As you may already know reCaptcha uses that info you provide to correct scanned books/documents. You do the work for free. Those documents will
eventually drive traffic to them. I heard they may start paying in BTC for work submitted. Does anyone know more?

I would like to make a captcha that helps to solve a hash.  I'm not sure if it will work yet.

How does solving captcha's solve a hash?

Even if you could make a captcha which solves a hash, getting 1 million users a seconds (on average) to solve them is still a nearly worthless 1 MH/s.  In reality you are talking about maybe 50 captchas per hash (or more) and Bitcoin is a double hash and say users have a 20% error rate. Yu are looking at up to 100 million captchas to make a single MH/s

BTW at current prices and difficulty 1 MH/s is worth about ~$0.12 per month.  So while you probably could deconstruct a hash into math problems solved by humans the value of that effort is negligible.

Didn't know that, so will google be sending us all tax forms for the work we provided? I'm not sure what the tax implications are but they must have to include all reCaptcha work time submitted and file that with their taxes.  I didn't volunteer so some other contract law comes into play. I'll have to consult the tax man. I'm thinking on the lines of a 1099 in U.S. Surely google are aware of this already. I would settle for BTC I guess.

All good points. But how many reCaptchas occur per day? Google could also use page hits to google as well. But this is parallel to my idea to use a separate captcha to mine BTC.  Let's call it caBTCha.

Will try to dig out some more info.

Likely not enough.  Lets say you gained 100% of the market and sustained a load of 100 million captchas per second.  Just to put that into perspective that is an average of almost 3000 captas per internet user per day.

If you could solve a double hash using only 50 math captchas (which I think is unrealistic) per double hash and with no error (100% user accuracy) you would make almost 2 cents per day.  That is before your cost of running a server network capable of generating 3000 captchas per person on the internet daily.

The reality is that a single hash is worth almost nothing.  

At current difficulty it takes (2^32)*1.3 million = 5.58E+15 hashes to form a block.  That puts the value (with current price & BTC reward) at 4.92526E-14 per hash.  

Another way to look at it is that it takes  203,034,817,629 (203 trillion) hashes to generate 1 penny of value.
