Binance Chain was launched by Binance in April 2019. Its primary focus is to facilitate fast, decentralized (or non-custodial) trading. Perhaps unsurprisingly, the biggest decentralized application (or DApp) on it is Binance DEX, one of the friendliest decentralized exchanges out there. You can use it via a web interface at binance.org or through its native integration with Trust Wallet.
Due to limitations inherent to blockchain systems, however, the chain doesn’t have much flexibility – smart contracts in a system optimized for fast trading could significantly congest the network. Remember CryptoKitties? At the height of its popularity, it brought the Ethereum blockchain to a standstill.
Scalability remains one of the most challenging hurdles to blockchain development. And that’s where Binance Smart Chain comes in.
