\nLiquid：由Blockstream开发，主要用于交易所之间的快速资金转移。\r\n\r\nRSK (Rootstock)：将以太坊兼容的智能合约功能带到比特币。\r\n\r\nDrivechain：允许比特币通过侧链支持各种应用，如匿名交易、更快的交易等。\r\n\r\n状态: 有多个侧链项目正在开发中。\r\n\r\n**1.4. 其他提议**\r\n\r\n**1.4.1. Schnorr签名**\r\n\r\n描述: Schnorr签名是一种新的签名方案，可以减少交易的大小并提高隐私性。它还允许多个输入的交易进行聚合，从而进一步减少交易大小。\r\n\r\n状态: Schnorr签名的提议正在考虑中。\r\n\r\n**1.4.2. Taproot**\r\n\r\n描述: Taproot结合了Schnorr签名和Merkleized Abstract Syntax Trees (MAST)来提高隐私性和扩展性。它允许用户隐藏未使用的交易输出，从而提高隐私性。\r\n\r\n状态: Taproot的提议正在考虑中。\r\n\r\n总的来说，比特币扩容问题及其解决方案是一个复杂的话题，涉及多个技术、社区和经济因素，更涉及到很多有意思的历史事件。","creator":"0x6a78b98e57941c0600d34a52169328011ff3dcce","if_to_text_assets_k_v":true,"likes":0,"tags":{},"author_true":"0x6a78b98e57941c0600d34a52169328011ff3dcce","space_contract_addr":"0x0","share_holders":[]},{"id":181,"created_at":"2023-12-17T16:57:04.617854+00:00","id_on_chain":1373,"content":"从零学习比特币（三）——比特币相关的重要组织\r\n\r\n这些组织和社区为比特币的开发、推广和使用起到了重要作用\r\n\r\n1.1.

就是一个 `Block` 数组。\r\n\r\n现在，让我们能够给它添加一个区块：\r\n\r\n```rust\r\n/// add block\r\npub fn add_block(&mut self, data: String) -> Result<()> {\r\n    let prev_block = self.blocks.last().ok_or(anyhow::anyhow!(\"no block\"))?;\r\n    let new_block = Block::new(data.as_bytes().to_vec(), prev_block.hash);\r\n    self.blocks.push(new_block);\r\n    Ok(())\r\n}\r\n```\r\n\r\n结束！不过，就这样就完成了吗？\r\n\r\n为了加入一个新的块，我们必须要有一个已有的块，但是，初始状态下，我们的链是空的，一个块都没有！所以，在任何一个区块链中，都必须至少有一个块。这个块，也就是链中的第一个块，通常叫做创世块（**genesis block**）. 让我们实现一个方法来创建创世块：\r\n\r\n```rust\r\n/// genesis block\r\nlet genesis_block = Block::new(\"Genesis Block\".as_bytes().to_vec(), [0; 32]);\r\n```\r\n\r\n现在，我们可以实现一个函数来创建有创世块的区块链：\r\n\r\n```rust\r\n/// genesis block\r\npub fn new_genesis_block() -> Self {\r\n    let genesis_block = Block::new(\"Genesis Block\".as_bytes().to_vec(), [0; 32]);\r\n    Self {\r\n        blocks: vec![genesis_block],\r\n    }\r\n}\r\n```\r\n\r\n检查一个我们的区块链是否如期工作：\r\n\r\n```rust\r\n/// Start the application.\r\nfn run(&self) {\r\n    let mut new_blockchain = Blockchain::new_genesis_block();\r\n    if let Err(e) = new_blockchain.add_block(\"Send 1 BTC to Ivan\".into()) {\r\n        println!(\"Error: {}\", e);\r\n    }\r\n    if let Err(e) = new_blockchain.add_block(\"Send 2 more BTC to Ivan\".into()) {\r\n        println!(\"Error: {}\", e);\r\n    }\r\n\r\n    println!(\"{}\", new_blockchain);\r\n}\r\n```\r\n\r\n输出：\r\n\r\n```bash\r\nPrev. hash:\r\nData: Genesis Block\r\nHash: aff955a50dc6cd2abfe81b8849eab15f99ed1dc333d38487024223b5fe0f1168\r\n\r\nPrev. hash: aff955a50dc6cd2abfe81b8849eab15f99ed1dc333d38487024223b5fe0f1168\r\nData: Send 1 BTC to Ivan\r\nHash: d75ce22a840abb9b4e8fc3b60767c4ba3f46a0432d3ea15b71aef9fde6a314e1\r\n\r\nPrev. hash: d75ce22a840abb9b4e8fc3b60767c4ba3f46a0432d3ea15b71aef9fde6a314e1\r\nData: Send 2 more BTC to Ivan\r\nHash: 561237522bb7fcfbccbc6fe0e98bbbde7427ffe01c6fb223f7562288ca2295d1\r\n```\r\n\r\n## 总结\r\n\r\n我们创建了一个非常简单的区块链原型：它仅仅是一个数组构成的一系列区块，每个块都与前一个块相关联。真实的区块链要比这复杂得多。在我们的区块链中，加入新的块非常简单，也很快，但是在真实的区块链中，加入新的块需要很多工作：你必须要经过十分繁重的计算（这个机制叫做工作量证明），来获得添加一个新块的权力。并且，区块链是一个分布式数据库，并且没有单一决策者。因此，要加入一个新块，必须要被网络的其他参与者确认和同意（这个机制叫做共识（consensus））。还有一点，我们的区块链还没有任何的交易！\r\n\r\n进入 demo-bitcoin 目录查看代码，执行 `cargo run -- run` 即可运行：\r\n\r\n```bash\r\n$ cd demo-bitcoin\r\n$ cargo run -- run\r\n    Finished dev [unoptimized + debuginfo] target(s) in 0.01s\r\n     Running `target/debug/demo-bitcoin run`\r\nPrev. hash:\r\nData: Genesis Block\r\nHash: 4693b71eee96760de4b0f051083376dcbed2f0711a44294ee5fd42fbeacc9579\r\n\r\nPrev. hash: 4693b71eee96760de4b0f051083376dcbed2f0711a44294ee5fd42fbeacc9579\r\nData: Send 1 BTC to Ivan\r\nHash: 839380a2d0af1dc4686f16ade5423fecdc5f287db9322d9e18adcb4071e7c8ff\r\n\r\nPrev. hash: 839380a2d0af1dc4686f16ade5423fecdc5f287db9322d9e18adcb4071e7c8ff\r\nData: Send 2 more BTC to Ivan\r\nHash: b38052a029bd2b1b9d4bb478af45b4c88605e99bc64e49031ba06d21ad4b0b38\r\n```\r\n\r\n参考：\r\n\r\n[1] [Block hashing algorithm](https://en.bitcoin.it/wiki/Block_hashing_algorithm)\r\n\r\n[2] [Building Blockchain in Go.

