BNB blockchain
Formerly: Binance Smart Chain (BSC)
Launched: 2020 by Binance (now decentralized under BNB Chain governance).
Native Token: BNB (used for fees, staking, and governance).
Consensus: Proof-of-Staked Authority (PoSA) — hybrid of PoS and DPoS.
TPS: ~2,200 (faster/cheaper than Ethereum but more centralized).
2. Key Features:
EVM-Compatible: Supports Ethereum tools (MetaMask, Hardhat, etc.).
Low Fees: ~$0.05–$0.30 per transaction (vs. Ethereum’s $1–$50).
Dual-Chain:
BNB Smart Chain (BSC): For smart contracts (Solidity).
BNB Beacon Chain: Handles staking/governance (now deprecated in favor of BSC).
Interoperability: Bridges to Ethereum, Polygon, etc.
Recent Upgrades (2023–2024)
zkBNB Testnet: Privacy-focused ZK-Rollups for scaling.
Greenfield: Decentralized storage network (competes with Filecoin).
BNB Chain Fusion: Merging Beacon Chain into BSC for efficiency.
Enhanced Security: Hard forks to prevent exploits (e.g., Venus hack patches).
BNB Tokenomics (2024):
Max Supply: 168M BNB (burn mechanism reduces supply).
Use Cases:
Pay transaction fees.
Staking (APR ~5–10%).
Governance voting.
Burns: Quarterly burns based on BSC usage (latest: ~2M BNB burned).
