Credential sharing history logs track when, where, and to whom users share their verifiable credentials (VCs). These immutable records, stored on blockchain or decentralized storage, include metadata like recipient DID, timestamp, and purpose (e.g., "age verification for alcohol purchase"). Users can audit logs via dashboards to detect unauthorized sharing, while issuers use them for compliance reporting. Privacy-preserving techniques like zero-knowledge proofs ensure log details remain confidential unless explicitly authorized.