的demo bitcoin实现 - part1 工作量证明\r\n==========\r\n\r\n在上一节，我们构造了一个非常简单的数据结构 -- 区块，它也是整个区块链数据库的核心。目前所完成的区块链原型，已经可以通过链式关系把区块相互关联起来：每个块都与前一个块相关联。\r\n\r\n但是，当前实现的区块链有一个巨大的缺陷：向链中加入区块太容易，也太廉价了。而区块链和比特币的其中一个核心就是，要想加入新的区块，必须先完成一些非常困难的工作。在本文，我们将会弥补这个缺陷。\r\n\r\n## 工作量证明\r\n\r\n区块链的一个关键点就是，一个人必须经过一系列困难的工作，才能将数据放入到区块链中。正是由于这种困难的工作，才保证了区块链的安全和一致。此外，完成这个工作的人，也会获得相应奖励（这也就是通过挖矿获得币）。\r\n\r\n这个机制与生活现象非常类似：一个人必须通过努力工作，才能够获得回报或者奖励，用以支撑他们的生活。在区块链中，是通过网络中的参与者（矿工）不断的工作来支撑起了整个网络。矿工不断地向区块链中加入新块，然后获得相应的奖励。在这种机制的作用下，新生成的区块能够被安全地加入到区块链中，它维护了整个区块链数据库的稳定性。值得注意的是，完成了这个工作的人必须要证明这一点，即他必须要证明他的确完成了这些工作。\r\n\r\n整个 “努力工作并进行证明” 的机制，就叫做工作量证明（proof-of-work）。要想完成工作非常地不容易，因为这需要大量的计算能力：即便是高性能计算机，也无法在短时间内快速完成。另外，这个工作的困难度会随着时间不断增长，以保持每 10 分钟出 1 个新块的速度。**在比特币中，这个工作就是找到一个块的哈希**，同时这个哈希满足了一些必要条件。这个哈希，也就充当了证明的角色。因此，寻求证明（寻找有效哈希），就是矿工实际要做的事情。\r\n\r\n## 哈希计算\r\n\r\n在本节，我们会讨论哈希计算。如果你已经熟悉了这个概念，可以直接跳过。\r\n\r\n获得指定数据的一个哈希值的过程，就叫做哈希计算。一个哈希，就是对所计算数据的一个唯一表示。对于一个哈希函数，输入任意大小的数据，它会输出一个固定大小的哈希值。下面是哈希的几个关键特性：\r\n\r\n1. 无法从一个哈希值恢复原始数据。也就是说，哈希并不是加密。\r\n2. 对于特定的数据，只能有一个哈希，并且这个哈希是唯一的。\r\n3. 即使是仅仅改变输入数据中的一个字节，也会导致输出一个完全不同的哈希。\r\n\r\n![hashing](../images/hashing-example.png)\r\n\r\n哈希函数被广泛用于检测数据的一致性。软件提供者常常在除了提供软件包以外，还会发布校验和。当下载完一个文件以后，你可以用哈希函数对下载好的文件计算一个哈希，并与作者提供的哈希进行比较，以此来保证文件下载的完整性。\r\n\r\n在区块链中，哈希被用于保证一个块的一致性。哈希算法的输入数据包含了前一个块的哈希，因此使得不太可能（或者，至少很困难）去修改链中的一个块：因为如果一个人想要修改前面一个块的哈希，那么他必须要重新计算这个块以及后面所有块的哈希。\r\n\r\n## Hashcash\r\n\r\n比特币使用 [Hashcash](https://en.wikipedia.org/wiki/Hashcash) ，一个最初用来防止垃圾邮件的工作量证明算法。它可以被分解为以下步骤：\r\n\r\n1. 取一些公开的数据（比如，如果是 email 的话，它可以是接收者的邮件地址；在比特币中，它是区块头）\r\n2. 给这个公开数据添加一个计数器。计数器默认从 0 开始\r\n3. 将  **data(数据)** 和 **counter(计数器)** 组合到一起，获得一个哈希\r\n4. 检查哈希是否符合一定的条件：\r\n   1. 如果符合条件，结束\r\n   2. 如果不符合，增加计数器，重复步骤 3-4\r\n\r\n因此，这是一个暴力算法：改变计数器，计算新的哈希，检查，增加计数器，计算哈希，检查，如此往复。这也是为什么说它的计算成本很高，因为这一步需要如此反复不断地计算和检查。\r\n\r\n现在，让我们来仔细看一下一个哈希要满足的必要条件。在原始的 Hashcash 实现中，它的要求是 “一个哈希的前 20 位必须是 0”。在比特币中，这个要求会随着时间而不断变化。因为按照设计，必须保证每 10 分钟生成一个块，而不论计算能力会随着时间增长，或者是会有越来越多的矿工进入网络，所以需要动态调整这个必要条件。\r\n\r\n为了阐释这一算法，我从前一个例子（“I like donuts”）中取得数据，并且找到了一个前 3 个字节是全是 0 的哈希。\r\n\r\n![a hash that starts with 3 zero-bytes](../images/hashcash-example.png)\r\n\r\n **ca07ca** 是计数器的 16 进制值，十进制的话是 13240266.\r\n\r\n## 实现\r\n\r\n好了，完成了理论层面，来动手写代码吧！首先，定义挖矿的难度值：\r\n\r\n```rust\r\npub const TARGET_BITS: u16 = 24;\r\n```\r\n\r\n在比特币中，当一个块被挖出来以后，“target bits” 代表了区块头里存储的难度，也就是开头有多少个 0。这里的 24 指的是算出来的哈希前 24 位必须是 0，如果用 16 进制表示，就是前 6 位必须是 0，这一点从最后的输出可以看出来。目前我们并不会实现一个动态调整目标的算法，所以将难度定义为一个全局的常量即可。\r\n\r\n24 其实是一个可以任意取的数字，其目的只是为了有一个目标（target）而已，这个目标占据不到 256 位的内存空间。同时，我们想要有足够的差异性，但是又不至于大的过分，因为差异性越大，就越难找到一个合适的哈希。\r\n\r\n```rust\r\n/// ProofOfWork is a struct that holds a block and a target\r\npub struct ProofOfWork {\r\n    /// block is a pointer to a block\r\n    pub block: Block,\r\n    /// target is a pointer to a target\r\n    pub target: BigUint,\r\n}\r\n\r\nimpl ProofOfWork {\r\n    /// new is a constructor for ProofOfWork\r\n    pub fn new(b: Block) -> ProofOfWork {\r\n        let one: BigUint = One::one();\r\n        let target = one << (256u16 - TARGET_BITS);\r\n        ProofOfWork { block: b, target }\r\n    }\r\n\r\n}\r\n```\r\n\r\n这里，我们构造了 **ProofOfWork** 结构，里面存储了指向一个块(`block`)和一个目标(`target`)的指针。这里的 “目标” ，也就是前一节中所描述的必要条件。这里使用了一个 [大整数](https://docs.rs/num-bigint/latest/num_bigint/) ，我们会将哈希与目标进行比较：先把哈希转换成一个大整数，然后检测它是否小于目标。\r\n\r\n在 **ProofOfWork的New** 函数中，我们将 **BigUnit** 初始化为 1，然后左移 `256 - targetBits` 位。**256** 是一个 SHA-256 哈希的位数，我们将要使用的是 SHA-256 哈希算法。**target（目标）** 的 16 进制形式为：\r\n\r\n```\r\n0x10000000000000000000000000000000000000000000000000000000000\r\n```\r\n\r\n它在内存上占据了 29 个字节。下面是与前面例子哈希的形式化比较：\r\n\r\n```\r\n0fac49161af82ed938add1d8725835cc123a1a87b1b196488360e58d4bfb51e3\r\n0000010000000000000000000000000000000000000000000000000000000000\r\n0000008b0f41ec78bab747864db66bcb9fb89920ee75f43fdaaeb5544f7f76ca\r\n```\r\n\r\n第一个哈希（基于 “I like donuts” 计算）比目标要大，因此它并不是一个有效的工作量证明。第二个哈希（基于 “I like donutsca07ca” 计算）比目标要小，所以是一个有效的证明。\r\n\r\n译者注：上面的形式化比较有些“言不符实”，其实它应该并非由 “I like donuts” 而来，但是原文表达的意思是没问题的，可能是疏忽而已。下面是我做的一个小实验：\r\n\r\n```rust\r\nlet data1 = b\"I like donuts\";\r\nlet data2 = b\"I like donutsca07ca\";\r\n\r\nlet one: BigUint = One::one();\r\nlet target = one << (256u16 - TARGET_BITS);\r\n\r\nlet data1_hash = calca_hash(data1);\r\nlet data2_hash = calca_hash(data2);\r\nprintln!(\"{}\", hex::encode(data1_hash));\r\nprintln!(\"{:64x}\", target);\r\nprintln!(\"{}\", hex::encode(data2_hash));\r\n```\r\n\r\n输出：\r\n\r\n```bash\r\nf80867f6efd4484c23b0e7184e53fe4af6ab49b97f5293fcd50d5b2bfa73a4d0\r\n10000000000000000000000000000000000000000000000000000000000\r\n0000002f7c1fe31cb82acdc082cfec47620b7e4ab94f2bf9e096c436fc8cee06\r\n```\r\n\r\n你可以把目标想象为一个范围的上界：如果一个数（由哈希转换而来）比上界要小，那么是有效的，反之无效。因为要求比上界要小，所以会导致有效数字并不会很多。因此，也就需要通过一些困难的工作（一系列反复地计算），才能找到一个有效的数字。\r\n\r\n现在，我们需要有数据来进行哈希，准备数据：\r\n\r\n```rust\r\n/// prepare_data is a method that returns a byte array\r\npub fn prepar_data(&self, nonce: i64) -> Vec<u8> {\r\n    let mut data = vec![];\r\n    data.extend_from_slice(&self.block.prev_block_hash);\r\n    data.extend_from_slice(&self.block.data);\r\n    data.extend_from_slice(&self.block.timestamp.to_be_bytes());\r\n    data.extend_from_slice(&TARGET_BITS.to_be_bytes());\r\n    data.extend_from_slice(&nonce.to_be_bytes());\r\n    data\r\n}\r\n```\r\n\r\n这个部分比较直观：只需要将 target ，nonce 与 Block 进行合并。