What is zCloak

zCloak was established in 2020. It offers a privacy-driven computing system on the Polkadot network that uses a zk-STARK machine for multi-dimensional computation.

The zCloak Network uses a zk-STARK based virtual machine for general purpose computations. It can provide Zero-Knowledge Proof as a Service (ZKPaaS) to other parachains in Polkadot/Kusama — serving as a confidential computation infrastructure in the ecosystem.

With zCloak, users can prove their identity has certain attributes or they satisfy certain requirements without showing any private data. The user proofs are made available in major public blockchains by zCloak oracle service. Third-party Dapps can leverage this information to provide personalized service to their users.
