It's a very, very, very bloody long posting, and the really relevant- to-you stuff is only near the bottom, but there's a proposal for a file-sharing-and-searching-over-Freenet system, "freetella", basically gnutella + freenet as I understand it. The reputation management stuff is interesting (but full of *#&! math!) in particular, as well as the suggestion that Frost could form part of the back end of this thing too. The reputation management thing may be more interesting than Freetella proper, though, because it seems to offer what are described as, and I can't disprove it, "foolproof" ways to a) make any indexing system based on volunteer contributions to an index difficult to spam or flood or otherwise pollute based on reputation management -- I especially like the notion of contributer identities being in the key strings for their submissions so if they wind up in really bad repute clients can simply not retrieve such keys at all, thus allowing pollution to wither and die instead of persisting, but being ignored, but continuing to burden clients making sheer volume denial of service attacks of such publicly- annotatable indices possible. Such DoS tricks will run up against a brick wall of clients not retrieving or propagating the pollution at all, limiting the damage to one node and its immediate environs. It's like they can dump toxic waste but it won't get into the groundwater. The math stuff has to do with preventing a spammer cheating the reputation management system by making multiple IDs that all vote each other up. It's tricky (Markov chains, what the [EMAIL PROTECTED] are Markov chains for Pete's sake?) and something is "an exercise left to the reader" but he (she?) seems to have found a way to make self-votes, even indirect ones, cancel out somehow. Also, there's no central stuff mentioned, which would have cast immediate doubt on the whole thing. No central reputation management, the reputation management reputation manages its own internal votes as well as whatever larger purpose it serves, no centralized anything as near as I can tell. No vulnerabilities. No dependence on non-Freenet services at all that I can see, aside from the inevitable loopback "spaghetti networking" internal to the node machines involved in everything Freenet, the basic internet protocols themselves, and DNS. Even that might be jettisoned when static IPs are used throughout (IPv6 might make dynamic IPs a bad memory. In a pig's eye.) There's some sort of wacko anti-RIAA stuff in the article too, including an "I don't hate the RIAA, they're just a favorite whipping boy" sort of disclaimer right after a lengthy discussion of how to completely thwart the RIAA *without* freenet or heavy use of encryption. Whether we *should* thwart the RIAA is left as an exercise for the reader's consicence, I guess. The clever scheme involves breaking bootleg files up into chunks to small they are either unintelligible in isolation or fall under fair use, which need not even be encrypted though he seems to recommend some crypto, and are combined into the complete file (and if necessary decrypted) by someone who wants the file. The trick is for no host to offer more than one fragment so there's nothing but an unintelligible, suggestively named (author's own words more or less) or a fair-use quotation being shared, i.e. no probable cause for searching your cpu and finding the rest of the file or even supposing you knew what others were doing with the file. I'm not totally sure they wouldn't find some way to legislate such a thing out of the loophole described, though. In fact, they probably would. There's also some stuff about ISPs relaxing AUPs, freedom of speech, world peace, and so on. Says he's a fellow canadian -- probably a canuck that voted NDP on Monday and commutes regularly to an institute of higher learning then. And before that a long long list of suggestions for improving gnutella most of them seriously technical. I think he also took potshots at bill gates, shareaza, and some other prominent targets besides the RIAA. Oh, and the FBI and other law enforcement agencies of questionable trustworthiness. (Why not mention CSIS?) Oh and he dares them to prosecute him under the DMCA for posting it. Then he thumbs his nose at the yankee gestapo and that's where he announces his canadianness. Hope he hasn't any travel plans to like Florida or Hawaii in the near future then. :) Anyway the freenet-related stuff at the bottom looks interesting. I think the reputation stuff may be quite generalizable for a lot of other stuff. There's occasionally talk of how to influence unwanted stuff into expiring from the freenet here -- reputation management that blacklists keys (and bad blacklisters) in principle lets one stop their machine ever retrieving keys that are on a blacklist for something they don't want to make spread through freenet, e.g. child pornography. A popular blacklist could indeed depress the spread of a blacklisted file, perhaps to the point it can't be found in any data store but that of the one loser who keeps reinserting the thing. _______________________________________________ Support mailing list [EMAIL PROTECTED] http://news.gmane.org/gmane.network.freenet.support Unsubscribe at http://dodo.freenetproject.org/cgi-bin/mailman/listinfo/support Or mailto:[EMAIL PROTECTED]
