BNB, BNB Chain, and BNB Smart Chain
BNB is the coin itself, and it does four things: it pays transaction fees, it can be staked with validators, it carries governance votes, and it earns a trading-fee discount on Binance. What BNB is covers all four in full.
BNB Chain is the family of networks the coin belongs to, and it is not a single network. Documentation describes it as composed of three blockchains: BNB Smart Chain, opBNB and BNB Greenfield (source: BNB Chain Docs).
BNB Smart Chain, often shortened to BSC, is the main network in that family and the one people usually mean. It launched on September 1, 2020, runs smart contracts, and charges its fees in BNB (source: BNB Chain Docs). BNB Smart Chain explained covers how it works and what a transaction costs there.
Binance is the company that created the coin and runs an exchange that trades it. The chain runs independently of it, and using one requires no account with the other.
Binance Chain is an obsolete name that appears in old wallets and backups. It referred to what later became Beacon Chain, which has since been retired.
Gas, and what pays for it
Gas is the fee a network charges to process a transaction, and its size reflects how much work the transaction asks for. On every network in the BNB family, gas is paid in BNB.
This produces the most common beginner problem in the whole ecosystem. A wallet holding a large stablecoin balance and no BNB cannot move any of it, because the fee has to come from BNB specifically, and keeping a small reserve of a few dollars avoids the problem entirely.
WBNB, or wrapped BNB, is BNB packaged as a standard token so contracts can handle it the same way they handle everything else. Decentralized exchanges usually wrap and unwrap it automatically without asking, so most people hold it briefly without noticing. It is worth the same as BNB and converts back one for one, though it has to be unwrapped before it can pay gas.
BEP-20 is the token standard on BNB Smart Chain, equivalent to Ethereum's ERC-20. Any token you hold on the chain other than BNB itself is almost certainly a BEP-20 token, and it follows the same model Ethereum established.
The three live networks
BNB Smart Chain is the general-purpose network where applications run, identified by wallets as chain ID 56.
opBNB is a layer-2 network built on top of BNB Smart Chain, processing transactions in bulk and posting compressed records back to the base chain, which makes it much cheaper. Network documentation lists it as chain ID 204, with 5611 for its test network (source: BNB Chain Docs). What opBNB is covers how the batching works and how coins get there.
BNB Greenfield is a network for storing data, recording who owns and who may read each file while independent storage providers hold the bytes (source: BNB Chain Docs). BNB Greenfield explained covers the two separate charges it makes for storage.
The rule that covers all three is worth stating once: each keeps its own balances, and each wants its fee paid from coins already sitting on it. Seeing opBNB in a wallet's network list only means the setting exists, and moving coins across takes a bridge transaction. How BNB Chain works covers how the three divide the work between them.
Beacon Chain and the terms it left behind
BNB Beacon Chain was the network that handled staking and governance before those functions moved to BNB Smart Chain. It has been retired, shutting down at block height 385,251,927 on December 3, 2024 (source: BNB Chain Docs).
BEP2 was its token standard, and bnb1 addresses were its address format, which look nothing like the 0x addresses used everywhere else in the family. Anything showing a bnb1 address belongs to a network that stopped producing blocks in December 2024, so coins sent there have nowhere to arrive.
Fusion is the name for the process that consolidated the two chains into one, moving staking and governance across before the shutdown. Documentation records most Beacon-side services as switched off with it (source: BNB Chain Docs). The Beacon Chain sunset covers what moved and how surviving tokens are recovered.
Staking and validator terms
Validators are the operators that produce blocks, and BNB Smart Chain elects 45 of them each day, ranked by how much BNB is staked behind them.
Cabinet and Candidate are the two tiers within that set. Documentation states that the active validator set consists of 45 validators, being 21 Cabinet and 24 Candidates (source: BNB Chain Docs). Cabinet validators produce blocks far more often, so they earn more, and both tiers are re-ranked daily.
