The BNB Smart Chain is set to undergo a significant upgrade in early 2026 with its Fermi hard fork, aimed at dramatically reducing block times and enhancing the network’s capacity for real-time applications. This upgrade is a response to ongoing efforts in the blockchain sector to improve performance and compete with traditional financial systems.
Major Reduction in BNB Smart Chain Block Times
According to a press release on GitHub, the Fermi hard fork will activate on the BNB Smart Chain mainnet on January 14, following approximately two months of real-time testing on the Fermi testnet. A key feature of this upgrade is a substantial cut in block times, which will decrease from 750 milliseconds to just 250 milliseconds.
This change securely positions the BNB Smart Chain in the sub-one-second block time category, catering specifically to applications that require quick confirmations, such as high-frequency trading tools and real-time gaming platforms. While shorter block intervals can present challenges, such as network communication and validator coordination, the Fermi upgrade incorporates extended voting parameters to mitigate these delays.
These adjustments aim to maintain consensus stability even as blocks are produced three times more swiftly than before, allowing the network to handle transactions faster without compromising accuracy or security—a balance that many layer-1 blockchains struggle to achieve.
Currently, the BNB Smart Chain is one of the most utilized layer-1 networks, processing approximately 165 transactions per second. In comparison, networks like Solana manage up to 799 transactions per second. With the Fermi hard fork, the BNB Smart Chain aspires to enhance its block production speed and reduce confirmation delays, particularly during peak hours, which is crucial for DeFi applications.
The upgrade also introduces a new partial ledger indexing mechanism, allowing users and node operators to sync only the necessary data without downloading the entire historical ledger. This will significantly decrease storage and computational needs, facilitating easier node operation and network interaction.
Experimental Progress Signals Future Potential
Moreover, the Fermi hard fork builds on recent experimental efforts aimed at enhancing execution performance, notably through the client version BAL7928 v1.6.4 launched late last year. This experimental version implements a non-consensual block access list (BAL) based on EIP-7928, similar in design to BEP-592.
Rather than altering consensus rules, BAL data is shared through peer-to-peer block propagation messages, enabling more efficient transaction execution when data is available. In local test environments, the BAL implementation has demonstrated an average performance improvement of about 18.6% in million gas per second.
Developers acknowledge, however, that actual benefits rely on widespread network adoption, as nodes can only leverage performance enhancements when their peers also support the feature. As competition among layer-1 blockchains intensifies, these updates position the BNB Smart Chain to better serve high-demand applications and an increasing user activity.
This could reignite interest in Binance Coin (BNB), potentially leading to a rebound after a three-month decline that saw it drop to approximately $833.48 from its peak of $1,369.99 in October 2025.
