The European Central Bank has officially outlined three distinct models for enabling the use of central bank money on distributed ledger technology (DLT) networks. This initiative is part of a broader effort to modernize financial market infrastructure and ensure that central bank currency remains the anchor for settlement in a digital-first economy.

The first model involves a 'trigger solution,' where the central bank system remains separate from the DLT platform but interacts with it to trigger settlement in existing central bank accounts. The second model, referred to as the 'interoperability solution,' utilizes a dedicated interface to link the DLT platform with the central bank's real-time gross settlement system. The third model, the 'DLT-based solution,' involves the central bank issuing a tokenized form of central bank money directly on a DLT platform, effectively bringing the currency onto the blockchain itself.

While the ECB has presented these as viable pathways, the report emphasizes that the choice of model depends on the specific requirements of the financial market and the level of integration desired. The proposal is currently under review by stakeholders, and the ECB has not yet committed to a single implementation strategy. The move is widely seen as a response to the growing interest in tokenized assets and the need for a secure, regulated settlement asset that can operate within the constraints of modern blockchain technology.
