BNB began in 2017 as a fee-discount token for the Binance exchange and now powers BNB Chain. About $75 billion in market value as of July 2026.
What it is
BNB is the token of Binance, the world’s largest crypto exchange by traded volume, and the fuel of BNB Chain, the smart-contract network that grew out of it. It was sold in an initial coin offering in July 2017, days before the exchange itself opened, raising about $15 million for founder Changpeng Zhao and his team. The original pitch was simple: pay your trading fees in BNB and get a discount. One memorable fact: BNB began life as a token on Ethereum, the very platform its own chain would later be built to compete with.
How it works
BNB Chain runs on a system its documentation calls Proof of Staked Authority, in which a small set of validators, elected by BNB staking, take turns producing blocks. The design trades away Ethereum’s large validator count in exchange for speed and low fees. BNB pays gas on the chain, secures it through staking, and still buys the original fee discounts on the exchange. The supply is engineered downwards. Binance committed to removing half of the original 200 million BNB from existence: a quarterly Auto-Burn, set by a published formula, destroys tokens in bulk, and the BEP-95 mechanism burns a portion of gas fees in real time, until only 100 million remain.
The story so far
The token migrated from Ethereum to the standalone Binance Chain in 2019; a parallel smart-contract chain followed in 2020 and boomed during the low-fee DeFi wave; the two merged under the BNB Chain name in 2022. The heaviest moment came in November 2023, when Binance pleaded guilty to US anti-money-laundering and sanctions failures and agreed to pay $4.3 billion, one of the largest corporate penalties in US history. Zhao stepped down as chief executive, later serving a four-month sentence, and the exchange continued under Richard Teng. Through all of it, the burn programme kept to its schedule and the chain kept producing blocks.
Where it stands
As of late July 2026 BNB ranks fourth by market value at about $75 billion (CoinGecko), trading near $562 against a peak above $1,300 in October 2025. Burns have cut the supply to roughly 133 million tokens, two thirds of the way from 200 million to the 100 million target. What to watch: the pace of the quarterly burns, activity on BNB Chain relative to rival low-fee networks, and how far Binance’s regulatory rehabilitation restores its access to institutional customers. BNB remains unusually tied to one company’s fortunes, which has been both its engine and its principal risk since the first day of trading in 2017.
