ramework for Decentralized Generative AI on Web3

Abstract

This deposit formalizes a decentralized framework for certifying and archiving AI models, scientific content, and intellectual creations using NFTs and blockchain metadata. It includes a ready-to-use NFT smart contract (ERC-721), structured metadata, digital certificate with SHA256 hash, and a minting interface. The DOI reference is embedded for scientific traceability. All files are timestamped, signed (Anne Povie), and packed for archival or minting purposes. This submission is intended to support researchers, developers, and creators in producing immutable, verifiable scientific artifacts using Web3 infrastructur e.
