Identity networks authenticate manuscripts using decentralized identifiers (DIDs) and verifiable credentials (VCs). Experts issue VCs attesting to a manuscript’s origin, age, and authorship, stored on a blockchain ledger. Zero-knowledge proofs enable privacy-preserving verification (e.g., proving “written by a 15th-century scholar” without revealing sensitive data). Smart contracts cross-check VCs against historical records or expert databases, while cryptographic signatures ensure integrity. Oracles fetch external data (e.g., lab tests for ink dating) to enhance credibility.
