Tor does at a routing level, the user loses. I know Tor cannot defeat the
global passive adversary, but it seems Tor cannot even protect against a
local passive adversary. The Steven Murdoch paper on IX sampling should
scare everyone the most.

It is a hard and open research problem. I think it's likely that at least
a partial solution exists. As Nick said, our latest work is somewhat
relevant. Expanding from trust of individual parts of the network to
expectations about the likelihood that they are cooperating is still in
the early stages, however.
