Binance Smart Chain (BSC)
Binance Smart Chain is a decentralized and cost-efficient public chain that Ethereum developers can easily get started with and smart contracts are seamlessly compatible. The network uses a modified version of proof-of-stake (PoS) consensus known as a proof-of-staked-authority (PoSA) algorithm.
