Re: [tor-talk] Directory Server Decentralization
Hi,
(trimmed)
me replying as non-tor-people, non-dev, non-crypto-expert, non-researcher.

If you talk about DHT (distributed hash tables) to bootstrap rather than
fetching the consensus from a central place or a mirror... I remember
that it wasn't safe enough back at that time. I don't know if anyone is
working on it.

If that's for the relay list, probably not so useful. Censors could
still put them back together. Every client has to know about the
network. All an attacker would have to do is run a client and block
every IP:PORT it finds in the consensus.
And the list of relays is available. Projects of the Tor Project show
currently running relays.
If that's for unlisted relays aka bridges, it exists to some degree. The
pool of bridges is split and different addresses are given out via
email, website and manually.

If I'm not mistaking Torservers.net operates bridges that don't publish
themselves to the BridgeDB.

The are bundles containing obfsproxy and flash proxy to work around
blockades.
It separates the user base. It is also a malware problem. I haven't seen
such bundle, but they seem to exist. People seem to find it a good idea
to repack the bundle with some nasty stuff. Therefore users have to
trust those creating these "spins".

Please have a look at flash proxy [1], it goes in that direction with
ticket 7944 [2]

Thank you for your time as well. Thank you for thinking about how to
improve/change things.
