Information encoded in this PCD that is intended to be consumed by the business logic of some application. For example, a type of PCD that could exist is one that is able to prove that its creator knows the prime factorization of a really big number. In that case, the really big number would be the claim, and a ZK proof of its prime factorization would go in the PCD#proof.
Uniquely identifies this instance. Zupass cannot have more than one PCD with the same id. In practice this is often a UUID generated by the PCDPackage#prove function.
A cryptographic or mathematical proof of the PCD#claim.
Refers to PCDPackage#name - each PCD must come from a
particular PCDPackage. By convention, this is a string like
'semaphore-identity-pcd', or 'rsa-ticket-pcd'. These type names
are intended to be globally unique - i.e. no two distinct PCD types
should have the same type name.
Generated using TypeDoc
The EdDSA PCD enables the verification that a specific message has been signed with an EdDSA private key. The EdDSAPCDProof, serving as the signature, is verified using the EdDSAPCDClaim, which consists of the EdDSA public key and the message.
