BNB Chain is developing a new $Layer 1 blockchain tailored for agentic trading and has released the first detailed architectural information following several months of R&D. According to BNB Chain’s technical roadmap for H2 2026, the new chain will run in parallel with the existing BNB Chain ecosystem and aims to achieve sub-50-millisecond transaction preconfirmations, delivering an execution experience comparable to that of centralized exchanges (CEXs) while preserving the benefits of on-chain self-custody and transparency.
Technically, the new chain will eliminate the traditional public mempool and introduce a transaction transmission mechanism called “TxStream,” which sends transactions directly to block producers to reduce latency and mitigate MEV extraction behaviors such as sandwich attacks. (The Block)[Odaily]
