BNB Chain launches layer-1 blockchain for 100K TPS AI trading
In brief
- BNB Chain develops layer-1 blockchain for high-frequency trading and AI agents
- Network targets 100,000+ TPS with sub-50ms preconfirmations and removes public mempool
- Public testnet end of 2026; mainnet launch planned for early 2027
- Design eliminates front-running by streaming transactions directly to block leader
- New chain runs alongside existing BNB Smart Chain ecosystem
Speed and security through mempool removal
The new chain removes the public mempool, streaming transactions directly to the block leader. This design lowers latency and prevents front-running by eliminating the public queue where pending trades are visible to all participants. The approach addresses a core pain point in decentralized finance: the ability for sophisticated traders to observe and exploit pending orders before they settle.
BNB Smart Chain currently holds roughly $5 billion in total value locked, making it one of the largest Ethereum alternatives. The existing chain has already shown performance gains. During the first half of 2026, block times fell to 450 milliseconds from 750, while benchmark throughput rose to about 5,200 transactions per second from roughly 2,800.
The roadmap targets transaction preconfirmations under 50 milliseconds, throughput above 100,000 transactions per second and sub-second block finality. David Z, BNB Chain's chief technical officer, said the next phase of development focuses on execution rather than consensus.
Execution optimization and emerging use cases
The new network will use execution-layer techniques such as just-in-time compilation, which compiles code as it runs. These optimizations aim to squeeze more performance out of the hardware without sacrificing security.
The roadmap reserves blockspace for services such as oracles, liquidations and cross-chain bridges, alongside native privacy, account abstraction, gas sponsorship, transaction batching, scheduled execution and passkey signing. This infrastructure targets both traders seeking speed and developers building autonomous agents.
The timing aligns with growing interest in AI-native blockchains. Coinbase introduced accounts designed for AI agents last month, reflecting broader momentum in the sector.
The new chain will run alongside the existing BNB Chain ecosystem rather than replace it. BNB Chain is separately researching quantum-resistant security, aiming to let users adopt quantum-safe protection without changing wallet addresses or disrupting existing applications.
