$BNB BNB (Build'N'Build), formerly Binance Coin, is the native cryptocurrency of the BNB Chain ecosystem. Launched in 2017 by Binance, it was initially used to provide trading fee discounts on the exchange. Over time, BNB evolved into a versatile utility token powering decentralized applications, DeFi platforms, staking, and governance. It uses a Proof of Staked Authority (PoSA) consensus model, enabling fast, low-cost transactions. Binance regularly burns BNB to reduce supply, aiming for a maximum of 100 million coins. With its wide adoption and strategic corporate interest, BNB remains one of the top cryptocurrencies by market capitalization, driving innovation across blockchain ecosystems.
