zCloak Network

A Zero Knowledge Proof as a service in Polkadot.


zCloak Network is a privacy-preserving computing platform based on Substrate. It enables a new computation paradigm where people can demonstrate that certain data are true without sharing them with a third party. The computation integrity is guaranteed by Zero-Knowledge Proof.

zCloak Space, A general-purpose zk-STARK virtual machine is used for STARK proof generation and verification. It bridges the real-world data to the crypto world e.g. DeFi, DID, Biometric applications without disclosing their privacy.

zCloak Network has won a Web 3.0 foundation grant and has been accepted into the Web3.0 Bootcamp 2021.

Self-Sovereign Data

Regain the sovereign control of your own data. 3rd parties cannot misuse your data if you never share them.

Self-Proving Computation

Run computation/analysis on your data in your own device, not in centralized servers. Use of ZKP to prove the integrity of your computation. Share only the results, not your personal data.

Zero-Knowledge Proof Virtual Machine

Zero-Knowledge Proof VM for general purpose computations. Automatic STARK proof generation/verification for customized computation. No need to hand-write your ZKP circuit anymore.

Zero-Knowledge Proof as a Service

Provide ZKP as a Service for blockchain data privacy applications. Usable for parachains in Polkadot/Kusama and Dapps in major public blockchains including Ethereum, Polygon, BSC, Solana, etc.
