          the one way to make sure a currency is usable in daily trade is for it to be accepted as tax payment by local government.

          More correctly, any fiat currency (to clarify things... as opposed to a commodity-based currency such as a gold, silver, or grain backed currency) is based upon the faith of those who participate in and use that currency to buy goods and services with it in the future.

          That is a huge deal and is much different than simply the mere ability to buy goods and services. A government could collapse, the currency could be devalued, or that faith in general could be broken through a variety of other means.

          Perhaps the most significant example of a faith-based currency (faith in the currency, not based upon religion) was the Iraqi Dinar. After the fall of Saddam Hussein, there were many people who thought that it was going to collapse just as other currencies issued by governments that no longer exist have also collapsed. The Nazi German Mark and the Confederate Dollar are both examples of currencies that inflated in value to infinity (aka became worthless). In the case of the Iraqi Dinar, the Iraqi people were both not exactly pleased with the American occupation, and there really wasn't anything to replace the currency. Surprisingly, due to scarcity (no more money was being printed as the government bureaus making the money were destroyed) and a desire by the Iraqi people to continue on economically, the Dinar actually increased in value. In other words, the Iraqi people continued to have faith in that currency to buy future goods and services.

          While certainly governments getting involved with deliberately inflating currency can destabilize that currency, it is also true that at least for awhile a currency can remain stable due to the faith of the people possessing that currency to buy something with it in the future.

          It should also be noted that this is true not just for fiat currencies "in the real world" but it also applies to virtual economies in video games and MMORPGs. Surprisingly even a single-player video game can still have this impact, where a player may hoard or spend with abandon any virtual money found based upon the principle that either the money is plentiful (or without stuff to buy) or of significant value based upon the supply of that money and the potential to obtain things with it. In the case of multi-player games, it becomes a huge issue if virtual markets open up for exchange of goods and "services".

            Tying fiscal policy to the amount of shiny stuff we can dig out of the ground is far sillier.

            If the amount is fixed, then as the economy expands the available value per coin increases and prices drop: instant, guaranteed deflation, getting worse as the rate of value growth increases. If you want to sell something new into a stable economy, everyone else has to drop their prices to make room for you.

            Fiat currency may require us to appoint agents to keep the money supply and the value supply roughly in sync, but at least it provides the mechanism to do it. With the ooooh-pritty-shiny-stuff system, so appealing to people who can't think when there's pritty shiny stuff in sight, money and value are absolutely guaranteed to get out of sync, badly. very fast, with no remedy at all. Unless of course the economy is totally stagnant, with no new wealth being created. Yeah, that's what we want.

              Most people don't understand economics other than having the largest pile of money compared to their neighbors (or complaining that their neighbor has a bigger pile than they do). Wealth creation isn't generating the money itself, but rather what you can do with that money in order to get others to do things for you. If you don't understand that distinction, then it is a hopeless cause at trying to understand economics at its most basic form.

              Wealth is ultimately the blood, sweat, and tears of somebody working their behind off to make something, and all of the rest of money flows from that effort. There may be physical materials involved along the way, but you are paying either directly or indirectly for somebody to extract those materials, to shape it and mold it or do something with it. The currency then becomes a more or less averaged value of whatever it is that you are doing compared to what everybody else is doing. Yes, governments can get in the way via taxes and subsidies to screw the system up and give incentives and disincentives for certain kinds of activities... and to suck up some of that wealth by the "rulers" of that society in exchange for hopefully some civil tranquility, but it all ends up being an exchange of goods (made with labor) or services (simply paying for somebody's time more directly).

              It really makes no difference in the long run between a fiat currency and a commodity currency anyway. Both require acts of faith, and the medium is relatively neutral in terms of whatever it is that you are trying to obtain above and beyond the pile of money in the first place. Even gold requires faith that somebody will accept it in the future, and it has the additional problems of extreme weight and being useful only for major transactions (due to its high intrinsic value). Any concentration of gold also requires couriers and potentially body guards and other sorts of security that end up simply costing more money than it is worth. It is also placing faith that the gold won't be devalued at some point in the future.

              If, for example, somebody discovers a gold nugget on an asteroid that is the size of a house and can relatively cheaply bring it to the Earth, it would cause the gold markets to crash real hard. Gold would still have some value afterward, but it wouldn't be pretty for those who have invested large amounts of their labor into gold.

        Money is money because people believe it is money. Gold-backed currency needs to have people believing that the government is actually going to turn the currency into gold (and not, say, end the gold standard). And if you trust your government enough to do that, today's system isn't much more of a stretch: trusting the government to keep the value of your currency "relatively stable" without any particular commodity attached to it.

