In the verifiable credential (VC) model, an issuer is an entity that creates and signs digital credentials, verifying the holder's attributes. The holder is the individual or organization that possesses and controls these credentials, storing them in a digital wallet. A verifier is responsible for checking the authenticity and validity of the presented credentials, ensuring they meet the required standards. Each role plays a distinct part in the secure and trusted exchange of verifiable credentials.

The system incentivizes sustained activity but has been criticized for favoring users with early access or technical expertise to game rankings.
