Binance Coin (BNB) is the cryptocurrency created by Binance, the world's largest cryptocurrency exchange by trading volume. Launched in 2017, BNB started as a utility token on Ethereum but now powers its own blockchain, the BNB Smart Chain (BSC). Known for fast transactions and low fees, BSC has emerged as a leading Ethereum alternative, supporting smart contracts and decentralized applications (dApps).
History of BNB and BSC
BNB was initially launched as an Ethereum-based ERC-20 token in 2017, offering trading fee discounts on Binance. In 2019, Binance migrated BNB to its native Binance Chain. By 2020, Binance introduced Binance Smart Chain (BSC)—a scalable blockchain for decentralized apps—later rebranded as BNB Smart Chain in 2022.

FAQ
1. Where can I buy BNB?
BNB is available on Binance, OKX, KuCoin, and other exchanges. Withdraw to a non-custodial wallet like Trezor for security.
2. What’s the difference between BEP-20 and ERC-20?
Both are token standards—BEP-20 runs on BSC, while ERC-20 operates on Ethereum. BEP-20 offers lower fees.
3. How decentralized is BNB Smart Chain?
BSC trades some decentralization for speed, with Binance operating key validators. Compare this to Ethereum’s 700,000+ validators.
4. Can I store BNB on a hardware wallet?
Yes! Trezor Suite supports BNB and BEP-20 tokens securely.
5. Why does BNB burn tokens?
Burns reduce supply, increasing scarcity and potential value over time.
