Vitalik Buterin: @ittaia 我想说，即使 >90% 离线，我们也想要活跃度（如果 >=50% 去拜占庭，那么活跃度显然是不可能的，除非您接受对验证器和客户端都非常严格和脆弱的延迟限制和始终在线的要求）

原推：@ittaia I would say we want liveness even if >90% go offline (liveness if >= 50% go byzantine is obviously impossible unless you accept an extremely strict and fragile latency bound and always-on requirement on both validators and clients)
