CoinHive Captcha
Compatible XF Versions:
CURL
From a website owner's perspective the Coinhive captcha works exactly like a conventional captcha, such as Google's reCaptcha.
The captcha is embeded in an HTML form, runs client side in the user's browser and generates a token. The token is submitted together with the other form data. You can then validate this token on your server through our HTTP API.
Unlike with a conventional captcha however, the user does not have to “proof they're human”. Instead, the captcha is a “proof of work” – making it uneconomic for spammers to game your system.
