ZK and Non-ZK Reveals
Panther uses zero-knowledge proofs to flip the issue of compliance on its head. Rather than users sharing their personal information with every institution or protocol they interact with, Panther instead allows them for each use case (e.g., one for proof of address, one for identity, etc.) to interact only once with only a single trusted party (a Trust Provider) which can verify their information and issue a signed cryptographic attestation.
Users can then use these attestations to issue an unforgeable mathematical proof, verifiable on- and off-chain, which Service Providers can reference and verify. This indicates that the user has the attributes, credentials, or reputation needed to participate in a transaction, with selective sharing of personal data. The user can make a given Panther Reveal zero-knowledge (carrying no personal data) or non-zk (carrying personal data). Both would be verifiable by anyone if submitted on-chain. Furthermore, zk Reveals are generalizable across other segments such as private identity, insurance, credit scoring, Web3 authentication and other services.
Once a Service Provider (such as a KYC verifier, Institutional DeFi service or Web3 protocol) receives a Panther ZK Reveal, they do not get to learn what the underlying information is, only that the proofs are valid and the users’ claims are true. Also, the Trust Providers who issued the attestations never learn anything about when or how users use those attestations when interacting with Service Providers.
