What is BNB Chain Fermi Hard Fork?

of BNB chainfermi hard fork is the latest upgrade to the BNB Smart Chain (BSC) network. Its main goal is to improve speed and efficiency by: 40% reduction in block time — from 750 ms to 450 ms.

In practical terms, this means that transactions on the BNB Smart Chain will be confirmed faster, the network can handle more activity, and the user experience will be smoother.

upgrade known as Version 1.6.2also includes the following improvements: Miners, MEV (Maximum Extractable Value), and overall performance. I will introduce 5 new BEPs (BNB Evolution Proposals) Aimed at optimizing block generation, stability, and developer support.

of Testnet activation Because Fermi set to November 10, 20252:25 a.m. (UTC). of Mainnet launch date Will be confirmed after complete completion stress testThis allows developers and community members to validate upgrades under real network conditions.

Why the Fermi hard fork matters

BNB Chain’s Fermi upgrade represents an important step in the network’s continued push towards faster transaction processing and better validator coordination.

By shortening the block interval to 450ms, BNB Chain will be one of the fastest major blockchains in operation — ahead of several major Ethereum-compatible chains.

Main goals of the Fermi hard fork:

• Reduced blocking time For faster transaction confirmation.
• higher throughput To increase transaction capacity.
• Optimized MEV processing To improve fairness and efficiency.
• Improved block propagation Reduce latency between validators.
• Improved stability When transaction load is high.

These technical improvements enable BSC to handle increased traffic without compromising decentralization or performance.

Technical Core: BEP introduced in Fermi

Introducing the Fermi Hard Fork 5 new BEPs (BNB Evolution Proposals) Define technical structure and functionality.

1. BEP-590: Extended voting rules to quickly stabilize finality

This proposal proposes to improve the way validator votes are counted in the fast finality protocol of the BNB Smart Chain. The goal is to increase the stability and reliability of block confirmations even when the network faces delays and issues, while also allowing the chain to safely support shorter block times.

2. BEP-619: Short block interval phase 3 (0.45 seconds)

BEP-619 implements the key features of the Fermi upgrade and reduces block times. 0.45 seconds. This represents the third phase of BNB Chain’s continued efforts to reduce intervals while maintaining validator performance and network synchronization.

3. BEP-592: non-consensus-based block-level access list

This BEP adds Block-level access list (BAL) — A type of metadata attached to each block. BAL enables nodes to: Preload storage data in advance Importing blocks. By caching commonly used accounts and storage slots, Speed ​​up block processing and Improve overall network performance.

4. BEP-593: Incremental snapshot

This update introduces: Incremental state snapshotallows nodes to store blockchain data more efficiently. Memory usage is reduced, synchronization is faster, and nodes run lighter and more stable.

5. BEP-610: EVM super instruction implementation

BEP-610 focuses on: Ethereum Virtual Machine (EVM) optimization By adding a “super instruction”. These are pre-compiled EVM operations that make smart contracts run faster and consume fewer resources.

Together, these five BEPs improve performance on multiple levels, from transaction speed to validator stability to contract enforcement.

New features in version 1.6.2

In addition to major BEP upgrades, Version 1.6.2 The BNB Smart Chain software introduces several optimizations designed for miner and MEV processing.

This update focuses on:

• Faster block propagation Between validators.
• Reduced waiting time With transaction broadcast and block finalization.
• More transparent MEV management To ensure fairness in transaction order.
• Increased network throughput Supports large scale dApps, DeFi Activities.

These improvements will enhance the chain’s operational performance, especially under high transaction volumes common in decentralized finance and gaming applications.

The road to mainnet: testing and validation

of Fermi hard fork test net Live continues November 10, 2025community members and developers can participate in performance testing.

The BNB Chain team is stress test — simulate high transaction load — before checking Mainnet activation date.

This gradual rollout allows developers to identify and resolve potential issues early. It also gives verifiers time to upgrade nodes, adjust configurations, and test new consensus rules.

Once the testnet has been validated and performance metrics meet expectations, the Fermi hard fork will be released. BNB Smart Chain Mainnet.

Background: Continuous optimization since Lorenz

The Fermi upgrade is part of a long-running series of performance improvements to the BNB chain.

• lorenz hard fork: Reducing block time 3 seconds to 1.5 seconds Validator stability has also been improved.
• maxwell hard fork: Block time has been further reduced 0.75 seconds.
• pascal hard fourk: Enhancement Ethereum compatibility with support for EIP-7702 smart contract wallet and BLS12-381 encryption.

Now, with Fermi, block times are once again reduced. 750ms to 450ms — Responsiveness has improved even further.

Each upgrade builds on and improves on the previous one Speed, Scalability, and Ethereum InteroperabilityThis is important for both users and developers active in the BNB ecosystem.

Why is reducing block time important?

Reducing block times improves almost every aspect of blockchain usability.

The main benefits are:

• Faster transaction confirmation: Users will see their balances updated almost instantly.
• Improving network responsiveness: Smart contracts and dApps react more quickly.
• Improving validator efficiency: Validators process data faster and maintain network health.
• Great scalability: The network can handle more concurrent transactions without becoming congested.

These benefits are especially valuable if: DeFi Platform, GameFi Project, NFT Marketplacetransaction speed directly impacts user experience.

Developer influence and ecosystem growth

For developers, Fermi simplifies building and deploying scalable applications on the BNB Smart Chain.

With faster finality and optimized EVM execution, dApps can now perform complex operations with reduced latency and gas overhead.

With improved handling of MEVs, Fair competition between validators and Transparent transaction orderinga key element for a healthy on-chain economy.

Fermi Hard Fork strengthens BNB Chain’s position as the leading EVM-compatible network by aligning technical efficiency with open development.

conclusion

of BNB Chain Fermi Hard Fork is a focused technology upgrade designed to make the BNB Smart Chain faster, more efficient, and more reliable.

By reducing block times from 750ms to 450ms, adding five new BEPs, and improving MEV processing and validator performance, Fermi strengthens the network’s ability to process more transactions while maintaining both decentralization and security.

This upgrade follows BNB Chain’s consistent strategy of incremental and visible improvements that prioritize speed, stability, and scalability for both users and developers.
