zCloak Network is a privacy-first decentralized identity (DID) and verifiable computation infrastructure. It aims to deliver the Web3 dream of Self-Sovereignty by moving both the storage and the computation of user data from centralized servers to user devices. The integrity of user computation is proven by a STARK-based zero-knowledge virtual machine (ZK-VM) in a browser extension. zCloak's World Wide Web Consortium (W3C) compatible DID system can mirror real-world legal status and reputation in decentralized social networks (DeSoc). With zCloak Network, people can use their real-world data for applications such as decentralized finance (DeFi), identity, and biometrics without compromising their privacy.
