Authority Agent

The Authority agent is responsible for managing the connections between User and authorities (i.e. DP, DC) and activities related to Verifiable Credentials/Presentations (i.e. proof requests, validation, issuing). To do so, it includes collaboration between several application components. The Verifiable Credential Generator reads the original evidence record on the DP side to generate and digitally sign the VC. This component is used by the SSI cloud agent, which is also responsible for managing the DID invitations to the User and providing interfaces for the communication between the Agent (cloud or edge) and the Evidence portal or the Ledger necessary to issue or verify VC/VP.
