Vitalik 提议用 Minimmit 替换 Casper FFG,升级以太坊最终性机制

ETH-3,68%

Gate News 消息,3 月 7 日,Vitalik Buterin 今日在 X 平台发文表示,在以太坊共识机制讨论中,正提议将当前的最终性组件 Casper FFG 替换为新的 Minimmit。他指出,Casper FFG 采用两轮最终性机制,验证者需两次签名完成"证明"和"最终确认",而 Minimmit 仅需一轮签名即可完成最终性。作为权衡,Minimmit 的容错阈值将从 Casper FFG 的 33% 降至约 17%。Vitalik 认为,尽管容错比例降低,但 Minimmit 在多种攻击或客户端漏洞场景下,能更大概率让网络进入"多链竞争而非错误最终确认"的状态,这种情况更容易通过社区协调恢复。他表示,相比错误区块被最终确认,短时间内不发生最终性更安全且更具可恢复性,因此认为 Minimmit 在整体安全权衡上可能更优。
