I think that the reason why you can't find this filesystem is akin to the reason why all-powerful, all-knowing, and all-good god has not been spotted yet.

Here is a solution: Everyone is, as with Bitcoin, identified by a public key - but by quite a few public keys, providing not anonymity but pseudonymity. When you store stuff on someone else's system you issue an IOU, which IOU is anonymously transferable, using a chaumian protocol, which *does* provide anonymity - you pseudonymously store other people's stuff, and anonymously use the resulting IOUs to store your own stuff.

From time to time you check that stuff that is stored on someone else's system is available by random sampling.

When stuff stored on someone else's system becomes inaccessible, you note him as unreliable, and thus decline to issue IOUs or services to him in future, though since IOUs are transferable, you are still up for any IOUs you have issued to him in the past. The software attempts to cancel out IOUs - so that if Bob provides services to Carol, Carol provides services to Edwards, and Edwards provides services to Bob, they cancel out. If someone's IOUs get cancelled out in a cycle of IOUs that include your own, or include those you have confidence are reliable, this is evidence he is reliable in that his IOUs are good. You try to store stuff with those that you have reason to believe are reliable, and with those where storing stuff with them enables you to cancel out IOUs. You give low priority to storing stuff from people whose IOUs you have no reason to believe. Repeating: You pseudonymously store other people's stuff, using a nym that gains reputation thereby, and anonymously store your stuff on other people's systems, using a nym with no reputation. _______________________________________________ p2p-hackers mailing list p2p-hackers@lists.zooko.com http://lists.zooko.com/mailman/listinfo/p2p-hackers ----- End forwarded message ----- -- Eugen* Leitl <a href="http://leitl.org">leitl</a> http://leitl.org ______________________________________________________________ ICBM: 48.07100, 11.36820 http://www.ativel.com http://postbiota.org 8B29F6BE: 099D 78BA 2FD3 B014 B08A 7779 75B0 2443 8B29 F6BE
