As a public key is just a big random number, they are essentially "anonymous" unless the key is linked to your identity somehow - for example, because somebody you traded with told the police "I sent X coins to Eldavo John and he used address Y".

      That's why it's better described as pseudo-nonymous rather than fully anonymous. It's possible to break the anonymity if people co-operate. I'd say it provides about as much privacy as the regular internet does. An IP address is basically private to regular citizens. If you represent law enforcement and turn up at a bunch of companies with the right paperwork you can make everyone work together and the privacy of the IP address falls.

      It can never grow very large because you need a pretty expensive infrastructure even to handle BitCoins and the only interests it serves will be those industries that want easy untraceable ways to exchange value for illegal products or to avoid taxation.

      Well, to handle Bitcoins today all you need to do is install and run the software from bitcoin.org. It runs just fine on regular servers, desktops and even laptops - hardly expensive infrastructure. If the system takes off and traffic levels reach PayPal levels, running it on a laptop won't be feasible anymore, you'll need some kind of high end server. If the system really takes off and starts matching VISA, a node would have to be distributed and might take a rack of machines. It never really gets infeasible because there is a "lightweight mode" in which the resource requirements are much lower and the security properties are slightly weakened. In this mode it's quite possible to run the system on a smartphone. Your device is independent, but if somebody is able to overtake the networks hashing power it can be made to believe anything. Right now that's 1-2 terahashes/sec, not something that's going to be beaten by anything except rich, sophisticated organizations (big tech companies or governments).

      But I think your question/pondering is more about whether Bitcoin has value beyond mischief. I think it clearly does, otherwise I wouldn't be working on it ;) The existing electronic payments system isn't that great, really. To pay for something instantly over the internet today you have to use credit cards. Wiring money is an alternative but due to outdated banking systems it's extremely slow, money moved this way often moves slower than a physical truck would even though the transfer is actually electronic. It's also quite expensive.

      Credit cards have a bunch of problems for both buyers and sellers. For sellers the biggest problems are chargebacks and the costs of taking part in the system. It's really hard to handle chargebacks. Big companies use sophisticated risk analyses to try and spot unusual behavior, smaller companies just bump the price of everything by 10% to handle the fact that some payments just won't happen. The costs of taking part are also a problem. You can't just install some software on your web server and go. Credit card details are basically big passwords, but in an inconvenient form that you can't change and that every merchant you buy things from must be given. Unsurprisingly, this is totally insecure even with the PCI auditing process that is intended to ensure merchants keep CC data safe. See the recent Sony breach for an example.

      Credit cards aren't really great for buyers either. Whilst chargebacks are useful, you can't opt-out of the ability in order to get lower rates from the merchant, or set up some other kind of escrow scheme. For another, the system is very inflexible. Whilst you can theoretically take steps to secure your CC credentials better on your end, the fact that you share them with anyone you buy things from makes such effort mostly worthless.

      Bitcoin satisfies both points 1 and 2 - but, note that this has to be a "claim on the issuer". Bitcoin does not have a specific issuer. The closest you might find are the miners, who create new currency, but I think a clever lawyer could argue even they are not really "issuers" because they cannot control how much money they create, and the money that is created is assigned to the miner not anyone else. It'd be more accurate to say miners are collectively rewarded by all of the systems participants for securing the network, with a de-facto agreement that finding a block rewards you with coins.

      But even if you define a miner to be an issuer of the currency, Bitcoins do not represent claims on them. Miners have no obligations to accept Bitcoins in return for anything. There are no guarantees made by anyone that Bitcoins can be redeemed for anything in particular. For this reason I think it's unclear whether the FSA rules would apply. The rationale for the rules makes sense as long as the e-money issued is backed by something else, which was a pretty reasonable assumption until Bitcoin came along. The rule that says e-money issuers must have at least 1 million euros in liquid assets has no rational basis for miners however, as miners do not back the currency.

      At any rate, this will be an interesting discussion between lawyers and regulators in coming years I'm sure. One thing to bear in mind is that it's not necessarily (as so often painted) an "us vs them" fight. One reason Bitcoin is interesting is that it lets people be more independent of banks. Politicans know that in the wake of the financial collapse there has been a crisis of trust and confidence in banks. Many ordinary people are quite disgusted with how bankers gambled with the system, were then bailed out and immediately went back to paying themselves massive bonuses. What's more whilst all politicians agree the system is broken, none of them have been able to propose convincing solutions. Basel 3 etc are incomplete at best.

