Ethereum was proposed in late 2013 by Vitalik Buterin, a cryptocurrency researcher and programmer. Development was funded by an online crowdsale that took place between July and August 2014. The system went live on 30 July 2015.
Ethereum is an open blockchain platform that lets anyone build and use decentralized applications that run on blockchain technology. Like Bitcoin, no one controls or owns Ethereum – it is an open-source project built by many people around the world. But unlike the Bitcoin protocol, Ethereum was designed to be adaptable and flexible.
The primary goal of Ethereum’s founders isn’t to create a cryptocurrency that makes speculators a ton of money; it’s to change the world. The Ethereum community attracts ideological supporters in the same way Bitcoin and other cryptocurrencies do, but it’s use cases give it life far beyond that of other coins.
