1. A method, comprising:
receiving, by a computing device of a service provider system, data describing a transaction implemented by a service platform of the service provider system for a physical item, initiating minting of a nonfungible token (NFT) describing the physical item as part of a blockchain responsive to the transaction using a fingerprint describing physical characteristics of the physical item generated by scanning the physical item using a physical scanner, generating supplemental digital content based on the NFT describing the physical item, and generating an application for the blockchain, where the application references the NFT and is executable by distributed state machine (DST) nodes of a blockchain system implementing the blockchain to verify that the NFT is owned in a blockchain account of the blockchain, query a location at the service provider system to check availability of the supplemental digital content, and control access to the supplemental digital content based on verifying that the NFT is owned in the blockchain account;
deploying the application for execution by the DST nodes of the blockchain system; and
controlling, by the computing device of the service provider system, output of a badge indicating that ownership of the NFT has been verified in a digital content listing indicating the physical item is available for purchase and/or transfer responsive to verifying that the NFT is owned in the blockchain account, and providing, by the computing device of the service provider system, the supplemental digital content to a client device by exposing the supplemental digital content to the application from the location responsive to the query via a network.
