We are very proud to have partnered with IBM and contributed to Project Tourbillon, a unique privacy-preserving Retail CBDC prototype by Bank for International Settlements – BIS Innovation Hub and Swiss National Bank.
The project enables new privacy paradigm of payer anonymity to protect purchasers' identities.
The prototype's scalability was tested using payment data.
Quantum-safe cryptography was successfully implemented for future security.
The project developed two different prototypes based on the eCash design, which builds on the existing two-tier banking system. One design, eCash 1.0 (EC1), resembles a cash-like digital payment instrument. The second design, eCash 2.0 (EC2), investigates enhanced security features allowing for strong protection against and detection of counterfeiting.
