Foresight News: Risc Zero, a zero-knowledge software developer, has released Zeth, an Ethereum open-source zero-knowledge (ZK) block prover built on RISC Zero zkVM. Zeth can prove the validity of a given Ethereum block within minutes without relying on validators or sync committees. According to Risc Zero, Zeth can be used to help developers more easily build ZK rollups, zkEVM, light clients, and cross-chain bridges. In July, Risc Zero completed a $40 million Series A funding round led by Blockchain Capital.
