BNB Chain is set to increase its block gas limit to 1G in the latter half of 2025, significantly enhancing its transaction processing capabilities. This upgrade will enable the network to support 5,000 transactions per second, marking a tenfold increase in throughput. The new generation of BNB Chain aims to achieve a final confirmation time of less than 150 milliseconds and over 20,000 transactions per second (TPS). The upgrade includes several optimizations, such as a new Rust client for faster synchronization and higher throughput, a super instruction set to simplify complex smart contract execution, and an optimized StateDB to accelerate the storage and access of large on-chain data. Additionally, built-in privacy functions will be integrated at the protocol layer, further enhancing the network's capabilities.