这里的 `nonce`，就是上面 Hashcash 所提到的计数器，它是一个密码学术语。\r\n\r\n很好，到这里，所有的准备工作就完成了，下面来实现 PoW 算法的核心：\r\n\r\n```rust\r\npub fn run(&self) -> (i64, [u8; 32]) {\r\n    let mut hash = [0u8; 32];\r\n    let mut nonce = 0i64;\r\n    println!(\r\n        \"Mining the block containing \\\"{}\\\"\",\r\n        String::from_utf8_lossy(&self.block.data)\r\n    );\r\n    while nonce < i64::max_value() {\r\n        let data = self.prepar_data(nonce);\r\n        hash = calca_hash(&data);\r\n        let hash_int = BigUint::from_bytes_be(&hash);\r\n        if hash_int < self.target {\r\n            println!(\"\\r{}\", hex::encode(data));\r\n            break;\r\n        } else {\r\n            nonce += 1;\r\n        }\r\n    }\r\n    (nonce, hash)\r\n}\r\n```\r\n\r\n首先我们对变量进行初始化：\r\n\r\n- `HashInt` 是 `hash` 的整形表示；\r\n- `nonce` 是计数器。\r\n\r\n然后开始一个 “无限” 循环：`maxNonce` 对这个循环进行了限制, 它等于 `math.MaxInt64`，这是为了避免 `nonce` 可能出现的溢出。尽管我们 PoW 的难度很小，以至于计数器其实不太可能会溢出，但最好还是以防万一检查一下。\r\n\r\n在这个循环中，我们做的事情有：\r\n\r\n1. 准备数据\r\n2. 用 SHA-256 对数据进行哈希\r\n3. 将哈希转换成一个大整数\r\n4. 将这个大整数与目标进行比较\r\n\r\n跟之前所讲的一样简单。现在我们可以移除 `Block` 的 `SetHash` 方法，然后修改 `NewBlock` 函数：\r\n\r\n```rust\r\nimpl Block {\r\n    /// 创建新块时，需要把上一个块的哈希作为参数传进来\r\n    pub fn new(data: Vec<u8>, prev_block_hash: Hash) -> Self {\r\n        let now = OffsetDateTime::now_utc();\r\n        let timestamp = now.unix_timestamp();\r\n        let mut block = Block {\r\n            timestamp,\r\n            data,\r\n            prev_block_hash,\r\n            hash: [0; 32],\r\n            nonce: 0,\r\n        };\r\n\r\n        let pow = ProofOfWork::new(block.clone());\r\n        let (nonce, hash) = pow.run();\r\n\r\n        block.hash = hash;\r\n        block.nonce = nonce;\r\n        block\r\n    }\r\n}\r\n```\r\n\r\n在这里，你可以看到 `nonce` 被保存为 `Block` 的一个属性。这是十分有必要的，因为待会儿我们对这个工作量进行验证时会用到 `nonce` 。`Block` 结构现在看起来像是这样：\r\n\r\n```rust\r\n#[derive(Debug, Clone)]\r\n/// demo Bitcoin block\r\npub struct Block {\r\n    /// 当前时间戳，也就是区块创建的时间\r\n    pub timestamp: i64,\r\n    /// 区块存储的实际有效信息，也就是交易\r\n    pub data: Vec<u8>,\r\n    /// 前一个块的哈希，即父哈希\r\n    pub prev_block_hash: Hash,\r\n    /// 当前块的哈希\r\n    pub hash: Hash,\r\n    /// nonce\r\n    pub nonce: i64,\r\n}\r\n```\r\n\r\n好了！现在让我们来运行一下是否正常工作：\r\n\r\n```bash\r\nMining the block containing \"Genesis Block\"\r\n00000041662c5fc2883535dc19ba8a33ac993b535da9899e593ff98e1eda56a1\r\n\r\nMining the block

bool {\r\n    let data = self.prepar_data(self.block.nonce);\r\n    let hash = calca_hash(&data);\r\n    let hash_int = BigUint::from_bytes_be(&hash);\r\n    hash_int.cmp(&self.target).is_lt()\r\n}\r\n```\r\n\r\n这里，就是我们就用到了上面保存的 `nonce`。\r\n\r\n再来检测一次是否正常工作：\r\n\r\n```rust\r\nimpl Display for Block {\r\n    fn fmt(&self, f: &mut std::fmt::Formatter<'_>) -> std::fmt::Result {\r\n        let timestamp =\r\n            OffsetDateTime::from_unix_timestamp(self.timestamp).expect(\"convert timestamp error\");\r\n        let pow =

Introduction\r\nCommerce on the Internet has come to rely almost exclusively on financial institutions serving as\r\ntrusted third parties to process electronic payments. While the system works well enough for\r\nmost transactions, it still suffers from the inherent weaknesses of the trust based model.\r\nCompletely non-reversible transactions are not really possible, since financial institutions cannot\r\navoid mediating disputes. The cost of mediation increases transaction costs, limiting the\r\nminimum practical transaction size and cutting off the possibility for small casual transactions,\r\nand there is a broader cost in the loss of ability to make non-reversible payments for non-\r\nreversible services. With the possibility of reversal, the need for trust spreads. Merchants must\r\nbe wary of their customers, hassling them for more information than they would otherwise need.\r\nA certain percentage of fraud is accepted as unavoidable. These costs and payment uncertainties\r\ncan be avoided in person by using physical currency, but no mechanism exists to make payments\r\nover a communications channel without a trusted party.\r\nWhat is needed is an electronic payment system based on cryptographic proof instead of trust,\r\nallowing any two willing parties to transact directly with each other without the need for a trusted\r\nthird party. Transactions that are computationally impractical to reverse would protect sellers\r\nfrom fraud, and routine escrow mechanisms could easily be implemented to protect buyers. In\r\nthis paper, we propose a solution to the double-spending problem using a peer-to-peer distributed\r\ntimestamp server to generate computational proof of the chronological order of transactions. The\r\nsystem is secure as long as honest nodes collectively control more CPU power than any\r\ncooperating group of attacker nodes.\r\n","creator":"0xb702488a6c08e34c6e3274367392fc75b1321346","if_to_text_assets_k_v":true,"likes":0,"tags":{},"author_true":"0xb702488a6c08e34c6e3274367392fc75b1321346","space_contract_addr":"0x0","share_holders":[]},{"id":108,"created_at":"2023-12-17T15:59:04.949699+00:00","id_on_chain":788,"content":"**\r\n## Bitcoin: A Peer-to-Peer Electronic Cash System\r\n**\r\n**Satoshi Nakamoto\r\nsatoshin@gmx.com\r\nwww.bitcoin.org**\r\nAbstract.

