Cryptocurrencies use decentralised technology to let users make secure payments and store money without the need to use their name or go through a bank. They run on a distributed public ledger called blockchain, which is a record of all transactions updated and held by currency holders.
Units of cryptocurrency are created through a process called mining, which involves using computer power to solve complicated maths problems that generate coins. Users can also buy the currencies from brokers, then store and spend them using cryptographic wallets.
Cryptocurrencies and applications of blockchain technology are still nascent in financial terms and more uses should be expected. Transactions including bonds, stocks and other financial assets could eventually be traded using the technology.
