Base to Adopt Hybrid Model with ZK Transaction Verification

Base integrates ZK-proofs to enhance security and speed up transaction finalization.

L2 network Base has announced the integration of ZK-proofs from Succinct Labs to enhance security and expedite transaction finalization. 

Base is partnering with Succinct to bring zero-knowledge proofs to Base Azul.

The Coinbase-backed solution plans to integrate zkVM SP1 and a trusted execution environment without abandoning its current optimistic rollup architecture. 

Currently, Base operates on a model where the correctness of a transaction batch is assumed by default. Network participants have several days to challenge potentially incorrect data.

ZK-proofs will allow cryptographic verification of computations without waiting for the challenge period to end.

According to the team, the innovations will:

• speed up finalization to one day;
• reduce reliance on the multi-day challenge window;
• make capital return from the second layer to the main Ethereum network more reliable and independent.

“The larger the network, the greater the need for sustainable infrastructure. Adding ZK-proofs is an important step towards enhancing security and stability,” noted Base head Wilson Kassak.

Succinct described Base’s decision as the largest confirmation to date that the market is beginning to view ZK as a strategic vector for scaling the ecosystem.

This scenario was previously described by Ethereum co-founder Vitalik Buterin, urging the use of zkEVM and cryptographic proofs for block validation. 

The integration fits into Base’s broader strategy: the team is gradually replacing elements of the Optimism stack with its own unified architecture, as reported earlier this year.

Earlier, on April 21, developers of the L2 solution deployed the Azul update in the testnet. The mainnet launch is scheduled for May 13.
