For me it would be the anonymity and the simplicity. Much easier to simply go to a url which already includes my address and start mining right away, without the need to manage an account.

While novel, there is no way this could be profitable for anybody.

1000 hashes per second?  This is 600,000 times slower than an ATI Radeon 5970.  The power consumed would vastly exceed anything this could produce.

Companies claiming they got hacked and lost your coins sounds like fraud so perfect it could be called fashionable.  I never believe them.  If I ever experience the misfortune of a real intrusion, I declare I have been honest about the way I have managed the keys in Casascius Coins.  I maintain no ability to recover or reproduce the keys, not even under limitless duress or total intrusion.  Remember that trusting strangers with your coins without any recourse is, as a matter of principle, not a best practice.  Don't keep coins online. Use paper wallets instead.

Sorry, I didn't make it clear - if it says 1000, you're getting 1000 kilo hashes per second, so 1 Mhash/sec. As CPU miners go, it is slower than one of the C miners, but that's the tradeoff of having it work from the browser.

I'm curious why you guys would like that feature - is it just to make it easy to stay anonymous? If you're worried about that then until I have this feature you can give a fake/temporary email - I don't validate it, it's only used to email a link to reset your password in case you forget.

Are there other reasons? It's helpful as a developer to know why users want a certain feature, to make sure I give you what you want.
I own several websites where people can donate (no BTC for now). It would be a simple way for them to donate this way and add BTC donation at the same time.
More simple => more users.

You're right, that would be an extremely simple way to let your visitors donate BTC. It wouldn't really cost them anything, just a bit of CPU time.

That would be awesome. I'm going to have to work on that tonight...

It would be like ads, except the website owner gets paid for having a website that people want to stay on, rather than for simple number of pageviews / click throughs.

How about I let you be one of the first to use it (do you have a website?).

For people who are interested in this, being able to embed a miner in your website so that your visitors generate BTC for you, either reply here, PM me, or send me an email at donny@bitcoinplus.com and I'll let you know when it's ready.

I don't know about yous but this seems wrong for a single 5850..



But I have to ask, you say it's PPS and while the page only takes 330Mhash to prevent lag the payout amount should go up after 5 min.. Or maybe I've mistaken it for a profit counter in which case you should add one..

This site is strictly a CPU miner at this time and doesn't support GPUs.

If it takes 5 hours to produce 0.0003 BTC

Then 33 x 5 or 165 hours to produce 1 bitcent

Which is worth less than a dime

Average computer uses 200 watts

That's 1 kWh every 5 hours (200W = 0.2kW; 0.2kW * 5h = 1kWh)

Or 33 kWh to produce a dime

Most people pay more than a dime per kWh

So this is a way to make someone else pay $3+ to earn you a dime

Why not just have them mail you their empty soda cans ... They will pay $3 in postage and then you can go recycle them for a dime

The economics are the same

A thing that pays webmasters for the amount of time people spend on their pages without depending on the user clicking on advertisements, nor polluting the contents of the page and not even depending on a central provider? Dude, that's fucking awesome!!! Cheesy

(I dont always get new reply notifications, pls send a pm when you think it has happened)

Wanna gimme some BTC for any or no reason? 1FmvtS66LFh6ycrXDwKRQTexGJw4UWiqDX Smiley

The more you believe in Bitcoin, and the more you show you do to other people, the faster the real value will soar!

The payout amount is the current payout, not total. If you want your total, register an account and go to the "my account" section.

That's based on the assumption that people are running this on a computer that would otherwise be off. It's pretty good about CPU priority, my computer is perfectly usable while this is generating.

What's the math behind an idle computer and a CPU maxed computer?

And yes, compared to GPU mining CPU mining is inefficient - but this is something that could get people interested in bitcoin who otherwise wouldn't take the time to set up a miner. I'm thinking of this as a kind of entry-level miner (at least until there are ways of doing GPU mining from the browser).

This isn't useful for me as I'm doing all GPU mining, but well done on a great idea and good implementation! Good luck with this project!

Thanks Smiley

You've got your bitcointoss website, would you be interested in putting an embeddable miner on there?

Edit: Just realized it's not yours, you've just got an affiliate link. Nevermind.

I really like the idea and overall a pretty good implementation for a first go around. GPU Mining support would be a huge plus, but improving the performance of the current CPU mining implementation really needs to be done.

Using your site, my Core2Duo 2.2ghz gets about 660KHash/sec. Using Ufasoft's SSE2 miner, it gets ~5,500KHash/sec. I know that you are using Java and so can't exactly write to the instruction level of the hardware, but there should be some sort of optimizations that can help out at least a little bit.
