Polygon Zero

Mir is scaling Ethereum with zero-knowledge proofs, the world's fastest ZK scaling technology from Polygon. Mir gathered a team of talented cryptographers and engineers, and after almost two years of work developed the world’s fastest ZK scaling technology. The Mir team is now joining Polygon in order to utilize this groundbreaking technology and build our new project - Polygon Zero, a highly-scalable, Ethereum-compatible ZK Rollup. The Mir team has been quietly working on recursive ZK proofs for almost two years. In 2020, they were the first to implement recursive proofs based on PLONK and Halo. This year, the team set an ambitious goal: sub-second recursive proofs. They built plonky2, a carefully optimized proving system based on PLONK and FRI.
