导语
在 Lex Fridman 播客的第 307 期节目中，全球最大加密货币交易所之一 Coinbase 的联合创始人兼 CEO Brian Armstrong（布莱恩·阿姆斯特朗）接受了长达 156 分钟的深度访谈。这次对话录制于美国证券交易委员会（SEC）对 Coinbase 部分上架资产是否属于证券展开调查之前，但其讨论内容超越了短期监管风波，深入探讨了加密货币的本质、创业的艰辛、技术挑战以及科技如何驱动人类进步等根本性问题。作为拥有近亿用户的加密巨头掌舵人，Armstrong 的思考不仅关乎 Coinbase 的未来，也映射了整个加密行业在寻求合规与创新平衡点时所面临的普遍困境与机遇。
摘要
- 创业真谛：行动产生信息。Armstrong 回顾 Coinbase 早期“在迷雾中登山”的经历，强调在找到产品市场匹配（PMF）前，持续行动和快速试错远比空想重要。
- 加密交易所的核心：安全、合规与用户体验的三角平衡。他详细解释了交易所的订单簿机制、防欺诈的机器学习应用以及应对黑客和套利者的“多层铅弹”安全策略。
- 与监管共舞：漫长而必要的道路。Armstrong 承认与政府和监管机构合作是推动加密普及的“漫长而艰难的道路”，但坚信这是构建开放金融系统的必经之路。
- 超越加密：科技向善的实践。他分享了对开放科学平台 ResearchHub 和长寿科技公司 New Limit 的投资逻辑，体现了其利用科技和资本解决重大人类问题的愿景。
- 给年轻一代的建议：成为“竞技场中的人”。他鼓励年轻人通过创建或加入致力于解决实际问题的科技公司来改变世界，而非仅仅停留在批评层面。
从程序员到 CEO：Coinbase 的诞生与至暗时刻
Brian Armstrong（布莱恩·阿姆斯特朗）的编程生涯始于中学时期一本《30 天学会 Java》的书，尽管最初被 Java 的“public static void main”搞得晕头转向，但后来接触的 PHP 和 Ruby 让他找到了快速构建原型的乐趣。这种“黑客”精神在他 2010 年底阅读比特币白皮书后找到了新的用武之地。当时还是 Airbnb 工程师的他，萌生了创建“比特币的 Gmail”——一个托管比特币钱包的想法。
然而，这个想法几乎遭到了所有聪明朋友的反对，要么认为比特币是骗局，要么警告他托管资产会被黑客攻击。在自我怀疑中，Armstrong 利用业余时间用 Ruby 写了一个比特币节点和钱包原型，并申请了 Y Combinator（YC）。YC 的 15 万美元投资成了关键转折点，给了他辞去工作、全力投入的信心。即便如此，公司最初的产品——那个托管钱包——无人问津。在 YC “与客户交谈，改进产品”的训诫下，他联系了早期用户，得到了一个至关重要的反馈：“我没有比特币，所以不知道能用这个钱包做什么。”这一刻，他恍然大悟：用户需要的不是一个存储工具，而是一个能将法币轻松转换为比特币的入口。
于是，团队开始整合银行支付通道，构建基础的交易所功能。当“购买比特币”按钮上线后，用户增长曲线终于开始陡峭上升——他们找到了产品市场匹配。但随之而来的不是坦途，而是作为初创公司 CEO 必须承受的压力测试。
Armstrong 回忆了早期的“至暗时刻”：团队只有五人，所有人严重睡眠不足；网站出现 bug，导致数千名用户在 Reddit 和 Twitter 上愤怒声讨，宣称 Coinbase 完蛋了；客户支持请求积压了两万条；甚至有人把他的手机号公布在网上，导致电话被陌生来电和记者打爆。在一次加班到深夜、试图修复 bug 时，巨大的压力让他一度“蜷缩在地板上哭了一会儿”。但短暂的崩溃后，他爬起来和联合创始人 Fred Ehrsam（弗雷德·埃尔萨姆）一起扛了过去。他总结道，找到合适的联合创始人在这种时刻至关重要，而创业就像“在浓雾笼罩的山脚下登山”，你只能看清前方三四步，必须不断迈步，新的路径才会显现。
交易所如何运作：订单簿、安全与无休止的猫鼠游戏
