Recently, European central bank executives — Thomas Moser from Swiss National Bank and Martin Diehl from Deutsche Bundesbank — stated that central bank digital currencies don’t need a blockchain.
They expressed their opinions by saying that blockchains — especially public, or permissionless — make no sense for central bank digital currencies. The reason is that central banks are central parties; therefore, a blockchain, being a decentralized ledger, is not applicable. It is a pity, but the clerks seem to be unknowingly (or intentionally, who knows?) wrong in their conclusions to why and how blockchain technology can be used, especially with CBDCs.
