What is BNB (BNB)?

BNB is the cryptocurrency that powers BNB Chain, a fast and low-cost blockchain network originally created by the giant crypto exchange Binance. In simple terms, BNB is a digital coin you can use to pay fees, run apps, and trade, and it was first designed to give people a discount when buying and selling on Binance. Today it sits among the largest cryptocurrencies in the world, currently ranked #4 by market value.

What is BNB in simple terms?

Imagine a big online marketplace where millions of people trade digital money every day. To use that marketplace smoothly, it helps to have a special token, like an arcade coin you slot into machines to play games. That special token is BNB.

BNB started life in 2017 with a simple job: holders could use it to pay their trading fees on Binance and get a discount. Over the years it grew into something much bigger. Now it is the main fuel for an entire blockchain (a shared digital record book that no single person can secretly change). When people say "BNB crypto", they usually mean both the coin itself and the wider network it runs.

Who created BNB and when?

BNB was launched in July 2017 by Binance, a cryptocurrency exchange founded by Changpeng Zhao (often called "CZ"). An exchange is like a digital currency shop where you can swap one coin for another or buy crypto with regular money.

It was first introduced through an ICO (initial coin offering), which is a way new crypto projects raise money by selling their tokens early, a bit like a company selling shares before it is famous. At the very start, BNB lived on the Ethereum blockchain as a simple token. Later, Binance built its own blockchain and moved BNB over to it, giving the coin its own home network.

How does BNB work?

BNB runs on BNB Chain, which is actually made up of two connected parts that work as a team:

• BNB Smart Chain (BSC) — the busy part where apps live. It supports smart contracts (small programs that run automatically when their rules are met, like a vending machine that gives you a snack the instant you pay).
• BNB Beacon Chain — the part that historically handled the network's core voting and security rules. (The network has been streamlined over time, but the two-layer idea is helpful for understanding its design.)

To keep the network honest, BNB Chain uses a system where trusted computers called validators take turns checking transactions and adding them to the shared record book. They are chosen partly based on how much BNB is staked (locked up as a safety deposit). This approach is much faster and cheaper to run than the older "mining" method that some coins use, which is why fees on BNB Chain are usually tiny fractions of a cent.

Every time you do something on the network, like sending tokens or using an app, you pay a small fee in BNB. Think of it like the toll you pay to drive on a highway: the toll keeps the road running smoothly and pays the people who maintain it.

What is BNB used for?

BNB is one of the more useful coins out there because it has many real jobs. Here are the main ones:

• Paying trading fees — holders can use BNB to pay fees on Binance and receive a discount, the original reason it was created.
• Gas for the network — BNB is the "fuel" (often called gas) needed to run any transaction or app on BNB Chain.
• Using apps — thousands of DeFi (decentralized finance, meaning money services with no bank in the middle) apps, games, and marketplaces on BNB Chain accept BNB.
• Staking — you can lock up BNB to help secure the network and earn rewards in return, a bit like earning interest in a savings account.
• Paying for goods and services — some online and real-world merchants accept BNB as payment.

What makes BNB different?

Many coins are tied to a single idea. BNB is unusual because it is backed by one of the biggest companies in the crypto world, and that gives it a lot of built-in demand and real-world use.

One feature people talk about a lot is the token burn. "Burning" means permanently destroying some coins by sending them to an address no one can open, like shredding cash so it can never be spent again. Binance regularly burns BNB with the stated goal of slowly reducing the total supply over time. The plan is to keep burning until the supply shrinks toward a target of 100 million coins (down from the 200 million created at launch). Fewer coins in existence can, in theory, make each remaining coin more meaningful, though prices always depend on many factors and are never guaranteed.

BNB also stands out for being fast and cheap. Because of how its validator system works, transactions confirm in seconds and usually cost very little, which is why so many beginners and app builders choose BNB Chain.

How do you buy and store BNB?

Buying BNB is straightforward. You can purchase it on Binance and on many other major crypto exchanges. The usual steps are: create an account, verify your identity, deposit regular money or another crypto, and then swap it for BNB.

Once you own BNB, you need somewhere safe to keep it. This is called a wallet, a digital app that holds the secret keys (long passwords) that prove the coins are yours. There are two main kinds:

• Hot wallets — apps connected to the internet, handy for everyday use but more exposed to hackers.
• Cold wallets — small physical devices kept offline, much safer for large amounts, like a vault instead of a pocket.

The golden rule: whoever controls the secret keys controls the coins. Never share your seed phrase (the list of recovery words for your wallet) with anyone, ever.

Is BNB safe? Risks to know

BNB is a well-established coin with a large, active network, but no cryptocurrency is risk-free. Here are the honest things a beginner should understand:

• Price swings — BNB's value can rise and fall sharply in a short time. Only ever use money you can afford to lose.
• Central influence — BNB is closely linked to Binance. That brings strength and resources, but it also means the coin is more tied to one company than truly decentralized coins are.
• Regulation — governments around the world are still writing the rules for crypto, and changes can affect how exchanges and coins operate.
• Scams — because BNB Chain is so popular, scammers create fake tokens and apps on it. Always double-check links and never approve transactions you don't understand.

None of this means BNB is "bad" — it simply means you should learn before you leap. This article is educational, not financial advice, so always do your own research before buying any crypto.

Frequently asked questions about BNB

What does BNB stand for?

BNB originally stood for "Binance Coin," reflecting its link to the Binance exchange. Today it is most often referred to simply as BNB, and the network is called BNB Chain.

Is BNB the same as Binance?

Not exactly. Binance is the company and exchange; BNB is the cryptocurrency that powers Binance's blockchain, BNB Chain. They are closely connected, but one is a business and the other is a digital coin you can own.

How is the supply of BNB controlled?

BNB began with 200 million coins. Through regular token burns (permanently destroying coins), the supply is being gradually reduced over time toward a target of 100 million, which is meant to make the remaining coins scarcer.

Can I use BNB outside of Binance?

Yes. Beyond the Binance exchange, BNB is used as gas to run thousands of apps on BNB Chain, for staking, for trading on other platforms, and as payment with merchants who accept it.
