As a virtual currency, Bitcoin has no physical presence, and its ownership transfers from person to person on a digital ledger, which lives on the Bitcoin network and follows blockchain protocol. Bitcoin holders can electronically transfer funds to complete transactions similar to using a debit or credit card. One of the unique aspects of Bitcoin is that there is no central authority managing transactions, its value, or supply. This is known as decentralised finance (DeFi), where the community regulates transactions while market forces determine the price. In the case of Bitcoin and many other cryptocurrencies, there is also a fixed supply that miners steadily release as a function of transactional demand. Miners approve transactions on the Bitcoin network, ensuring that coins come from the appropriate accounts. They run Bitcoin nodes to ensure everybody follows Bitcoin’s protocols, and the Bitcoin community votes whenever there are proposed changes. The result is digital money that allows for secure peer-to-peer transactions on the Bitcoin blockchain.
