区块链:从数字货币到信任基石的演进 区块链的起源与设计哲学
Sou Hu Cai Jing· 2025-11-25 14:24
01部分:区块链的起源与设计哲学 会分五篇文章来讲,接下来正文开始,希望大家喜欢,关注我,我是程序猿Tom。 点击上方蓝字 关注我们 1. 传统电子支付的"信任危机"区块链(Blockchain)的诞生并非偶然,它是对现代互联网贸易中长期存 在的"信任成本"的一次深刻反思。在 Satoshi Nakamoto(中本聪) 于 2008 年发表白皮书之前,互联网 贸易"已经变得几乎完全依赖金融机构作为可信任的第三方来处理电子支付" 1。这种中心化模式虽然高 效,但引入了固有的风险和成本,包括交易延迟、中介费用,以及对单一机构的过度信任。 图1. 中本聪纪念像对于 数字货币而言,最大的挑战是如何解决"双重支付"(Double Spending)问题。在缺乏中央权威验证的情 况下,一枚数字文件如何能像实物黄金一样,一旦支付给某人,就无法再被原所有者复制或二次使用? 传统方法依赖银行等第三方机构对交易记录进行时间戳和序列化。而区块链的设计哲学,正是寻求用数 学和分布式计算的确定性,来取代这种对人性或机构的信任。2. 创世纪:比特币白皮书的诞生 (2008)2008 年,署名为 Satoshi Nakamoto(中本聪) ...
