第5章 区块链扩展:扩容、侧链和闪电网络

天下武功唯快不破,因此在互联网时代,很多软件采取的都是先开发一个简化版,然后再快速迭代,这边功能少了就加上,那边功能弱了就补上,数据量大了就增加
存储器,性能不够了就增加服务器,一切看起来似乎都是没什么问题的,扩展嘛,什么纵向扩展、横向扩展,一切跟着需求来,还能给憋住了不成?然而,当这些问
题进入到区块链的场景,情况就有些不那么好对付了,尤其是对于使用广泛、节点众多的系统(如比特币),典型的问题就是由于区块容量限制导致交易确认缓慢,
从而严重制约比特币网络的交易处理能力,而比特币是分布式结构,并不能简单地依靠传统的升级服务器来处理。为了解决这些问题,社区发起了各种讨论,就目前
讨论比较多的解决方案来说,有隔离见证、直接扩容、侧链以及闪电网络。考虑到比特币的问题具有广泛的代表性,因此本章就以比特币为场景来叙述。
