What is BNB?

Question

What is BNB?

Accepted Answer

## TLDR
**BNB is the native cryptocurrency of BNB Chain, used to pay for network activity and support its blockchain ecosystem.**

1. It pays transaction fees and supports staking and on-chain governance.
2. It works across BNB Smart Chain, opBNB and BNB Greenfield.
3. It began as a Binance exchange utility token and later expanded beyond that role.

## Deep Dive
### 1. Purpose and uses
BNB is used to pay transaction fees—often called *gas*—when users interact with applications on BNB Chain. It can also be staked to support network operations and used to participate in governance. Binance may offer separate platform utilities, such as trading fee discounts. BNB is not ownership in Binance. ([BNB Chain](https://www.bnbchain.org/en/what-is-bnb))

### 2. Technology and ecosystem
BNB Chain includes BNB Smart Chain, which supports smart contracts and decentralized applications; opBNB, a Layer 2 network designed to scale activity; and BNB Greenfield, a decentralized data storage network. Together, they support uses such as decentralized finance, payments and data services. ([BNB Chain overview](https://www.bnbchain.org/en/blog/exploring-bnb-token-the-heart-of-bnb-chain))

### 3. How it evolved
BNB launched in 2017 as a token associated with Binance, initially providing exchange-related utility. It later became the central asset of the broader BNB Chain ecosystem. Its supply is also reduced through token burns, which permanently remove tokens from circulation; burns do not guarantee any particular market outcome.

## Conclusion
BNB is a utility and network asset that connects activity across BNB Chain with some separate uses on Binance. How will BNB Chain’s applications shape the token’s role over time?
