Cryptologic blockchain interoperation

A method, comprising:

• sending, to a data receiver, a participant public key for a participant node of a distributed ledger technology (DLT) network, the DLT network comprising a plurality of participant nodes, wherein the participant nodes respectively validate a distributed ledger based on a consensus protocol, the data receiver not included in the DLT network;
• receiving, from the data receiver, a request to share token data stored in a blockchain of the distributed ledger;
• generating a certification that the token data is stored on the blockchain, the certification comprising a plurality of digital signatures or a multi-signature of multiple of the participant nodes of the DLT network based on a participant private key paired to the participant public key;
• and
• transmitting the certification to the data receiver, the data receiver configured to verify the certification based on the participant public key.

A non-transitory computer readable storage medium, comprising:

• a plurality of instructions, the instructions executed by a processor to:
• send, to a data receiver, a participant public key for a participant node of a distributed ledger technology (DLT) network, the DLT network comprising a plurality of participant nodes, wherein the participant nodes respectively validate a distributed ledger based on a consensus protocol, the data receiver not included in the DLT network;
• receive, from the data receiver, a request to share token data stored in a blockchain of the distributed ledger;
• generate a certification that the token data is stored on the blockchain, the certification comprising a plurality of digital signatures or a multi-signature of multiple of the participant nodes of the DLT network based on a participant private key paired to the participant public key;
• and
