Announcing the first release of Bitcoin, a new electronic cash
system that uses a peer-to-peer network to prevent double-spending.
It's completely decentralized with no server or central authority.
See bitcoin.org for screenshots.

Congratulations to Satoshi on this first alpha release. I am looking
forward to trying it out.
Total circulation will be 21,000,000 coins. It'll be distributed
to network nodes when they make blocks, with the amount cut in half
every 4 years.
first 4 years: 10,500,000 coins
next 4 years: 5,250,000 coins
next 4 years: 2,625,000 coins
next 4 years: 1,312,500 coins
etc...
It's interesting that the system can be configured to only allow a
certain maximum number of coins ever to be generated. I guess the
idea is that the amount of work needed to generate a new coin will
become more difficult as time goes on.
One immediate problem with any new currency is how to value it. Even
ignoring the practical problem that virtually no one will accept it
at first, there is still a difficulty in coming up with a reasonable
argument in favor of a particular non-zero value for the coins.
As an amusing thought experiment, imagine that Bitcoin is successful and
becomes the dominant payment system in use throughout the world. Then the
total value of the currency should be equal to the total value of all
the wealth in the world. Current estimates of total worldwide household
wealth that I have found range from $100 trillion to $300 trillion. With
20 million coins, that gives each coin a value of about $10 million.
So the possibility of generating coins today with a few cents of compute
time may be quite a good bet, with a payoff of something like 100 million
to 1! Even if the odds of Bitcoin succeeding to this degree are slim,
are they really 100 million to one against? Something to think about...

Yea, that was the primary feature that caught my eye. The real trick
will be to get people to actually value the BitCoins so that they become
currency.
I would be surprised if 10 years from now we're not using
electronic currency in some way, now that we know a way to do it
that won't inevitably get dumbed down when the trusted third party
gets cold feet.
It could get started in a narrow niche like reward points,
donation tokens, currency for a game or micropayments for adult
sites. Initially it can be used in proof-of-work applications
for services that could almost be free but not quite.
It can already be used for pay-to-send e-mail. The send dialog is
resizeable and you can enter as long of a message as you like.
It's sent directly when it connects. The recipient doubleclicks
on the transaction to see the full message. If someone famous is
getting more e-mail than they can read, but would still like to
have a way for fans to contact them, they could set up Bitcoin and
give out the IP address on their website. "Send X bitcoins to my
priority hotline at this IP and I'll read the message personally."
Subscription sites that need some extra proof-of-work for their
free trial so it doesn't cannibalize subscriptions could charge
bitcoins for the trial.
It might make sense just to get some in case it catches on. If
enough people think the same way, that becomes a self fulfilling
prophecy. Once it gets bootstrapped, there are so many
applications if you could effortlessly pay a few cents to a
website as easily as dropping coins in a vending machine.
