Non-Fungible Token (NFT)
token · asset
A token unit whose identifier, commitment, or contract state makes it distinguishable from other units.
A non-fungible token (NFT) is a token record designed to distinguish one unit from another through an ID, commitment, or contract-managed state. "Non-fungible" describes the protocol representation; two NFTs can still be economically equivalent or issued with duplicate media and metadata.
Images, names, traits, and external rights are often stored outside the consensus record and referenced by a URI or content hash. A content-addressed reference can verify bytes, but neither a token nor its metadata alone proves authorship, copyright ownership, authenticity, permanence, or legal entitlement.
NFTs can represent collectibles, tickets, game state, memberships, credentials, receipts, or claims on off-chain assets. Actual control may still depend on issuers, contracts, servers, marketplaces, bridges, custody, or law, and transfer fees and finality depend on the network used.
