Credential registry service

A credential status registry for Verifiable Credentials (VCs) is a database or service that maintains and verifies the status of Verifiable Credentials that are issued to individuals or entities. It allows issuers or other authorized parties to revoke or suspend VCs that were issued to holders. For example, suspending a driver’s license or revoking a boarding pass.

Enabling the status information for VCs uses a bit string status list, as defined in W3C Draft Specification (https://w3c.github.io/vc-bitstring-status-list/). Bit string status list offers privacy-preserving, space-efficient, and highly performant characteristics.
