After the recent outages in Spain etc, which brought commerce to a standstill, I hear the EU has been crowing that if we had the CBDC this wouldn't be a problem, as it will work without electricity.
I don't really believe that CBDCs work without electricity because it relates not only to CBDCs themselves but also to merchant operations and user payments that all need power supplies as well as internet connection.
A world without electricity and Internet connection are a dead world in modern era and electricty is very important because without it, there is no operation of merchants and many payment infrastructures. With Internet connection, you can have it with cable, non-cable connections or with Satellite Internet but the bottom line is you need Electricity first.
