Abstract
A system described herein may maintain a distributed ledger that includes records, such as Non-Fungible Tokens (“NFTs”), which may represent assets dynamic attributes. The system may record a first record, associated with a given asset, to a distributed ledger. The first record may include an identifier, such as an identifier associated with the asset. The system may receive a request to update the attributes of the asset, where the request may include the identifier. The request may include a hash of the previously recorded attributes of the asset, where such attributes may be maintained by an off-chain repository. The system may compare a hash of the attributes, as included in the first record, to the hash included in the request, and may authorize the recordation of a second record to the distributed ledger, including the updated attributes, when the hashes match.
