BNB Smart Chain has scheduled the activation of its Fermi hard fork on mainnet for Jan. 14, following nearly two months of testing on the network’s testnet.

The upgrade will reduce the block interval from 750 milliseconds to 250 milliseconds, aiming to support time-sensitive applications that require sub-second block confirmations. According to technical documentation from the BNB community, the change is designed to improve performance for use cases such as payments and advanced DeFi applications that depend on faster execution.

Fermi also introduces extended voting parameters to compensate for communication delays between nodes caused by the shorter block times. In addition, the upgrade includes a new indexing mechanism that allows users to download only specific portions of the ledger instead of the full block history, reducing computing and storage requirements.

BNB Smart Chain currently processes around 222 transactions per second, although its theoretical maximum throughput is significantly higher. The network has seen steady growth in active addresses, bringing it closer to other high-throughput layer-1 blockchains. The Fermi upgrade reflects a broader push by blockchain networks to increase throughput and reduce latency in order to better support decentralized applications.
