Although the Ethereum blockchain has a number of founders, Vitalik Buterin was the one who initially published a white paper explaining the concept of Ethereum in November 2013. Following Buterin’s initial work, other brains jumped on board in various capacities to help bring the project to fruition. Vitalik Buterin, Gavin Wood, Charles Hoskinson, Amir Chetrit, Anthony Di Iorio, Jeffrey Wilcke, Joseph Lubin and Mihai Alisie are all considered co-founders of Ethereum.
Ethereum gained awareness in early 2014 when Buterin brought the concept of the blockchain project into the public eye at a Bitcoin conference in Miami, Florida. The project raised capital via an initial coin offering (ICO) later the same year, selling millions of dollars worth of ETH in exchange for funds to use for the development of the project. Between July 22 and Sept. 2, 2014, the asset sale sold over $18 million worth of ETH, paid for in Bitcoin.
Although ETH coins were purchasable in 2014, the Ethereum blockchain did not actually go live until July 30, 2015, meaning ETH buyers had to wait for the blockchain to launch before they could move or use their ETH.
Why create the Ethereum blockchain in the first place? One reason would be that the Ethereum blockchain allows for more versatility in terms of building on the blockchain and the surrounding ecosystem.
