June 16 (Cointime) - A new report has revealed that central banks have conducted a joint experiment to test ways to connect monetary authorities and the private sector to facilitate retail digital currency payments. The experiment, called "Project Rosalind," developed 33 application programming interface (API) functionalities to test more than 30 central bank digital currency (CBDC) use cases, including offline payments. The Bank of England is currently consulting on a digital pound and has said it would host the centralized ledger and the API for a potential digital pound. The experiment tested a diverse range of payment options, including online, offline, and in-store payments via interactions with QR codes, mobile phones, smart cards, and more.
