BNB Chain Releases BSC-Reth Hotfix v0.1.4
Node operators on BNB Smart Chain are told to install the mandatory upgrade ahead of the scheduled Jenner hardfork.
Updated on Nov. 6, 2026 in Software
BNB Chain released BSC-Reth v0.1.4 on November 3, 2026, describing it as a mandatory upgrade for BSC mainnet node operators. The hotfix is aligned with the corresponding BSC v1.8.2 client release.
Why it matters
Nodes running outdated software at hardfork activation risk following the old rules and falling out of sync with the network. BNB Chain also wants all existing validators moved to a Reth-based client by the end of 2026.
BNB Chain cites roughly a 40% throughput increase over previous configurations for the Reth-based client, which is aligned with BSC v1.8.2. The release notes do not quantify how many validators have adopted the update so far.
The players
BNB Chain
BNB Chain is the blockchain network behind BNB Smart Chain, which operates the BSC network that node operators run this client on.
The details
Node operators install the hotfix and then restart the node, and BSC-Reth supports both historical sync and live sync. BNB Chain confirmed opBNB is not affected and said no immediate action is required from users or developers beyond node operators preparing for the upgrade.
Timeline
November 3, 2026: BSC-Reth v0.1.4 hotfix released.
November 6, 2026: BNB Chain publicly acknowledged a potential security risk affecting the Reth client.
December 8, 2026, 02:30 UTC: Jenner hardfork scheduled to activate.
End of 2026: Target date for all validators to be moved to a Reth-based client.
The Tech Race
BNB Chain's push to move all validators onto the Reth client by the end of 2026 follows the broader migration of EVM networks toward Reth as an alternative to older execution clients. The shift positions BSC's validator infrastructure alongside other chains adopting the same client in their upgrade roadmaps.
Node operators must install the v0.1.4 hotfix and restart their nodes to avoid falling behind the network at the Jenner hardfork. Users and developers do not need to take immediate action according to BNB Chain.
The takeaway
Node operators running BSC should install BSC-Reth v0.1.4 and confirm their node is current before the Jenner hardfork activates on December 8, 2026. Planning the move to a Reth-based client now will avoid a rushed migration ahead of the end-of-2026 target.
What happens next
The Jenner hardfork is scheduled to activate on December 8, 2026, at 02:30 UTC, and validators are expected to be fully ready before then.
