Interoperability Between CBDC and Fast Payment Systems : A Technical Perspective - 0 views

John Kiff on 21 Jul 24The World Bank published a technical paper on on its practical experiments on fast payments system (FPS) interoperability with central bank digital currency (CBDC) systems. The first experiment investigated the option of settling FPS obligations in a wholesale CBDC system, including the option to reserve funds to guarantee the settlement of FPS net obligations. The second experiment investigated the interoperability between users within the FPS and retail CBDC users, including the transfer of funds among both types of users, using common services such as address resolution services. This experiment illustrated how CBDC systems could interoperate with retail payment systems through an interlinking bridge that was used to route messages and application programming interface (API) calls among different systems. The programmability features of distributed ledger technology (DLT) were used to link the settlement in CBDC to the transfer of funds in the FPS.
