Binance Coin (BNB) is a digital currency widely used for trading on the Binance cryptocurrency exchange.
Binance Coin started as an Ethereum-based (ERC-20) token to trade cryptocurrencies but eventually moved to its custom blockchain called Binance Chain. Binance Coin transacts purely in cryptocurrencies and utilizes a byzantine-fault-tolerant (BFT) consensus mechanism to speed up the transaction validation process.
