Ethereum (ETH) is the second most popular cryptocurrency after Bitcoin. Founded by Vitalik Buterin and Gavin Wood in 2015 — Ethereum, the second-biggest cryptocurrency after Bitcoin, is a blockchain-powered platform for creating decentralized applications (dapps). Where Bitcoin was designed as a currency and a store of value, Ethereum is a decentralized network for running smart contracts code that runs on a peer-to-peer network and is verified by Ethereum’s blockchain.
