Currently, the proving scheme is utilized by the ZK Badge protocol, which is no longer maintained. It allows users to verify membership in a Data Group from a single Data Source and mint a ZK Badge on an unlinked Ethereum address.
The Hydra-S1 proving scheme allows participants to establish, in one ZK proof, that for a given Proof Identifier:
They own 2 accounts (source and destination)
The source account is part of an
The source account was registered in the with a specific value
A claim about their source account value is true
e.g: "my account value is superior to 5" (non-strict claim)
or "my account value is strictly equal to 5" (strict claim)
They correctly generated a Proof Identifier
