11.2.2 Issuer

The issuer and user are two roles, and the following APIs are the pre-constraints for issuing credentials. The process of changing the DID user to the issuer does not change the DID Identifier or DID Document, but only the status.

To issue a credential, a DID user needs to register as an issuer and then define a template for registering the credential they want to issue. The credential template will be stored on the chain and everyone can query.
