Developers at Polygon Labs have unveiled a concept for a Type 1 prover, enabling EVM networks to integrate zero-knowledge proof (ZKP) based scaling technology.
This solution will allow a wide range of blockchains, including sidechains and Optimistic rollups, to transform into validiums—a specialized form of L2 networks with ZKP—without the need for hard forks.
Unlike ZK-Rollups, which transmit proofs of multiple transactions to the Ethereum network, validiums store only the ZKP on the main chain, while the actual transaction data remains off-chain.
Overall, this is expected to enhance efficiency and reduce transaction costs, according to the developers.
Transitioning to a ZK network could potentially benefit L2 projects by eliminating the seven-day withdrawal delay associated with Optimistic rollup solutions.
The Type 1 prover is anticipated to be released by the end of 2024 and will be included in Polygon’s CDK.
Earlier, Polygon Labs introduced the AggLayer blockchain aggregation layer, scheduled for launch in February.
Back in December 2023, the company’s developers ceased support for Polygon Edge, an early open-source solution for creating EVM networks.
