Ethereum is a decentralized platform that runs smart contracts: applications that run exactly as programmed without any possibility of fraud or third party interference.
In order to run these applications, people need to use Ether, the native token of Ethereum. Ether is used to pay for gas, a unit of computation used in Ethereum.
