The Coinhive script mines Monero: https://coinhive.com/ https://coinhive.com/ . It's been a while since JavaScript Bitcoin mining was feasible :)

- brndnmtthws 9y agoThe unwashed masses can't understand the difference between different coins, so you might as well call everything Bitcoin.
- em3rgent0rdr 9y agoMost of these crypto currency exchange are derived from bitcoin's codebase (or at least from bitcoin's white paper) so from that perspective I don't consider calling these other crypto's as "bitcoin" to be incorrect, just not specific. I could imagine that maybe could use the distinction of capital Bitcoin to refer to the specific blockchain while lowercase bitcoin to refer to any Bitcoin forks.
- rileyphone 9y agoI really like the idea of this as a captcha alternative, especially with the "train our neural nets" approach google has been taking recently with them.
- zeusk 9y agoHow would coinhive work as a captcha alternative? There is no human involvement in mining, is there?
- diggan 9y agoNot saying it would be a good idea but something like "Please wait until your CPU have done enough amount of work before submitting this comment"
- misterdata 9y agoThis exists: https://github.com/pixelspark/webpow https://github.com/pixelspark/webpow
- discreditable 9y agoIt works as a rate-limiter in a way. If you're interested look into HashCash as proposed to combat email spam: https://en.m.wikipedia.org/wiki/Hashcash https://en.m.wikipedia.org/wiki/Hashcash
- zeusk 9y agorate-limiting is not what captcha does, that's for DDoS protection and even in that scenario I feel HashCash and crypto mining is a very terrible idea.
- discreditable 9y agoHence "captcha alternative" and not "alternative captcha".
- zeusk 9y agoWouldn't "captcha alternative" imply that the said alternative is a replacement for captcha and has similar functionality?
- discreditable 9y agoNot necessarily. If the goal is to reduce bot activity, captchas and hashcash are two ways to do that. Captchas are hard for bots to pass, whereas hashcash wastes a fixed amount of CPU time. The result is that robot operators have to invest more effort to abuse your service at scale than they're willing to (hopefully). In this sense, hashcash is a captcha alternative—it's not a captcha, but it helps with the same problem. An alternative captcha might be using something other than reCaptcha. At least, that's how I'd interpret it.
