BNB Chain Targets AI Trading With New High-Speed Layer 1 Blockchain

• BNB Chain is building a high-speed Layer 1 to give AI trading agents near-instant onchain execution.
• The new network removes the public mempool to reduce front-running and speed up transaction processing.
• BNB Chain plans a 2027 mainnet while expanding DeFi, stablecoin activity, and ecosystem growth.

BNB Chain is developing a new Layer 1 blockchain designed for AI-powered trading agents, as the network looks to make onchain trading faster and more competitive with centralized exchanges. The project is expected to enter testnet before the end of 2026, with a mainnet launch planned for early 2027.

The new blockchain is designed to process more than 100,000 transactions per second, deliver transaction confirmation in under 50 milliseconds, and finalize blocks in less than a second. The upgrade aims to narrow the speed gap between decentralized and centralized trading platforms, although BNB Chain said traders using specialized infrastructure on centralized exchanges will still benefit from faster execution.

New Architecture Targets Faster Trading

BNB Chain said the new blockchain will eliminate the public mempool, where transactions usually wait before they are processed. Instead, a feature called TxStream will send transactions directly to the validator handling the next block. The network said this approach should speed up processing and make it harder for traders to exploit pending transactions through front-running.

Chief Technology Officer David Z said the goal is to give most users a trading experience closer to that of a centralized exchange without requiring them to hand over control of their assets. “For co-located HFT, a CEX still wins today. For everyone else, this is the CEX experience without the custodial risk,” he said in an exclusive shared with an industry source. He added that rotating validators every 200 milliseconds makes it more difficult to manipulate transactions while improving transparency.

The roadmap also includes a feature called PriorityLane, which sets aside block space for time-sensitive transactions, including oracle updates, cross-chain bridge transfers, and liquidations. BNB Chain said those allocations will be handled directly onchain.

Focus Shifts to Execution Performance

David Z said the biggest challenge for blockchains is no longer reaching agreement on transactions but processing them fast enough. To address that, BNB Chain is using software optimizations, parallel processing, and a new storage system based on LtHash to improve performance while keeping the network compatible with the Ethereum Virtual Machine.

BNB Chain also plans to launch an official bridge linking the new Layer 1 blockchain with BNB Smart Chain. David Z said the goal is to expand the overall BNB Chain ecosystem rather than shift activity from one network to another. The company expects the two networks to serve different purposes instead of competing for the same users and liquidity.

Quantum Security Joins Expansion Plans

BNB Chain is also researching ways to protect the network from future quantum computing threats through hybrid cryptography and account abstraction. However, Chief Technology Officer David Z said the industry has yet to find a complete solution for migrating blockchains to quantum-resistant security. He added that the risk of attackers collecting encrypted data today and decrypting it in the future remains a challenge across the industry.

Beyond the technology roadmap, ecosystem activity has continued to grow. Blockchain analytics platform Iko Web3 said BNB Chain has recorded increases in decentralized finance activity, stablecoin use, active wallets, and total value secured on the network. 

Meanwhile, CoinMarketCap data showed BNB trading at $563.62 as of publication, with more than $1.17 billion in trading volume over the past 24 hours despite a 2.49% price decline during the same period.
