Cryptocurrency

Cryptocurrency is a type of digital or virtual currency that uses cryptography for security. It operates on decentralized technology, typically a blockchain, which is a distributed ledger enforced by a network of computers (nodes). Unlike traditional currencies issued by governments (fiat), cryptocurrencies are not controlled by central authorities, making them resistant to censorship and fraud. Transactions made with cryptocurrencies are recorded on the blockchain, providing transparency and security. Popular examples include Bitcoin, Ethereum, and Litecoin. Cryptocurrencies can be used for various purposes, such as online purchases, investment, and as a means of transferring value across borders without traditional banking systems.
