BNB Chain plans to launch a new Layer 1 blockchain, with mainnet expected to go live in 2027

Odaily reported that BNB Chain is developing a new Layer 1 blockchain designed for Agentic Trading, releasing the first detailed architectural information after months of research and development. According to BNB Chain's disclosed technical roadmap for the second half of 2026, the new chain will run in parallel with the existing BNB Chain ecosystem, targeting transaction preconfirmation times of less than 50 milliseconds. The goal is to deliver an execution experience close to that of centralized exchanges (CEX) while retaining the advantages of on-chain self-custody and transparency.

In terms of technical architecture, the new chain will remove the traditional public mempool and introduce a transaction transmission mechanism called "TxStream," which directly sends transactions to block producers to reduce latency and minimize MEV extraction behaviors such as sandwich attacks.
