Vitalik introduces Ethereum's new fast confirmation rules, achieving irreversible guarantees in 12 seconds

Ethereum co-founder Vitalik Buterin published an article introducing a new Ethereum fast confirmation rule mechanism. This mechanism allows users to receive a hard guarantee that Ethereum transactions will not be reverted (Non-revert) after just one Slot (12 seconds). Vitalik pointed out that the security of this rule is based on two premises: first, that the vast majority of validators are honest nodes, and second, that network latency is below approximately 3 seconds. Although its security is slightly lower than economic finality, it already possesses strong reliability for many application scenarios.
