Vitalik Buterin (https://vitalik.ca) conceptualized Ethereum in November, 2013. The critical idea proposed was the development of a Turing-complete language that allows the development of arbitrary programs (smart contracts) for blockchain and decentralized applications. This concept is in contrast to Bitcoin, where the scripting language is limited in nature and allows necessary operations only.
