Overview
- BNB Chain, which announced the plan Wednesday, published a roadmap calling for a public testnet in late 2026 and a mainnet target in early 2027 with goals of under 50 millisecond pre-confirmation and over 100,000 transactions per second.
- The design removes the public mempool and uses direct transaction streaming to block leaders to lower latency and reduce front-running and sandwich attacks during execution.
- The roadmap also lists protocol-level features such as reserved transaction lanes, account abstraction, native privacy, gas sponsorship, and execution-layer optimizations like just-in-time compilation.
- BNB Chain’s claims build on recent upgrades that cut BSC block times to about 0.45 seconds, but the firm’s aggressive latency and throughput targets remain unproven until testnet and mainnet benchmarks are published.
- BNB says the new L1 will run alongside BSC, opBNB and Greenfield to serve AI trading use cases, a move that leaves ecosystem activity growing even as BNB price trades near key support levels.
