Generating Bitcoins using Online Ads

Fri, 02 Aug 2013 00:00:00 +0000

After reading about using online ads to launch a javascript based DDoS attack I started wondering about how well such a system would do at mining bitcoins. These are my rough calculations.

From my research I’ve found there are 3 ways to mine bitcoins(compute hashes) using Javascript:

UI thread (I was seeing about 800 hashes/s)
Multiple threads via WebWorkers (I was seeing about 13000 hashes/s)
Using the GPU via WebGL (limited browser support couldn’t find working example).

I based my numbers on this implementation: (http://bitcoin.biniok.net/gl.html) running chrome on a pentium 4. The rates are averages over 5 seconds.
