Demo: Protected Form

This form is protected by PowForge CAPTCHA. Prove you're human.

Embed on Your Site

<script src="https://captcha.powforge.dev/widget.js"></script>
<div id="powforge-captcha"></div>

Add these two lines to your HTML. The widget handles PoW mining, Lightning skip, and returns a verification token your backend validates.

npm install @powforge/captcha | Source

How It Works

1. Visitor loads your page -- widget requests a PoW challenge
2. Browser mines a SHA-256 hash matching the difficulty target
3. Solution verified server-side, token issued
4. Your form submits the token, your backend validates it

No tracking. No cookies. No Google. Just proof of computational work -- the same mechanism that secures Bitcoin.
