Abstract

The present invention concerns a method and system for long-term authentication of non-fungible tokens (306, 424). In various embodiments the system (400) includes an off-chain storage system (321) having one or more elements of identifying information (325, 326, 327, 328, 329) for an object (307) including at least one element that authenticates the object. In various embodiments the system (400) further includes a blockchain network adapted for recording a non-fungible token (306) located at a public address (312) on a blockchain (304). In embodiments the minted non-fungible token (306) includes at least an identification manifest (322) and/or a hash (404, 370, 372, 374, 376, 378) of all or part of the elements of identifying information and/or a digital NFT certificate (412) including a digital signature from a certifying authority (414) and the hash (404) of at least one of said elements of identifying information (325, 326, 327, 328, 329) and/or of the identification manifest (322), such that the non-fungible token (306) is independently authenticatable against said certifying authority (414) and/or a corresponding validating authority (416) and/or against the off-chain storage system (321).
