ZKM is a general zero-knowledge proof infrastructure, including zkMIPS (zkVM based on MIPS architecture), Proof Network, etc., aiming to achieve general settlement and de-trustworthy interoperability and promote the liquidity unity of the blockchain ecosystem. zkMIPS is a zero-knowledge proof virtual machine developed by the ZKM team based on a complete MIPS instruction set, realizing the effectiveness of general computing and zero-knowledge proof generation. The Entangled Rollup protocol built on zkMIPS is a set of native asset cross-chain circulation protocols. Typical cases include Metis Hybrid Rollup and GOAT Network.
