How to broadcast a transaction anonymously

Answers

Here is the solution I found to broadcast transaction on the bitcoin network without revealing your IP: connect bitcoind over the Tor network. Here is my guide.

Edit your torrc file to add .onion bitcoin nodes:

mapaddress 192.0.2.2 ijzt2eeizty3p5xe.onion
mapaddress 192.0.2.3 j43z65b6r2usg3vk.onion
mapaddress 192.0.2.4 pvuif6nonbhj3o3r.onion

Start Tor

Edit .bitcoin/bitcoin.conf to connect bitcoind over the Tor network. Add:

proxy=127.0.0.1:9050
connect=192.0.2.2
connect=192.0.2.3
connect=192.0.2.4

When Tor is started (green onion) you can launch bitcoind.

If I want to connect over Tor the client will not be able to discover new peers by itself. Should I use a list of peers with .onion addresses. I saw some info here. https://en.bitcoin.it/wiki/Fallback_Nodes Can anyone who use bitcoind over Tor guide me on how to do it right?

Someone needs to set up a web server that accepts bitcoin transactions for submission. Then you could just use Tor to submit the transaction by HTTP. – David Schwartz – 2012-02-21T08:00:19.367
