精通区块链(第2版影印版)

区块链是一种分布式账簿，可以跨多个节点进行复制，同时保持事务的不可变性、透明性以及加密安全存储。区块链技术是加密货币的支柱，它在金融、政府、媒体和几乎所有其他行业都有应用。本书的第二版经过了有效的更新和修订，详细描述了这一靠前技术及其在现实世界中的实现。本书从区块链的技术基础入手，讲述了分布式系统的基础知识、加密技术以及如何保护数据安全。你将学习到加密货币背后的机制以及如何使用以太坊（Ethereum）这一去中心化虚拟机开发应用程序。你还将探究其他区块链解决方案，了解Hyperledger下的业务区块链框架，这是一项由Linux基金会主持的、旨在推动区块链技术的协力成果。你也会看到如何实现除货币外的区块链解决方案、带区块链的物联网、区块链可扩展性以及这种引人入胜的强大技术的远景。
