Aleph Zero, a privacy-enhanced public blockchain that runs on the Substrate stack, has announced the launch of zkOS, an EVM-compatible privacy layer that generates zero-knowledge proofs on consumer devices in less than a second. Aleph Zero was developed by Polkadot developer Parity Technologies, and according to the team: "ZkOS allows for private transactions and dApp interactions without leaking the underlying data. ZkOS uses Halo 2 with the promise of KZG to generate proofs faster and provides zkToolkit to simplify integration for developers. According to benchmarks, zkOS can execute proofs in 600-800 milliseconds on a MacBook. ZkOS is designed to be faster, more user-friendly, and to make it easier for developers to integrate into Ethereum applications."
