Vitalik: The occasional "loss of finality" in Ethereum does not pose a serious risk

According to Cointelegraph, Vitalik Buterin stated that Ethereum's occasional "loss of finality" does not pose a serious risk, and the key is to avoid "incorrect finalization." During the finality delay caused by a vulnerability in the Prysm client, the chain can still operate normally.

Ethereum expert Fabrizio Romano Genovese mentioned that when finality is temporarily lost, Ethereum resembles Bitcoin more, as its finality is probabilistic; the rule for Ethereum is that a block is "Justified" when it receives over 66% of validator votes, and it becomes "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 wait for finality, and deposits may be delayed, but there will be no rollbacks or message failures.
