Ethereum co-founder Vitalik Buterin proposed Fast Confirmation Rules (FCR), aiming to reduce deposit confirmation time to approximately 13 seconds and optimize user experience. FCR provides early confirmation signals through validator attestations without requiring a hard fork. Despite concerns about centralization and honesty, it is still viewed as an important measure to improve network efficiency and is part of the Lean Ethereum roadmap.

Ethereum will introduce the "Fast Confirmation Rules" (FCR) on March 18, enhancing the efficiency of asset transfers from Layer 1 to Layer 2, with confirmation times reduced to approximately 13 seconds. This mechanism is implemented through "fast confirmation blocks," which enhance network throughput and user experience without compromising security, and is expected to drive the adoption of L2 solutions. No hard fork is required, simplifying the deployment process.
