CBDC (Central Bank Digital Currency) is a digital currency that is managed by central banks. It exists in virtual form on distributed ledgers like blockchain. Many countries are exploring CBDC as it offers advantages over physical cash and private cryptocurrencies. CBDCs would be directly issued and backed by central banks, making them safer and more stable than alternatives. They could reduce transaction costs and processing times while improving accessibility of financial services. Central banks are still researching the best technical designs for CBDCs, which may either use accounts or digital tokens on a blockchain network.
