BNB Smart Chain is an innovative solution to bring programmability and interoperability to Beacon Chain. BNB Smart Chain relies on a system of 50 validators with Proof of Staked Authority (PoSA) consensus that can support short block time and lower fees. The most bonded validator candidates of staking will become validators and produce blocks. The double-sign detection, malicious vote detection and other slashing logic guarantee security, stability, and chain finality. Other than the 29 active validators, BSC will introduce more validators, e.g. another 20 inactive validators, into the validator set as backups, which will be called "Candidates".
