The Berachain community is rolling out a proposal to reduce transaction ingestion times from 2 seconds to around 200 milliseconds, joining a broader wave of blockchain networks aiming to provide near-instantaneous transaction feedback.
The proposal “BRIP-0007: Berachain Preconfirmations” outlines the implementation of an optional “fast lane” for users seeking speed without compromising the chain's core security guarantees.
This introduces a mechanism where transactions appear confirmed within a second, allowing decentralized finance (DeFi) swaps, on-chain gaming interactions, and other latency-sensitive applications to respond in the same way as traditional Web2 apps.
The proposal states that the preconfirmation layer does not change the network's existing consensus design. Instead, it adds a sequencer that bundles transactions into small “partial blocks” and provides near real-time feedback to wallets and decentralized applications (DApps) before final settlement occurs in the typical 2-second block cycle.

What pre-confirmation brings to Verachain
By introducing a lightweight sequencer that temporarily validates and broadcasts partial transaction data, precheck designs aim to reduce perceived latency.
This means that even if full finality occurs within the original 2-second schedule, the user still sees the transaction within 200 milliseconds.
This development will make decentralized exchanges (DEX) and Web3 games faster and indistinguishable from centralized systems. This allows developers to build applications where swaps, moves, and payments feel instant, even if there is a slight delay in full settlement.
The proposal also focuses on safety and survivability. If the sequencer fails to sync, Berachain simply reverts to the default 2-second block construction cycle, ensuring network stability.

Pre-confirmation on other blockchain networks
Berachain is not the first blockchain to explore the idea of pre-verification. The concept originated in Ethereum research circles, where developers sought to provide “soft confirmation” before transactions are completed on-chain.
Ethereum’s Layer 2 network has been experimenting with similar near-instantaneous inclusion capabilities through shared sequencers and fast lane systems. In July, Base implemented Flashblocks and brought pre-confirmation to mainnet.
On Thursday, pre-confirmation was brought to the Ethereum mainnet through a new remote call procedure (RPC) from the Ethereum infrastructure platform Primev. This allows for faster transfers and smart contract interactions within the mainnet.
