Ethereum

Ethereum is referred to as the second most popular cryptocurrency, after Bitcoin. But unlike Bitcoin—and most other virtual currencies—Ethereum is intended to be much more than simply a medium of exchange or a store of value. Instead, Ethereum is a decentralized computing network built on blockchain technology.
 
Ethereum is a technology that lets you send cryptocurrency to anyone for a small fee. It also powers dApps (decentralized applications) that everyone can use and no one can take down. It's the world's programmable blockchain.
