Project Tourbillon explores cyber resiliency, scalability and privacy in a prototype CBDC
The Bank for International Settlements (BIS) published an update on Project Tourbillon, which explores privacy, security and scalability for retail central bank digital currency (CBDC). The experiment proposes a concept of payer anonymity, providing cash-like anonymity to the payer, combining proven technologies such as blind signatures and mix networks with the latest research on cryptography and CBDC design suggested by David Chaum and Thomas Moser’s eCash 2.0 platform. Project Tourbillon explored not only current, but also quantum-safe blind signatures, an important cryptography used in both designs to guarantee privacy and future security. Tourbillon also demonstrated that implementing quantum-safe cryptography is possible, but it severely limits performance. [Read more at the BIS]
Bank of Canada publishes report on digital dollar consultations
The Bank of Canada published a report on the feedback it has received to date about a potential digital Canadian dollar. It confirmed that Canadians place a high value on central bank-backed cash and want to maintain access to bank notes. Also, Canadians value their right to privacy and many expressed concerns that a digital dollar could compromise that right. In addition, they don’t want a digital dollar that will add to financial stability risks. The Bank reconfirmed that likelihood of a digital loonie being needed is still uncertain, and the ultimate decision whether to go ahead with one depends on the Parliament.

IMF, World Bank and BIS in first ‘tokenisation’ collaboration
The BIS, IMF, World Bank, and Swiss National Bank have launched a project aimed at applying tokenization to the paper-based processes used when richer countries donate into some of the World Bank’s funds to support poorer parts of the world. The idea is to tokenize the original paper-based “promissory notes” to make it easier to transfer when required. [Read more at the BIS]
Central Bank of Solomon Islands to start CBDC proof of concept
The Central Bank of Solomon Islands (CBSI) started a retail CBDC (“Bokolo Cash”) proof-of-concept (PoC) on November 1, 2023. The CBSI has been testing the Soramitsu-provided system for domestic and foreign payments, including simulated international remittances. Within the PoC, users will be able to seamlessly scan a QR code with their Bokolo Cash wallet to send instant cash payments to selected merchants or make peer-to-peer transfers.

Retail CBDC implications for banking and financial stability
The U.S. Federal Reserve (Fed) published a review of the literature that examines the risks to the banking sector associated with retail CBDC introduction. These include the possibility of bank disintermediation and associated contraction in bank credit, as well as potential adverse effects on financial stability. The recycling of the new CBDC liability through asset purchases or lending by the central bank plays an important role in determining the economic consequences of the introduction of a CBDC. Ultimately, the effects of a CBDC depend critically on its design features, of which remuneration is the one discussed most often in the literature. [Read more at the Fed]
