Logical architecture for a digital shekel system
The Bank of Israel (BoI) published a paper that examines architecture alternatives for implementing the two-tiered central bank digital currency (CBDC) business model. The paper focuses on the types of participants in the system, the functional distribution between the participants in providing an end-to-end solution, the distribution model to end users; and back-end layer—or system “engine”—managed by the central bank. It concludes that the optimal model is an indirect distribution model, in which the central bank distributes CBDC to the institutions that manage end user's accounts, and those will support distribution to the end users.
