Bank for International Settlement (BIS) Releases Final Report on Project Tourbillion
The Bank for International Settlement (BIS) has published its final report on Project Tourbillion, which focuses on privacy-oriented Central Bank Digital Currency (CBDC) development. The report outlines two prototypes, eCash 1.0 and eCash 2.0, that aim to achieve privacy standards in CBDC usage while maintaining anonymity for users.
Payer Anonymity and Security Features
Payer anonymity is a crucial aspect of the project, protecting the payer’s data while revealing limited information about the payee to ensure transparency. The central bank only receives the identity of the merchant, not personal payment data. The models also prioritize security features to prevent cyber threats and ensure confidentiality.

Scalability and Cross-Border Payment Systems
Scalability is emphasized in creating cross-border payment systems that can handle large transaction volumes during peak seasons. The eCash 1.0 prototype focuses on unconditional payment anonymity and preventing double-spending and counterfeit transactions. The eCash 2.0 model enhances security features while maintaining privacy but requires users to fulfill Know Your Customer (KYC) requirements at a commercial bank.
Privacy Concerns in Europe
Privacy concerns surrounding CBDCs continue in Europe, with data agencies expressing worries about potential violations. However, authorities assure users that the proposed models address associated risks.
Hot Take: CBDCs Can Meet Privacy Requirements, BIS Research Reveals
The Bank for International Settlement’s final report on Project Tourbillion highlights the potential for Central Bank Digital Currencies (CBDCs) to meet privacy requirements while ensuring user anonymity. The project introduces a new privacy paradigm that balances user needs and public policy objectives, protecting payer data while revealing limited information about the payee. Security and scalability are also prioritized in the development of CBDCs. Despite privacy concerns in Europe, authorities assure users that the proposed models address associated risks. As CBDCs continue to evolve, achieving privacy standards will be crucial to gaining public trust and widespread adoption.
