较快的技术演进是比特币相对法币的重要优势,也是吸纳竞争币创新,防止被超越的重要保障。一些重大的技术改进会影响交易或区块格式的变化,相对于之前的区块链是一种分叉。改进方式可分为兼容之前版本的软分叉和不兼容前版本的硬分叉。
软分叉的好处是过渡平稳,缺点是为兼容而增加复杂性和技术负担;
硬分叉则更加简洁,但要求全部节点及时更新版本,否则两个版本会产生分出两个链。
修改区块容量限制和隔离见证都是涉及交易和区块格式的重大改进,原本很多人认为可以通过硬分叉实现,但由于以太坊硬分叉造成以太币分裂为ETH和ETC两种币,比特币内部也出现了重市场与重稳定、结算网络方向与主流货币方向的严重分歧,core最终选择了软分叉SW,而core的一些支持者进一步将硬分叉的危害过度渲染,变成了“只能为紧急修复漏洞而被动硬分叉,绝不进行主动硬分叉”的戒律。
这条戒律杜绝了为了提高性能、适应经济或政治形势、吸纳竞争币创新等本应主动采取的硬分叉改进,而只能进行软分叉。
尽管一次软分叉造成的复杂性风险和技术负担并不显著,但连续软分叉所累积的风险和技术负担会呈指数增长。
审时度势,软硬结合的演进路线才是健康的,放弃主动硬分叉相当于自断手脚。