        And commodity prices are subject to wild swings too, you know.

                Is by taking it out of circulation. Most of the gold we've mined isn't used for anything, it is simply inspected and then put back underground, only this time in a hole humans dug that we guard. It is artificial scarcity. The gold is there, it could be used, but it isn't because it is "backing" something. So it sits in a vault doing nobody any good.

                Also, who says finite is good? What happens when the economy grows to the point that you need more gold, but none is to be had. Well then you start experiencing deflation and that is a very bad thing. Deflation is a wonderful way to get people to stop spending, stop lending, and as such to freeze the economy. Remember: Money is only good if you can spend it. Moreover, money is only good if you DO spend it. If everyone hordes money and doesn't spend it, well then what really is happening is people are refusing to trade. That means the economy stalls.

                As you say, gold is only worth what it is because western cultures have an obsession with the shiny stuff and it is used as a hedge. It's real value, in terms of industrial use, is far lower. All those idiots who get gold in preparation for the collapse of society would be sorely disappointed if such a thing ever happened. Gold would be near worthless as it has few uses in a non-industrial society (basically only as decoration) and thus would be worth fuck-all as a currency in a survivalist world. More likely, Metro 2033 has the right answer and bullets would be the closest thing to currency out there (it would mostly just be direct barter).

      from wiki []

      Whenever a Bitcoin user makes a transaction, their node broadcasts the transaction to the network of nodes. When transaction data is received through a node, the node begins a proof-of-work calculation in an attempt to create a block containing the transaction. All nodes essentially race to create a block, as the first one to create a block gets Bitcoins as a reward. Once a node successfully creates a block, it broadcasts the block to the network. Other nodes receive the block, perform a proof-of-work check, and add it to their chain if it is valid. As more transactions occur, blocks are created and added ad infinitum. The longest proof-of-work block chain is acknowledged to be the oldest and most reliable account of the online transactions.

      This mechanism is claimed to be virtually tamper-proof. For an attacker to manipulate the record, he must outpace all of the other nodes on the network to produce the longest proof-of-work.

      The assumption that the longest one is the oldest and most reliable is invalid, Since anyone can peer, there's no reason that a peer can't fake itself as 20, 30, 100 peers, and, working on a very fast machine, produce a longer chain quickly than an older peer.

      I've been involved with the Bitcoin project for a while, and there are steps in place to prevent this. Essentially, the network tries to maintain block generation at a rate of six blocks per hour (one every 10 minutes) by checking every 2856 blocks (nominally 2 weeks) if the rate was too high or too low. At that point, all nodes adjust their hash target such that it gets more or less difficult to generate blocks. The net result is that more nodes or faster nodes can only really influence the market for 2856 blocks. There is discussion about reducing this number to lower that time, as well.

        everyone else combined, than to undermine the system and the validity of his own wealth."

        I don't buy this argument, as found in the PDF file about Bitcoin. Mind you, I'm just skeptical here and not trying to say it is impossible to resolve, but I don't see the protocols or transactional security which is dealing with this issue.

        "Although it would be possible to handle coins individually, it would be unwieldy to make a
        separate transaction for every cent in a transfer. To allow value to be split and combined,
        transactions contain multiple inputs and outputs. Normally there will be either a single input
        from a larger previous transaction or multiple inputs combining smaller amounts, and at most two
        outputs: one for the payment, and one returning the change, if any, back to the sender.

        "It should be noted that fan-out, where a transaction depends on several transactions, and those
        transactions depend on many more, is not a problem here. There is never the need to extract a
        complete standalone copy of a transaction's history."

        I'm really curious about this particular issue and how a complete copy of the transaction's history doesn't need to be maintained. Again, it gets to the coining of the money issue, where it would seem as if the transaction trace would have to go back to when the money was coined in the first place. Some sort of planned decay of the history certainly could be used in terms of suggesting that after a certain amount of time it can be presumed that a certain bit of transaction history if valid (using a variety of metrics to make that happen that could even go beyond a pure timestamp measurement). Still, the option to view the full transaction history for what fan outs and inputs were associated with that transaction seems like a critical feature.

    A base value for bitcoins is assumed to be the energy used to create it. The system itself appears to be far more profitable when operating at am exchange entity or trader. ie, the ability to control the effective value of the coin in question. Which lends the whole process to feeling more like a pyramid scheme than anything else. Now, if you wanted a lossy system that was anonymous and had morally bankrupt exchange locations it would be useful anywhere an anonymous transaction is a must.

    On the flip side, because wealth is always being generated for free, a purpose built rig which excels at generating coins more efficiently would essentially be a living cash machine. This would in effect mean that the coin itself has no actual value. It's worthless because it cannot be returned to the previous state. This is somewhat important to me when a system is based on the trade of goods.

