Hi everyone,

I've just pushed the source of my WebCL open source bitcoin miner here : https://bitbucket.org/dalsh/jsoclbm
This is mostly a javascript port of poclbm. This miner does not use Nokia's Firefox extension. You must download a nightly version of Firefox which includes WebCL. You can find this here : http://gfx.parapluie.org/2011/binaries-for-webcl-and-source

Once it's installed, you can try the project here : http://jsoclbm.parapluie.org/

Any comment will be welcome but I'm quite new to the bitcoin world so please indulge any issue that is bitcoin related in this project Smiley Please also note it is not finished.

You can tip here if you wish : 1Ah4hy4b6qvRBgFQr8uPSGE7GjZwx3yWag

According to NIST and ECRYPT II, the cryptographic algorithms used in Bitcoin are expected to be strong until at least 2030. (After that, it will not be too difficult to transition to different algorithms.)

WebCL is disabled by default and it'll probably stay like that for long

I'm using it right now. What's the problem ?

I don't see a problem with having a WebCL miner, that is, unless you are mining without asking the user.

The miner however seems to pause when I switch the tab until I return to the tab the miner is on (Nokia WebCL version)

That's a bitch for miners that want to do work in background, but it's a VERY nice feature I hope stays if the user doesn't accept a popup request to gain permissions or something. It'd suck to try to tab out and have whole computer sluggish on another youtube page or something that accesses video processing power.

This would make it super simple to setup a mining farm.

I assume there is multi-GPU support.

I hardly think Javascript & WebCL would be more efficient than C and OpenCL.

He forgot to add the word 'botnet' before 'mining' ... since that is really the only valid reason for this.
Any excuse they come up with is just total bullshit.

Who in their right mind would want to use up buckets of CPU/GPU and mine at a much slower rate than any readily available mining program?
... especially since at the moment there is no way you could do this so that it would cost less to mine that the BTC you would earn when the miner itself would be slower than a dedicated miner that already is borderline to running at a loss
Again it's just people trying to steal CPU/GPU cycles or idiots mining at a loss.

Those trying mining for the first time to see what it's like.  Those supporting the network in case of a 50+% attack.  Those wanting non-technical friends to contribute their idle GPUs to a charitable cause.  In each case, mining efficiency is less important than low set up overhead.  There are probably dozens of other use cases that I'm not creative enough to discover.

Do you need your browser to be set up a certain way? Does this product work with all browsers?
