PANews reported on March 18 that Ethereum co-founder Vitalik Buterin shared an article by Ethereum researcher Julian on social media, explaining that a new fast confirmation rule mechanism provides a hard guarantee that Ethereum will not be rolled back after a slot (12 seconds). The security of this mechanism relies on two premises: the honesty of a supermajority of validators and network latency of less than 3 seconds. While this level of guarantee is lower than economic finality, it is already very robust for many application scenarios.
