Ethereum is an open-source, blockchain-based operating system designed to create smart contracts.
Ethereum was introduced by cryptocurrency researcher and programmer Vitalik Buterin at the end of 2013. The system was launched on 30 July 2015 with the sale of 11.5 million coins.
As a result of security problems in 2016, Ethereum blockchain was divided into two. The original Ethereum blockchain is called Ethereum Classic. Ethereum is still the 2nd most valuable crypto and Ethereum Classic is the 18th most valuable crypto.
It is an interesting choice to give the name of ether, a volatile gas for a Crypto money, on a monetary issue where trust is essential. Buterin said that he chose this name because the environment in which light is moving is called as "ether" and because it sounds pleasant.
In March 2017, the Enterprise Ethereum Alliance (EEA) was established with the participation of various blockchain startups, research groups and companies. By July 2017, the Union had more than 150 members.
