A cryptocurrency created by Block One which supports smart contacts much like Ethereum. EOS uses delegated proof of stake to confirm transactions, which leads to confirmed speeds of at least 1000 transactions per secund, as opposed to Ethereum's 15 transactions per secund. The developers of Block One claim EOS, as a cryptocurrency, is not an acronym.
