Distributed ledger interoperability services

A method for transaction processing using a ledger interoperability service in a blockchain-based distributed ledger system, comprising:

• receiving, at a ledger interoperability service, a pending transaction request for a transaction from a distributed banking ledger in a blockchain-based distributed ledger system, wherein a consensus algorithm operating on a plurality of distributed computer nodes in the blockchain-based distributed ledger system updates the distributed banking ledger in which multiple copies of the distributed banking ledger exist across the plurality of distributed computer nodes;
• validating, by the ledger interoperability service, the pending transaction request;
• enriching, by the ledger interoperability service, the validated pending transaction request with a customer account master attribute, a static account rule, and/or an account status;
• sending, by the ledger interoperability service, a the enriched and validated pending transaction to a posting generation service, wherein the posting generation service creates a posting comprising the enriched and validated pending transaction request and a posting execution service posts a message containing the posting to the ledger interoperability service;
• encrypting, by the ledger interoperability service, the message and providing the encrypted message to the distributed banking ledger;
• receiving, by the ledger interoperability service, an encrypted response message from the distributed banking ledger, wherein the encrypted response indicates success or failure;
• decrypting, by the ledger interoperability service, the encrypted response message and passing the decrypted response message to the posting execution service, wherein the posting execution service provides the posting, a transaction level status, and/or a posting level status to the posting generation service;
• and
• receiving, by the ledger interoperability service, a final confirmation for the transaction.
