Overview
- BNB Chain publicly unveiled the new purpose‑built Layer‑1 on July 8, 2026 and set a public testnet for late 2026 with a target mainnet launch in early 2027.
- The design replaces the public mempool with a TxStream that routes transactions directly to block leaders to lower latency and reduce visible front‑running opportunities.
- Official targets include transaction preconfirmation under 50 milliseconds, initial throughput above 100,000 transactions per second, reserved blockspace called PriorityLane, account abstraction, native privacy features, and research into quantum‑resistant protections.
- BNB Chain projects a longer‑term ‘hybrid compute’ architecture that could scale toward roughly 1,000,000 TPS between 2026 and 2028 but those performance and security claims remain unproven until testnet benchmarks and audits.
- Market response has been muted with BNB trading around $560, and the new chain will run alongside BSC, opBNB and Greenfield as part of a multi‑pillar strategy that aims to attract AI agents and institutional trading while preserving existing apps and TVL.
