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
Most probably these coins will not be decentralized though they will be blockchain based but centralized and controlled by the governments and state banks and these will most probably be used as an internal currency only initially later they can allow them for international trade payments and remittance etc too.