    The fascinating thing there is how Wizards "tricked itself" by misreading how certain cards form gamebreaker combos. So then they embarked on an elaborate "currency value adjustment" program, aka Type 2. (With all the spinoffs etc. In my areas "1.5" and "Legacy" and so on were never very popular.)

    By being relegated to "Type 1" All those power cards were effectively cordoned off into a backwater, and lost most of their effective value. Then as the years rolled on, once cards left Type 2, they also dropped in value like a stone.

    What's to keep the BitCoin administration (does that make sense?) from "adjusting" it later to suit some agenda?

    To me this seems like just more hype, but trying to go at it from a scare part: "Oh these things are so amazing and dangerous that the government will ban them!" Trying to play on people's love for things forbidden.

    Of course it is also rife with problems, one of the biggest being the whole deflation thing. Deflation is something that strangles an economy badly. People want to spend as little as possible, since you get more for the same money in the future, which of course means there is little spending and little spending means little trade which means the economy goes to shit.

    Anyone who is in love the idea of deflation because "My money will be worth more," need to go retake ECON 201 and learn what money really is and why we have it.

    Any current that has built in deflation is a really. really, bad idea.

    Why is it that every explanation of bit coin, including your attempt, is incoherent. Given it can't be explained I think it's a scam.

    I have many questions in part because the basic schema is not clear. I've watched the videos and read the sites. But there just is no explanation that makes a whole coherent sum and there are contradictions when you piece the various explanations together.

    1) On a torrent network, not every node knows where all the slices are. Not all nodes are in communication. Thus what happens if I sent 30 bit coins to Amy and then I sent the exact digital copy of those coins to Brad who is on a network remote from Amy. It sounds like Amy will query the local network to see if I own the coins and so will Brad. But because those queries never intersect on the same node both appear to be valid when in fact I just copied the money. Later on perhaps the system can't reconcile two people owning the same coins but by then I'm gone.

    2) Suppose I send money to Alice. then a fraction of a second later Alice tries to send the same Money to Bob. How does Bob determine that Amy owns the coins? No node on BoB's network can validate my transfer to Alice.

    3) the description has this trail of signed hashes being appended. Does this grow forever and can it be inverted to follow the money?

    4) is each coin signed? or is it transactions?

    5) if someone invents a way to make coins cheaply does this doom the system? What regulates the produciton rate? does this work if I have 1 million different user identities? if there is a central signing authority for this then what keeps this from getting cracked or printing their own money to flood the system?

    6) what happens if botnets start mining?

    how does this actually work, end to end, technically not operationally?

      Why is it that every explanation of bit coin, including your attempt, is incoherent. Given it can't be explained I think it's a scam.

      My explanation mostly focused on the problems of credit cards ;) Bitcoin can be explained. Lots of people understand it. I understand your reaction, but "this is complicated" does not imply "this is a scam".

      Let me try and address your questions.

      (1) Bitcoin is a P2P mesh network. All nodes know about all transactions because they are broadcast. This is similar to how routers on the internet know where to route packets: all participants maintain a shared data structure. So there are no transactions that "never intersect".

      (2) This is a "double spend". The answer is that one of them will win. Because of how transactions are broadcast a delay between the transactions of only a second means the first is much more likely to win than the second. But if you were to try spending the same coin to two destinations simultaneously the network would become briefly confused and which one wins would be hard to determine. After a few minutes a block will be found and the confusion will be resolved: there will be a clear winner.

      (3) You can see the "trail of hashes" (actually signatures) at the block explorer. Conceptually it grows forever. In reality it's possible to delete transactions that are old enough, though the software people use today does not implement this optimization. So storage requirements won't grow forever, they are proportional to the amount of outstanding coins waiting to be spent.

      (4) Oddly enough there's actually no such thing as a bitcoin, in the system itself. Transactions combine and split value. For example a transaction may import 30 BTC and then have two outputs, one of 10 BTC and another of 20 BTC. Those outputs are now available for spending. You can see this in the block explorer which may make it clearer.

