Ethereum is an open-source, public, blockchain-based distributed computing platform featuring smart contract (scripting) functionality. It provides a decentralized virtual machine, the Ethereum Virtual Machine (EVM). This virtual machine can execute Turing-complete scripts using an international network of public nodes and a token called ether, often referred to as gas (short for "gasoline"). Gas is used to prevent spam on the network and allocate resources proportionally to the incentive offered by the request.
Ethereum was initially proposed in late 2013 by Vitalik Buterin, a researcher and programmer. Development was funded by an online crowdsale during July–August 2014.
Ethereum was initially described in a white paper by Vitalik Buterin, a programmer involved with Bitcoin, in late 2013 with a goal of building decentralized applications. More specifically, Buterin "had argued to the bitcoin core developers that the platform needed a more robust scripting language for developing applications." Failing to gain agreement, he proposed development of a new platform with a more general scripting language. Buterin believes that many applications could benefit from Bitcoin-like software.
The Ethereum software project was initially developed in early 2014 by a Swiss company, Ethereum Switzerland GmbH (EthSuisse). Subsequently, a Swiss non-profit foundation, the Ethereum Foundation (Stiftung Ethereum) was set up as well. Development was funded by an online public crowdsale during July–August 2014, with the participants buying the Ethereum value token (ether) with another digital currency, bitcoin. While there was early praise for the technical innovations of Ethereum, questions were also raised about its security and scalability.
