Just thought this forum needed a Bitcoin thread, seeing as it's a pretty interesting topic.

From the FAQ (http://www.bitcoin.org/faq):
What is Bitcoin?
Bitcoin is a peer-to-peer network based anonymous digital currency. ''Peer-to-peer'' (P2P) means that there is no central authority to issue new money or to keep track of the transactions. Instead, those tasks are managed collectively by the nodes of the network. ''Anonymity'' means that the real world identity of the parties of a transaction can be kept hidden from the public or even from the parties themselves.
How are new Bitcoins created?
New coins are generated by a network node each time it finds the solution to a certain calculational problem (i.e. creates a new block), for which an average solution time can be calculated. The difficulty of the problem is adjusted so that in the first 4 years of the Bitcoin network, 10,500,000 coins will be created. The amount is halved each 4 years, so it will be 5,250,000 in years 4-8, 2,625,000 in years 8-12 and so on. Thus the total number of coins will approach 21,000,000 over time.
So your wealth is determined by the amount of CPU power you have?
No. There's a constant average rate of new Bitcoins created, and that amount is divided among the nodes by the CPU power they use. When Bitcoins start having real exchange value, the competition for coin creation will drive the price of electricity needed for generating a coin close to the value of the coin, so the profit margin won't be that huge. The easier way to gain a lot of wealth would be trading goods.
At the moment, though, you can generate new coins quite profitably, if you expect them to have real value in the future. If you choose to, be aware that Bitcoin is still experimental software.
Why should I use Bitcoin?
- Transfer money easily through the Internet, without having to trust middlemen.
- Third parties can't prevent or control your transactions.
- Bitcoin transactions are practically free, whereas credit cards and online payment systems typically cost 1-5% per transaction plus various other fees up to hundreds of dollars.
- Be safe from the instability caused by fractional reserve banking and bad policies of the central banks. The limited inflation of the Bitcoin system's money supply is distributed evenly (by CPU power) throughout the network, not monopolized to the banks.
Any thoughts? Currently the default software uses CPU for generation, but there are GPU applications on the Bitcoin forums which generate solutions (and therefore bitcoins) much more quickly. I've heard that 20% of bitcoins now are being generated by one person with a GPU farm. I've been running the software for about a week now and haven't generated any coins, but I figure I'll run it for a few months on one of my 4 cores and see what happens. It's particularly interesting that you can trade Bitcoins for cash or vice-versa and even buy things directly with the currency (http://www.bitcoin.org/trade). The Electronic Frontier Foundation (EFF) also recently started accepting donations in Bitcoin. You can read about that here: http://www.bitcoinbl...on-through.html
