What is a CBDC?

A central bank digital currency (CBDC) is a digital currency issued by a central bank. It is designed to be used as a legal tender and to complement or replace traditional fiat currencies.

CBDCs are still under development, but they have the potential to revolutionize the global financial system. They can make payments faster, more efficient, and more affordable. They can also help to reduce fraud and financial crime.

How do CBDCs work?

CBDCs are based on blockchain technology, which is the same technology that underpins cryptocurrencies like Bitcoin. Blockchain is a distributed ledger that allows transactions to be stored securely and transparently.

CBDCs are issued by the central bank and are stored in digital wallets. Users can use their digital wallets to make payments to other users or to merchants.

CBDC payments are instantaneous and can be made 24/7. They are also very low-cost, as there is no bank intermediary involved.

The types of CBDCs

There are two main types of CBDCs:

• Retail CBDCs: Retail CBDCs are designed for use by the general public. They can be used to make payments for goods and services, as well as to transfer money between individuals.
• Wholesale CBDCs: Wholesale CBDCs are designed for use by financial institutions. They can be used to settle payments between banks and other financial institutions.

CBDCs offer a number of benefits over traditional fiat currencies and cryptocurrencies:

• Faster and more efficient payments: CBDC payments are instantaneous and can be made 24/7, unlike credit card or bank transfer payments, which can take several days.
