Ethereum being an open-source blockchain platform lets you build and deploy decentralized applications which run on the blockchain technology. Like Bitcoin, there is no one to own or control Ethereum – it is an open-source project built with the help of many people around the globe. Unlike the Bitcoin protocol, Ethereum was designed to be flexible and adaptable. It is quite easy to create new applications on Ethereum platform, and with the Homestead release, it is now safe for anyone to use those applications.
Bitcoin a Peer-to-Peer Electronic Cash System was first published in 2008. The use of blockchain for more general uses was already discussed in the original paper; it was not until half a decade later, blockchain technology emerged as a common term. In late 2013, inventor of Ethereum Vitalik Buterin proposed that a single blockchain with the capability to be reprogrammed to perform any arbitrarily complex computation could subsume these many other projects. In 2014, Ethereum founders Vitalik Buterin, Gavin Wood and Jeffrey Wilcke began work on a next-generation blockchain that had the ambitions to implement a general, fully trustless smart contract platform.
