$BNB Binance Smart Chain (BSC) is a blockchain network developed by the cryptocurrency exchange Binance. It operates in parallel with Binance Chain but offers smart contract functionality, making it compatible with the Ethereum Virtual Machine (EVM). BSC aims to provide a fast and low-cost alternative to Ethereum for decentralized applications (DApps) and decentralized finance (DeFi) projects. Developers can create and deploy smart contracts on BSC, and it has gained popularity for its higher throughput and lower transaction fees compared to Ethereum.
