Bitcoin Releases Version 0.3
Teppy writes "How's this for a disruptive technology? Bitcoin is a peer-to-peer, network-based digital currency with no central bank, and no transaction fees. Using a proof-of-work concept, nodes burn CPU cycles searching for bundles of coins, broadcasting their findings to the network. Analysis of energy usage indicates that the market value of Bitcoins is already above the value of the energy needed to generate them, indicating healthy demand. The community is hopeful the currency will remain outside the reach of any government." Here are the FAQ, a paper describing Bitcoin in more technical detail (PDF), and the Wikipedia article. Note: a commercial service called BitCoin Ltd., in pre-alpha at bitcoin.com, bears no relation to the open source digital currency.
As someone pointed out, this article is light enough on source material that it may count as more of a slashvertizement. That said, if Bitcoin, or any micropayment and/or e-cash plan scales beyond a certain level, it's gonna attract both criminals and government interest and intervention, much as age-old Islamic halawa got a lot more notice when used by gangs like Al-Qaeda.
Luke, help me take this mask off
Given that the gold standard is gone, I'd like to see those guarantees too. Your paper money is virtual as well.
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?

In practice the quantity of gold/silver/etc available is not fixed.
Tomorrow someone builds better mining equipment and suddenly there's 5 times as much available.
A ship loaded with a significant quantity sinks over the mid atlantic trench?
well in practice it has gone beyond where humans can practically access it and so might as well no longer exist.
Alternatively someone might build some kind of Von Neumann machine which can extract your precious metal from seawater or mine asteroids and suddenly the value of your precious metal would drop close to zero.
Whenever someone invents a cheaper way to mine gold you're going to experience price inflation as the gold in your safe becomes less valuable.
gold is only special to people who delude themselves that it's somehow special.
Food, clean water, tools, feminine hygiene products, useful information.
If you're convinced fiat currencies are going to collapse these are what you should be filling your underground bunker with, not some shiny metal which will only be worth anything if people believe it has any intrinsic value.
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.
As always, all IMO. Insert "I think" everywhere grammatically possible.
Good luck with that...
