BNB Chain has asked node operators to complete the required software update before the Osaka/Mendel hard fork hits the mainnet on April 28.
summary
- BNB Chain has required node operators to install BSC v1.7.2 before launching the Osaka/Mendel hard fork.
- The mainnet upgrade on April 28 comes after the testnet activation and adds stability, gas limits, and finality.
- BNB Chain said that outdated settings and bad binary replacement could cause nodes to lose sync.
The network said operators should move to BSC v1.7.2 and remove outdated settings to keep nodes operating normally.
BNB Chain developers said that node operators must complete to update Before the Osaka/Mendel hard split was published on the BSC mainnet. The network has scheduled the upgrade for April 28 at 2:30 AM UTC.
The notice stated that operators need to replace binaries properly and clean up old configuration fields. The team said these steps are necessary to prevent nodes from “losing sync” during the upgrade.
The message focuses on infrastructure readiness before the hard fork date. It also appears that the update is not optional for operators who want their nodes to remain compatible with the chain.
The deadline comes as BNB Chain transitions from testnet setup to full mainnet deployment. This shift usually pays more attention to the performance of the validator and node across the network.
The Mendel upgrade adds BEP-652, which brings EIP-7825 to the BNB chain through a protocol-level gas cap for each transaction. The maximum is set to 16,777,216 gas.
This change means that all nodes will reject transactions that exceed the limit in the same way. BNP Series He said this method is more reliable than the previous soft-cover model that operators can handle differently.
The broader network upgrade includes nine Best Environmental Practices (BEPs) in total. BNB Chain also said it has approved seven of the thirteen associated Ethereum proposals faceincluding six that require a hard fork and one client-side RPC change.
The network did not adopt the other six proposals due to structural differences. It also added two updates to the BNB chain with BEP-657 and BEP-648.
Testnet was rolled out before the mainnet was launched
The BNB chain activated Osaka/Mendel Solid fork On the BSC testnet on March 24 at block 88,379,325. The testing phase improved block building, large-scale transaction processing, network stability, and execution accuracy, developers said.
BEP-657 determines when large binary transactions can be included based on the block number. BEP-648 aims to reduce latency and speed up backhaul on the network.
Mainnet rollout now depends on operators completing the required upgrade on time. The latest alert shows that BNB Chain wants nodes to be fully operational before the hard fork begins on April 28.