Digital signatures provide part of the solution, but the main benefits are lost if a trusted third party is still required to prevent double-spending. We propose a solution to the double-spending problem using a peer-to-peer network. The network timestamps transactions by hashing them into an ongoing chain of hash-based proof-of-work, forming a record that cannot be changed without redoing the proof-of-work. The longest chain not only serves as proof of the sequence of events witnessed, but proof that it came from the largest pool of CPU power. As long as a majority of CPU power is controlled by nodes that are not cooperating to attack the network, they'll generate the longest chain and outpace attackers. The network itself requires minimal structure. Messages are broadcast on a best effort basis, and nodes can leave and rejoin the network at will, accepting the longest proof-of-work chain as proof of what happened while they were gone.\r\n\r\n## 1. Introduction\r\n\r\nCommerce on the Internet has come to rely almost exclusively on financial institutions serving as trusted third parties to process electronic payments. While the system works well enough for most transactions, it still suffers from the inherent weaknesses of the trust based model. Completely non-reversible transactions are not really possible, since financial institutions cannot avoid mediating disputes. The cost of mediation increases transaction costs, limiting the minimum practical transaction size and cutting off the possibility for small casual transactions, and there is a broader cost in the loss of ability to make non-reversible payments for non-reversible services. With the possibility of reversal, the need for trust spreads. Merchants must be wary of their customers, hassling them for more information than they would otherwise need. A certain percentage of fraud is accepted as unavoidable. These costs and payment uncertainties can be avoided in person by using physical currency, but no mechanism exists to make payments over a communications channel without a trusted party.\r\n\r\nWhat is needed is an electronic payment system based on cryptographic proof instead of trust, allowing any two willing parties to transact directly with each other without the need for a trusted third party. Transactions that are computationally impractical to reverse would protect sellers from fraud, and routine escrow mechanisms could easily be implemented to protect buyers. In this paper, we propose a solution to the double-spending problem using a peer-to-peer distributed timestamp server to generate computational proof of the chronological order of transactions. The system is secure as long as honest nodes collectively control more CPU power than any cooperating group of attacker nodes.\r\n\r\n## 2. Transactions\r\n\r\nWe define an electronic coin as a chain of digital signatures. Each owner transfers the coin to the next by digitally signing a hash of the previous transaction and the public key of the next owner and adding these to the end of the coin. A payee can verify the signatures to verify the chain of ownership.\r\n\r\n```\r\n      ┌─────────────────────┐               ┌─────────────────────┐              ┌─────────────────────┐\r\n      │                     │               │                     │              │                     │\r\n      │    Transaction      │               │    Transaction      │              │    Transaction      │\r\n      │                     │               │                     │              │                     │\r\n      │   ┌─────────────┐   │               │   ┌─────────────┐   │              │   ┌─────────────┐   │\r\n      │   │ Owner 1's   │   │               │   │ Owner 2's   │   │              │   │ Owner 3's   │   │\r\n      │   │ Public Key  │   │               │   │ Public Key  │   │              │   │ Public Key  │   │\r\n      │   └───────┬─────┘   │               │   └───────┬─────┘   │              │   └───────┬─────┘   │\r\n      │           │    .    │               │           │    .    │              │           │         │\r\n──────┼─────────┐ │    .    ├───────────────┼─────────┐ │    .    ├──────────────┼─────────┐ │         │\r\n      │         │ │    .    │               │         │ │    .    │              │         │ │         │\r\n      │      ┌──▼─▼──┐ .    │               │      ┌──▼─▼──┐ .    │              │      ┌──▼─▼──┐      │\r\n      │      │ Hash  │ .    │               │      │ Hash  │ .    │              │      │ Hash  │      │\r\n      │      └───┬───┘ .    │    Verify     │      └───┬───┘ .    │    Verify    │      └───┬───┘      │\r\n      │          │     ............................    │     ...........................    │          │\r\n      │          │          │               │     │    │          │              │     │    │          │\r\n      │   ┌──────▼──────┐   │               │   ┌─▼────▼──────┐   │              │   ┌─▼────▼──────┐   │\r\n      │   │ Owner 0's   │   │      Sign     │   │ Owner 1's   │   │      Sign    │   │ Owner 2's   │   │\r\n      │   │ Signature   │   │      ...........─►│ Signature   │   │     ...........─►│ Signature   │   │\r\n      │   └─────────────┘   │      .        │   └─────────────┘   │     .        │   └─────────────┘   │\r\n      │                     │      .        │                     │     .        │                     │\r\n      └─────────────────────┘      .        └─────────────────────┘     .        └─────────────────────┘\r\n                                   .                                    .\r\n          ┌─────────────┐          .            ┌─────────────┐         .            ┌─────────────┐\r\n          │ Owner 1's   │...........            │ Owner 2's   │..........            │ Owner 3's   │\r\n          │ Private Key │                       │ Private Key │                      │ Private Key │\r\n          └─────────────┘                       └─────────────┘                      └─────────────┘\r\n```\r\n\r\nThe problem of course is the payee can't verify that one of the owners did not double-spend the coin. A common solution is to introduce a trusted central authority, or mint, that checks every transaction for double spending. After each transaction, the coin must be returned to the mint to issue a new coin, and only coins issued directly from the mint are trusted not to be double-spent. The problem with this solution is that the fate of the entire money system depends on the company running the mint, with every transaction having to go through them, just like a bank.\r\n\r\nWe need a way for the payee to know that the previous owners did not sign any earlier transactions. For our purposes, the earliest transaction is the one that counts, so we don't care about later attempts to double-spend. The only way to confirm the absence of a transaction is to be aware of all transactions. In the mint based model, the mint was aware of all transactions and decided which arrived first. To accomplish this without a trusted party, transactions must be publicly announced [^1], and we need a system for participants to agree on a single history of the order in which they were received. The payee needs proof that at the time of each transaction, the majority of nodes agreed it was the first received.\r\n\r\n## 3. Timestamp Server\r\n\r\nThe solution we propose begins with a timestamp server. A timestamp server works by taking a hash of a block of items to be timestamped and widely publishing the hash, such as in a newspaper or Usenet post [^2] [^3] [^4] [^5]. The timestamp proves that the data must have existed at the time, obviously, in order to get into the hash. Each timestamp includes the previous timestamp in its hash, forming a chain, with each additional timestamp reinforcing the ones before it.\r\n\r\n```\r\n             ┌──────┐                        ┌──────┐\r\n────────────►│      ├───────────────────────►│      ├───────────────────►\r\n             │ Hash │                        │ Hash │\r\n        ┌───►│      │                   ┌───►│      │\r\n        │    └──────┘                   │    └──────┘\r\n        │                               │\r\n       ┌┴──────────────────────────┐   ┌┴──────────────────────────┐\r\n       │ Block                     │   │ Block                     │\r\n       │ ┌─────┐ ┌─────┐ ┌─────┐   │   │ ┌─────┐ ┌─────┐ ┌─────┐   │\r\n       │ │Item │ │Item │ │...  │   │   │ │Item │ │Item │ │...  │   │\r\n       │ └─────┘ └─────┘ └─────┘   │   │ └─────┘ └─────┘ └─────┘   │\r\n       │                           │   │                           │\r\n       └───────────────────────────┘   └───────────────────────────┘\r\n```\r\n\r\n## 4. Proof-of-Work\r\n\r\nTo implement a distributed timestamp server on a peer-to-peer basis, we will need to use a proof-of-work system similar to Adam Back's Hashcash [^6], rather than newspaper or Usenet posts. The proof-of-work involves scanning for a value that when hashed, such as with SHA-256, the hash begins with a number of zero bits. The average work required is exponential in the number of zero bits required and can be verified by executing a single hash.\r\n\r\nFor our timestamp network, we implement the proof-of-work by incrementing a nonce in the block until a value is found that gives the block's hash the required zero bits. Once the CPU effort has been expended to make it satisfy the proof-of-work, the block cannot be changed without redoing the work. As later blocks are chained after it, the work to change the block would include redoing all the blocks after it.