Polygon network conducts emergency Hard Fork to fix Node synchronization bug.
The Polygon Foundation has officially reported a consensus failure that occurred on the Ethereum Layer 2 network.
What happened?
Bugs in the Bor node and Erigon node interfered with the RPC (Remote Procedure Call) service, disrupting communication between the application and the blockchain. Although the network itself was operational, there was a delay in finality of 10 to 15 minutes. Malicious proposals from validators caused the Bor node to split into multiple forks, halting block generation.
Countermeasure
According to Polygon co-founder Sandeep Nailwal, the following update is being distributed urgently:
After the update, the full operation of the node was confirmed, and the checkpoint milestone function has been normalized.
Background
In July, the Heimdall V2 mainnet was offline for about 1 hour. At that time, it was due to a consensus bug, but slight synchronization issues occurred with multiple RPC providers. The Polygon side has established a continuous monitoring system and is committed to ensuring future stability.
