BNB Chain is a blockchain ecosystem that originated from [[Binance]], the world's largest cryptocurrency exchange. It's designed to be fast, efficient, and developer-friendly, supporting the creation of decentralized applications ([[dApp]]s) and smart contracts. BNB Chain consists of two blockchains: [[BNB Beacon Chain]] (for governance) and [[Binance Smart Chain (BSC)]] (for smart contracts and [[Ethereum Virtual Machine (EVM)]] compatibility). Its native token, BNB, is used for transaction fees, staking, and governance within the ecosystem. BNB Chain aims to provide an alternative to [[Ethereum]] with lower fees and faster transaction speeds.
