In 2013, Hoskinson quit a consulting job to begin a project called the Bitcoin Education Project. According to Hoskinson, the limited supply makes Bitcoin like a digital form of gold. Cardano logo, a cryptocurrency developed by Hoskinson's company, IOHK. Hoskinson joined the Ethereum founding team as one of eight original founders with Vitalik Buterin in late 2013. For a brief time Hoskinson held the position of CEO at Ethereum. Buterin removed Hoskinson from Ethereum in 2014 after a dispute over whether the project should be commercial (Hoskinson's view) or a nonprofit (Buterin's view). In late 2014, Hoskinson and former Ethereum colleague Jeremy Wood formed IOHK (Input Output Hong Kong), an engineering and research company that builds cryptocurrencies and blockchains.IOHK's key project is Cardano, a public blockchain and smart contract platform that hosts the ADA cryptocurrency. Hoskinson did not pursue venture capital for Cardano, citing that it runs counter to the blockchain's principles. Hoskinson has also said that venture capital involvement might lead to an outsized control of a project. In 2020, Hoskinson spoke at the World Economic Forum in Davos, where he said that blockchain may eventually cause social change.
