With the Osaka/Mendel hard split looming, scheduled for April 28, this is a major event in one of the… BNB Chain Latest web development initiatives.
Now, users will find themselves encouraged to stake their investments and prepare for the transformation towards sub-second block times.
The network has been aggressively pushing the performance limits over the past year, with blocking times reduced from 1.5 seconds (under Lorentz) to just ~0.45 at Fermi. However, while this rapid acceleration has made BNB Chain one of the fastest blockchain networks, it has also created issues with implementation consistency and reliability.
At this stage, Instead of increasing speed further, Osaka/Mendel is working to improve performance at this level, ensuring that the network operates smoothly, predictably and is up to supporting large-scale, enterprise-level applications.
Nine BEPs have been announced that offer faster finality and predictable gas behavior
The Osaka/Mendel upgrade introduces nine Binance Evolution Proposals (BEPs), which help improve transaction execution and network stability.
Completing the transaction faster is definitely a huge improvement. Block production times are already very fast, but with this finality (the point at which transactions become irrevocable), uncertainty is reduced for users and developers participating in the network.
Gas predictability is equally important. Transaction fees can be very dynamic and difficult to predict especially during times of peak network usage. One of the things this new upgrade has brought is that gas costs are now more consistent and predictable in heavy traffic situations.
This shift represents a conscious departure from prioritizing raw speed over everything else, focusing instead on consistency, reliability, and user experience, three components required for widespread adoption.
Gas limit and execution control were introduced in the Mendel upgrade
One of the specific technical components of the upgrade is the introduction of a transaction gas cap on the network via EIP-7825 through BEP-652.
By providing clearer limits on how much computational workload a single transaction is allowed to consume, this change dramatically increases the predictability of block construction. This allows for reduced gas processing at the transaction level, which can lead to inefficient and unpredictable performance on the network by trying to enforce these limits.
For developers, this means that they can deal with a less marginal situation when creating applications, for example, those who trade and hold their assets; And for the users themselves, more consistent results in terms of transaction outcomes.
Handling heavyweight transactions more efficiently also prevents situations where personal transactions hinder global performance.
Enhanced encryption support expands enterprise access
Another important addition in the Osaka/Mendel hard fork is better support for secp256r1, a commonly used encryption standard that is widely adopted in traditional hardware security systems.
This makes it easy to integrate with existing security infrastructure, such as enterprise-grade hardware modules and authentication systems that may exist outside the traditional native crypto space.
Thus, BNB Chain has expanded access to institutions that rely on already existing security frameworks through its support for the crypto standard. This shift reflects a broader trend in the industry, where more and more blockchain networks act like traditional systems to support adoption.
This upgrade provides a bridge between decentralized infrastructure and traditional security practices, simplifying the deployment and integration of enterprise blockchain solutions.
Upgrading a conservative node indicates a major shift in the network
In addition to the protocol updates, BNB Chain has introduced its new blockchain, BSC v1. 7.2, An update is required for all major network node operators. Note: Participants need to update their contract by April 28, 02:30 AM UTC or you will be kicked from the network.
The upgrade process itself leaves little room for complexity, as it is really just a binary replacement. However, the presence of the JournalFileEnabled field in driver configuration files should be prevented because it may prevent the current protocol behavior from working correctly.
These prerequisites highlight the importance of the Osaka/Mendel fork. In contrast to optional updates, this is a coordinated, network-wide upgrade that inherently requires full participation to maintain consensus and compatibility.
This type of upgrade is important because it means that all nodes operate under the same set of rules which prevents a fragmented network and helps maintain its overall health.
Choose the right strategy
The BNB Chain upgrade roadmap in 2026 is a clear record of its changing priorities. Therefore, previous upgrades mainly revolved around reducing block time.
Enter Osaka/Mendel, where the shift to execution quality is absolutely unmistakable. Instead of worrying about getting average lag and jitter to an all-time high, the network tries to approximate it because it’s already very fast.
This consists of strengthening gas mechanisms, forced execution limits, and consistent binary transaction processing in case of deviation.
This brings a level of verification and predictability to users and developers alike. This approach allows applications to be more confident in the execution results, while, on the other hand, users experience less disruption even with high demand over time.
A new approach to long-term network reliability
The Osaka/Mendel hard fork represents a much larger strategic shift for the BNB chain, moving away from the previous focus on unfettered throughput towards embracing institutional-level reliability.
As adoption of blockchain technology extends from simple retail users to enterprise tools and large-scale use cases, the need for speed must now play second fiddle to consistency and predictability. It is crucial that networks are not only scalable in terms of transaction speed, but also in ensuring that those transactions are processed reliably, whatever the circumstances.
BNB Chain looks to address these vulnerabilities in order to enable the next set of applications that require performance and stability.
Moving to the next stage of blockchain evolution will require significant upgrades, and this upcoming mainnet upgrade is its first critical milestone.
