BNB Chain to build new Layer 1 optimized for AI agent trading

BNB Chain has announced it is building a new Layer 1 blockchain optimized for AI agent-based trading. According to its technology roadmap for the second half of 2026, the new chain aims to achieve execution speeds comparable to centralized exchanges (CEX) while allowing users to maintain self-custody of their assets. The goal is to reduce transaction pre-confirmation times to under 50 milliseconds (ms). Notably, it will introduce a "TxStream" architecture that eliminates the public mempool to prevent front-running. In this structure, transactions are sent directly to the block producer, fundamentally blocking sandwich attacks. Block producers will rotate every 200ms to minimize the risk of monopoly or censorship. The chain is being developed to target a throughput of over 100,000 TPS, incorporating features like parallel execution. The chain is scheduled to launch its testnet by the end of 2026, with a mainnet release planned for early 2027.
