What is BNB?
BNB was launched in 2017, originally as a token associated with the Binance cryptocurrency exchange, commonly used at the time for purposes such as discounted trading fees. Over time, BNB's role expanded significantly as it became the native asset of BNB Chain, a smart contract platform that supports decentralized applications, separate in function from the centralized exchange itself.
Today, BNB is used both within exchange-related services and as the gas token for paying transaction fees and interacting with smart contracts on BNB Chain.
How does BNB work?
On BNB Chain, BNB functions similarly to how ETH functions on Ethereum: it is used to pay transaction fees ('gas') for transfers and smart contract interactions. BNB Chain uses a Proof of Staked Authority consensus model, in which a limited set of validators, often selected based on staked BNB and reputation, produce and validate blocks.
Separately, BNB has also historically been used within Binance's exchange ecosystem for purposes such as fee discounts and participation in token sale platforms, reflecting its origins as an exchange-linked token.
Common use cases
- Paying transaction ("gas") fees on BNB Chain
- Interacting with smart contracts and decentralized applications on BNB Chain
- Historically used for fee discounts and other benefits within the Binance exchange ecosystem
Key features
- Dual role: exchange-linked utility token and smart contract platform gas token
- Uses a Proof of Staked Authority consensus model with a limited validator set
- Compatible with widely used smart contract tooling, given technical similarities to Ethereum's architecture
Risks and considerations
- Price volatility: BNB's market value can fluctuate significantly.
- Centralization considerations: BNB Chain's validator set has historically been smaller and more curated than some other networks, which some users weigh when evaluating decentralization.
- Exchange dependency: aspects of BNB's utility have historically been tied to a specific centralized exchange's policies, which can change.
- Regulatory considerations: exchange-linked tokens can draw specific regulatory attention in some jurisdictions.
