Identity networks address artifact authentication for museums by issuing blockchain-anchored digital certificates linked to physical items via NFC/RFID tags or 3D imaging. Verifiable credentials (VCs) contain cryptographic proofs of provenance, expert appraisals, and ownership history, tied to decentralized identifiers (DIDs). AI compares materials or inscriptions against certified databases, while zero-knowledge proofs validate authenticity without exposing sensitive data. Smart contracts enforce industry standards (e.g., UNESCO guidelines), enabling global verification and combating forgery.
