Cryptocurrency

A cryptocurrency, often known as a crypto-currency or crypto[a], is a type of digital currency that operates as a means of exchange over a computer network and is not supported or maintained by any one central organization, such a bank or government. 

It is a decentralized method of confirming that the parties to a transaction truly have the monies they claim to have, doing away with the necessity for conventional middlemen like banks when money is being moved between two businesses.
