On special objects, and Judy Miller's treason
by Major Variola (ret) 25 Oct '05

25 Oct '05

Its unfortunate that some posters had to be reminded that anyone calling for government-licensed "reporters" (and "religions", as one author included) deserves to have their carbon recycled, because of the treason to the BoR. Tim May used to call government licensed citizens "special objects". Search for it. If state violence is used against "unlicensed" practitioners, then the state controls the practice. Pharmacy provides another example of this --the state controlling what you ingest. It is also sad that no one pointed out that when compelled to go before the Inquisition (aka grand jury) one is not compelled to say anything. So long as the BoR holds. For instance, Dupe Miller could have kept her crudely painted mouth shut, because she could have worried that she would have incriminated herself, eg in not reporting the felony of broadcasting a spook's identity. Or worried about unknown charges that might be brought against her; you never know what prosecutors will dream up. Do not cooperate with fascists, occupying troops, etc. (Speaking of which, are any anonymous offshore betting establishments making odds on Ryan Lackey's lifespan?) --- Impeach or frag.

Re: [fc-discuss] Financial Cryptography Update: On Digital Cash-like Payment Systems

| U.S. law generally requires that stolen goods be returned to the | original owner without compensation to the current holder, even if | they had been purchased legitimately (from the thief or his agent) by | an innocent third party. This is incorrect. The law draws a distinction between recognized sellers of the good in question, and other sellers. If you buy a washer from a guy who comes up to you and offers you a great deal on something from the back of his truck, and it turns out to be stolen, you lose. If you go to an appliance store and buy a washer that turned out to be stolen, it's yours. Buy a gold ring from the salesman at the same store, and you better hope he didn't steal it. As in any real-world situation, there are fuzzy areas at the edges; and there are exceptions. (Some more expensive objects transfer by title - mainly houses and cars. You don't get any claim on the object unless you have a state-issued title.) But the general intent is clear and reasonable. | Likewise a payment system with traceable | money might find itself subject to legal orders to reverse subsequent | transactions, confiscate value held by third parties and return the | ill-gotten gains to the victim of theft or fraud. Depending on the | full operational details of the system, Daniel Nagy's epoints might be | vulnerable to such legal actions. This is no different from the case with cash today. If there is a way to prove - in the legal sense, not some abstract mathematical sense - that a transfer took place, the legal system may reverse it. This comes up in contexts like improper transfers of assets before a bankruptcy declaration, or when people try to hide money during a divorce. -- Jerry

Nuclear Detection: Fixed detectors, portals, and NEST teams wont work for shielded HEU on a national scale; a distributed network of in-vehicle detectors is also necessary to deter nuclear terrorism http://iis-db.stanford.edu/evnts/4249/disarm.pdf Maybe the FCC will require rad detectors in cellphones as part of their 911-location finding / dissident-tracking system? ----- Go for the head shot, they're wearing puffy vests on the tube, mate.

Private records scattered in the wind (FLA)
by Major Variola (ret) 25 Oct '05

25 Oct '05

We encourage the publication of the (paper) school records which the FLA hurricane reportedly distributed to locals, as part of an effort to show the sheeple how *well* the state guards their secrets. Particularly interested in offspring of state officials, not that their kids are likely go to public schools. [FLA is required to bus lower caste students within counties, to achieve a certain average complexion, so even in Jeb'$ neighborhood the schools suck.] --- Impeach or frag.

On the orthogonality of anonymity to current market demand

Though I agree with the notion that anonymity is orthogonal to market demand at the moment, I think you lost me at the word "account", above. :-). That is to say, your analysis conflicts with the whole trend towards T-0 trading, execution, clearing and settlement in the capital markets, and, frankly, with all payment in general as it gets increasingly granular and automated in nature. The faster you can trade or transact business with the surety that the asset in question is now irrevocably yours, the more trades and transactions you can do, which benefits not only the individual trader but markets as a whole. The whole foundation of modern finance, and several -- almost posthumous, so pervasive was the homeopathic socialism that we now call Keynesianism -- Nobel prizes in economics are based on that premise, and it has been proven empirically now for many decades: The entire history of the currency futures markets would be a good example, though now that I think of it, any derivative market, since the time of Thales himself, would prove the point. However "anonymous" irrevocability might offend one's senses and cause one to imagine the imminent heat-death of the financial universe (see Gibbon, below... :-)), I think that technology will instead step up to the challenge and become more secure as a result. And, since internet bearer transactions are, by their very design, more secure on public networks than book-entry transactions are in encrypted tunnels on private networks, they could even be said to be secure *in spite* of the fact that they're anonymous; that -- as it ever was in cryptography -- business can be transacted between two parties even though they don't know, or trust, each other. For instance, another "problem" with internet bearer transactions, besides their prima facie "anonymity" (they're only prima facie because, while the protocols don't *require* is-a-person and-then-you-go-to-jail identity, traffic analysis is still quite trivial for the time being, onion routers notwithstanding) is that the client is responsible not only for most of the computation, but also for the storage of notes or coins, instead of a central database in a clearinghouse or bank somewhere "storing" various offsetting book-entries in, as you noted above, "accounts". :-). Of course, simply backing up one's data off-site, much easier with internet bearer certificates than with whole databases, solves this problem, and, as we all know here, the safest way to do *that* is to use some kind of m-of-n hash, stored, someday, for even smaller bits of cash :-), in many places on the net at once. Obviously, we don't need small cash to store big assets, any more than we need big servers to distribute big files in BitTorrent, but it will only accelerate, if not complete, the process, when we get there. As I have said, too many times :-), about these things, transaction cost is always going to be the critical factor in any change from book-entries to chaumian-esque internet bearer transactions. And I believe that, hand-in-hand with increased security, reduced transaction cost is more a function of the collapsing cost and the ubiquity of distributed processing power and network access than anything else. So, anonymity is, in fact, orthogonal to market demand, primarily because it's an *effect*, and not a cause, of that demand. As we all do now with the current proctological state of book-entry finance, the anonymity of a proposed internet bearer transaction infrastructure will just be a "cost" that the market would have to bear. :-). To channel Schopenhauer a bit, like the emergence of industrialism and the abolition of slavery was before it, once anonymity becomes a "feature" of our transaction infrastructure, people will eventually declare it to be not only self-evident all along, but a moral *prerequisite* of any transaction as well. To put it another way, it's a pity for acrophobics that the fastest way to get anywhere these days is to fly, but it is still a physical fact, nonetheless.