    In terms of actual exchange it introduces to much latency to ensure the transaction is actually valid. In terms of instant gratification the whole thing begins to break down.

    The good news is that anybody is certainly free to use it. Unfortunately, because anyone can print money (even small amounts) I'm not going to be giving up any of my items today.

    So this system requires CPUs to burn scarce, real electricity in order to generate virtual electronic tokens whose only purpose is to simulate the scarcity of rare metals, so that we can continue to use the old 'exchange value' economic model in the realm of information where by definition, it does not apply.

    This seems like basing an economy on burning one's food crops to prove wealth and using the ash to buy things. I'm sure it would 'work', for some definition of work, but it doesn't seem particularly... efficient. Or sensible. Granted, humans do indulge in self-destructive behaviour, but do we really have to port all our bad habits into the digital world?

    Is there some actual upside to this system which I'm not getting?

      Not to mention that Moore's Law would cause runaway inflation. And wouldn't people with access to supercomputers (University profs and students) become disproportionately wealthy?

        At 100% every 18 months, it will soon be less inflationary than the US government's fiscal policy (if not already)?
    • At least they aren't mining rare metals that make up less than 1% of the earth's surface, or cutting down trees and using a great deal of energy to pulp and dry them.

      What would you suggest for an economic basis for universal exchange, if not paper or precious metals?

      No, it requires computing power. It just happens that electricity-based CPUs are the most powerful method we have to compute at the moment.
      But you could just use pen and paper, or even just your brain.

    Since the site is down and the summary is light on information, let me try and summarise this a bit better, from what I've picked up, so I might be wrong on some of the details):

    Nodes connect to each other in a P2P network.
    The nodes perform hashing problems, attempting to find a number that hashes to a value with a certain number of 0's at the start (binary zero's, aka, the number has to be below a certain value)
    The network assigns bitcoins to those nodes who have found solutions to the hashes.
    After a certain amount of time the difficulty of finding the hashes increases(an extra 0 is added to the hash solution required)
    This increase in difficulty continues until eventually there will be 21million bitcoins and no more can exist.

    We are currently in the inflationary stage, so the supply of bitcoins is increasing. once all 21 million have been assigned, then it will become deflationary, as no new coins can ever be created and coins that are lost are lost forever.

    bitcoins can be divided into 100 million pieces, so the limit of 21 million coins is not a major stumbling block.

    Essentially it's a way to create a decentralised currency with a hard limit on how much is available, ensuring that it cannot be inflated by a central government simply printing more cash or adding some numbers to a computer system.

      If there is a hard limit to the total amount of currency that can exist, then what you have is a situation where the currency will not scale with the economy. That means deflation and there's no faster way to kill an economy than that.

      To me it seems like the people who created it are the same kind of gold standard 'tards who cry on and on about inflation without understanding it. They see inflation as "eating up your savings" (which is doesn't so long as you put them in an interest bearing account) and thus think deflation would just be great. I mean you have more buying power for doing nothing! Wonderful!

      Except it badly fucks over an economy. For one, it simply drives down spending. If you can get something for a dollar today, or two of that something for a dollar next week, it makes sense to wait as long as you can. Non-essential purchases are discouraged since the longer you wait, the more your money gets you. While that sounds like it encourages savings what it really does is screw over trade. Money only works if people spend it. People can have as much money as you want if nobody spends it it is worthless, regardless of the form it takes.

      Then there's loans. The ability to make and receive loans goes to hell in a situation of continual deflation. Unless the loan is extremely short term, it won't work. Take a house loan. This is doable because even with minimal to no inflation, you know you can afford it. You know your cost will not go up in percentage terms. However with deflation? No such luck. In a situation of continual deflation, the amount of money you receive for work will go down with time. As such the payments on a loan will be a larger and larger part of income, growing until you can't afford them. To make it work, the loan would have to be offered with a negative interest. But nobody will do that, they'd simply not loan out their money instead as that is a higher rate of return and is guaranteed. Currently people will make loans because the risk of the loan is balanced against having a positive return.

      I could go on, but deflation is an extremely bad thing in the long run, and with a fix currency supply you have guaranteed it. Sounds like your project needs less gold standard survivalist geeks and more economists. Tell you what, run your idea by Dr. Gerry Swanson, you get him to sign off on it, maybe I'll reexamine it. As it stands now it sounds like an extremely bad idea just from an economics standpoint, never mind any technical arguments.

    The system is secure as long as honest nodes collectively control more CPU power than any cooperating group of attacker nodes.

    Good luck with that...

Any sufficiently advanced technology is indistinguishable from a rigged demo.
