Fiat
Fiat money is a type of currency that is not backed by a commodity, such as gold or silver. It is typically designated by the issuing government to be legal tender, and is authorized by government regulation. Since the end of the Bretton Woods system in 1971, the major currencies in the world are fiat money. Fiat money is legal tender that is not guaranteed to be redeemable for gold or silver coins.
