Systems and methods for interoperable blockchains and cross-chain data message communication

A method for interoperability between a plurality of blockchains using cross-chain data message communication, the method comprising:

• receiving, by a computer processor operating as a computing node configured to maintain a copy of a distributed ledger data structure updated in accordance with a consensus protocol for a first distributed ledger data structure, a signed transaction request corresponding to a request to transfer a digital object represented on the first distributed ledger data structure to a second distributed ledger data structure;
• verifying the signed transaction request signed by a private key using a corresponding public key;
• modifying a data field parameter on the digital object being transferred to change the digital object state representation to locked and generate a locked object identifier and a signed locking attestation;
• initiating a cross-chain transaction by calling a relayer subroutine to forward a data object of transaction information to a target computing node associated with the second distributed ledger data structure, the data object of transaction information including the signed locking attestation, the target computing node generating a corresponding wrapped digital object on the second distributed ledger data structure as a wrapped representation of the digital object being transferred, the corresponding wrapped digital object including as a data record payload the signed locking attestation and the locked object identifier;
• receiving, from the relayer subroutine, a second signed transaction request corresponding to the wrapped digital object representing a request to transfer back the digital object originally represented on the first distributed ledger data structure from the second distributed ledger data structure;
• verifying the second signed transaction request signed by a second private key using a corresponding second public key;
• identifying a corresponding locked digital object using the data record payload of the wrapped digital object;
• modifying the data field parameter on the digital object being returned to change the digital object state representation of the corresponding locked digital object to unlocked;
• and
• conducting a burn process to change the state of the wrapped digital object to a burned state where the wrapped digital object cannot be further transferred between public addresses corresponding to digital wallets.

A non-transitory, computer readable medium storing machine executable instructions, which when executed by a processor, cause the processor to perform a method for interoperating a plurality of blockchains using cross-chain data message communication, the method comprising:

• receiving, by a computer processor operating as a computing node configured to maintain a copy of a distributed ledger data structure updated in accordance with a consensus protocol for a first distributed ledger data structure, a signed transaction request corresponding to a request to transfer a digital object represented on the first distributed ledger data structure to a second distributed ledger data structure;
