Re: Re[2]: [rishab@dxm.org: Re: [silk] inside the Great FireWall...]

i think the answer is, don't distribute the top tier addresses at all.
distribute a collection of randomised node ip's amongst a very large
number of widely distributed nodes, not even tor nodes, to avoid the
port blocking problem, get people to run a small webserver application
for this, which fetches a random set of nodes from the network via a a
tor client/server running on the same system. a lot of these nodes will
be running on dynamic ip's which will make the process of blocking them
harder still.

idk, just throwing in some more ideas. it's pretty obvious that tor
needs to get just that little bit more distributed and less centralised
somehow. the use of dynamic ip addresses, and directory services which
only dispense a small amount of the directory from a web server port.

probably the model which gnutella 2 runs on is a good way to do it... in
the end, it may well be neccessary for clients to actually do port scans
of random ip addresses to find connected nodes and once one is found the
joining of the network is not gonna be slow. and hiding it all in a
common port might be a very good idea, for example, 53, or 21 or 22 or
25 or 80 or 443. once a client joins the network it can cache all the
nodes it gets for circuits. decentralising the database by making it so
nodes only know their neigbours would also be a good thing, requesting
circuits would just be a matter of propagating a request for a circuit
to an internet zone, and it propagates outwards until it hits the zone
and back comes the circuit.