Stake Hub is the contract that records who has staked what, so delegating to a validator means sending a transaction to Stake Hub from a wallet on BNB Smart Chain, and it records your position against the operator you chose.
Delegating is backing a validator with your coins for a share of what it earns, and it is what most holders do. Running a validator is a separate undertaking requiring continuous operation and a substantial locked-up stake of your own. PoSA consensus covers how the election works, and BNB staking covers the holder's side.
Burn terms
Burning means sending coins to an address nobody holds the keys to, permanently removing them from circulation, and BNB does this through two separate mechanisms.
BEP-95 is the per-block burn, destroying a share of the gas collected in each block. That share is a governable value set at 10% when the rule launched (source: BEP-95). It runs continuously and automatically as part of paying validators.
Auto-Burn is the quarterly program, removing a larger amount calculated from a published formula and working toward a total supply of 100 million coins. It is announced in advance and its results are published each quarter.
Anything else described as a BNB burn is almost certainly historical, since these two are the current mechanisms. BNB burns covers the mechanics of both and where the coins go.
Trading terms you will meet
Spot means buying the coin outright, so a spot purchase leaves you holding BNB that can be withdrawn to a wallet and used on the chain, and BloFin has listed BNB/USDT on spot since December 31, 2023, with a minimum order size of 0.001 BNB.
Perpetual means a contract that tracks the price without ever holding the coin. BloFin lists BNBUSDT and BNBUSDC, both at up to 75x leverage. A perpetual settles in cash, which leaves it useful for price exposure and useless for paying a transaction fee.
On BloFin the two are written differently so you can tell them apart at a glance: spot pairs carry a slash, as in BNB/USDT, and perpetual contracts do not, as in BNBUSDT. Other venues use other conventions, so the reliable check is the market you are on rather than the punctuation, since only a spot purchase leaves you holding coins you can withdraw. BNB perpetual futures covers the contracts, and the applications you will meet on the chain use the same vocabulary throughout.
Frequently asked questions
What is the difference between BNB and BNB Chain?
BNB is the coin and BNB Chain is the family of networks it belongs to. That family contains three separate networks: BNB Smart Chain for applications, opBNB for cheap high-volume transactions, and Greenfield for storage. All three charge their fees in BNB, and each keeps its own balances, so coins have to be bridged across before they can pay a fee on a different one.
Is BSC the same as BNB Smart Chain?
Yes, BSC is simply the abbreviation, and it stands for Binance Smart Chain, the network's original name before the 2022 rebrand to BNB Smart Chain. Both refer to the same network, identified by wallets as chain ID 56, and the abbreviation remains in wide use across wallets and documentation.
What is WBNB and do you need it?
WBNB is BNB packaged as a standard token so that contracts can handle it like any other. Decentralized exchanges usually wrap and unwrap it for you without asking, so most people hold it briefly without noticing. It is worth the same as BNB and converts back one for one, though it has to be unwrapped before it can pay a transaction fee.
What are Cabinet and Candidate validators?
They are the two tiers of the 45 validators elected each day on BNB Smart Chain. The 21 with the most stake behind them are Cabinet validators and produce most of the blocks, while the next 24 are Candidates and produce fewer. The ranking is redone daily, so validators move between the tiers as stake shifts.
What does a bnb1 address mean?
It belonged to BNB Beacon Chain, the network retired in December 2024. Current BNB addresses begin with 0x, in the same format as Ethereum. A bnb1 address belongs to a network that stopped producing blocks, so coins sent there have nowhere to arrive, and any such address in an old note or contact list should be treated as unusable.
Why do spot and perpetual pairs get written differently?
It is a convention that lets you tell them apart at a glance. Spot pairs carry a slash, as in BNB/USDT, and perpetual contracts do not, as in BNBUSDT. Buying spot leaves you holding the coin, while a perpetual tracks the price without ever holding it, so only the first can be withdrawn to a wallet.
