Binance Smart Chain (BSC) is a blockchain built by Binance that is independent of, but runs parallel to Binance Chain. BSC's focus is to facilitate fast, decentralized trading, with the aim to lower transaction cost. BSC supports smart contracts, which are Ethereum-compatible. BSC runs on a proof-of-stake (PoS) consensus model, which enables it to process transactions faster and be more energy efficient. More information can be found here on Binance.com.
