There are multiple ways to calculate a given document, but the result is always exactly the same. If someone gives a false formula, it is obvious both that it is false, and who is lying, since nodes would be required to sign the statement that they encrypted a particular file with a particular key giving a different file, where the files are identified by their hash. As for the question of whether the very first formula for a given content is correct, that is no different from uploading junk into a CHK and linking to it from a freesite claiming it is a certain movie. -- Ed Huff _______________________________________________ devl mailing list devl at freenetproject.org http://hawk.freenetproject.org:8080/cgi-bin/mailman/listinfo/devl
