# CoinHive captcha for Yii2

This widget implements CoinHive proof-of-work captcha for your Yii2 web application.

From a website owner’s perspective the CoinHive captcha works exactly like a conventional captcha,

such as Google’s reCaptcha.

The captcha is embeded as a usual Yii2 widget for ActiveForm with any of your model.

User client side generates a token. The token is submitted together with the other form data.

Then bundled captcha validator confirms this token on your server through CoinHive 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.
