Investigate and Resolve Possible Ethereum-Related Equivocation in Collator Node

[asiniscalchi]

As a blockchain infrastructure engineer, I want to investigate and resolve the possible Ethereum-related equivocation error in the collator node, so that Ethereum block data is handled accurately and the network's integrity is preserved.

Description

The collator node detects possible equivocations while processing Ethereum block.
This discrepancy in Ethereum block processing needs to be thoroughly investigated and resolved to maintain accurate parachain operations and prevent potential network issues.

These is possibly related work:

Notes

• The error is specific to the Ethereum block processing pipeline within the collator node.
• Resolving this issue is critical to maintaining seamless Ethereum-parachain integration and network stability.
