What is BNB?
BNB is the native token of the Binance ecosystem, launched in 2017. It serves several functions: it pays reduced fees on the exchange, pays gas on BNB Smart Chain (its own EVM-compatible network) and is burned quarterly to reduce the supply. It is closely tied to the financial health of the exchange operator.
How it works
BNB was originally issued as an ERC-20 token on Ethereum and later migrated to its own blockchain, BNB Smart Chain (BSC), a Layer 1 network compatible with the Ethereum EVM that offers significantly lower fees. Consensus is Proof of Staked Authority with 21 rotating validators. The initial supply of 200 million BNB is reduced progressively through quarterly burns (the Auto-Burn program since 2021) until reaching a target maximum supply of 100 million units.
Use cases
BNB has three main uses. As a utility token on the Binance exchange: discounted trading fees, access to launchpads, VIP tiers, earn products. As gas on BNB Smart Chain: payment of all transactions on a network with significantly lower fees than Ethereum, which has made BSC one of the most active networks for DeFi and mass-market applications. And as a deflationary mechanism via the quarterly Auto-Burn, which removes BNB from the market proportionally to the exchange's volume.
Risks and institutional dependence
The health of the token is closely tied to that of the Binance exchange, which adds a relevant regulatory risk component. The actions of the SEC, the CFTC and the US Department of Justice during 2023 led to governance changes, a landmark settlement that still shapes the company's trajectory and the departure of Changpeng Zhao (CZ) as CEO. The decentralization of BSC is limited (21 validators with a close relationship to Binance), which structurally differentiates it from more decentralized networks such as Ethereum.
Frequently asked questions
What is BNB?
BNB is the native token of the Binance ecosystem, launched in 2017. Originally an ERC-20 token on Ethereum, it migrated to the proprietary BNB Smart Chain blockchain. It serves utility functions on the exchange (fee discounts, launchpad access), as gas on BNB Smart Chain and as a deflationary mechanism via quarterly burns.
What is the total supply of BNB?
The initial supply was 200 million BNB. Through the quarterly burn program (Auto-Burn since 2021) the supply is reduced progressively toward a target maximum of 100 million units. As of May 2026 the circulating supply is approximately 135 million.
What risks does BNB have?
The main risk is dependence on the Binance exchange. Regulatory changes, sanctions or operational problems at the exchange directly impact the token. The decentralization of BNB Smart Chain is limited (21 validators with close ties to Binance), unlike networks with thousands of validators such as Ethereum. For investors who prioritize decentralization, BNB has a profile closer to an equity token than to a neutral cryptocurrency.
What is BNB Smart Chain?
BNB Smart Chain (BSC) is the Layer 1 blockchain owned by Binance, compatible with the Ethereum EVM but with Proof of Staked Authority consensus among 21 validators. It offers significantly lower fees than Ethereum, which has made it one of the most active DeFi networks by number of users. BNB is the native gas token of BSC.
