Project Polaris: secure and resilient CBDC systems, offline and online
The BID Innovation Hub Nordic Centre Project Polaris is exploring the provision of offline central bank digital currency (CBDC) payments functionality, which could address requirements for resilience, crisis robustness, financial inclusion, cash resemblance, accessibility and other desiderata. Central banks considering the potential implementation of CBDCs with offline functionality must take into account issues such as security, privacy, risks, the types of solution, their maturity and applicability, and operational factors, among others.
