                           guarantees we don't relay invalid transactions, but
                           means we relay nothing if not mining);

                           block due to transaction volume [default: 6283184].
  --extra-data STRING      Specify a custom extra-data for authored blocks, no
                           more than 32 characters.

  --pruning METHOD         Configure pruning of the state/storage trie. METHOD
                           may be one of auto, archive, fast:
