Binance Coin is not designed to be mined in the traditional sense (solving complex mathematical problems or contributing computing power), as it is not based on a proof-of-work consensus mechanism.
Instead, BNB was issued through a process called an initial coin offering (ICO). During BNB’s ICO, a fixed number of BNB was created and sold to participants in exchange for other cryptocurrencies. Once the ICO concluded, all BNB was then distributed to participants and became tradeable on cryptocurrency exchanges.
