Identity networks address memorabilia authentication by issuing digital certificates linked to physical items via NFC/RFID tags or QR codes. Blockchain records provenance, ownership history, and expert appraisals. Verifiable credentials (VCs) for collectors prove legitimacy without exposing sensitive data. AI compares digital scans with certified templates, while decentralized identifiers (DIDs) ensure tamper-proof records. Interoperable standards enable global verification across auction houses, museums, and online marketplaces.
