Pull Request Overview

Adds comprehensive validation checks within isKnownCanonicalBlock to guard against mismatched block metadata and logs warnings on failure.

• Introduces a deferred warning log for any validation error
• Adds explicit comparisons for parent hash, transactions, anchor tx, uncle hash, coinbase, difficulty, mix digest, block number, gas limit, timestamp, extra data, base fee, and withdrawals
• Returns detailed error messages on the first detected mismatch

• You’ve added checks for an empty transaction list and other mismatches. It would be good to add unit tests that simulate each failure case to ensure these new branches are covered.
