- Add propose_only_if_mempool_not_empty config option (default: True) to skip block proposals when mempool is empty - Add detailed logging for transaction processing in block proposals (sender/recipient validation, balance checks, duplicate detection) - Check for existing transactions in database before adding to prevent duplicates - Improve genesis block creation: check by height and hash, use "genesis" as proposer to avoid hash conflicts - Add proper error handling and rollback for
