Cryptocurrency is a type of digital or virtual currency that uses cryptography for security. Unlike traditional currencies issued by governments (like the US dollar or euro), cryptocurrencies are decentralized and typically operate on a technology called blockchain, which is a distributed ledger managed by a network of computers (called nodes). | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | |
