Bitcoin Forum

Bitcoin is a revolutionary digital cryptocurrency. It has all the properties of a good currency. It is scarce, divisible, portable and durable. However, a common criticism is that it is not a commodity as it does not satisfy any direct desires. However, because Bitcoin is a proof-of-work system, it is possible to turn BTC into a commodity by using it as replacement for visual and audio CAPTCHA's.

I'm not sure how many people are interested this. The goal is flexible so whatever is raised will be put towards at least obtaining a domain and working on development. I'm a certified PHP developer (proof (http://www.zend.com/en/store/education/certification/authenticate.php/ClientCandidateID/ZEND015302/RegistrationID/238093320)), so I will be able to handle the development by myself if funding the project doesn't pan out but I'd like to be able to hire some other developers to make things less stressful and speed things up.

That part right there... Spammers already pay for captcha bypassing, so your system will only make their life easier and probably less expensive, because if you wish to make it more expensive for spammers, it will be too expensive for valid users.

But anyway, good luck with your project. I'm curious to see the result and if it will work.

Thanks for the feedback.

I agree with you that the price for getting into a website has to be more than the price it takes for a spammer to get a CAPTCHA solved otherwise we're just making things easier for them. One way to deal with that would be to allow feedback from websites. If after a certain number of days you aren't reported as a spammer, you get a refund of your tokens and can use them again. Whereas spammers would be forced to buy more tokens. That would allow the price to remain high enough to cripple spammers but not inconvenience valid users as much. Also, it would put spammers' resources into Bitcoin mining, strengthening the network even more, instead of putting it towards having low paid workers solve A/V CAPTCHA's. We could also have reputations tied to tokens as well. As you spend tokens and aren't reported as a spammer, you aren't charged as much for new tokens. If you suddenly start spamming, the price goes back up to normal.

Im interested in this.

Yeah, your dream come true ;)
Was going to post the link to this thread on the other one, now i don't need cause you already found it lol

I have a different idea how to prove you arent a spammer across multiple sites. Im trying to get it implemented on a new site Im getting developed.

haha not really. If you arent spammin gone site what is the chance you will spam another ?

Oh... Even spammers use some sites personally. I know of some forums who are full of spammers and yet they don't spam those forums ;D

Well, no takers so far. I'm thinking there isn't much demand for this after all. That's fine. I've also reconsidered my argument for BTC being a commodity without this service in existence. Since Bitcoin is a proof-of-work system, if you desire to show proof-of-work, BTC will directly satisfy that need whether or not there is a CAPTCHA replacement service. Thanks for reading.
