BNB Chain is moving to significantly improve network speed and reliability with the Fermi hard fork, which goes live this Wednesday. The upgrade is designed to reduce confirmation delays and strengthen transaction finality, positioning BNB Smart Chain among the fastest major EVM-compatible networks.
With the Fermi upgrade, BNB Smart Chain block times drop from 0.75 seconds to 0.45 seconds, nearly halving how quickly new blocks are produced. This change is expected to push transaction finality to around one second, even during periods of heavy network usage. The upgrade completes the final phase of the chain’s short block interval roadmap, focusing on performance rather than cosmetic changes.
Fermi refines consensus rules to ensure validators remain tightly synchronized despite faster block production. The update introduces stricter propagation and fast-finality voting parameters, reducing the risk of delayed confirmations when activity spikes. The goal is to deliver faster confirmations without sacrificing reliability or predictability.
BNB Chain was among the busiest in 2025 acording to Nansen;
The upgrade is tailored for latency sensitive use cases, including onchain trading, real-time DeFi protocols, and interactive blockchain games. Most decentralized applications will not require code changes, though projects dependent on precise block timing may need adjustments.
In 2025 BNB Chain ranked among the busiest blockchains by transaction volume. By targeting sub-second finality while maintaining EVM compatibility, Fermi strengthens the network’s position as a high-performance platform built for scalable, real-world blockchain activity.
