Systems and methods for creating and managing identity-based tokens linked to immutable event records

A computer-implemented method for generating or managing identity-based, non-transferable cryptographic tokens linked to immutable event records, performed by a processing system operating within a distributed ledger technology (DLT) network, the method comprising:

• receiving from an entity input data that includes a decentralized identifier (DID) associated with the entity;
• generating a cryptographic token directly associated with the DID, wherein the cryptographic token comprises embedded metadata;
• generating event metadata associated with the cryptographic token, wherein the event metadata comprises references identifying event records stored within a distributed computing network and cryptographic provenance data configured to verify authenticity of the event metadata;
• encrypting the event metadata and partitioning the encrypted event metadata into a plurality of encrypted data shards, wherein each encrypted data shard comprises a unique shard identifier;
• distributing each encrypted data shard to decentralized storage nodes selected from the distributed computing network, wherein the distributed computing network comprises a plurality of decentralized storage nodes configured to store or synchronize encrypted data shards;
• deploying a smart contract to the DLT network, wherein the smart contract cryptographically links the metadata embedded within the cryptographic token to references identifying the encrypted data shards stored on the decentralized storage nodes;
• and
• providing, by the processing system via the deployed smart contract, authorized access to the event metadata according to access permissions defined within the smart contract.

A non-transitory processor-readable storage medium having stored thereon processor-executable instructions configured to cause a processing system in a computing device to perform operations for generating or managing identity-based, non-transferable cryptographic tokens linked to immutable event records, the operations comprising:

• receiving from an entity input data that includes a decentralized identifier (DID) associated with the entity;
• generating a cryptographic token directly associated with the DID, wherein the cryptographic token comprises embedded metadata;
