EOSIO blockchain is a decentralized system that is powered by its native cryptocurrency, EOS, and supports decentralized applications (DApps) on its platform. Its native EOS tokens are often used for business purposes and can be used as a "stake" for funding DApps in the EOS ecosystem. Introduced in May 2017 by block.one, EOS does not stand for anything specific, because its creators have never formally defined it. Dan Larimer, who foundedBitshares and Steem, is the CTO of block.one.
