In this chapter, we talk about three main topics. We first define the issues that a central bank digital currency (CBDC) could address and the reasons to enhance our understanding of CBDCs. Second, we discuss the optimal design principles of a CBDC as they arose from various conversations with central banks, national and supranational authorities, market participants, and academics in various jurisdictions. Finally, we propose a well-rounded and robust solution for a retail CBDC based on Algorand technology which meets these design principles. Most of the content of this chapter is borrowed from the White Paper Issuing Central Bank Digital Currency Using Algorand by Civelli, Georg, Grassano, and Ihsanullah (2022). In that paper, we extensively cover the CBDC design and issuance topics, informed by our recent participation in various pilots, studies, and round-table conversations on these topics.
