Published by Block.one in June 2018, the EOSIO software is a blockchain-based smart contract platform aiming to power large-scale decentralized applications. The network uses a computation and storage resource exchange in place of transaction fees to create an easier user experience. Chief technology officer Dan Larimer previously founded two blockchain networks, Steem and BitShares.
The EOS protocol operates on a different consensus algorithm than Bitcoin’s proof-of-work called delegated proof-of-stake, which prioritizes speed and scalability over absolute censorship-resistance and decentralization.
A unique aspect of EOS is its approach to governance, or how tokenholders on the network vote and implement changes to the protocol over time. When a new user joins EOS, they must first sign the EOS User Agreement, which defines the rights of users on the network as well as methods for dispute resolution.
EOS is competing against a growing number of smart contract platforms including Ethereum, Cardano, NEO and Tezos, among others.
