Abstract
An example operation may include one or more of connecting, by an identity server, to a blockchain configured to store an identity trait of a user, retrieving, by an identity server, the identity trait from the a blockchain, establishing, by the identity server, a trust group homomorphism digital signature algorithm (DSA) for the user associated with the identity trait based on a public key PK, creating, by the identity server, a zero-knowledge proof function with a public key PKbased on a DSA member of the trust group homomorphism for witness data, providing, by the identity server, the witness data to a challenger for the zero-knowledge proof function, and receiving, by the identity server, a validation of the user as a proved user based on execution of the zero-knowledge proof function based on the witness data.
