The Bank for International Settlements Innovation Hub BIS Innovation Hub (BISIH) published a paper focusing on the international dimension of central bank digital currency (CBDC) design. BISIH compared similarities and differences of four cross-border CBDC projects: Inthanon-LionRock2, Jura, Dunbar and mBridge.

All experiments enabled multiple currencies and assets to settle in a single system. The impact was lowered transaction costs, faster settlement and increased operational transparency. While operationally feasible, there remain further considerations on policies relating to transparency and access, legal and governance frameworks, and finally systemic / economic implications.

In addition, the paper outlines technology considerations and implementations, specifically on nodes, networks and data

BISIH affirms that continued experimentation will help further understand systems, platforms and their interactions.
