  +-----------------------

  +- BIP 61 reject messages are now deprecated. Reject messages have no use
  + case on the P2P network and are only logged for debugging by most network
  + nodes. Furthermore, they increase bandwidth and can be harmful for privacy
  + and security. It has been possible to disable BIP 61 messages since v0.17
  + with the `-enablebip61=0` option. BIP 61 messages will be disabled by default
  + in a future version, before being removed entirely.
