    Don't confuse, to complex for you to work out in you head as difficult or even reasonably secure.

    I think this scales as a sort of >O(n^2) type of problem if you want to be more specific on the kind of complexity. That goes well beyond something simply difficult to work out in your head and indeed serves as the basis for much of the encryption methods used today including how Bitcoin itself works for mining and authenticating payments.

    When the number of Bitcoins transferred in and out of a particular address is in the tens of thousands, sneaking a much smaller number into that stack is mostly statistical noise, which is where you can hide your transactions in such a scheme. The longer you wait between sending the money into such an exchange/bank and when you withdraw that money, the more secure you can be assured that it will be hard to trace those coins.

    While I haven't done the actual algorithms to figure out the statistical likelihood, I know it can be done. It sure as hell is far more secure than a 10 character password, and likely a 50 character password. The weak point in one of these cleaning houses is not the method of moving bitcoins in and out of the exchange, but the authentication being used by the website or whomever you are using for that kind of "laundering service". That can be attested to the fact that it has been through the exchanges (my own experience included) that you are more likely to lose bitcoins than through even scam artists skimming a few in a ponzi scheme or some other nonsense.

    The disposable wallets are something you explicitly need to make though. Some of this can be done by default in the Bitcoin transaction software (aka the "client software" that generates transactions) but it must be explicitly done.

    There still is a chain of evidence though that says this particular bitcoin I received came from blocks A, B, C,.... ,X, Y, Z as a chain of custody going back to when they were originally mined. This is a part of the accounting that makes sure you can't double spend the same Bitcoin.

    When you spend Bitcoins, you need to provide evidence that you have those Bitcoins, hence the wallet. You can have multiple public keys that can be unlocked from the same private key (which is what you are talking about in terms of the "disposable wallet), and those are much harder to trace, but in theory you still can trace even those transactions.... once the Bitcoins are spent again.

    Lets say the DEA somehow obtains the wallet of Steve's Marijuana Farm that I mentioned. Since they have the actual wallet information (aka all of the private keys, even if it is multiple keys), they can do this step by step analysis for everybody that sent money to Steve and every transaction in between when the Bitcoins were mined to when they arrived in Steve's wallet. In other words, the anonymity of the purchaser is lost here, even though the privacy of the seller can still be maintained until the coins get spent again.

    You are simply flat out wrong here then. There is definitely an inherent connection between the disposable wallets and your main wallet, assuming you want to spend the Bitcoins. That is sort of the point of the paper in the main post is that your anonymity is preserved until you spend them. Once that happens, the connection between the disposable wallet and the main wallet is established again. All you are talking about here are those additional public keys that can each be unlocked from one or more private keys you might hold to confirm that you are authorized to spend those Bitcoins.... thus the previous transactions are all linked together. You can't find out who Steve is from all of the Bitcoins that are being sent to an address, but Steve can find a whole lot of information about you.

    This is where a DEA (or other law enforcement agency) honeypot could really be a nasty wakeup call for some people.

    Perhaps someone can invent a bitcoin anonymity hub..

    Some of the early exchanges worked just like that and it was even encouraged. You could transfer in a pile of your bitcoins to the exchange and haul them out a day or two later. Since so many bitcoins were going in and out of the exchanges themselves, tracing even large blocks of bitcoins was quite problematic. Basically you had to start and end at those exchanges.

    The problem with exchanges now is the personally identifying information that is linked to accounts. Earlier, the exchanges didn't require anything other than an e-mail address (a throwaway yahoo address worked fine) to set up an account. Certainly an anoymizing hub like you are suggesting could easily be done and trivial to create.

    It isn't quite that, but it is more. Most people use the same traceable money pool where you can trace multiple transactions and use that to track people down. It isn't just Bob's Porn Emplorium, but also noting that from the same pool of bitcoins a transaction took place to Steve's Marijuana Farm, Sally's Whorehouse, and Chuck's Supermarket in Podunk, Kansas. That same pool of Bitcoins might have also received money from several people who are also all blood relatives.

