Many cryptocurrencies are built on blockchain technology, which is a distributed ledger enforced by a distributed network of computers. Cryptocurrencies are distinguished from fiat currencies like the United States dollar or the British pound because any central authority does not issue them, making them potentially impervious to government intervention or manipulation.
