BNB Chain developers have set the Lorentz hard fork for mainnet block height 42,100,000, giving validators and node operators a fixed point for the network upgrade to take effect.

The update includes BEP-341 transaction priority changes that are intended to lower gas costs by 20%. For the rollout to proceed smoothly, network operators need to update their software before the chain reaches the trigger block.

Mainnet activation plan is now set

The Lorentz upgrade is being introduced as a scheduled hard fork, meaning it will change the network rules at a specific block height rather than at a general time window. In this case, BNB Chain has tied activation to block 42,100,000 on mainnet.

A block-height trigger gives developers, validators, and infrastructure providers a clear coordination target. It also provides users and applications with a timeline for when the new rules are expected to begin applying on the live network.

BEP-341 focuses on transaction priority and fees

At the center of the upgrade is BEP-341, which changes how transaction priority is handled on BNB Chain. According to the announced scope of the hard fork, the goal is to reduce gas costs by 20% for network users.

That figure should be understood as the target of the upgrade rather than a guarantee that every transaction will become cheaper by the same amount. Actual costs can still vary depending on network conditions, the design of an application, and the type of transaction being submitted.

Why operator coordination matters

Hard forks are routine in blockchain networks, but they still require careful execution. Because a hard fork changes consensus rules, validators and node operators must install the relevant software update before activation if the network is to move forward cleanly.

If enough operators are not prepared by the trigger height, a chain can face disruption, inconsistent behavior across nodes, or degraded performance. That is why the Lorentz rollout is not only a software release but also a coordination event for the people running core network infrastructure.

A practical upgrade with competitive relevance

The announced changes point to continued tuning of BNB Chain’s mainnet infrastructure. Lower fees and improved transaction handling can be especially important on a network used for trading, gaming, payments, DeFi, and other activity where transaction costs are often a deciding factor.

BNB Chain has long competed on accessibility, including relatively low fees and fast settlement. In that context, fee-related upgrades can matter operationally, even if they do not by themselves signal immediate changes in usage or market activity.

What comes next

The next confirmed step is for validators and node operators to complete their software upgrades before mainnet reaches block 42,100,000. If that preparation is completed in time, the Lorentz hard fork can activate under the announced schedule.

After activation, the practical test will be whether the BEP-341 changes deliver the expected transaction-handling improvements and whether users see the reported gas-cost benefits in real network conditions.
