Re: Hacker strikes through student's router

i really like that idea. there's plenty of specifications around the place about how to set up secure electronic cash systems based on asymmetric cryptography. if tor were to integrate it into its infrastructure, this would mitigate the cost side of the node running business, and it would definitely increase the implementation of tor nodes. if your packets have tor-cash attached to them, they are put in the top bucket, if they are not, they go in the low priority bucket. people will learn pretty fast.

or how about don't bother with the electronic cash thing, make a protocol which signifies that the packet originated from a tor server and have these packets prioritised. then the p2p folks will be more likely to set up nodes (being that they mostly have bulk bandwidth, they are a good target) will set up more nodes because of the advantage of the bandwidth being more available to them if they run a node.

What if we had a Tor network where exit node operators made Tor-money,
and Tor-money was necessary to use the network? Or perhaps, Tor-money
at least gave you priority in using the network, so all those P2P
traders wouldn't slow you down so much? Maybe exit node operators
could even sell their Tor-money for real cash, to potential Tor users.

People tend to have two contradictory views about proposals like this.
One is that such a Tor network would never work, because people would
prefer to use the free one. The other is that free Tor networks will
never work, because no one will take the heat to run an exit node.

The point is that this proposal cuts the knot and creates a
self-sustaining Tor-style network, one which rewards people who take
the risk of running exit nodes, just as in Anthony's example about
WiFi hotspots.

One technical problem is verifying that a particular exit node is
legit, so that its operator can get his Tor-bucks. It might be enough
to put Tor-money in the packet so that the last node receives it, but
then he could skim the cash without performing the service of letting
the packets go out. Still, this would be easily detected and users
could blacklist exit nodes which didn't perform, so it might be

Obviously an ecash-integrated Tor network is an ambitious project, but
it is something to think about if Tor starts running into problems
with people not wanting to run exit nodes.
