Abstract
A plurality of metadata entries may be sent from a database system to a distributed storage system via a communication interface. The metadata entries may correspond with a respective plurality of metadata identifiers. A first function in a smart contract deployed on a blockchain may be executed to mint a designated non-fungible token initially owned by a first blockchain party corresponding with a database system account. A first transaction transferring the designated non-fungible token to a second blockchain party different from the first blockchain party may be identified. A second function in the smart contract may be executed to record a second transaction updating an attribute value associated with the designated non-fungible token to include a designated one of the plurality of metadata identifiers corresponding with a designated one of the metadata entries.
