BNB Chain Releases 2026 Roadmap: Moving Towards 20,000 TPS and Sub-Second Finality

BNB Chain announces its 2026 technical roadmap. The official statement indicates that 2025 is a key milestone year for BNB Chain, with the network achieving zero downtime operation throughout the year under real high-load conditions, while transaction activity, stablecoin market cap, and real-world assets (RWA) continue to grow. Based on practical experience over the past year in reliability, speed, cost efficiency, and fairness, BNB Chain has clarified its technological evolution direction for 2026.
In 2025, BNB Chain shortened block times from 3 seconds to 0.45 seconds through multiple hard forks such as Pascal, Lorentz, Maxwell, and Fermi, with deterministic finality time reduced to 1.125 seconds, and network bandwidth increased to 133 million Gas per second. The network handled a peak daily throughput of approximately 5 trillion Gas, maintaining stable operation during Meme coin trading peaks and BNB all-time highs. During the same period, network TVL grew by 40.5% year-over-year, with a maximum of 31 million transactions per day, stablecoin market cap peaked at about $14 billion, and RWA assets surpassed $1.8 billion.
The roadmap shows that in 2026, BNB Chain will continue to use BSC as a highly optimized EVM transaction chain, advancing a dual-client strategy: ensuring stability with the Geth client and employing a Reth-based client as a high-performance engine. Core goals include achieving 20,000 TPS, sub-second finality, and further reducing Gas costs through software layer optimizations. Additionally, the network will introduce higher-performance execution engines, parallel execution, and parallel storage capabilities to address the ongoing growth of state size.
At the infrastructure level, BNB Chain will continue to improve scalable database architecture to mitigate state bloat through multi-layer sharding and distributed processing; at the application layer, it will launch privacy frameworks and AI middleware to reduce development complexity for advanced applications. In longer-term plans, BNB Chain also disclosed that it is designing the next-generation transaction chain, aiming for nearly one million TPS and millisecond-level confirmation between 2026 and 2028, with a hybrid on-chain/off-chain computing architecture to enhance overall decentralization and security.
The official summary states that this roadmap is based on real production environment experience, with the core goal of ensuring long-term sustainability of performance, reliability, and fairness while continuously expanding network scale. $BNB
