SIP-7 Credential Revocation

,

As verifiable credentials are issued one needs a way to track if these have been revoked and are thus no longer valid. This strategy described here allows anyone to check if a verifiable credential has been revoked in an efficient and privacy preserving way.

This SIP outlines a mechanism for the revocation of Verifiable Credentials through a new StatusList2021Entry credential status on an issued verifiable credential and a StatusList2021Credential which is a verifiable credential that encapsulates the status list of all Verifiable Credentials issued on the platform.

These will be multiple StatusListCredentials for each <issuer,schema> pairing