    The point is that each individual bitcoin can be traced from the first work unit where it was "mined" and be followed to every transaction where it was used. Anonymity happens if you change hash values (as individual users can use new public/private pairs to claim individual bitcoins), but it isn't perfect.

Specific legislation was drafted that targeted my ancestors and the people they were with to be exterminated. Mass genocide was encouraged. By moving away, the situation was resolved even though others got to claim the farms, homes, businesses, and other property that rightfully belonged to my ancestors.

    No, I sure as hell don't want another government interfering here and if you think I would you don't know a damn thing about either me or my neighbors. It sounds to me like you want to be subject to a foreign nation as a vassal and live in perpetual slavery to that distant foreign power with no real way to complain or even express your feelings about the conditions you live under.

    Again, why in the hell does America, Britain, France, or Russia need to be involved in this matter at all? Indeed I would say that the current fiasco that is happening in Syria is explicitly because of intervention that has already taken place by other governments, including all of those I mention earlier plus other independent sovereign entities as well.

    You also have this strange notion that somehow all of the nations are under some sort of world government that passes laws which everybody must follow. I would dare say you need to have a bit of a reality check here, as you are living in a fantasy world that simply doesn't exist. Life can be brutal. There certainly are some ethical standards that would be nice if most people followed, and I find murder, theft, rape, and fraud (to name just a few things) to be not just wrong but worth trying to track down somebody who did that evil thing... or at least make sure that person is never welcome in the society you are in.

    You can do that with nations too: If some country is being a real jerk (like North Korea, to give a good example), they can be cut off from trade and scientific cooperation as well as from communications networks in various ways. I completely support doing that to countries who are doing things that my country doesn't agree with.... as determined by the leaders of my government through processes determined by the people in my country.

I expect that is precisely what will happen in Syria, where any invasion of that country by foreign governments only gives further legitimacy to Assad and his government. Not only is it not helpful, but it is counter-productive to picking sides in a civil war where the outcome is far from certain or even if the government that will replace the Assad regime will be any better.

It doesn't sound exactly like a mass consumer item, except perhaps those who want to spend some time on Jerry Springer's TV show (or other talk shows that do DNA matches between random boyfriends and the babies of unwed mothers). A lack of competition also seems to be a lack of customers. No doubt there are people who are willing to pay for sequencing at the current price (including several government agencies for various purposes) along with a few corporate customers who need DNA analysis for various products as well as genuine R&D that can afford the current price as well.

    If the market isn't expanding rapidly with a substantial drop in price, the price is unlikely to drop, hence a substantial flattening of the market price.

    No doubt there could be a real genuine market for hospitals and medical clinics to basically sequence every patient including every newborn for real medical diagnosis.... but the price is not really at the point where insurance companies would pay for this and it is not something an ordinary person would be willing to pay for such sequencing either, certainly not for a full genome analysis. The whole heath care system in 1st world countries is hardly a free market, so that really skews things to basically be a limited number of companies that would end up actually paying for this kind of sequencing.... hence another reason for relatively flat prices.

    A similar kind of market situation exists with orbital rocket launching companies, where the absence of customers is also causing rocket prices to stagnate. Only a relatively recent increase in new markets for spaceflight has there been any real competition... and government contracts still dominate the landscape.

Iran also had a huge manpower advantage, and the war pretty much ended in a stalemate. Saddam Hussein was a huge admirer of Joseph Stalin and even hung portraits of the guy up around his various palaces, with the attitude that if "Uncle Joe could do it, so could I". He also didn't mind looking to Khrushchev for some leadership examples either, including how to stand up to the USA if necessary. The Shah of course was a huge fan of America, and supposedly even had a long-term goal of westernizing to become more of a British style constitutional monarch if possible. The people in Iran weren't interested in taking that much time to transform though.

    American involvement in Iraq was mainly to keep that war as a stalemate instead of letting Iraq collapse and be overrun by Iran. Iran was technically winning the war, and no doubt a united Iran + Iraq would have been formidable in terms of conquering other parts of the Middle East.
