Ethereum co-founder Vitalik Buterin revealed that the Ethereum community is discussing a potential switch in its finality mechanism from Casper FFG to a new proposal called Minimmit. Unlike Casper FFG, which requires two rounds of signature confirmations, Minimmit achieves block finality with just one round. However, this change reduces the fault tolerance from approximately 33% to 17%. Buterin argues that this trade-off offers better security and recovery capabilities. In the event of an attack or software failure, the system is more likely to experience chain competition rather than erroneous final confirmations, allowing the community more time for coordination and recovery.
