Binance Smart Chain is a cutting-edge solution that adds programmability and interoperability to the Binance Chain platform. Binance Smart Chain is based on a 21-validator system with Proof of Staked Authority (PoSA) consensus, which allows for faster block times and reduced fees. Candidates for staking who are the most bonded will become validators and produce blocks. Security, stability, and chain finality are all ensured by the double-sign detection and other cutting logic. Binance Smart Chain (BSC) is a blockchain network that allows smart contract-based applications to be executed. BSC works in tandem with Binance's native Binance Chain (BC), giving customers the best of both worlds: BC's huge transaction volume and BSC's smart contract functionality.
