Holder: deactivate old credentials on issuance #693
Description
Feature Request
Whenever a credential is re-issued to a holder (e.g. after automatic renewal), holder must deactivate the old credential so that only the new credential is used for DCP interactions.
Why Is the Feature Desired?
upon re-issuance, issuers may revoke the old credentials. This is to prevent holders from presentin a revoked credential, and to avoid presenting a potentially out-of-date credential.
Who will sponsor this feature?
Please @-mention the committer that will sponsor your feature.
Solution Proposal
Move the old credential to VcStatus#EXPIRED. Note that moving it to REVOKED could happen automatically, after the next check period of the CredentialWatchdog.
