We're trying to measure the traffic capacity of the Tor Network, particularly as it relates to hidden services.[0]

But we don't know how long the average hidden service rendezvous path is:

  • Either side can have a 3 or 4 hop connection, due to cannibalization
  • Clients can use Tor2Web and have one-hop paths
  • Servers can or will be able to use (Rendezvous) Single Onion Services, and have one hop paths

We know it's probably somewhere between 7 and 9 connections / hops, but that's a large range. And it may shrink as more (R)SOS servers come online.

Is there a privacy-preserving way of collecting these statistics?
(We'd need to combine stats from clients and hidden services.)

Is it worth doing this as a once-off, or should we (re)design the collection of a number of privacy-preserving stats?

Finally admitting that 0.3.??? was a euphemism for Tor: unspecified all along.

at least no longer valid for Tor2Web, since Tor2Web was removed with fire :-(
