EDPB published the expert opinion ‘The Digital Euro and its token-based offline modality‘, read the announcement and the opinion (pdf).

From the announcement:

Taking into consideration the joint opinion by the EDPB and the EDPS, the EDPB requested an expert to make an in-depth assessment of the practical feasibility of the “token-based offline modality”, which the EDPB supports. The EDPB also asked the expert to investigate how this solution, suggested by the European Commission and the Eurosystem, can be implemented to ensure the very high level of protection envisaged.

As a result, this report explores the technical feasibility, inherent limitations, possible approaches, and security considerations related to the development of a cash-like, anonymous, and double-spending resistant offline modality for the digital euro.
