where made ethereum

Ethereum was created by a team of developers led by Vitalik Buterin. The concept was first proposed in late 2013 by Buterin, a programmer and writer involved in the Bitcoin community. Development of the Ethereum platform began in early 2014, and it was crowdfunded through an initial coin offering (ICO) later that year. The Ethereum network went live on July 30, 2015. While Buterin is the most well-known figure associated with Ethereum, other co-founders include Gavin Wood, Joseph Lubin, and Mihai Alisie. The development work was initially managed by a Swiss company called Ethereum Switzerland GmbH (EthSuisse), and later by the Ethereum Foundation, a non-profit organization based in Switzerland.
