The European Central Bank (ECB) published a report on the possible issuance of a digital euro

The European Central Bank (ECB) today published a comprehensive report on the possible issuance of a digital euro, prepared by the Eurosystem High-Level Task Force on central bank digital currency (CBDC) and approved by the Governing Council.
Digital euro would complement cash, not replace it. The Eurosystem will continue to issue cash in any case.
A public consultation will be launched on 12 October. Experimentation will start in parallel, without prejudice to the final decision.
