PANews reported on December 10th, citing Cointelegraph, that Vitalik Buterin stated that Ethereum's occasional "loss of finality" does not pose a serious risk; the key is to avoid "erroneous finality." Despite the finality delay caused by the Prysm client vulnerability, the chain can still function normally. Ethereum expert Fabrizio Romano Genovese stated that when finality is temporarily lost, Ethereum is more like Bitcoin, with its finality being probabilistic. Ethereum's rules are: a block is "Justified" when it receives more than 66% of the validators' votes, and "Finalized" after two more epochs (64 blocks). He pointed out that this situation occurred in May 2023. Polygon stated that cross-chain and L2-related transfers will await finality; deposits may be delayed, but there will be no rollback or message invalidation.
