Abstract
Apparatus and methods provide an end-to-end system for claiming and sharing non-fungible tokens (“NFTs”). A machine-readable code (“MRC”) may be scanned and validated. Validating the MRC may ensure that instructions encoded in the MRC do not include malware. Validating the MRC may include validating a digital signature encoded in the scanned MRC. Validating the MRC may include locating a record stored on a distributed ledger that corresponds to the scanned MRC. After validating the instructions, processing the encoded instructions may trigger distribution of an NFT to the scanning device. The distributed NFT may be visualized on a webpage or used to gain access to a restricted venue.
