I've thought a bit about which characteristics CBDC's would have and came up with this:

Possible characteristics of cbdc’s:

- Faster payments

- Unit of account

- Currency not backed by debt or loans

- Easier to distribute stimulus checks or ubi

- Automated negative interest rates directly (discourage saving)

- Automated tax collection

- Automated surveillance (transparency of all transactions to governments)

- Automated censorship of certain transactions that are a result of political decisions

- Automated increasing supply of total currency (determine the supply by issuing the currency proportional to the bailout schemes that they need to prevent failing banks. So if a bank fails, one by one, people can log in to their new cbdc account to reclaim their deposit guarantee money and unwind their debt jubilees.)

- Algorithmic monetary policy that takes away the subject of decision making (so tie in the money policy, based upon inflation/deflation goals. This would also create more transparency in a way.)

- Expiration of money (for instance, ubi that has to be spend within 3 months after receiving it, otherwise one loses that money. All to incentivise people to engage in more economic activity and consumerism.)

Their trick will be that some characteristics will be implemented from the start, so it's convenient and lures people in that system. And only later other characteristics get activated.
