Vitalik: Ethereum's occasional "loss of finality" does not pose a serious risk

PANews December 10 News, according to Cointelegraph, Vitalik Buterin states that occasional “loss of finality” on Ethereum does not pose a serious risk; the key is to avoid “incorrect finalization.” During this finality delay caused by the Prysm client vulnerability, the chain can still operate normally. Ethereum expert Fabrizio Romano Genovese said that when finality is temporarily lost, Ethereum is more similar to Bitcoin, with its finality being probabilistic; Ethereum’s rule is: when a block receives over 66% validator votes, it becomes “Justified,” and after two more rounds of Epochs (64 blocks), it becomes “Finalized.” He noted that this situation occurred in May 2023. Polygon stated that cross-chain and L2 related transfers will wait for finality, deposits may be delayed, but will not be rolled back or message invalidated.
