1. 区块链安全性依赖足够数量的节点 2. 但是节点数量增多会导致链上计算和存储的成本成倍上升 3. 而链上计算的目的是为了保证数据从产生时便是真实的，而链下已经逐渐出现其他方式做到这一点 4. 当链下可信计算的成本低于链上时，链上计算便没有意义 5. 执行层与共识层应该彻底解耦，共识层负责去中心化，而执行层只需算得越快越好 6. EVM 是多余的？ 7. 未来只有一个验证者节点负责委托执行层完成计算从而产生「真相」，其他节点只需要单纯验证与保存，防止「真相」被篡改，卧槽，这不是以太坊的大计划？ 8. 所以最终区块链会回归单纯的链上账本，只负责简单的存证与传播。 9. 计算是算盘的事情，关我小本本什么事！

Blockchain Learning Insights: The PoW and related protocols fundamentally resemble an autocratic mechanism, where history is written by the victor. In contrast, protocols based on BFT are more akin to democratic mechanisms, only proposals that receive majority approval have the chance to be recorded.
