Description

It's been great seeing all the progress in standardizing various aspects of libp2p in the past few months. Great work.

I just want to bring up implementing onion routing over libp2p. Past work has focused mainly on adding Tor onion routing as a libp2p transport (see here). However, Tor is just one way to do onion routing. Recent work by @gpestana has focused on other onion routing protocols like HORNET. Even though every onion routing protocol has its quirks, it would be great to start standardizing onion routing over libp2p.

Research direction

Start by reviewing the linked go-onion-transport work and the HORNET paper, then compare how Tor and other onion-routing protocols could fit over libp2p. The issue does not name a file, test, or entry point; done would require an agreed standard for onion routing over libp2p.