\r\n\r\n```\r\n       ┌────────────────────────────────────────┐      ┌────────────────────────────────────────┐\r\n       │  Block                                 │      │  Block                                 │\r\n       │  ┌──────────────────┐ ┌──────────────┐ │      │  ┌──────────────────┐ ┌──────────────┐ │\r\n───────┼─►│ Prev Hash        │ │ Nonce        │ ├──────┼─►│ Prev Hash        │ │ Nonce        │ │\r\n       │  └──────────────────┘ └──────────────┘ │      │  └──────────────────┘ └──────────────┘ │\r\n       │                                        │      │                                        │\r\n       │ ┌──────────┐ ┌──────────┐ ┌──────────┐ │      │ ┌──────────┐ ┌──────────┐ ┌──────────┐ │\r\n       │ │ Tx       │ │ Tx       │ │ ...      │ │      │ │ Tx       │ │ Tx       │ │ ...      │ │\r\n       │ └──────────┘ └──────────┘ └──────────┘ │      │ └──────────┘ └──────────┘ └──────────┘ │\r\n       │                                        │      │                                        │\r\n       └────────────────────────────────────────┘      └────────────────────────────────────────┘\r\n```\r\n\r\nThe proof-of-work also solves the problem of determining representation in majority decision making. If the majority were based on one-IP-address-one-vote, it could be subverted by anyone able to allocate many IPs. Proof-of-work is essentially one-CPU-one-vote. The majority decision is represented by the longest chain, which has the greatest proof-of-work effort invested in it. If a majority of CPU power is controlled by honest nodes, the honest chain will grow the fastest and outpace any competing chains. To modify a past block, an attacker would have to redo the proof-of-work of the block and all blocks after it and then catch up with and surpass the work of the honest nodes. We will show later that the probability of a slower attacker catching up diminishes exponentially as subsequent blocks are added.\r\n\r\nTo compensate for increasing hardware speed and varying interest in running nodes over time, the proof-of-work difficulty is determined by a moving average targeting an average number of blocks per hour. If they're generated too fast, the difficulty increases.\r\n\r\n## 5. Network\r\n\r\nThe steps to run the network are as follows:\r\n\r\n1. New transactions are broadcast to all nodes.\r\n2. Each node collects new transactions into a block.\r\n3. Each node works on finding a difficult proof-of-work for its block.\r\n4. When a node finds a proof-of-work, it broadcasts the block to all nodes.\r\n5. Nodes accept the block only if all transactions in it are valid and not already spent.\r\n6. Nodes express their acceptance of the block by working on creating the next block in the chain, using the hash of the accepted block as the previous hash.\r\n\r\nNodes always consider the longest chain to be the correct one and will keep working on extending it. If two nodes broadcast different versions of the next block simultaneously, some nodes may receive one or the other first. In that case, they work on the first one they received, but save the other branch in case it becomes longer. The tie will be broken when the next proof-of-work is found and one branch becomes longer; the nodes that were working on the other branch will then switch to the longer one.\r\n\r\nNew transaction broadcasts do not necessarily need to reach all nodes. As long as they reach many nodes, they will get into a block before long. Block broadcasts are also tolerant of dropped messages. If a node does not receive a block, it will request it when it receives the next block and realizes it missed one.\r\n\r\n## 6. Incentive\r\n\r\nBy convention, the first transaction in a block is a special transaction that starts a new coin owned by the creator of the block. This adds an incentive for nodes to support the network, and provides a way to initially distribute coins into circulation, since there is no central authority to issue them. The steady addition of a constant of amount of new coins is analogous to gold miners expending resources to add gold to circulation. In our case, it is CPU time and electricity that is expended.\r\n\r\nThe incentive can also be funded with transaction fees. If the output value of a transaction is less than its input value, the difference is a transaction fee that is added to the incentive value of the block containing the transaction. Once a predetermined number of coins have entered circulation, the incentive can transition entirely to transaction fees and be completely inflation free.\r\n\r\nThe incentive may help encourage nodes to stay honest. If a greedy attacker is able to assemble more CPU power than all the honest nodes, he would have to choose between using it to defraud people by stealing back his payments, or using it to generate new coins. He ought to find it more profitable to play by the rules, such rules that favour him with more new coins than everyone else combined, than to undermine the system and the validity of his own wealth.\r\n\r\n## 7. Reclaiming Disk Space\r\n\r\nOnce the latest transaction in a coin is buried under enough blocks, the spent transactions before it can be discarded to save disk space. To facilitate this without breaking the block's hash, transactions are hashed in a Merkle Tree [^7] [^2] [^5], with only the root included in the block's hash. Old blocks can then be compacted by stubbing off branches of the tree. The interior hashes do not need to be stored.\r\n\r\n```\r\n┌──────────────────────────────────────────┐    ┌──────────────────────────────────────────┐\r\n│                                          │    │                                          │\r\n│ Block ┌─────────────────────────────┐    │    │ Block ┌─────────────────────────────┐    │\r\n│       │  Block Header (Block Hash)  │    │    │       │  Block Header (Block Hash)  │    │\r\n│       │ ┌────────────┐ ┌─────────┐  │    │    │       │ ┌────────────┐ ┌─────────┐  │    │\r\n│       │ │ Prev Hash  │ │ Nonce   │  │    │    │       │ │ Prev Hash  │ │ Nonce   │  │    │\r\n│       │ └────────────┘ └─────────┘  │    │    │       │ └────────────┘ └─────────┘  │    │\r\n│       │                             │    │    │       │                             │    │\r\n│       │     ┌─────────────┐         │    │    │       │     ┌─────────────┐         │    │\r\n│       │     │  Root Hash  │         │    │    │       │     │  Root Hash  │         │    │\r\n│       │     └─────▲─▲─────┘         │    │    │       │     └─────▲─▲─────┘         │    │\r\n│       │           │ │               │    │    │       │           │ │               │    │\r\n│       │           │ │               │    │    │       │           │ │               │    │\r\n│       └───────────┼─┼───────────────┘    │    │       └───────────┼─┼───────────────┘    │\r\n│                   │ │                    │    │                   │ │                    │\r\n│     ..........    │ │     ..........     │    │     ┌────────┐    │ │     ..........     │\r\n│     .        ─────┘ └─────.        .     │    │     │        ├────┘ └─────.        .     │\r\n│     .

If we suppose blocks are generated every 10 minutes, 80 bytes * 6 * 24 * 365 = 4.2MB per year. With computer systems typically selling with 2GB of RAM as of 2008, and Moore's Law predicting current growth of 1.2GB per year, storage should not be a problem even if the block headers must be kept in memory.\r\n\r\n## 8. Simplified Payment Verification\r\n\r\nIt is possible to verify payments without running a full network node. A user only needs to keep a copy of the block headers of the longest proof-of-work chain, which he can get by querying network nodes until he's convinced he has the longest chain, and obtain the Merkle branch linking the transaction to the block it's timestamped in. He can't check the transaction for himself, but by linking it to a place in the chain, he can see that a network node has accepted it, and blocks added after it further confirm the network has accepted it.\r\n\r\n```\r\n     Longest Proof-of-Work Chain\r\n        ┌────────────────────────────────────────┐      ┌────────────────────────────────────────┐       ┌────────────────────────────────────────┐\r\n        │   Block Header                         │      │   Block Header                         │       │   Block Header                         │\r\n        │  ┌──────────────────┐ ┌──────────────┐ │      │  ┌──────────────────┐ ┌──────────────┐ │       │  ┌──────────────────┐ ┌──────────────┐ │\r\n ───────┼─►│ Prev Hash        │ │ Nonce        │ ├──────┼─►│ Prev Hash        │ │ Nonce        │ ├───────┼─►│ Prev Hash        │ │ Nonce        │ ├────────►\r\n        │  └──────────────────┘ └──────────────┘ │      │  └──────────────────┘ └──────────────┘ │       │  └──────────────────┘ └──────────────┘ │\r\n        │                                        │      │                                        │       │                                        │\r\n        │     ┌───────────────────┐              │      │    ┌────────────────────┐              │       │     ┌───────────────────┐              │\r\n        │     │   Merkle Root     │              │      │    │   Merkle Root      │              │       │     │   Merkle Root     │              │\r\n        │     └───────────────────┘              │      │    └────────▲─▲─────────┘              │       │     └───────────────────┘              │\r\n        │                                        │      │             │ │                        │       │                                        │\r\n        └────────────────────────────────────────┘      └─────────────┼─┼────────────────────────┘       └────────────────────────────────────────┘\r\n                                                                      │ │\r\n                                                                      │ │\r\n                                                        ┌────────┐    │ │     ..........\r\n                                                        │        ├────┘ └─────.        .\r\n                                                        │ Hash01 │            .

