15.8.1. "Are there any actual examples of software-mediated reputation systems?" - credit databases...positive and negative reputations 15.8.2. Absent laws which ban strong crypto (and such laws are themselves nearly unenforceable), it will be essentially impossible to stop anonymous transactions and purely reputation-based systems. - For example, Pr0duct Cypher and Sue D. Nym will be able to use private channels of their own choosing (possibly using anonymous pools, etc.) to communicate and arrange deals. If some form of digital cash exists, they will even be able to transfer this cash. (If not, barter of informations, whatever.) - So, the issues raised by Hal Finney and others, expressing doubts about the adequacy of reputation capital as a building block (and good concerns they are, by the way), become moot. Society cannot stop willing participants from using reputation and anonymity. This is a major theme of crypto anarchy: the bypassing of convention by willing participants. + If Alice and Bob don't care that their physical identies are unknown to each other, why should we care? That is, why should society step in and try to ban this arrangement? - they won't be using "our" court systems, so that's not an issue (and longer term, PPLs will take the place of courts, many of us feel) - only if Alice and Bob are counting on society, on third parties to the transaction, to do certain things, can society make a claim to be involved - (A main reason to try to ban anonymity will be to stop "bad" activities, which is a separate issue; banning of "bad" activity is usually pointless, and leads to repressive states. But I digress.) 15.8.3. Part of the "phase change": people opt out of the permission- slip society via strong crypto, making their own decisions on who to trust, who to deal with, who to make financial arrangements with + example: credit rating agencies that are not traceable, not prosecutable in any court...people deal with them only if they think they are getting value for their money - no silly rules that credit rating data can "only" go back some arbitrary number of years (7, in U.S.)...no silly rules about how certain bankruptcies "can't" be considered, how one's record is to be "cleared" if conditions are met, etc. - rather, all data are considered....customer decides how to weight the data...(if a customer is too persnickety about past lapsed bills, or a bad debt many years in the past, he'll find himself never lending any money, so the "invisible hand" of the free market will tend to correct such overzealousnesses) + data havens, credit havens, etc. (often called "offshore data havens," as the current way to do this would be to locate in Caymans, Isle of Man, etc.) - but clearly they can be "offshore in cyberspace" (anonymous links, etc.)
