The issuer should have a verifiable data registry publishing component to mirror the verifier's fetching of the verifiable data registry 2. The issuer in my view has a database storing all its subjects' information. It does not have a wallet. 3. Both issuer and verifier should have an audit service to record their issuing/verification of VCs 4. What is the listener role? 5. The issuer may have a verifier component to verify VCs passed to it by a holder e.g. when it swaps input VCs for alternative output VCs Kind regards David Chadwick