While network nodes can verify transactions for themselves, the simplified method can be fooled by an attacker's fabricated transactions for as long as the attacker can continue to overpower the network. One strategy to protect against this would be to accept alerts from network nodes when they detect an invalid block, prompting the user's software to download the full block and alerted transactions to confirm the inconsistency. Businesses that receive frequent payments will probably still want to run their own nodes for more independent security and quicker verification.\r\n\r\n## 9. Combining and Splitting Value\r\n\r\nAlthough it would be possible to handle coins individually, it would be unwieldy to make a separate transaction for every cent in a transfer. To allow value to be split and combined, transactions contain multiple inputs and outputs. Normally there will be either a single input from a larger previous transaction or multiple inputs combining smaller amounts, and at most two outputs: one for the payment, and one returning the change, if any, back to the sender.\r\n\r\n```\r\n     ┌──────────────────────┐\r\n     │ Transaction          │\r\n     │                      │\r\n     │   ┌─────┐  ┌─────┐   │\r\n─────┼──►│ in  │  │ out │ ──┼─────►\r\n     │   └─────┘  └─────┘   │\r\n     │                      │\r\n     │                      │\r\n     │   ┌─────┐  ┌─────┐   │\r\n─────┼──►│ in  │  │ ... │ ──┼─────►\r\n     │   └─────┘  └─────┘   │\r\n     │                      │\r\n     │                      │\r\n     │   ┌─────┐            │\r\n─────┼──►│...  │            │\r\n     │   └─────┘            │\r\n     │                      │\r\n     └──────────────────────┘\r\n```\r\nIt should be noted that fan-out, where a transaction depends on several transactions, and those transactions depend on many more, is not a problem here. There is never the need to extract a complete standalone copy of a transaction's history.\r\n\r\n## 10. Privacy\r\n\r\nThe traditional banking model achieves a level of privacy by limiting access to information to the parties involved and the trusted third party. The necessity to announce all transactions publicly precludes this method, but privacy can still be maintained by breaking the flow of information in another place: by keeping public keys anonymous. The public can see that someone is sending an amount to someone else, but without information linking the transaction to anyone. This is similar to the level of information released by stock exchanges, where the time and size of individual trades, the \"tape\", is made public, but without telling who the parties were.\r\n\r\n```\r\nTraditional Privacy Models                                                │\r\n                                      ┌─────────────┐   ┌──────────────┐  │  ┌────────┐\r\n┌──────────────┐  ┌──────────────┐    │  Trusted    │   │              │  │  │        │\r\n│  Identities  ├──┤ Transactions ├───►│ Third Party ├──►│ Counterparty │  │  │ Public │\r\n└──────────────┘  └──────────────┘    │             │   │              │  │  │        │\r\n                                      └─────────────┘   └──────────────┘  │  └────────┘\r\n                                                                          │\r\n\r\nNew Privacy Model\r\n                                       ┌────────┐\r\n┌──────────────┐ │ ┌──────────────┐    │        │\r\n│  Identities  │ │ │ Transactions ├───►│ Public │\r\n└──────────────┘ │ └──────────────┘    │        │\r\n                                       └────────┘\r\n```\r\nAs an additional firewall, a new key pair should be used for each transaction to keep them from being linked to a common owner. Some linking is still unavoidable with multi-input transactions, which necessarily reveal that their inputs were owned by the same owner. The risk is that if the owner of a key is revealed, linking could reveal other transactions that belonged to the same owner.\r\n\r\n## 11. Calculations\r\nWe consider the scenario of an attacker trying to generate an alternate chain faster than the honest chain. Even if this is accomplished, it does not throw the system open to arbitrary changes, such as creating value out of thin air or taking money that never belonged to the attacker. Nodes are not going to accept an invalid transaction as payment, and honest nodes will never accept a block containing them. An attacker can only try to change one of his own transactions to take back money he recently spent.\r\n\r\nThe race between the honest chain and an attacker chain can be characterized as a Binomial Random Walk. The success event is the honest chain being extended by one block, increasing its lead by +1, and the failure event is the attacker's chain being extended by one block, reducing the gap by -1.\r\n\r\nThe probability of an attacker catching up from a given deficit is analogous to a Gambler's Ruin problem. Suppose a gambler with unlimited credit starts at a deficit and plays potentially an infinite number of trials to try to reach breakeven. We can calculate the probability he ever reaches breakeven, or that an attacker ever catches up with the honest chain, as follows [^8]:\r\n\r\n```plaintext\r\np = probability an honest node finds the next block<\r\nq = probability the attacker finds the next block\r\nq = probability the attacker will ever catch up from z blocks behind\r\n``````\r\n     \r\n$$\r\nqz = \r\n\\begin{cases} \r\n1 & \\text{if } p \\leq q \\\\\r\n\\left(\\frac{q}{p}\\right) z & \\text{if } p > q \r\n\\end{cases}\r\n$$\r\n\r\nGiven our assumption that p > q, the probability drops exponentially as the number of blocks the attacker has to catch up with increases. With the odds against him, if he doesn't make a lucky lunge forward early on, his chances become vanishingly small as he falls further behind. \r\n\r\nWe now consider how long the recipient of a new transaction needs to wait before being sufficiently certain the sender can't change the transaction. We assume the sender is an attacker who wants to make the recipient believe he paid him for a while, then switch it to pay back to himself after some time has passed. The receiver will be alerted when that happens, but the sender hopes it will be too late.\r\n\r\nThe receiver generates a new key pair and gives the public key to the sender shortly before signing. This prevents the sender from preparing a chain of blocks ahead of time by working on it continuously until he is lucky enough to get far enough ahead, then executing the transaction at that moment. Once the transaction is sent, the dishonest sender starts working in secret on a parallel chain containing an alternate version of his transaction.\r\n\r\nThe recipient waits until the transaction has been added to a block and z blocks have been linked after it. He doesn't know the exact amount of progress the attacker has made, but assuming the honest blocks took the average expected time per block, the attacker's potential progress will be a Poisson distribution with expected value:\r\n\r\n$$\r\n\\lambda = z\\frac{q}{p}\r\n$$\r\n\r\nTo get the probability the attacker could still catch up now, we multiply the Poisson density for each amount of progress he could have made by the probability he could catch up from that point:\r\n\r\n$$\r\n\\sum_{k=0}^{\\infty} \\frac{\\lambda^k e^{-\\lambda}}{k!} \\cdot \\left\\{ \r\n\\begin{array}{cl} \r\n\\left(\\frac{q}{p}\\right)^{(z-k)} & \\text{if } k \\leq z \\\\\r\n1 & \\text{if } k > z \r\n\\end{array}\r\n\\right.\r\n$$\r\n\r\nRearranging to avoid summing the infinite tail of the distribution...\r\n\r\n$$\r\n1 - \\sum_{k=0}^{z} \\frac{\\lambda^k e^{-\\lambda}}{k!} \\left(1-\\left(\\frac{q}{p}\\right)^{(z-k)}\\right)\r\n$$\r\n\r\nConverting to C code...\r\n\r\n```c\r\n#include <math.h>\r\n\r\ndouble AttackerSuccessProbability(double q, int z)\r\n{\r\n    double p = 1.0 - q;\r\n    double lambda = z * (q / p);\r\n    double sum = 1.0;\r\n    int i, k;\r\n    for (k = 0; k <= z; k++)\r\n    {\r\n        double poisson = exp(-lambda);\r\n        for (i = 1; i <= k; i++)\r\n            poisson *= lambda / i;\r\n        sum -= poisson * (1 - pow(q / p, z - k));\r\n    }\r\n    return sum;\r\n}\r\n```\r\nRunning some results, we can see the probability drop off exponentially with z.