      (5) Yes, like any currency the ability to forge perfectly dooms the system. Example: at one point South Africa had to recall and destroy all copies of a particular type of bank note because a Nigerian gang found a way to make perfect forgeries. Bitcoins can't really be "forged" as such because the way they are created is by a form of mutual agreement amongst all parties. The closest equivalent would be if elliptic curve cryptography was broken. ECC has been around since the 80s and is extensively peer reviewed. It's believed to be just as good as RSA. The production rate is regulated by the difficulty rules. Coins are distributed in type of lottery amongst the people who are securing the network with their hash power. This is where things get complicated and if you want to learn more about that I suggest you read Satoshis white paper.

      (6) At current network speeds a botnet of around 500,000+ machines could delay payments from going through or re-order them, allowing reversal of transactions. It doesn't open the system to arbitrary changes like stealing other peoples coins or creating value out of thin air (exception: "lightweight mode" clients as I described before, but nobody uses them today). There are only a handful of botnets that large, mind you.

      If you have further questions you could try Satoshis paper, IRC or the forums.

    This is not to say that all Libertarians are ignorant, but that Bitcoin appeals to Libertarian ideals and requires ignorance of how money works to be sold. Bitcoin has no in-built velocity. Taxing authorities won't accept them and having a fixed amount of them means that they don't have a debt-based life-cycle as does the money most of us claim ownership to. Also, even if Bitcoin were to take off, as demand for it increased, it would create its own valuation bubble where it becomes more valuable to hold the money than it does to invest it. Nobody would be able to borrow in Bitcoins at a reasonable rate of interest, real demand drops, then speculators are left holding a bunch of worthless digital currency. If you think that Bitcoin is a good idea, you are likely in need of an education in economics and accounting and need to lay off of the conspiracy theories.

      This comparisons fails in that Tulips were never truly scarce to begin with. Once traders realized the value in trading or growing Tulips, there was a gap of time in which people wanted more Tulips but the need could not be met, which caused them to rapidly gain value. Since tulips were scarce until more people could finish growing them to be sold. At which point they devalue to the point of nothingness.

      This specific type of quick market inflation then crash is, by design, impossible with bitcoins. The supply of bitcoins entering the economy is constant and predictable (about 50 every ten minutes).

      Note: I'm not saying that the market couldn't crash or won't crash, I'm just saying if it does, it would be for completely different reasons.

    Bartering is still taxed the same as income in every state I know of, and still counts as income for federal income tax purposes. E.g., if you give me a sheep for fixing your PC, I just had a taxable event at the prevailing market rate for one sheep. This is true whether it's goods or services that are exchanged. It does allow for some wiggle room in your valuation perhaps, but everything's negotiable anyway, so there's not much advantage over bartering. OTOH, it may be a bit easier to get your money back than to get your sheep back when you find out that the grain I exchanged was spoiled. Additionally, being left with a pot full of BitCoins when the music stops is like having a jug full of babysitter tokens -- absolutely worthless if nobody else wants them. The same is true of any fiat currency of course, or even backed currency if the underlying asset becomes worthless. The difference is that the full faith and credit of the US government probably carries a bit more weight than the full faith and credit of an anonymous internet startup. For now, anyway.

    The soundness of Bitcoin's crypto doesn't seem to have been analyzed by third parties yet. There's nothing in Cryptologia or sci.crypt. Until there's agreement in the crypto community that it's sound, I'd be suspicious. There's also the problem that if the money resides on user PCs and smartphones, the usual attacks on those devices can steal it. Once stolen and used, there's no way to get it back.

    Transactions are not very anonymous. If you spend a coin with a server, the server now knows your public key, and can associate it with any other identity information it has for you ( IP address, Facebook login, shipping address, etc.) If Amazon, eBay, Google Checkout, or Facebook accepted bitcoins, they'd be able to collect this info for a sizable fraction of the online world. Since your public key remains associated with the coin for at least the next few transactions, it's possible to follow the money.

    Systems like this detect duplicate spending of the same item, but you can't tell if someone has a duplicate but unspent copy of your coins. So you don't know your money been stolen until you try to spend it.

    There's also the technical problem that "new transactions are broadcast to all nodes". That won't scale.
