Anonymous Credential Revocation

Definition ∞ Anonymous credential revocation is a system that allows previously issued anonymous digital credentials to be invalidated without revealing the identity of the credential holder. This mechanism ensures that compromised or expired credentials can no longer be utilized. It permits a system to maintain privacy for users while retaining the ability to withdraw their access rights.
Context ∞ Anonymous credential revocation is a key challenge in privacy-preserving digital identity solutions, particularly within decentralized frameworks. Maintaining anonymity while enabling the removal of privileges is crucial for compliance and security in many blockchain applications. Current discussions center on efficient and scalable methods that preserve user privacy while effectively managing credential lifecycle.