\r\n\r\n```plaintext\r\nq=0.1\r\nz=0 P=1.0000000\r\nz=1 P=0.2045873\r\nz=2 P=0.0509779\r\nz=3 P=0.0131722\r\nz=4 P=0.0034552\r\nz=5 P=0.0009137\r\nz=6 P=0.0002428\r\nz=7 P=0.0000647\r\nz=8 P=0.0000173\r\nz=9 P=0.0000046\r\nz=10 P=0.0000012\r\n\r\nq=0.3\r\nz=0 P=1.0000000\r\nz=5 P=0.1773523\r\nz=10 P=0.0416605\r\nz=15 P=0.0101008\r\nz=20 P=0.0024804\r\nz=25 P=0.0006132\r\nz=30 P=0.0001522\r\nz=35 P=0.0000379\r\nz=40 P=0.0000095\r\nz=45 P=0.0000024\r\nz=50 P=0.0000006\r\n```\r\nSolving for P less than 0.1%...\r\n```plaintext\r\nP < 0.001\r\nq=0.10 z=5\r\nq=0.15 z=8\r\nq=0.20 z=11\r\nq=0.25 z=15\r\nq=0.30 z=24\r\nq=0.35 z=41\r\nq=0.40 z=89\r\nq=0.45 z=340\r\n```\r\n## 12. Conclusion\r\nWe have proposed a system for electronic transactions without relying on trust. We started with the usual framework of coins made from digital signatures, which provides strong control of ownership, but is incomplete without a way to prevent double-spending. To solve this, we proposed a peer-to-peer network using proof-of-work to record a public history of transactions that quickly becomes computationally impractical for an attacker to change if honest nodes control a majority of CPU power. The network is robust in its unstructured simplicity. Nodes work all at once with little coordination. They do not need to be identified, since messages are not routed to any particular place and only need to be delivered on a best effort basis. Nodes can leave and rejoin the network at will, accepting the proof-of-work chain as proof of what happened while they were gone. They vote with their CPU power, expressing their acceptance of valid blocks by working on extending them and rejecting invalid blocks by refusing to work on them. Any needed rules and incentives can be enforced with this consensus mechanism.\r\n<br>\r\n\r\n### References\r\n---\r\n[^1]: W. Dai, \"b-money,\" http://www.weidai.com/bmoney.txt, 1998.\r\n[^2]: H.

Only 4.\r\n\r\nThis is weird.\r\n\r\nWe humans are spiritual beings. Rather than just living in a physical world, we also live in the mental worlds we created for each other: stories, music, films, and games. It's in the company of these creations that we get through hard times.\r\n\r\nYet, there are two main problems in the content industry waiting to be solved: distribution and incentivization.\r\n\r\n'Distribution' is how your content reaches its audience. Web2 companies, such as Facebook and TikTok, have solved this quite well, whether through social networks or AI, and they continue to make improvements to their algorithms.\r\n\r\nHowever, 'incentivization' remains an unresolved issue. And this is what Bodhi is built for.\r\n\r\nThe Problem\r\nIncentivization means getting rewards for creating valuable things, whether those rewards are in the form of social approval (views and likes), or financial gain (making money).\r\n\r\nPeople have come up with many ways to make money from their content, like adding sponsorships and selling merchandise in it.\r\n\r\nThese approaches create a higher barrier, as it requires content creators to be not just creators, but also businessmen.\r\n\r\nSo, what about ads or paywall, aren't they good enough?\r\n\r\nLet's consider pornography as an example, due to its universal and easily measurable value. If people can’t make money even from porn, it means our current approach is fundamentally flawed.\r\n\r\nBefore Onlyfans, creators on Pornhub earned just $0.6 per 1000 views.\r\n\r\nWhy so low? Because advertisers didn't want to place ads on porn sites. That's one of the problems of ads -- advertisers select content and audiences. Value to viewers doesn’t always mean value to advertisers.\r\n\r\nLater with the subscription-based Onlyfans, creators' income significantly increased.\r\n\r\nHowever, Onlyfans is not the perfect solution, either. Understanding the limitations of Onlyfans is the key to grasping the problem of content incentivization.\r\n\r\nThe problem with Onlyfans is: it reduces the value that content creates for the world.\r\n\r\nOn Pornhub, your content could be consumed by 100,000 people, creating significant value, but yielding minimal return for you.\r\nOn Onlyfans, you might have 100 subscribers paying $9.9 each per month, which increases your income. But the catch is that, the overall ‘cake’ shrinks – only 100 people see your content, reducing the value it adds to the world.\r\nGetting a larger slice of a smaller cake will never be the ultimate solution. The ideal approach should be enlarging the cake and capturing a fair share of it.\r\n\r\nDig Deeper\r\nBehind this problem lies a deeper issue:\r\n\r\nCopying information is cost-free, yet our economic system isn't built for goods with zero marginal cost.\r\n\r\nConsider the example of an apple sale: If I sell you an apple for one dollar, I lose an apple but gain a dollar, and you lose a dollar but gain an apple. This is what our economic system was designed for— the exchange of physical goods.\r\n\r\nHowever, the scenario changes when trading information (like articles, music, videos). Information can be replicated endlessly. In such exchanges, a finite valuable resource (money) is traded for something that can be infinitely duplicated at no cost.\r\n\r\nThis creates an inherent conflict, which is the root of many problems: piracy, the challenge of rewarding creators, and the “shrinking cake” dilemma mentioned earlier.\r\n\r\nA New Path\r\nWith crypto, the solution space for the incentivization problem expand. A trading model distinct from “buying” could be devised, tackling the issues that traditional economic systems cannot.\r\n\r\nBy establishing such a model at a fundamental level (a protocol), applications and users can concentrate on their core work without worrying about incentivization.\r\n\r\nLet's return to the problem we aim to solve: incentivizing valuable content.\r\n\r\nThis problem can be broken down into two sub-questions:\r\n\r\nHow to Recognize the Value of Content\r\nHow to Provide Incentives\r\nHow to Recognize the Value of Content\r\nOne thing is certain: we cannot measure the value of content by the content itself. The value of content is determined by its consumers.\r\n\r\nThe same article may seem pointless to one reader but could be a million-dollar inspiration to another; a how to video might be trivial to one viewer but crucial to another.\r\n\r\nThis is similar to search engines. The value of a page is not about how often keywords appear, but how many other pages refer to it.\r\n\r\nThus we can conclude:\r\n\r\nThe protocol doesn’t need to know what the content is. It measures value through consumer behavior.\r\n\r\nHow to Provide Incentives\r\nFirst, let’s consider what won’t work under a crypto protocol:\r\n\r\nAny paywall (pay to view) is infeasible.\r\n\r\nWhy is this the case?\r\n\r\nWhen you build an economic mechanism on the blockchain that runs perpetually, where should its corresponding content be stored?\r\n\r\nIf it's in a centralized server, it means it could disappear or become invalid at any time, rendering the economic mechanism meaningless. It's like investing in a company whose products and itself could vanish from the earth at any time, which doesn’t make sense.\r\n\r\nInstead, content should be in a place that is permanently accessible, i.e., on the blockchain. Blockchains like Arweave, designed for storage, can accomplish this task well.\r\n\r\nHowever, content on the blockchain is inevitably public.\r\n\r\nIf you want to add a paywall for a public thing, you have to encrypt it. But where does the decryption process take place? If it's managed by a centralized server, its failure means the content becomes invalid, no different from direct hosting on a centralized server. If it's decrypted through blockchain mechanisms, it essentially remains public.\r\n\r\nSo, the “paywall” is not only inefficient economically, but also infeasible technically.\r\n\r\nBy the way, when we examine content on the blockchain, we find it has two characteristics: anyone can access it (non-excludability), and your access doesn’t affect others’ access (non-rivalry).