BNB BNB

BNB is the native cryptocurrency of the Binance ecosystem and the BNB Chain. It launched in 2017 as an exchange token offering trading-fee discounts on Binance and has since grown into the gas and staking asset for a Layer 1 blockchain that hosts smart contracts and decentralized applications.

How BNB works

BNB originally launched as a token on Ethereum, then migrated to its own chain. Today it powers the BNB Chain, which combines the BNB Smart Chain (an EVM-compatible smart contract network) with the BNB Beacon Chain for governance and staking. The network uses a proof-of-stake-style consensus with a limited set of validators, which favors speed and low fees over the broad decentralization of larger networks.

Because BNB Smart Chain is EVM-compatible, developers can deploy Ethereum-style smart contracts with familiar tooling. Users pay transaction fees in BNB, and validators stake BNB to help secure the chain and earn rewards.

What BNB is used for

• Trading fee discounts: paying Binance fees in BNB has historically reduced costs.
• Gas on BNB Chain: transactions and smart contract calls are paid in BNB.
• Staking: holders stake BNB to support consensus and earn rewards.
• DeFi and dApps: BNB is the base asset across the BNB Chain ecosystem.
• Token launches: BNB is used to participate in launchpad and other platform offerings.

Tokenomics & supply

BNB began with a supply of 200 million tokens. A defining feature of its tokenomics is the burn mechanism: the team periodically destroys BNB to reduce the total supply over time, with a stated goal of bringing it down toward 100 million. Burns are driven by formulas tied to network activity and other criteria, making BNB's supply deflationary by design.

This shrinking supply is meant to support the token's value as the ecosystem grows. Because issuance is not used to reward block production in the same way as some networks, the supply story for BNB is primarily about reduction through burns rather than inflation.

Risks and considerations

BNB's value is closely tied to the fortunes and reputation of Binance, the world's largest crypto exchange, which has faced regulatory action in several jurisdictions. Concentration risk is significant: legal, operational, or trust issues affecting the company can weigh directly on the token.

The BNB Chain's smaller validator set means it is more centralized than networks like Ethereum, a trade-off for its speed and low fees. As with any crypto asset, BNB is volatile, smart contracts on the chain carry exploit risk, and users should understand custody and regulatory factors before participating.
