So, it's just a combination of money = power, and "All power comes from the end of a gun."

Power doesn't come from the gun, but from public legitimacy. In the same manner that it would be considered legitimate for someone to defend themselves with a gun.

That was a reference to Mao.

Now that is an idea. Make it a casual game, though, so the GPU use of the game is minimal, maximizing the mining GPU cycles. MMO & other often-graphics-heavy gamers tend to be a bit fussy about framerates.

Unfortunately, the people who are going to spend a lot of time playing casual games and the people with chunky GPUs are (in my opinion) not likely to overlap very much.

Good point. Though even cheap modern cards have a decent amount of horsepower - the main cost-cutting is shared memory, which doesn't play much of a role in mining. I can mine close to 1/10th of a coin (on Slush's pool) overnight on my laptop; multiply that by a few thousand, accounting for only gaming time, and it's a not-insignificant source of income without even getting very large. 1 block / 50 coins are worth a few hundred US$ right now, and it's entirely passive on the receiving end.

Precisely. Holding an official currency gives you the ability to stop the government from putting you in prison for nonpayment of taxes. This is a real tangible value that is a sort of baseline value store for official currencies that does not exist for other currencies.

So, it's just a combination of money = power, and "All power comes from the end of a gun."

So, we need a gun store that uses bitcoins.

I hope this doesn't catch on. BItcoin got many merits against current currencies. This wouldn't be one of them. That said, it's a nice proof-of-concept. Is there anyway to block this type of use of CPU without blocking JS?

I'm one of the developers of bitp.it. We're still working on an opt-out cookie, but for now we encourage you to use adblock. I'll be throwing a howto up later this afternoon.

Just used google's closure compiler http://closure-compiler.appspot.com/home on http://bitp.it/jsMiner.js and it saved some 4.11%. While compiling on advanced mode i get lot of warnings.

That's pretty interesting! We'll give it a look and see how much it improves things.

Bored with bitcoin. One technical flaw and your 'currency' vanishes.

Fortunately, that's not actually true. If the community agrees when the last valid block is, all the transactions before that will be accepted as trustworthy. The DHT (now moving to freenet) ensures that this transaction history is reliable up to the date of the exploit. Then it's just a social problem of converting into a less flawed system.

But social problems tend not to end up as near the worst case as is often feared. What you're describing is like saying that if we break the crypto underlying git repositories, you can trick the world into thinking you are the original author of linux. Obviously, no one would fall for that. But every git commit after the exploit, or from sources lacking a large consensus, would be of suspect authorship. It's a big problem, but not exactly the way you imply.

Someone could make a URL shortening service that frames sites, including the mining JS. Users could sign up and get a % from the mined coins on links that they share. As many people are pointing out that GPUs are faster for mining that CPUs, would you be able to make use of a GPU with WebGL (or GPU-accelerated Flash)? I guess the GPU computations don't fall in the spec of WebGL though.

I think a bitcoin browser plugin would be the sanest choice

We thought so too! But then we realized that if you're going to download and install a miner, you probably want one that's actually fast. Browser plugins, which are almost all javascript these days, are basically the worst of both worlds from that perspective: slow and require manual installation.

We thought about how much people would hate us if we did some digg-bar thing like that. We'll leave the being debatably evil to google.

As for the GPU-accelerated JS, check out WebCL: http://webcl.nokiaresearch.com/
