Decentralized metadata registry

A computing device comprising:

• a processing device;
• and
• a computer-readable storage medium storing instructions that responsive to execution by the processing device causes the processing device to perform operations including:
• receiving registration data from an originating device, the registration data identifying:
• a cryptographic token;
• metadata describing one or more characteristics associated with entities that receive the cryptographic token;
• and
• access rules to control access to the metadata;
• registering the nonfungible token, the metadata, and the access rules as part of a metadata registry;
• receiving an access request from an originating device, the access request identifying the cryptographic token and requesting access to metadata associated with the cryptographic token;
• determining that access to the metadata is permitted based on the access rule;
• and
• permitting access to the metadata by the originating device responsive to the determining.

A method comprising:

• receiving, by a processing device, registration data via a network from an originating device, the registration data identifying:
• nonfungible tokens (NFT);
• and
• metadata describing one or more characteristics associated with entities that receive the nonfungible tokens, respectively;
• registering, by the processing device, the nonfungible tokens and the metadata in a metadata registry;
• monitoring, by the processing device, access to the metadata and identification of the nonfungible tokens from the metadata registry provided to a plurality of service provider systems;
• and
• generating, by the processing device, a report for communication via the network to the originating device, the report based on the monitored access.
