def run_recover(b):
    pre_commit = query.get_pre_commit_state(b.connection, PRE_COMMIT_ID)

    # Initially the pre-commit collection would be empty
    if pre_commit:

        # NOTE: the pre-commit state can only be ahead of the commited state
        # by 1 block
        if latest_block and (latest_block['height'] < pre_commit['height']):
            query.delete_transactions(b.connection, pre_commit['transactions'])
