@ -73,7 +73,7 @@ Options:
--address URL Equivalent to --listen-address URL --public-address URL.
--peers NUM Try to manintain that many peers [default: 25].
--no-discovery Disable new peer discovery.
--upnp Use UPnP to try to figure out the correct network settings.
--no-upnp Disable trying to figure out the correct public adderss over UPnP.
--node-key KEY Specify node secret key, either as 64-character hex string or input to SHA3 operation.
--cache-pref-size BYTES Specify the prefered size of the blockchain cache in bytes [default: 16384].
