If you know any funders outside the US who care about privacy, anonymity,
or circumvention, we're all ears. :)

I am certain there are funders outside the US but whilst Tor remains a tool the US I would guess they'd be reticent to contribute and who could blame them.

Add to this the number of Tor nodes run from US institutions (many at US gov funded edu's) and you should be able to see who that "Global Adversary" is!

****  US - GOV ****

Conspiracy theories aside, this is an important open research question
that still needs more research attention: if you can watch a given amount
of Internet backbone traffic, how much of the Tor network can you surveil?

Here are three papers to get you started if you want to learn more about
this issue:

Designs like Tor have always accepted that they will be vulnerable to
a global passive adversary:

I think you'll find that Tor only became officially incapable of protecting from such an adversary around 2004/5 when numerous request to add this protection to Tor was made. Since then its been the official policy not to protect from such a threat (so as to head off any complaints it does not do the job perhaps ??).

It a good idea that you speak for Tor only, not other system here, where there are/have been genuine attempts to provide full anonymity, no get out clause.

>The key point to realize here is that you shouldn't so much think about
the locations of the Tor relays, but instead think about which networks
the communication between Tor users and the Tor network traverses,
and which networks the communication between the Tor network and the
destination services (e.g. websites) traverses. The Internet itself has
bottlenecks that make our task hard even if we could engineer a good
diversity of relay locations.

Conspiracy theorist slander aside, FACT: in the mid-1990's IBM had 80% of the Global Internet Traffic flowiing through their servers, paid for by US military contracts, all routed through the US, so the US -GOV could spy on the global internet traffic.

>We can certainly imagine that some pieces of the US government have the
capability to tap large pieces of the Internet:

But what saves us here is that the US government, like all governments,
is not one person. It's a lot of different groups, all with different
goals and different capabilities.

That saves you??

Are you saying its not co-ordinated? Did you once work for US - Gov - Mil research?

>So a) that means some parts of the
government actually want to support freedom of speech and/or need for
themselves the security properties that Tor provides, and b) there's a
huge amount of bureaucracy to slow down coordination between different
pieces of the government -- so even if somebody at NSA can beat Tor,
that doesn't mean somebody at FBI can call him up and ask for answers.
