Polygon Hermez has announced a significant advancement in its zkEVM technology with the introduction of the zkEVM proof wrapper, implemented using Plonky2 GoldiBear. This development is poised to enhance the efficiency and performance of zkEVM Layer 2 attestations, offering substantial reductions in cost and latency.
The new proof wrapper can aggregate up to 1024 Polygon zkEVM proofs in just 5.2 seconds, setting a new standard for speed in zkEVM Layer 2 proof aggregation. This innovation drastically reduces operational costs, making on-chain proof verification more economical without increasing latency.
Efficiency and Cost Reduction
The Plonky2 GoldiBear implementation eliminates the need for the expensive fflonk wrapping process, resulting in faster proof generation with lower resource consumption. This approach significantly reduces the overall on-chain verification costs by several orders of magnitude, potentially decreasing current latency.
The proof wrapper is generic with respect to the Polynomial Identity Language (PIL) and can be used to wrap other PIL Stark proofs as well. The low computational requirements for both wrapping and aggregation contribute to the reduced costs of zkEVM proofs on-chain verification.
Scalability and Broader Adoption
Faster proof processing enables the handling of larger volumes of zkEVM proofs, facilitating broader adoption of zkEVM-based applications. This improvement supports more frequent attestations, enhancing transaction finality for users.
The integration of the Polygon Hermez zkEVM proof wrapper with Plonky2 GoldiBear into the SNARKtor protocol is expected to streamline operations and further enhance performance efficiencies for zkEVM Layer 2 attestations.
