前  言
区块链技术源自比特币,是比特币的底层技术。自从2008年一个化名为Satoshi Nakamoto(中文翻译为中本聪)的人发表了一篇论文《比特币: 一种点对点式的电子现金系统》,比特币拉开了极具创新的区块链技术帷幕,让区块链逐渐进入大众视野。2013—2014年,以太坊的概念由程序员出身的Vitalik Buterin提出,其理想在于构建“下一代加密货币与去中心化应用平台”。以太坊首次将智能合约的概念与区块链相结合,并使用区块链为智能合约的执行提供可信的运行环境,使得智能合约的实现成为可能。同时,智能合约的引入,也让区块链的应用场景更加丰富。因此,可以说比特币开辟了区块链,以太坊让区块链有了质的飞跃。
