About System Contracts

The EOS blockchain is unique in that the features and characteristics of the blockchain built on it are flexible, that is, they can be changed, or modified completely to suit the EOS community needs. Core blockchain features such as consensus, fee schedules, account creation and modification, token economics, block producer registration, voting, multi-sig, are implemented inside smart contracts which are deployed on the EOS blockchain.
