Binance Coin is the cryptocurrency issued by Binance exchange and trades with the BNB symbol. Binance coin initially ran on the Ethereum blockchain with ERC 20 standard but has since become the native coin of the Binance chain. Binance coin has a strict maximum of 200 million BNB tokens.
BNB was initially based on the Ethereum network but is now the native currency of Binance's own blockchain, the Binance chain. Binance was created as a utility token for discounted trading fees in 2017. But since then, its uses have expanded to numerous applications on a wide number of platforms.
