Cryptocurrency

A cryptocurrency is a digital or virtual form of money that uses cryptography to secure transactions and control the creation of new units. It operates on blockchain or distributed ledger technology, allowing peer-to-peer transfers without a central authority. Transactions are verified by network participants through consensus mechanisms such as proof of work or proof of stake. Cryptocurrencies can be used for payments, value transfer, or as a utility within blockchain applications. Their supply and rules are defined by software protocols.
