BNB Chain Launches BEP-640: A New Strategy for Network Stability and Performance

The BNB Smart Chain faces challenges of rapid growth, and to keep the network stable as it expands, BEP-640 has been introduced as a new resource management tool. This proposal not only enhances stability but also offers a flexible approach that allows each validator to choose according to their needs.

What Exactly is BEP-640 and How Does It Improve Stability?

BEP-640 is an optional gas limit mechanism designed for off-chain transactions on BSC. It is not a mandatory rule for the entire network—instead, it allows each validator and node operator to voluntarily adopt it based on their capabilities and requirements.

The main goal of this proposal is to address the issue of heavy gas consumption that can slow down block production. After implementing a configurable transaction threshold, large transactions that previously caused reorganizations become more reliable. This helps validators perform their duties normally even during longer processing times, while reducing delays in transaction validation.

Network Performance: Data Supporting the Need

By the end of September 2025, the BNB Chain had reached 58 million monthly active wallet addresses— a number surpassing other well-known networks like Solana. This significant growth directly demonstrates why a more robust and reliable infrastructure is needed to maintain the stability of the entire ecosystem.

The current average transaction fee on BSC is only around $0.05 to $0.20, significantly lower than Ethereum’s $0.44. This cost advantage is one of the main reasons for increasing adoption, so BNB Chain must ensure its infrastructure can support the ongoing rise in activity.

The Flexible Approach: Why BNB Chain Differs from Ethereum

Unlike Ethereum, which implemented rigid protocol-level rules through EIP-7825, BNB Chain has chosen a more flexible approach. BEP-640 allows each validator to decide based on their own situation—those with high-performance infrastructure can set higher limits, while those prioritizing stability can use stricter caps.

This strategy reflects BNB Chain’s commitment to providing options rather than mandatory changes. It enables the network to grow organically while maintaining control for each participant.

Timing: Fermi Hard Fork and a New Era of Performance

BEP-640 will arrive just before the Fermi Hard Fork of BNB Chain on January 14, 2026. This upgrade will bring faster block times and improved EVM performance, collectively strengthening the stability and efficiency of the entire network.

The combination of BEP-640 and the Fermi Hard Fork represents a comprehensive effort to upgrade the foundation of BNB Chain for the future.

The Bigger Picture: DeFi, Gaming, and Next Steps

Total Value Locked in the BNB ecosystem now stands at an impressive $17.1 billion, with much of it concentrated in platforms like PancakeSwap. This ecosystem continues to innovate in DeFi, Gaming, AI, and more. To maintain momentum, BNB needs to keep strengthening its infrastructure while delivering faster and more stable experiences.

BEP-640 is just one of a series of upgrades positioning BNB Chain as one of the leading Layer 1 networks—not only fast but also reliable and stable.

Conclusion: Stability with Flexibility

BEP-640 is a practical solution to a complex problem—how to keep the network stable as it grows. By offering voluntary adoption and flexible configuration, BNB Chain provides a model that balances innovation and stability. The success of this proposal will be reflected in the actual adoption rate among validators and in the network performance metrics in the coming months.
