Noone was able to hack the cohoax QR codes.

That is the point. The fucking obvious point is that you don't even need to hack anything, if you understand how all that stuff really works. I had several EU QR codes and a dozen of Russian ones without any efforts, and they worked perfectly for me everywhere and every time when it was necessary to fool authorities about my vaccination status. That's what happens when dumb people with power try to use things they don't understand at all.

But even if we assume they are hackable that is no solution because CBDC will not be.

Everything is hackable. The question is just does it worth hacking. CBDC, by its centralised nature should have a private key of government or CB certificate to work and sign blocks. As soon as you obtain that key, you will be able to control not just your CBDC coins, but all CBDC money that was issued by CB. I tell you, they don't understand how that work, and consequences of playing with things they don't understand. I think that as soon as issued CBDC total value become large enough, the question of does it worth to try to get private key of government/CB will get its obvious answer.
