BNB Chain developers officially released the long-awaited Fermi Hardfork today, November 3rd.
This important update aims to improve network responsiveness and speed.
Specifically, it reduces blocking time from 750ms to 450ms, increasing transaction speeds by 40%.
Once version 1.6.2 goes live, the network will process and confirm transactions even faster.
This promises users a more efficient and streamlined experience when interacting with exchanges, wallets, and decentralized applications (dApps) within the BNB Smart Chain ecosystem.
Fermi Hardfork comes less than a month after the chain adopted an ultra-low gas price model.
According to X’s official post today:
This upgrade reduces the block interval from 750ms to 450ms, significantly improving transaction efficiency, network throughput, and overall performance. The shorter the blocking time, the faster the processing and the smoother the user experience.
Fermi Hardfork releases are now available on the BSC network. This upgrade reduces the block interval from 750ms to 450ms, significantly improving transaction efficiency, network throughput, and overall performance. Shorter block times allow for faster processing,

The announcement revealed that Fermi Hardfork testnet activation will take place on November 10th, with mainnet rollout TBA (TBD).
Nevertheless, the entire upgrade will be subject to stress tests to measure network performance during intense activities.
This approach ensures reliability and stability after deploying Fermi on the BSC mainnet. Meanwhile, the team invited enthusiasts to participate in testing and validation.
Other features in v1.6.2

In addition to key Fermi features, the latest deployment of BNB Chain introduces a variety of significant improvements that enhance the BNB Smart Chain network.
First and foremost, the v1.6.2 release includes MEV (Maximal Extractable Value) and miner optimizations to improve performance and ensure transparent transactions.
This update also improves the overall performance of the chain by improving block propagation, reducing latency, and increasing throughput.
Such changes contribute to an efficient and more balanced blockchain.
As cryptocurrencies gain mainstream acceptance, this is essential to sustain increasing transaction volumes without compromising user experience.
Why is the Fermi upgrade important?

Fermi Hardfork reduced block times from 750ms to 450ms, making the BNB chain one of the most efficient and fastest networks in the blockchain world.
Its speed, scalability, and stability enable developers to build innovative solutions while providing users with near-instantaneous transaction settlement.
BNB community watches as Fermi hard fork progresses to testing.
The promised changes aim to quickly transform the way users trade assets, deploy smart contracts, and interact with decentralized applications on the BNB Smart Chain.
Mainnet occurs after stress testing and feedback evaluation and marks a new stage in the evolution of the BNB Chain.
In other related updates, Native BNB is trading at $1,020 after dropping more than 5% of its value in the past 24 hours as the bear market triggered further widespread market declines.
