Berachain Proposes 200ms Preconfirmation Layer for Near-Instant Transactions

23.10.2025 15:24

The Berachain community has introduced a governance proposal, BRIP-0007: Berachain Preconfirmations, aimed at drastically reducing transaction inclusion times from two seconds to approximately 200 milliseconds. This initiative establishes an optional fast lane for users seeking near-instant feedback without altering the network's core consensus design or security guarantees.

The proposal implements a lightweight sequencer that bundles transactions into partial blocks, providing near real-time validation and broadcasting before full settlement occurs through the standard two-second block cycle. This mechanism allows decentralized applications (DApps), such as those in decentralized finance (DeFi) and on-chain gaming, to feel nearly instantaneous, enhancing user engagement and retention by mimicking the responsiveness of traditional Web2 applications.

Security and network stability are maintained through a fallback system; if the sequencer fails, Berachain reverts to its default two-second block building cycle, ensuring consensus integrity. The preconfirmation design mirrors experiments in Ethereum and layer-2 solutions, such as Base's Flashblocks and Primev's recent implementation on Ethereum mainnet, highlighting a broader industry trend toward real-time blockchain experiences. Analysts suggest this could set a new benchmark for high-performance blockchains, potentially accelerating mainstream adoption by reducing perceived latency for traders and gamers.
