How does cryptocurrency work? A cryptocurrency is a medium of exchange that is digital, encrypted, and decentralized. Unlike the US dollar or the euro, there is no central authority that manages and maintains the value of a cryptocurrency. Instead, these tasks are widely distributed among users of a cryptocurrency via the Internet. Bitcoin is the first cryptocurrency, Satoshi Nakamoto outlined in a 2004 paper entitled "Bitcoin: Peer-to-Peer Electronic Cash System". Nakamoto described the project as "an electronic payment system based on cryptographic evidence rather than trust". That cryptographic evidence comes in the form of transactions that are verified and recorded in the form of a program called a blockchain.
