# zCloak Network By [BmwM5drift](https://paragraph.com/@090000009) · 2023-01-11 --- zCloak Network is a privacy-preserving computing platform based on Substrate. It is designed to provide Zero-Knowledge Proof as a Service for public blockchains. The project was founded in 2020 and is inspired by the Polkadot vision of Web 3.0, which aims to return the sovereign control of personal data to individuals. The zCloak Network offers a range of features and tools that allow users to protect their personal data while taking advantage of the benefits of the blockchain. These include a wallet app/extension, a set of SDKs for zkID login, attribute-based authentication, credential attestation and ZKP verification, and a new computation paradigm built on top of a zk-STARK based virtual machine. The zCloak Network also provides users with a privacy gateway to Web 3.0. It has 30 repositories available on GitHub, and features such as a proof layer, a computation layer, and a storage layer. The proof layer allows users to generate proof instead of raw data presentation, using flexible proof methods such as selective disclosure and ZKP. The computation layer enables users to do computation/analysis of their data in user devices, using social relation and compliance policy as ZK-programs without coding. The storage layer helps to make private data secure and public data authentic and permanent. The zCloak Network also offers a range of identity layer features, such as zkID, a W3C DID and verifiable credential implementation for multi-chain, and W3C DID and W3C verifiable credential. In addition, it provides end-to-end encrypted messaging, as well as a zkID wallet and Arweave permaweb. Overall, the zCloak Network is an innovative project that is designed to provide users with a secure, reliable, and user-friendly platform for protecting their personal data. It offers a range of features, tools, and services that allow users to take advantage of the benefits of the blockchain while keeping their data safe. #DID #zCloak #ZKP #Verifiable Credential --- *Originally published on [BmwM5drift](https://paragraph.com/@090000009/zcloak-network)*
