Abstract
Techniques for authenticating a digital asset represented by an NFT that is stored in a blockchain are disclosed. An NFT that has been minted for an asset is identified. The NFT was minted by generating metadata for the asset and by generating an original hash of the asset. The NFT is stored in a blockchain, and the metadata is stored in a centralized repository. The original hash is stored in either the repository or the blockchain. A potential transfer of the NFT is triggered. Triggering the potential transfer includes downloading, from the centralized repository, a local version of the asset. A local hash of the local version of the asset is generated. The local hash is compared against the original hash. If the two hashes are the same, then the transfer is permitted; otherwise, the transfer is not permitted.
