BNB Chain releases technical roadmap for the second half of 2026, plans to double mainnet throughput again

Foresight News reports that BNB Chain has released its technical roadmap for the second half of 2026. In the upcoming period, BNB Chain will advance three core objectives: doubling mainnet throughput again (with a long-term goal of a tenfold increase); reducing interference between applications through advanced resource isolation mechanisms; and optimizing the gas fee structure to lower access costs for enterprise users. Specific measures include implementing BEP-675, introducing dedicated channel solutions, promoting parallel execution based on BAL, and fine-tuning gas fees for specific industries.

BNB Chain stated that in the first half of 2026, BSC reduced block intervals from 750 milliseconds to 450 milliseconds, decreased memory finalization time from 1,125 milliseconds to 650 milliseconds, and improved benchmark throughput from approximately 2,800 TPS to 5,200 TPS (about 400 MGas/s). The BSC Rust client achieved full compatibility with Reth v2.0, doubling performance.

In addition, BNB Chain announced it is developing a next-generation L1 architecture with targets including over 100,000 TPS, transaction pre-confirmation under 50 milliseconds, a TxStream mechanism without a public mempool, on-chain governance for PriorityLane to reserve block space, and native privacy transaction features at the protocol layer. This architecture is scheduled to launch its testnet by the end of 2026 and the mainnet in early 2027. BNB Chain will also continue advancing quantum-resistant security research, exploring hybrid quantum-resistant solutions and pathways for integrating account abstraction.
