The BNB Chain team has presented an updated roadmap for the second half of 2025, announcing a significant increase in the gas limit per block to 1G, which is ten times the current figure. This will enable the network to support up to 5000 swaps on decentralized exchanges (DEX) per second, significantly enhancing the system’s throughput.

New technological solutions and performance optimization
According to the developers, a new client built in Rust, based on Ethereum Reth, has been created to achieve these goals. It provides significant improvements in memory handling and high performance, allowing for a 10-20 times increase in network throughput. One of the key innovations will be the implementation of Super Instructions – combined standard operations to optimize complex transactions, particularly DEX swaps and token launches. They are expected to accelerate the processing of complex operations in the network as early as 2025.
Infrastructure changes and enhanced privacy
Particular attention in the update has been given to optimizing StateDB – a cache that combines elements of EVM and storage in BSC. Since approximately 30% of the execution time of smart contracts is spent on state access, improving StateDB will significantly speed up data processing.
In 2026, developers plan to implement a new architecture that will ensure instant transactions and privacy by default. Among the main changes, transaction confirmations in less than 150 milliseconds, processing over 20,000 transactions per second for DeFi projects, and the introduction of privacy at the protocol level are also noted.
It was also stated in the announcement that BNB Chain aims to support a 10-20 times higher throughput. A new client built in Rust, based on Ethereum Reth, has been developed that “significantly improves memory handling and provides high performance.”
It is worth noting that previously, BNB Chain had already accelerated block processing to 0.8 seconds through the implementation of the Maxwell hard fork, which was the first step towards a large-scale network upgrade.
