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.
