* Add block categorization (is_final=) * Add godo task for vulcanizeDB (Example of how everything could work together) * Add unique constraint on block_number and node * Add index on block_id for transactions_table * Add node_id index on blocks table * Sort transactions returned from FindBlock by tx_hash * lowercase tx_to, tx_from like etherscan
