Why it stands apart
A blockchain ecosystem built around BNB.
BNB Chain uses a limited validator set and is historically connected to Binance, while the chain and the exchange are different services.
Bottom line: BNB Chain has its own design, trade-offs, and risks. Learn the network before you use the asset.
Follow the money
What happens after you hit send.
- A signed transaction pays BNB gas.
- Validators order and execute it under BNB Chain rules.
- The resulting block updates the chain's shared state.
Know the economics
Where new BNB comes from.
BNB began with 200 million tokens. Supply has been reduced through burn mechanisms; consult current protocol documentation for the live amount.
Protect the downside
The mistake you cannot undo.
A token labeled BNB can exist on multiple networks. Wrong-network transfers and fake dApps are common sources of loss.
Go beyond the summary
The subject in plain English.

Who is behind it?
Binance ecosystem. Names can explain a project’s history, but they do not make an asset safe or guarantee its future.
What keeps the record
BNB Chain uses Proof of Staked Authority. A limited validator set helps produce blocks quickly. As with any chain, check the exact network before sending assets.
Supply, fees, and incentives
BNB began with 200 million tokens. Supply has been reduced through burn mechanisms; consult current protocol documentation for the live amount.

What people use it for
Where this matters.
- Learn how the network records activity
- Understand the difference between the asset, the network, and the company around it
- Recognize the correct network before a transfer
- Check whether a wallet or service actually supports this asset
Before you act
Verify before you sign.
- Find the project through an official link, not an ad, reply, or direct message.
- Confirm the exact name, ticker, network, and token or contract address.
- Do not share a recovery phrase, private key, or remote access with anyone.
- Use a small test transaction before moving an amount that matters.
- Treat every purchase, yield offer, or app approval as a separate risk decision.
