I was a bit concerned about central banks using blockchain technology for their digital currencies, considering the amount of power it uses, but it isn't necessary for Central Bank Digital Currency (CBDC). Phew!
Some central banks also see Bitcoin as the central banks’ competitor andbecause of the digital currency’s association with Bitcoin, many central banks have assumed that Central Bank Digital Currency (CBDC) must be based on a similar set of technologies. This assumption is wrong, and the opposite is actually true.

Consensus. Bitcoin transactions require an elaborate and computationally expensive consensus to verify the validity of the transactions. When using banknotes, the transacting parties do not require a consensus above the consensus not to rob one another. When one pays cash for goods or services, the only consensus necessary is that the two transacting parties deliver the value and the payment. It is straightforward and does not have to be complicated by complex algorithms. A significant portion of the Bitcoin approach and the underlying technical implementation is, therefore, fundamentally useless in the context of CBDC.
China thinks out of the box.
“...most institutions, including regulators, study digital currencies based on blockchain technology, and the People’s Bank of China has broken through that thinking. If it is based on blockchain technology, then the use of digital currency can only be limited to blockchain, [and the use case] scenarios are greatly limited. The digital currency designed by the People’s Bank of China can be used on-line or off-line, even without a network, let alone blockchain. Therefore, we can imagine the space that uses the [PBOC digital currency] is very large.” (footnote 4)

CBDC is marketing spin for 'a bank account at the central bank'.
The Bank of England used to offer a bank account to all its staff and had for 300 years up until 2016.
Now they are looking at rebranding it and bringing it back as a 'digital currency'.
There is no way they will allow anonymity in the system. The last 30 years has been about stripping away anonymity in financial transactions. Hence why you can no longer just endorse a cheque and pass it on.
