Polygon Zero’s mission is simple: to use zero-knowledge proofs to scale Ethereum to a billion users, without compromising decentralization or security. Achieving this requires fast and efficient proof systems. Today, we’re excited to share Plonky2, a major milestone for zero-knowledge cryptography.
Plonky2 is a recursive SNARK that is 100x faster than existing alternatives and natively compatible with Ethereum. It combines PLONK and FRI for the best of STARKs, with fast proofs and no trusted setup, and the best of SNARKs, with support for recursion and low verification cost on Ethereum.
Plonky2 represents the latest step in Polygon’s ongoing commitment to building the future of Ethereum, and we’re proud to share our work with the Ethereum community.
If zero-knowledge proofs have a superpower, it’s recursion. SNARKs can verify arbitrary computations, and, since verifying a SNARK is a computation, SNARKs can verify other SNARKs.