\r\n\r\nThis is exactly the definition of public goods. That's why the content incentivization problem is so challenging, as it is fundamentally a public goods funding problem, a dilemma that humanity has struggled with for thousands of years.\r\n\r\nBodhi as an experiment\r\nBodhi is an experiment to solve the problem of content incentivization.\r\n\r\nInstead of relying on ads or paywall, Bodhi turns anything you create into an asset, like a mini-company.\r\n\r\nPeople can buy and sell its shares directly with Bodhi. Share prices automatically increase when people buy, and decrease when they sell.\r\n\r\nAs the creator, you own the initial share and profit as its value increases.\r\n\r\nPlus, every time someone trades shares of your content, you receive a portion of the transaction as a fee.\r\n\r\nFrom a technical perspective, Bodhi stores content on Arweave, turning each Arweave ID into an ERC1155 asset. As users purchase, the token is minted more, and its price follows a quadratic curve based on the supply volume.\r\n\r\nFrom a financial perspective, Bodhi provides liquidity to long-tail assets. Since the protocol acts as the trading counterparty, liquidity is maintained even when there's only a single buyer for an asset.\r\n\r\nWhere does Bodhi come from\r\nI've had the idea for many years, but my confidence in it came from a sudden realization:\r\n\r\nFor the toughest problems, the answers may not lie in entities, but in the void (in our minds).\r\n\r\nThings that exist only in our minds are often the most influential and vibrant. This is the greatness of Bitcoin, which isn't always easy to recognize.\r\n\r\nMoreover, people often think of Meme and Ponzi as insignificant or even evil. But the two have one thing in common: they exist only in our minds and can be very powerful incentives for human beings. My intuition tells me Meme and Ponzi are underrated and might hold the key to public goods funding problem.\r\n\r\nBodhi embodies this very insight.\r\n\r\nFuture\r\nAs an experiment, even if Bodhi doesn't work as expected, it will still offer valuable insights for future protocols.\r\n\r\nBut if it works, we will unlock a lot of interesting stuff.\r\n\r\nSince Bodhi has no protocol fee, anyone can build any type of protocol on top of it, and charge a fee if they want.\r\n\r\nHere're some possible ones:\r\n\r\nA Youtube/TikTok-like platform with Bodhi\r\nA book publishing protocol with Bodhi\r\nA Steam-like game publishing protocol with Bodhi\r\nA protocol version of Twitter/Medium with Bodhi\r\nA crowdfunding tool for communities with Bodhi\r\nAn academic paper publishing and fundraising protocol with Bodhi\r\nA voting protocol with Bodhi (sounds funny because bribery is inherently built-in.)\r\nA protocol version of Github where open source code can be both stored and incentivized\r\n...\r\n\r\nNow that you have a general understanding of what Bodhi is, to give you a deeper experience of it, this post itself is the very first asset on Bodhi.\r\n\r\nTry trading it.","creator":"0x1f19f395cd1c3fecbb10fea1533153055471175f","if_to_text_assets_k_v":true,"likes":0,"tags":{},"author_true":"0x1f19f395cd1c3fecbb10fea1533153055471175f","space_contract_addr":"0x0","share_holders":[]},{"id":68,"created_at":"2023-12-17T15:07:04.585939+00:00","id_on_chain":273,"content":"\r\n**Enter Bodhi: A Novel Approach**\r\n\r\n***Bodhi*** emerges as an experimental solution to the content incentivization conundrum.

It measures value through consumer behavior.**\r\n\r\n### How to Provide Incentives\r\n\r\nFirst, let’s consider what won’t work under a crypto protocol:  \r\n\r\n**Any paywall (pay to view) is infeasible.** \r\n\r\nWhy is this the case?\r\n\r\nWhen you build an economic mechanism on the blockchain that runs perpetually, where should its corresponding content be stored?\r\n\r\nIf it's in a centralized server, it means it could disappear or become invalid at any time, rendering the economic mechanism meaningless. It's like investing in a company whose products and itself could vanish from the earth at any time, which doesn’t make sense.\r\n\r\nInstead, content should be in a place that is permanently accessible, i.e., on the blockchain. Blockchains like Arweave, designed for storage, can accomplish this task well.\r\n\r\nHowever, content on the blockchain is inevitably public.\r\n\r\nIf you want to add a paywall for a public thing, you have to encrypt it. But where does the decryption process take place? If it's managed by a centralized server, its failure means the content becomes invalid, no different from direct hosting on a centralized server. If it's decrypted through blockchain mechanisms, it essentially remains public.\r\n\r\nSo, the “paywall” is not only inefficient economically, but also infeasible technically.\r\n\r\nBy the way, when we examine content on the blockchain, we find it has two characteristics: anyone can access it (non-excludability), and your access doesn’t affect others’ access (non-rivalry).\r\n\r\nThis is exactly the definition of public goods. That's why the content incentivization problem is so challenging, as **it is fundamentally a public goods funding problem**, a dilemma that humanity has struggled with for thousands of years.\r\n\r\n## Bodhi as an experiment\r\n\r\nBodhi is an experiment to solve the problem of content incentivization.\r\n\r\nInstead of relying on ads or paywall, **Bodhi turns anything you create into an asset, like a mini-company**.\r\n\r\nPeople can buy and sell its shares directly with Bodhi. Share prices automatically increase when people buy, and decrease when they sell.\r\n\r\nAs the creator, you own the initial share and profit as its value increases.\r\n\r\nPlus, every time someone trades shares of your content, you receive a portion of the transaction as a fee.\r\n\r\nFrom a technical perspective, Bodhi stores content on Arweave, turning each Arweave ID into an ERC1155 asset. As users purchase, the token is minted more, and its price follows a quadratic curve based on the supply volume.\r\n\r\nFrom a financial perspective, Bodhi provides liquidity to long-tail assets. Since the protocol acts as the trading counterparty, liquidity is maintained even when there's only a single buyer for an asset.\r\n\r\n### Where does Bodhi come from\r\n\r\nI've had the idea for many years, but my confidence in it came from a sudden realization:\r\n\r\n> For the toughest problems, the answers may not lie in entities, but in the void (in our minds).\r\n\r\nThings that exist only in our minds are often the most influential and vibrant. This is the greatness of Bitcoin, which isn't always easy to recognize.\r\n\r\nMoreover, people often think of Meme and Ponzi as insignificant or even evil. But the two have one thing in common: they exist only in our minds and can be very powerful incentives for human beings. My intuition tells me Meme and Ponzi are underrated and might hold the key to public goods funding problem.\r\n\r\nBodhi embodies this very insight.\r\n\r\n## Future\r\n\r\nAs an experiment, even if Bodhi doesn't work as expected, it will still offer valuable insights for future protocols.\r\n\r\nBut if it works, we will unlock a lot of interesting stuff.\r\n\r\nSince Bodhi has no protocol fee, anyone can build any type of protocol on top of it, and charge a fee if they want.\r\n\r\nHere're some possible ones:\r\n\r\n- A Youtube/TikTok-like platform with Bodhi\r\n- A book publishing protocol with Bodhi\r\n- A Steam-like game publishing protocol with Bodhi\r\n- A protocol version of Twitter/Medium with Bodhi\r\n- A crowdfunding tool for communities with Bodhi\r\n- An academic paper publishing and fundraising protocol with Bodhi\r\n- A voting protocol with Bodhi (sounds funny because bribery is inherently built-in.)\r\n- A protocol version of Github where open source code can be both stored and incentivized\r\n\r\n...\r\n\r\nNow that you have a general understanding of what Bodhi is, to give you a deeper experience of it, this post itself is the very first asset on Bodhi.\r\n\r\n**Try trading it.**","creator":"0xd10be77ad727ce32c85809a2ae8ff4d86ebc068d","if_to_text_assets_k_v":true,"likes":0,"tags":{},"author_true":"0xd10be77ad727ce32c85809a2ae8ff4d86ebc068d","space_contract_addr":"0x0","share_holders":[]}]
