Coin界 News: Ethereum developer Julian published an article introducing the "Fast Confirmation Rule" (FCR), which will compress the deposit confirmation time from Ethereum L1 to L2 and centralized exchanges from approximately 13 minutes to approximately 13 seconds, a reduction of 80%—98%. It is expected to be implemented and launched by various consensus layer clients in the coming months without requiring a hard fork. Vitalik Buterin commented on this rule, stating that the new fast confirmation rule mechanism can provide hard guarantees after one slot (12 seconds), ensuring that Ethereum will not roll back. The security assumptions of this mechanism are: the vast majority of honest nodes, with network latency below approximately 3 seconds. Although lower than economic finality by one step, it is already sufficiently strong for many use cases.
