A system described herein may identify a chaincode record recorded to a blockchain, and may output chaincode discovery information to a chaincode discovery system. A client device may receive the chaincode discovery information from the chaincode discovery system, and may output a request to invoke the chaincode. The system may obtain verification, from the chaincode discovery system, that the client device is authorized to invoke the chaincode, and may instruct a node that maintains the blockchain to execute the chaincode. The system may receive output values resulting from executing the chaincode and may output, to the client device, the output values resulting from executing the chaincode.

Systems and methods for cross-chain chaincode access and interoperability

A system described herein may maintain a local copy of a distributed ledger, including a first set of records that each include payload information. The system may maintain a restricted access ledger based on the distributed ledger, including a second set of records that include modified payload information included in the first set of records of the distributed ledger. The system may receive a request to access the distributed ledger, including one or more attributes, and may determine, based on the one or more attributes of the request, whether to grant access to the distributed ledger or to the restricted access ledger. When determining to grant access to the distributed ledger, the system may provide payload information from the distributed ledger in response to the request, and when determining to grant restricted access to the restricted access ledger, the system may provide payload information from the restricted access ledger.

Systems and methods for policy-based access to distributed ledger via secure access node

A system described herein may receive ledger information based on contents of a distributed ledger maintained by a first set of nodes, receive communication information associated with the first set of nodes, and establish a second set of nodes. Establishing the second set of nodes may includes providing the ledger information to the second set of nodes, providing the communication information, associated with the first set of nodes, to the second set of nodes, and maintaining information that the second set of nodes are in a first state. After establishing the second set of nodes, the system may obtain sync information from the first set of nodes, provide the sync information to the second set of nodes, and based on providing the sync information to the second set of nodes, maintain information that the second set of nodes are in a second state.

Systems and methods for migration of distributed ledger node environments

A system described herein may maintain a distributed ledger that includes records, such as Non-Fungible Tokens ('NFTs'), which may represent assets dynamic attributes. The system may record a first record, associated with a given asset, to a distributed ledger. The first record may include an identifier, such as an identifier associated with the asset. The system may receive a request to update the attributes of the asset, where the request may include the identifier. The request may include a hash of the previously recorded attributes of the asset, where such attributes may be maintained by an off-chain repository. The system may compare a hash of the attributes, as included in the first record, to the hash included in the request, and may authorize the recordation of a second record to the distributed ledger, including the updated attributes, when the hashes match.

Systems and methods for dynamic asset tokens on a distributed ledger

A system described herein may receive a request for a blockchain network to perform a particular set of operations, such as executing chaincode recorded to a blockchain associated with the blockchain network. The system may receive Key Performance Indicators ('KPIs') of nodes of the blockchain network, and may receive a consensus policy associated with the blockchain network. The consensus policy may indicate a particular quantity of result sets used to verify execution of a given operation by the blockchain network. The system may assign different nodes of the blockchain network to perform different portions of the requested set of operations. The assignments may be determined based on the consensus policy and the KPIs of the nodes. The system may aggregate result sets from different nodes in order to generate aggregated result sets, where the quantity of aggregated result sets satisfies the consensus policy.

Systems and methods for load-balanced chaincode execution and verification in a blockchain network

A system described herein may receive a cross-ledger recordation request that includes an information payload, an indication of a target distributed ledger to which the information payload should be recorded, and an indication of a second distributed ledger to which a reference that refers to the first distributed ledger should be recorded. The system may provide the information payload to a second system that implements the first distributed ledger. The system may determine that at least a portion of the information payload has been recorded to the first distributed ledger based on providing the information payload to the second system that implements the first distributed ledger. Based on determining that at least the portion of the information payload has been recorded to the second distributed ledger, the system may record the reference, that refers to the first distributed ledger, to the second distributed ledger.
