Binance Coin (BNB) is one of the most discussed digital assets in the cryptocurrency ecosystem. As the native token of the Binance exchange and the broader BNB Chain network, it plays multiple roles—from reducing trading fees to powering decentralized applications.
Understanding its total supply and operational mechanics is essential for both investors and users navigating the crypto landscape.
Total Supply of BNB
BNB has a fixed maximum supply, meaning the total number of coins that will ever exist is predetermined and cannot be altered. This makes BNB a deflationary cryptocurrency, contrasting with fiat currencies that can be printed indefinitely. Additionally, BNB is a pre-mined cryptocurrency, which means no new tokens can be mined or minted through proof-of-work or similar mechanisms.
The initial total supply of BNB was 200 million tokens. These were distributed as follows:
- 100 million BNB (50%) were sold during the initial coin offering (ICO) in 2017 at a price of $0.15 per token.
- 80 million BNB (40%) were allocated to the founding team.
- 20 million BNB (10%) were distributed among angel investors.
This fixed supply is subject to a token-burning mechanism, which periodically reduces the circulating supply, adding a deflationary aspect to BNB’s economic model.
How Does BNB Work?
BNB operates within the BNB Chain ecosystem, which consists of two main components:
BNB Beacon Chain
Previously known as the Binance Chain, the BNB Beacon Chain handles governance activities such as staking and voting.
BNB Smart Chain
Originally called the Binance Smart Chain (BSC), this component is an Ethereum-compatible smart contract platform and serves as the consensus layer of the BNB Chain.
BNB Chain uses a consensus mechanism known as Proof of Staked Authority (PoSA). Participants can stake BNB to become validators—users who verify transactions and create new blocks. The probability of being chosen as a validator is proportional to the amount of BNB staked.
The number of active validators on BNB Smart Chain was increased from 21 to 41. Among these, 21 are active block producers, while the remaining 20 serve as backup validators.
To become a validator candidate, a user must stake at least 10,000 BNB. Other BNB holders can act as "delegators" by staking their BNB in support of a validator candidate—similar to backing a candidate in a decentralized election.
Validators and their delegators earn transaction fees from the network, paid in BNB. This incentivizes participation and helps secure the blockchain.
Beyond validation, BNB is used for:
- Paying transaction and gas fees on BNB Smart Chain.
- Participating in token sales on Binance Launchpad.
- Earning rewards through staking and liquidity provision.
- Settling payments on various merchant platforms.

Frequently Asked Questions
What is the current circulating supply of BNB?
The circulating supply is less than the initial 200 million due to periodic token burns. Binance conducts quarterly burns until 50% of the total supply is destroyed.
Can BNB be mined?
No, BNB is a pre-mined token. It cannot be mined through computational processes like Bitcoin.
What is the purpose of staking BNB?
Staking BNB allows users to participate in network validation, earn rewards, and contribute to blockchain security and governance.
Is BNB only used on Binance?
No, while initially launched as a utility token for the Binance exchange, BNB now powers the entire BNB Chain ecosystem, including dApps, DeFi protocols, and NFTs.
How often does Binance burn BNB?
Binance conducts token burns quarterly based on trading volume and profitability. The process continues until 100 million BNB remain.
What is the difference between BEP-2 and BEP-20?
BEP-2 is the token standard on BNB Beacon Chain, while BEP-20 is used on BNB Smart Chain. Both are part of the BNB ecosystem but operate on different layers.
Conclusion
BNB has evolved significantly from being a simple utility token for fee discounts on Binance. It now serves as the cornerstone of the BNB Chain ecosystem—supporting DeFi, NFTs, gaming, and more. With its fixed supply and periodic burns, BNB incorporates deflationary traits that may positively influence its long-term value.
As the cryptocurrency market continues to mature, BNB remains one of the most prominent assets with expanding use cases and growing adoption. Whether you're a trader, developer, or investor, understanding BNB’s fundamentals is key to navigating its opportunities.
