Ethereum was created in 2014 by Vitalik Buterin. It is the second most capitalized cryptocurrency after Bitcoin, which also operates on the open source model, with a decentralized network. Ethereum is mainly used for the creation of smart contracts and decentralized applications. He is also behind the creation of so-called ERC-20 tokens which allow other projects to launch their ICOs (Initial Coin Offering) 

Vitalik Buterin is therefore the main craftsman of the creation of Ethereum. He became interested in Blockchain technology from the age of 17 and was part of the Bitcoin programmer team in 2011. His main idea: to go beyond Bitcoin and develop a platform that allows something other than the simple exchange of cryptocurrency. The Ethereum Whitepaper was launched in 2013 and caught the attention of members of the crypto community of the time.

Determined to carry out his project, Vitalik Buterin embarked on a crowdfunding campaign and managed to raise $ 18 million. Programmers are won over by the project’s objectives, and the first version of Ethereum is released in 2015, first under the name of "Frontier".
