BNB Chain Develops New Layer 1 Blockchain for Agentic Trading, Targets Sub-50ms Preconfirmation

BNB Chain is developing a new Layer 1 blockchain focused on agentic trading and has released its first detailed architecture information after months of research and development. According to Odaily, BNB Chain’s technical roadmap for the second half of 2026 shows the new chain will run in parallel with the existing BNB Chain ecosystem. BNB Chain said the new network is designed to achieve transaction preconfirmation in under 50 milliseconds, aiming to provide an execution experience similar to centralized exchanges while maintaining on-chain self-custody and transparency. On the technical side, BNB Chain said the new chain will remove the traditional public mempool and introduce a transaction transmission mechanism called “TxStream.” Under this design, transactions are sent directly to block producers to reduce latency and limit certain forms of MEV extraction, including sandwich attacks.
