ChainCatcher news, ZK technology developer=nil; Foundation announces the launch of a new Type-1 zkEVM, powered by zkLLVM, aimed at enhancing the security of Ethereum scaling. The zkEVM V1 is now open to the public, including a prototype codebase, specifications, and related blog posts.=nil; Utilizing zkLLVM to automatically compile high-level code (such as C++ or Rust) into efficient zk-SNARK circuits, this automated compilation method contrasts with the traditional manual circuit definition approach. =nil; Key features of zkEVM include auditability (the C++ compiled circuit approach is more feasible and cost-effective, making it easier to audit); upgradability (changes to the EVM can easily and automatically recompile the circuit); compatibility (Type-1 bytecode is closest to the C++ version of the Ethereum base execution environment, evmone).According to the crypto data platform RootData, ZK technology developer=nil; Foundation completed a $22 million funding round at a valuation of $220 million in January this year.
