BNB Chain 2026 Technical Roadmap: Further Reduce Gas Fees, Achieve 20,000 TPS with Sub-Second Finality

On December 30, BNB Chain unveiled its 2026 Technology Roadmap, retaining its dual-client approach: a Geth-based client to anchor stability for validator compatibility and operational reliability, and a Reth-based client as a high-performance engine for full nodes, archive nodes, and future validator support. Key 2026 milestones include: - Sub-second transaction finality with 20,000 TPS; - Further gas fee reductions via software optimization; - Advanced consensus and network latency upgrades to drive finality into deeper sub-second ranges. Between 2026 and 2028, BNB Chain aims to become a next-generation trading chain capable of meeting extreme performance demands, with core objectives: - ~1 million TPS, requiring sustained execution capacity of ~20 GGas per second; - Near-instant transaction confirmations, with an optimal target of 150ms; - A hybrid on-chain/off-chain computation architecture featuring execution and validation proofs; - Enhanced decentralization via improved validator models and fault tolerance; - Top-tier security and production-grade reliability.
