BNB Chain schedules the Fermi hard fork for November 10, 2025 on testnet, reducing BSC block times to 450 ms, with mainnet deployment pending stress test results.
BNB Chain has announced the Fermi hard fork for its BSC network, aiming to reduce block intervals from 750 milliseconds to 450 milliseconds. The upgrade will activate on the testnet on November 10, 2025. Mainnet activation will depend on the outcome of comprehensive stress testing to ensure stability. The initiative complements previous acceleration efforts, such as opBNB’s Fourier hard fork, and continues BNB Chain’s push for faster transaction processing.
