The Ethereum client team is testing an optional fast confirmation mechanism that aims to reduce the waiting time for some Layer 2 networks and exchanges to confirm mainnet deposits to about 13 seconds. Developers state that this rule can be adopted without a hard fork, although integration work with clients and APIs is still ongoing. The client team has begun implementation, and once deployed, nodes can start using this rule without the need for coordination across the entire network. Exchanges, Layer 2 networks, and infrastructure providers are expected to require minimal adjustments to integrate this feature.
How FCR Works
Instead of relying on block numbers, FCR determines whether a block can be considered confirmed by assessing the confirmations from validators, thereby addressing the slow bridging issue. “When a node detects that more security is needed, it will wait longer to quickly confirm a block. This is a feature, not a bug,” Ma stated.
