The Digital Dollar Project (DDP) released a new version of its white paper "Exploring a U.S. CBDC" on Jan. 18. The project expanded the paper in order to examine central bank digital currency projects internationally, though its focus is still on the United States.
The DDP introduced its “champion model” of an intermediated wholesale and retail CBDC in the first version of the paper in May 2020. Since that time, CBDC projects worldwide have increased from 35 to 114. The updated DDP paper retains the core tenets of the champion model, such as those on privacy and monetary policy, while discussing the technological advancements of recent years.
