John Kiff on 08 Mar 24The BIS Innovation Hub and the Hong Kong Monetary Authority have launched the second phase of Project Aurum. Phase 1.0 tested the feasibility of a technological stack that integrates a wholesale interbank system and a retail e-wallet. Phase 2.0 will now focus on how to enhance privacy for retail central bank digital currencies (CBDC). It will explore several privacy-enhancing technologies, including pseudonymization and zero knowledge proofs, and test how increasing privacy affects the performance and compliance of a system.
