BNB Chain
Ethereum-compatible blockchain.
About BNB Chain
BNB Chain is an Ethereum-compatible blockchain ecosystem designed for high-performance decentralized applications (dApps) and Web3 services. Originating from Binance Chain and Binance Smart Chain, it has evolved into a multi-chain architecture supporting DeFi, NFTs, gaming, and AI solutions. As one of the largest blockchain networks by transaction volume, BNB Chain processes over 2,000 transactions per second (TPS) with sub-second finality and gas fees under $0.01.
Key components:
- BNB Smart Chain (BSC): EVM-compatible execution layer for smart contracts
- opBNB: Optimistic rollup Layer-2 scaling solution
- BNB Greenfield: Decentralized data storage network
- zkBNB: Zero-knowledge proof-powered scalability solution
The chain hosts 1,400+ active dApps across 10+ verticals and maintains $4.8B+ in total value locked (TVL), positioning it as a leading platform for Web3 mass adoption.
Technology
BNB Chain employs a hybrid Proof-of-Staked Authority (PoSA) consensus mechanism combining:
- 29 active validators
- 4-second block times
- 100M gas limit per block
Technical stack innovations:
- EVM++: Enhanced Ethereum Virtual Machine with native oracle support
- BAS (BNB Application Sidechain): Customizable L2/L3 chains
- BEP-367: Modular blockchain upgrade framework
- AI-ready infrastructure: On-chain ML model execution capabilities
The architecture solves blockchain trilemma challenges through:
- Horizontal scaling via opBNB (4,000-5,000 TPS capacity)
- Cross-chain interoperability with Binance Bridge
- Gas fee optimization algorithms reducing costs by 90% vs Ethereum
Key Features
- High-performance execution: 2,000+ TPS with 0.5s block confirmation
- EVM+ compatibility: Full support for Solidity/Vyper with BSC-specific optimizations
- Multi-chain ecosystem: Integrated L1, L2, and storage solutions
- AI integration layer: Native support for AI agent frameworks through custom plugins
- Developer suite: $10M+ hackathon fund, faucet services, and debug tools
- Decentralized governance: On-chain voting for protocol upgrades
- Institutional-grade security: Formal verification for smart contracts
Integration with Eliza
BNB Chain provides official ElizaOS plugin (GitHub) enabling:
// AI Agent Smart Contract Template
contract ElizaBNB {
function executeAIJob(
address agent,
bytes memory input
) public payable returns (bytes memory) {
return ElizaOSPlugin.execute{value: msg.value}(agent, input);
}
}
Technical synergies:
- Direct access to BSC/BEP-20 token operations
- AI-driven DeFi strategies via Venus Protocol integration
- Automated NFT minting through BakerySwap APIs
- Real-time gas price prediction models
Use cases include:
- AI-controlled liquidity pools
- NFT generative art engines
- Risk-adjusted yield optimizers
- Cross-chain arbitrage bots
