Vitalik Says New Ethereum Rule Could Cut Confirmations To 12 Seconds
Vitalik Buterin has endorsed a new "fast confirmation rule" (FCR) for Ethereum, which could reduce confirmation times to about 12 seconds. This change provides a strong guarantee that a block will not be reverted, assuming a supermajority of honest validators and network latency under ~3 seconds. While not full economic finality, it offers significant security for many use cases like exchanges, bridges, and Layer-2 systems. The rule, proposed by researcher Julian Ma, cuts deposit times from Ethereum mainnet to L2s and exchanges by 80-98%, drastically improving user experience and operational efficiency. FCR relies on counting attestations rather than block depth, making it faster and provably secure under specific conditions. It can be implemented without a hard fork and includes a fallback to finality if network conditions worsen.
