Abstract: A system for enabling communication between blockchains on heterogeneous blockchain networks. The system can include a sending blockchain network comprised of a sending blockchain that includes a plurality of blocks, each block including a block header and one or more transaction values associated with an identification request transmitted by the sending blockchain. The system can include a directory service node configured to receive the identification request from the sending blockchain, and identify a receiving blockchain, which forms part of a receiving blockchain network. The system can include an identity service node configured to receive a trust request from the directory service node to determine whether a valid trust certificate is available for the receiving blockchain, and enable communication between the sending blockchain and the receiving blockchain, when the valid trust certificate is determined to be available.

Abstract: A method and system are disclosed to audit smart contracts. The method includes: publishing, with a processing server, a smart contract bytecode with metadata on a blockchain; retrieving, with the processing server, the published smart contract bytecode with metadata from the blockchain; extracting, with the processing server, the smart contract bytecode from the published smart contract bytecode; and verifying the smart contract bytecode by comparing a computed hash of a high-level source code of the published smart contract bytecode with the metadata retrieved from the blockchain.

Abstract: A method for providing consent for provisioning data in an opaque blockchain, includes: receiving, by a receiver of a processing server, a consent request for data associated with the processing server stored on a blockchain, the consent request including at least two digital signatures, where a first digital signature is generated by a regulating entity and a second digital signature is generated by a moderating entity in the blockchain network; validating, by a processing device of the processing server, the first digital signature and the second digital signature; digitally signing, by the processing device of the processing server, the received consent request using a private key of a first cryptographic key pair; and transmitting, by a transmitter of the processing server, the digitally signed consent request to the regulating entity.

Abstract: Delegating issuance capability to a third-party of fungible digital assets involves a central (e.g., central bank) processor receiving a request to issue fungible digital assets from a third-party node; verifying the request; validating request to issue fungible digital assets from the third-party; approving or rejecting the request; if the request to issue fungible digital assets is approved, creating an issuance authorization message; executing a smart contract clause to add an entity of the third-party node to a list of authorized entities; publishing the issuance authorization message on a blockchain indicating that a third-party node has been added to the list of authorized entities; and publishing a revocation message on the blockchain revoking an authorization granted to the third-party node to issue digital assets.

Abstract: A system for communicating between blockchains on heterogeneous blockchain networks. The system can include a sending blockchain configured to transmit a first message via a sending blockchain protocol, wherein the sending blockchain forms a part of a sending blockchain network. The system can include a sending adapter node configured to receive the first message from the sending blockchain, and translate the first message from the sending blockchain protocol to an adapter protocol. The system can include a receiving adapter node configured to receive the first message from the sending adapter node, and translate the first message from the adapter protocol to a receiving blockchain protocol. The system can include a receiving blockchain configured to receive the first message from the receiving adapter node, and validate the first message, wherein the receiving blockchain forms a part of a receiving blockchain network.
