The Base L2 network has announced a shift toward a hybrid transaction verification model that combines its current systеm with zero-knowledge (ZK) verification technology. The upgrade is expected to improve security and reduce the time required for final transaction confirmation.

Currently, Base operates using an optimistic rollup model, where transactions are assumed to be valid by default. A dispute window is used to detect and challenge potential errors, which can take several days.

With the introduction of ZK verification, the correctness of computations will be proven through cryptographic proofs. This approach is expected to significantly reduce reliance on long challenge periods and accelerate data processing.

According to developers, the upgrade could reduce transaction finality time to around one day, while also improving the reliability of transfers between Base and the Ethereum mainnet. In addition, fund withdrawals are expected to become more predictable and less dependent on dispute mechanisms.

Within the industry, ZK technologies and zkEVM solutions are increasingly seen as one of the most promising directions for scaling Ethereum. Such implementations allow Layer 2 networks to improve efficiency without compromising security.

The rollout of this new architecture is part of Base’s long-term development strategy aimed at modernizing its infrastructure and improving network performance. The upgrade has already undergone testing, with deployment to the mainnet expected in the near future.
