Polygon May Experience Temporary Consensus Finality Delay Due to Bor and Erigon Bug Affecting RPC and Validator Syncing

• Root cause: a Bor and Erigon node bug triggered validator and RPC resyncs

• Impact: RPC service disruptions and validator syncing delays; core chain remained live

• Mitigation: node restarts resolved issues for many participants; engineering teams continue debugging

Polygon consensus finality delay: Bor and Erigon bug forced RPC and validator resyncs; learn current status and recovery steps. Read updates from COINOTAG now.

What caused the Polygon consensus finality delay?

Polygon consensus finality delay was caused by a bug affecting Bor and Erigon node configurations that prevented node progress for some participants, forcing RPC providers and validators to rewind to the last finalized block and resynchronize while the chain continued producing blocks.

How did the bug affect RPC services and validators?

The bug impacted Remote Procedure Call (RPC) services and validator syncing, resulting in access issues for some apps built on Polygon. Affected validators and RPC providers rewound to the previously finalized block, resynced, and, in many cases, resolved the issue after restarting the affected nodes.

Polygon faced a temporary consensus finality delay on Wednesday caused by a Bor and Erigon bug that impacted RPC services and validator syncing.

Polygon reported a temporary delay in consensus finality early Wednesday due to a software issue in Bor and Erigon node implementations. The incident disrupted certain RPC endpoints and caused some validators to revert to the last finalized block and re-sync.

The Polygon blockchain continued producing blocks during the incident. However, some RPC providers and validators encountered progress stalls that required node restarts or full resynchronization. Polygon’s engineering teams coordinated with infrastructure providers to expedite debugging and restore full functionality.

When was the problem detected and what is the current status?

The issue began early on Wednesday and was documented on Polygon’s status page. Engineers have identified the bug as blocking node progress in specific configurations; many participants restored service after restarting nodes while full debugging and fixes are ongoing.

What should node operators and RPC providers do to mitigate the issue?

Node operators and RPC providers experiencing stalls should:

1. Check node logs for progress or synchronization errors.
2. Restart impacted Bor and Erigon nodes as a first step.
3. If restarts fail, rewind to the last finalized block and initiate a controlled resync.
4. Coordinate with infrastructure and validator peers for rollback and consensus safety.

Frequently Asked Questions

How long did the Polygon finality delay last?

The incident began early Wednesday and initial recoveries were observed later the same day after node restarts. Full debugging and confirmation of fixes continued with engineers and infrastructure partners coordinating to ensure stability.

Is user funds or chain security affected?

There is no indication that user funds or core chain security were compromised. The chain remained live and continued to produce blocks; the issue affected node progress and RPC availability for some participants.

Key Takeaways

• Root cause: Bor and Erigon node bug blocked progress for certain configurations.
• Impact: RPC disruptions and validator resyncs, while block production continued.
• Mitigation: Node restarts resolved the problem for many; coordinated debugging is ongoing.

Conclusion

Polygon’s consensus finality delay was driven by a Bor and Erigon node bug that disrupted RPC services and forced resynchronization for some validators. The network continued producing blocks and many participants restored service after restarting nodes. COINOTAG will monitor updates and provide follow-up coverage as engineers confirm permanent fixes and further guidance.
