The Enterprise Ethereum Alliance (EEA) has released their latest case study focusing on the interoperability of distributed ledger technologies. Something we, at Adhara, are vocal champions of.

Leveraging Corda and Ethereum DLT technologies, the use case demonstrates a Delivery versus Payment (DvP) cross-chain settlement involving a basket of securities traded between two banks — HQLAᵡ managing the delivery leg, Fnality International managing the payment leg (via FnPS) with the tests carried out on the Ecosystem Testnet hosted by Adhara.

Key highlights of the case study include:

• Successful interoperability between a private permissioned Corda network for securities management and a private permissioned Ethereum network for payments.
• Implementation of atomic settlement as per the definition of the Bank of International Settlements, to ensure that the transfer of one asset occurs if and only if the transfer of the other asset also occurs.
• Utilization of the EEA DLT Interoperability Specification to enable secure cross-chain communication.
• Collaboration between EEA members and industry leaders HQLAx, Fnality International, Adhara, QualitaX, Wanchain.

This case study represents a significant milestone in the journey toward standard-driven DLT interoperability implementations. It showcases how adherence to the EEA DLT Interoperability Specification can overcome challenges in communication between distinct DLT platforms, facilitating a more integrated global financial system. It offers insights into the benefits of DLT in securities transactions, including real-time settlement, improved efficiency, and reduced counterparty risks.
