Is there added security by stacking hidden services? So a.onion is just a reverse proxy for b.onion? Buys you a bit more time before the final server gets popped? Or can you increase the number of Tor hops for your hidden service to get a similar effect?<p>Thinking of Silk Road - was it ever proved they leaked their IP versus some more advanced way of finding the server? (I know, it&#x27;s highly likely that such a poorly written system would have had a real IP leak, just wondering what documented facts we have.)
