With increasing mentions of CBDCs, maybe it is time to start looking at the actual technology and methods that CBs are looking at to implement them?
Is there already such a thread here on bitcointalk?
Are they looking to use some blockchain construct?
How will their networks be assembled?
What will the 'governance' and 'consensus' mechanisms work?

Aside from a lot of mentions of CBDCs in the finance media, none ever mention the actual implementation details
I would say that the 'Altcoin Discussion' section would be an appropriate place for that - please drop info/ opinions
As to whether they will adopt PoW or POS consus, i may not know what they will implement in this regards but one thing is sure it is going to be highly regulated.
It will work like the fixed exchange rate, which will make them to eliminate volatality of such digital currency.
What i also think is this ; can a digital currency exist without blockchain technology?
