BNB Chain is one of the most active blockchain ecosystems in the world, processing millions of transactions daily with low fees and fast confirmation times.
BNB Chain Architecture
BNB Smart Chain (BSC)
BNB Smart Chain is an Ethereum-compatible blockchain that supports smart contracts and decentralized applications. It uses a Proof of Staked Authority (PoSA) consensus mechanism with 21 validators, enabling fast block times of approximately 3 seconds and transaction fees typically under $0.10 USD.
opBNB – Layer 2 Scaling
opBNB is a Layer-2 solution built on BNB Smart Chain using optimistic rollup technology. It offers even lower fees and higher throughput for applications that need to scale beyond BSC's capabilities.
BNB Use Cases
- Transaction Fees: BNB is used to pay for gas on BSC and opBNB
- Trading Fee Discounts: BNB holders get discounts on Binance exchange fees
- DeFi: BNB is used in yield farming, liquidity pools, and lending on PancakeSwap and other protocols
- Governance: BNB stakers participate in validator selection and on-chain governance
- Launchpad: BNB is required to participate in Binance Launchpad token sales
BNB Token Burns
Binance conducts quarterly auto-burn events that reduce the total BNB supply using a formula based on BNB price and block production, creating a deflationary mechanism that reduces supply over time.
