Definition ∞ Decentralized revocation is the process of invalidating a digital credential, access right, or token without relying on a single, centralized authority. Control to cancel or nullify is instead distributed across multiple participants or embedded within protocol rules. This mechanism ensures that validity control for digital assets or identities is not concentrated, thereby reducing single points of failure and censorship risks. It is a critical component for maintaining trust and security in distributed systems.
Context ∞ Decentralized revocation is a significant feature in self-sovereign identity (SSI) frameworks and verifiable credential systems built on blockchain technology. News often covers its application in managing digital certificates, licenses, or permissions where a central issuer might be compromised or untrustworthy. Ongoing research addresses the efficiency and privacy implications of broadcasting revocation statuses across various distributed ledgers.
