Nash Protocol is an industry blockchain for art traceability and trading based on blockchain technology, providing a full-range solution for the tokenization of art assets. Nash Protocol innovatively introduces NID (Nash Protocol ID) as the unique identity marker for artworks and IAO (Initial Assets Offering) as the technical solutions for the tokenization and issuance of artworks. This ensures that the authentication process during tokenization is genuine, transparent, and immutable, while the issuance and circulation processes are cost-effective, efficient, and trustworthy. This significantly enhances the value of collectibles and reduces costs and risks for issuers and collectors during transactions.
