Is it possible to broadcast a transaction to the network without revealing my personal IP address? My first guess is to connect bitcoind over Tor with proxy=127.0.0.1:9050. Is it the good way to do it or do I have other options?

Thanks.

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. en.bitcoin.it/wiki/Fallback_Nodes Can anyone who use bitcoind over Tor guide me on how to do it right? – dunand Feb 20 at 20:40
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♦ Feb 21 at 8:00

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.
