TOR SUPPORT IN BITCOIN |
||||
====================== |
||||
|
||||
It is possible to run Bitcoin as a Tor hidden service, and connect to such services. |
||||
|
||||
The following directions assume you have a Tor proxy running on port 9050. Many distributions |
||||
default to having a SOCKS proxy listening on port 9050, but others may not. |
||||
In particular, the Tor Browser Bundle defaults to listening on a random port. See |
||||
https://www.torproject.org/docs/faq.html.en#TBBSocksPort for how to properly |
||||
configure Tor. |
||||
|
||||
|
||||
1. Run bitcoin behind a Tor proxy |
||||
--------------------------------- |
||||
|
||||
The first step is running Bitcoin behind a Tor proxy. This will already make all |
||||
outgoing connections be anonimized, but more is possible. |
||||
|
||||
-socks=5 SOCKS5 supports connecting-to-hostname, which can be used instead |
||||
of doing a (leaking) local DNS lookup. SOCKS5 is the default, |
||||
but SOCKS4 does not support this. (SOCKS4a does, but isn't |
||||
implemented). |
||||
|
||||
-proxy=ip:port Set the proxy server. If SOCKS5 is selected (default), this proxy |
||||
server will be used to try to reach .onion addresses as well. |
||||
|
||||
-tor=ip:port Set the proxy server to use for tor hidden services. You do not |
||||
need to set this if it's the same as -proxy. You can use -notor |
||||
to explicitly disable access to hidden service. |
||||
|
||||
-listen When using -proxy, listening is disabled by default. If you want |
||||
to run a hidden service (see next section), you'll need to enable |
||||
it explicitly. |
||||
|
||||
-connect=X When behind a Tor proxy, you can specify .onion addresses instead |
||||
-addnode=X of IP addresses or hostnames in these parameters. It requires |
||||
-seednode=X SOCKS5. In Tor mode, such addresses can also be exchanged with |
||||
other P2P nodes. |
||||
|
||||
In a typical situation, this suffices to run behind a Tor proxy: |
||||
|
||||
./bitcoin -proxy=127.0.0.1:9050 |
||||
|
||||
|
||||
2. Run a bitcoin hidden server |
||||
------------------------------ |
||||
|
||||
If you configure your Tor system accordingly, it is possible to make your node also |
||||
reachable from the Tor network. Add these lines to your /etc/tor/torrc (or equivalent |
||||
config file): |
||||
|
||||
HiddenServiceDir /var/lib/tor/bitcoin-service/ |
||||
HiddenServicePort 8333 127.0.0.1:8333 |
||||
|
||||
The directory can be different of course, but (both) port numbers should be equal to |
||||
your bitcoind's P2P listen port (8333 by default). |
||||
|
||||
-externalip=X You can tell bitcoin about its publicly reachable address using |
||||
this option, and this can be a .onion address. Given the above |
||||
configuration, you can find your onion address in |
||||
/var/lib/tor/bitcoin-service/hostname. Onion addresses are given |
||||
preference for your node to advertize itself with, for connections |
||||
coming from unroutable addresses (such as 127.0.0.1, where the |
||||
Tor proxy typically runs). |
||||
|
||||
-listen You'll need to enable listening for incoming connections, as this |
||||
is off by default behind a proxy. |
||||
|
||||
-discover When -externalip is specified, no attempt is made to discover local |
||||
IPv4 or IPv6 addresses. If you want to run a dual stack, reachable |
||||
from both Tor and IPv4 (or IPv6), you'll need to either pass your |
||||
other addresses using -externalip, or explicitly enable -discover. |
||||
Note that both addresses of a dual-stack system may be easily |
||||
linkable using traffic analysis. |
||||
|
||||
In a typical situation, where you're only reachable via Tor, this should suffice: |
||||
|
||||
./bitcoind -proxy=127.0.0.1:9050 -externalip=57qr3yd1nyntf5k.onion -listen |
||||
|
||||
(obviously, replace the Onion address with your own). If you don't care too much |
||||
about hiding your node, and want to be reachable on IPv4 as well, additionally |
||||
specify: |
||||
|
||||
./bitcoind ... -discover |
||||
|
||||
and open port 8333 on your firewall (or use -upnp). |
||||
|
||||
If you only want to use Tor to reach onion addresses, but not use it as a proxy |
||||
for normal IPv4/IPv6 communication, use: |
||||
|
||||
./bitcoin -tor=127.0.0.1:9050 -externalip=57qr3yd1nyntf5k.onion -discover |
