半个月前在迈阿密举办的比特币2022大会，相信大家都有所耳闻。在大会上，著名的计算机科学家、密码学家 Nick Szabo 在演讲时，为我们讲述了比特币发明之前的密码学历史：
$ |" g- d. q- i; H# d; n1 g虽然 1970 年之前的大部分密码学工作主要由军方和间谍机构密码实施，但当 David Chaum 博士在 80 年代发表了关于匿名数字货币和匿名声誉系统的论文后，衍生出了密码学运动，影响了全球上千名密码学家、哲学家和数学家，参与到保护网络时代个人隐私的技术讨论浪潮之中，这些人也被称为“密码朋克”。很显然，密码朋克们拥有着“超前思考”，在当时那个技术不发达的年代就开始研究如何保护人们的隐私，以及如何让通信和支付从物理世界转移到数字世界。 3 m7 H9 h* u- `
所以，萨博将比特币区块链称之为“代表了几十年来密码学、自由和隐私研究的高潮”。 9 Z% L$ u- r8 @
或许大家不知道的是，如今已经代表了区块链的主要特征和编程语言的智能合约一词，最早就是由萨博提出的。
! v6 i1 j( F- v' Z# N简单来说，智能合约就是[以代码的形式写入到计算机中的一种合约或协议，当触发协定条件之时，智能合约会自动执行命令]，当区块链技术诞生后，可扩展、去中心化、不可篡改的属性，天然适合于智能合约的部署。当以太坊区块链首次将智能合约融入到配置之后，这一改变让以太坊成为了当红炸子鸡，智能合约成为了区块链行业的高频词，以智能合约为内核、以区块链为地基的去中心化应用程序如雨后春笋般涌现，让越来越多的区块链爱好者认为，Web3.0 时代即将落地。
. j% t! j$ w9 c然而，如果这些去中心化应用程序大部分依赖于中心化的基础设施，Web3.0 究竟还是不是去中心化的？我们为什么还需要 Web3.0？在不需要考虑隐私的情况下，我们现在 Web2.0 时代的抖音、Twitter、Facebook 用起来不也很方便吗？ # Y( F7 D W/ v8 v
在上期节目中我们也了解过，如今很多去中心化应用程序仍然托管在 Infure、Alchemy 这些服务商之上，这些服务商又依赖亚马逊、谷歌云的中心化服务器，连全球用户超 8000 万的加密钱包 Metamask 本身也只不过是一个通过接入 API 为用户展示链上信息的程序。就好像是“披着 Web3.0 外衣的 Web2.0”。 ' z1 B" @$ E- L8 M
概念先行的 Web3.0，能否真正实现爱好者宣扬的去中心化呢？ & n d4 P6 [7 Y I
欸，还真有这样一种解决方案。 # N1 g! T) S B" H6 i
