[Application Options] ; ------------------------------------------------------------------------------ ; Data settings ; ------------------------------------------------------------------------------ ; The directory to store data such as the block chain and peer addresses. The ; block chain takes several GB, so this location must have a lot of free space. ; The default is ~/.btcd/data on POSIX OSes, $LOCALAPPDATA/Btcd/data on Windows, ; ~/Library/Application Support/Btcd/data on Mac OS, and $home/btcd/data on ; Plan9. Environment variables are expanded so they may be used. NOTE: Windows ; environment variables are typically %VARIABLE%, but they must be accessed with ; $VARIABLE here.

NOTE: Specifying a proxy will disable listening ; for incoming connections unless listen addresses are provided via the 'listen' ; option. ; proxy=127.0.0.1:9050 ; proxyuser= ; proxypass= ; The SOCKS5 proxy above is assumed to be Tor (https://www.torproject.org). ; If the proxy is not tor the following may be used to prevent using tor ; specific SOCKS queries to lookup addresses (this increases anonymity when tor ; is used by preventing your IP being leaked via DNS). ; noonion=1 ; Use an alternative proxy to connect to .onion addresses. The proxy is assumed ; to be a Tor node. Non .onion addresses will be contacted with the main proxy ; or without a proxy if none is set. ; onion=127.0.0.1:9051 ; onionuser= ; onionpass= ; Enable Tor stream isolation by randomizing proxy user credentials resulting in ; Tor creating a new circuit for each connection. This makes it more difficult ; to correlate connections. ; torisolation=1 ; Use Universal Plug and Play (UPnP) to automatically open the listen port ; and obtain the external IP address from supported devices. NOTE: This option ; will have no effect if exernal IP addresses are specified. ; upnp=1 ; Specify the external IP addresses your node is listening on. One address per ; line. btcd will not contact 3rd-party sites to obtain external ip addresses. ; This means if you are behind NAT, your node will not be able to advertise a ; reachable address unless you specify it here or enable the 'upnp' option (and ; have a supported device). ; externalip=1.2.3.4 ; externalip=2002::1234 ; ****************************************************************************** ; Summary of 'addpeer' versus 'connect'. ; ; Only one of the following two options, 'addpeer' and 'connect', may be ; specified. Both allow you to specify peers that you want to stay connected ; with, but the behavior is slightly different. By default, btcd will query DNS ; to find peers to connect to, so unless you have a specific reason such as ; those described below, you probably won't need to modify anything here. ; ; 'addpeer' does not prevent connections to other peers discovered from ; the peers you are connected to and also lets the remote peers know you are ; available so they can notify other peers they can to connect to you. This ; option might be useful if you are having problems finding a node for some ; reason (perhaps due to a firewall). ; ; 'connect', on the other hand, will ONLY connect to the specified peers and ; no others. It also disables listening (unless you explicitly set listen ; addresses via the 'listen' option) and DNS seeding, so you will not be ; advertised as an available peer to the peers you connect to and won't accept ; connections from any other peers. So, the 'connect' option effectively allows ; you to only connect to "trusted" peers. ; ****************************************************************************** ; Add persistent peers to connect to as desired.
