Ethereum Launches Fast Confirmation Rules FCR, Deposit Time May Be Shortened to 13 Seconds to Reshape L2 Experience

Gate News: On March 18, Ethereum will introduce the “Fast Confirmation Rule” (FCR), aiming to significantly improve asset transfer efficiency from Layer 1 to Layer 2 networks and related platforms. Julian Ma, a researcher at the Ethereum Foundation, stated that this mechanism is expected to become a universal standard for L2 ecosystems and infrastructure services.

According to disclosures, FCR can reduce deposit confirmation time to about 13 seconds, shortening the current process by approximately 80% to 98%. This optimization mainly addresses the long-standing issue of cross-layer transfer delays, providing users with a near real-time experience when transferring assets to L2 or related platforms.

Technically, FCR introduces the concept of “Fast Confirmation Blocks.” Although these blocks differ from final confirmation blocks, under certain assumptions, they also have a very low reorganization probability, balancing security and efficiency. This mechanism allows the network to achieve higher throughput and lower waiting costs without compromising security.

For different participants, the impact is more direct. L2 networks can reduce the time funds are locked during bridging, lowering overall liquidity costs; infrastructure service providers can offer faster confirmation responses; users will experience faster deposits and smoother operations.

Additionally, the deployment path for FCR is relatively simple, requiring no hard fork upgrades. As consensus layer clients gradually integrate this rule, nodes will automatically execute the relevant logic once enabled, lowering the ecosystem adaptation threshold.

Industry experts believe that this mechanism not only helps optimize cross-layer interactions on Ethereum but may also promote further adoption of L2 scaling solutions. In the context of increasing multi-chain activity and high-frequency trading demands, faster confirmation speeds could become a key factor influencing user choices.
