[Mnet-devel] RE: [p2p-hackers] Freenet, Mnet, GNUnet, Circle

[Greg Bildson]

We spent a year dealing with those "spammy client" issues on Gnutella.  Most
of the offenders ended  up dying an early death after we devised both
specific and general mechanisms for dealing with offenders.  Having a
rapidly evolving protocol helps to some extent.

Thanks

I am not sure what flaws he is referring to, but our biggest problem
right now is due to more requests being pumped into the network than the
network can handle, which I suspect would be a problem for almost any
network irrespective of its routing algorithm.

We have a pretty new and IMHO innovative solution to this problem called
"rate limiting", but we are still tinkering with it to get it right.  We
may have just fixed a serious bug in this so the next few days will be
instructive.  If it works I will probably be doing at talk on it at
DEFCON next month.

Either way, I think the problems Freenet is facing right now are
actually problems that would be faced by any data insertion and
retrieval P2P network when people start to develop third-party clients
that pump requests into the network in an aggressive manner.  Hopefully
others will be able to benefit from the lessons we are learning should
they run into similar problems (as I suspect many will).

Ian.
