Ethereum co-founder Vitalik Buterin has proposed the Fast Confirmation Rule (FCR) to significantly reduce Ethereum deposit confirmation times from the current 2–13 minutes to approximately 13 seconds. This protocol change aims to enhance user experience by providing an earlier confirmation signal based on validator attestations, without requiring a hard fork. While FCR does not replace Ethereum's full finality process, it offers a faster confirmation option under favorable network conditions. The proposal has sparked debate within the Ethereum community, with critics highlighting concerns about validator concentration and the reliance on validator honesty and low latency. Despite these concerns, FCR is seen as a step towards improving transaction efficiency on the Ethereum network. The initiative is part of a broader roadmap, Lean Ethereum, which aims to enhance Ethereum's resilience and throughput while maintaining security.