作为加密货币交易所，Coinbase 的核心功能是撮合买卖双方。Armstrong 将其类比为股票或商品交易所的订单簿机制。当用户点击购买价值 100 美元的比特币时，系统会基于订单簿给出一个报价（包含约 1% 的费用），并在一定时间和价格滑点范围内有效。一旦用户确认，系统便从用户的支付方式（银行卡、银行账户等）扣款，并将相应加密货币记入其账户。
这个看似简单的流程背后，是极其复杂的技术和运营体系：全球各地的支付渠道集成、与不断升级的各种区块链集成、以及最重要的——网络安全和防欺诈。Armstrong 指出，这里没有“银弹”，只有“一堆铅弹”。防御措施包括：严格的代码测试套件、聘请第三方安全公司审计、设立漏洞赏金计划鼓励白帽黑客提前发现漏洞。
在防欺诈方面，机器学习模型扮演了核心角色。Coinbase 会构建标记了欺诈者和正常用户的数据集，将数百甚至数千个特征输入模型以生成风险评分。这些特征包括：设备指纹（例如安装的字体，用于识别虚拟机或模拟器）、“不可能的旅行速度”（通过 IP 地址判断用户是否在极短时间内出现在地理上不可能到达的两个地点）、甚至按键间隔毫秒数（真实用户逐字输入，欺诈者可能直接粘贴整串卡号）。Armstrong 承认这是一场永无止境的“猫鼠游戏”，偶尔的失手和损失也是学习过程的一部分。
除了防御外部攻击，交易所还要应对试图在系统规则内寻找套利机会的“聪明人”。例如，有人会通过 API 程序化地发送数百万次报价请求，寻找定价错误的瞬间并迅速成交。Armstrong 将此视为一种“大型漏洞赏金”，迫使团队必须通过不断实验和优化来完善风控逻辑。
监管、领导力与科技向善的宏大愿景
作为一家在近 100 个国家运营的加密巨头，Coinbase 无法回避监管问题。Armstrong 坦言，与监管机构和政府合作是“一条漫长而艰难的道路”，官僚体系天然抗拒变革。但他认为这是必要的，目标是让全球十亿人能够访问开放的金融系统。2026 年 7 月 SEC 的调查正是这种紧张关系的体现——其初衷是限制欺诈，但也可能抑制创新和个人财务自由。Armstrong 赞赏所有试图厘清这一复杂局面的人，并希望最终个人的利益能够胜出。
谈到作为公众公司 CEO 所面临的舆论压力（包括网络上的大量批评），Armstrong 分享了他的观察。他认为，最好的领导者能够在相信自己所做之事对世界有净正面影响的前提下行动，并不太在意是否会惹恼一部分人。他注意到，像 Mark Zuckerberg（马克·扎克伯格）或 Bill Gates（比尔·盖茨）有时会因显得“公关排练过度”而招致更多不信任，而 Elon Musk（埃隆·马斯克）尽管言论常引发争议，但其“真实性”反而赢得了更多信任。Armstrong 认为，在互联网时代，“真实性”具有溢价，但领导者也需要在真诚表达和避免因言论引发内部或监管问题之间找到平衡。
除了加密货币，Armstrong 还将热情投向了更广泛的“科技向善”领域。他深度参与了两家公司：ResearchHub 和 New Limit。
ResearchHub 旨在挑战传统付费学术期刊体系，建立一个开放的科学交流平台。Armstrong 尖锐地指出，付费期刊是“阻碍全人类知识的骗局”，科学家和资助机构为研究付费，期刊却作为不必要的中间商设置付费墙牟利。ResearchHub 通过社区投票（甚至关联代币奖励）进行“同行评议”，并计划通过建立月度/年度论文排行榜、颁发奖项或资助来重塑科学界的声誉体系，让开放发表成为新的“ prestige”（声望）标准。
New Limit 则是一家专注于细胞重编程和长寿科技的公司。受 Shinya Yamanaka（山中伸弥）获得诺贝尔奖的诱导多能干细胞（iPSC）技术启发，New Limit 的目标是开发能够使细胞和组织“ rejuvenate”（ rejuvenate rejuvenate rejuvenate rejuvenate rejuvenate rejuvenate rejuvenate
