Abstract: Systems and methods for processing cryptographic transactions within a decentralized node network using region-specific sub-tokenization. A processing system receives transaction requests containing transaction data, including source locations, destination locations, or transaction amounts. The processing system identifies a region corresponding to the provided geolocation data and generates a region-specific sub-token containing metadata related to the transaction. The processing system routes transaction requests to distributed nodes located within the identified region. These nodes locally validate transactions through consensus mechanisms and update region-specific ledgers. The processing system then synchronizes each updated region-specific ledger with a global ledger maintained across the decentralized network for secure, efficient, and verifiable region-specific transaction processing.

Abstract: Systems and methods for securely managing digital assets and generating immutable transaction records linked to decentralized identifiers (DIDs). A processing system operating within a distributed ledger technology (DLT) network receives digital asset transaction requests comprising entity identifiers associated with unique DIDs. The processing system establishes cryptographically secured connections with digital wallets corresponding to these entity identifiers, retrieves digital asset balances from a distributed ledger—including non-transferable cryptographic tokens linked to the DIDs—and executes smart contracts to cryptographically modify digital asset balances. Immutable transaction records comprising timestamps, cryptographic hashes linked to DIDs, and event reference identifiers are generated and stored within the distributed ledger, preserving cryptographic integrity.

Abstract: Systems and methods generating or managing identity-based, non-transferable cryptographic tokens linked to immutable event records. A processing system operating in a distributed ledger technology (DLT) network receives input data including a decentralized identifier (DID) uniquely associated with an entity. The processing system generates a cryptographic token directly linked to the DID and event metadata referencing immutable event records. The processing system encrypts and partitions the event metadata into encrypted data shards and distributes the shards across decentralized storage nodes. A smart contract executed on the DLT network cryptographically links embedded token metadata to encrypted data shards stored in the distributed computing network. The processing system provides authorized access to the encrypted event metadata according to access permissions enforced by the smart contract.

Abstract: Systems and methods for decentralized data storage and retrieval within a distributed computing system include partitioning datasets into encrypted data shards that are each associated with a unique identifier. A processing system operating within the network may distribute these shards across storage nodes selected based on performance metrics such as latency, storage utilization, and reliability. Metadata for each shard, including its identifier, unique cryptographic key, and node location, may be recorded in a tamper-evident distributed ledger. Upon receiving a retrieval request, the system may query the ledger to identify shard locations, retrieve the shards in parallel, validate their integrity by comparing ledger metadata with metadata from storage nodes, decrypt the shards using their respective cryptographic keys, and reconstruct the dataset.

Abstract: Systems and methods for source chain management with identity-based tokens and enhanced security are disclosed. A processing system receives input that includes a decentralized identifier (DID) uniquely associated with an entity. The processing system invokes a smart contract deployed on a distributed ledger to mint a non-transferable identity-based token permanently linked to the DID. Metadata generated for the token includes cryptographic references to a hierarchical source chain structure stored in a decentralized data storage system, along with cryptographic verification data. Events associated with the DID are memorialized by appending granular event details, including timestamps, data changes, and origin identifiers, into the hierarchical source chain.
