Why PaywallProject uses Prosopo instead of Google reCAPTCHA or Cloudflare Turnstile

At PaywallProject, we prioritize security, user experience, cost-effectiveness, and data privacy when selecting CAPTCHA solutions. Instead of using Google reCAPTCHA or Cloudflare Turnstile (which are often bypassed at scale by bots), we’ve chosen Prosopo (Procaptcha) for our bot protection. Here’s why:

1. Effortless Integration

Prosopo is a drop-in replacement for reCAPTCHA and hCaptcha, making setup simple and fast. This allows us to seamlessly integrate bot protection without complex implementation.

2. Unique Proof-of-Work (PoW) Security

One of the standout features of Prosopo is its Proof-of-Work (PoW) CAPTCHA technology. Unlike traditional CAPTCHAs that rely on image recognition (e.g., selecting traffic lights or clicking objects), PoW CAPTCHAs challenge users with computational tasks. This approach provides several advantages:

• Bot Mitigation Through Computation – Instead of asking users to complete visual puzzles, PoW CAPTCHAs require a small, device-generated computation to prove legitimacy. Bots attempting mass interactions quickly become resource-exhausted, making large-scale automation infeasible.
• Asymmetry in Effort – Solving a PoW CAPTCHA takes noticeable effort for a bot but remains seamless for legitimate users. Unlike Google reCAPTCHA, which often subjects users to frustrating verification loops, Prosopo ensures a smoother experience.
• Adaptive Challenge Scaling – The difficulty of the PoW task can be dynamically adjusted based on user behavior, traffic conditions, or risk factors, ensuring optimal protection without unnecessary friction for real users.

3. Tailored Bot Defense

Unlike traditional CAPTCHAs, Prosopo allows us to customize our bot protection strategy, adjusting challenges in real-time based on risk levels. This ensures the right balance between security and usability.

4. Improved User Experience

Prosopo eliminates frustrating image-based CAPTCHAs (like traffic lights or buses). Instead, users face minimal disruptions, leading to higher engagement and reduced bounce rates. Since PoW challenges run in the background, users often don’t even notice them.

5. Customizable Difficulty Levels

We can fine-tune CAPTCHA difficulty based on risk assessment:

• Stronger challenges for sensitive areas (e.g., login, payment pages).
• Easier challenges for low-risk areas, improving user experience.

6. Data Privacy & Compliance

Privacy is a priority for PaywallProject. Prosopo:

• Does not track or sell user data (unlike Google reCAPTCHA).
• Minimizes data collection and avoids centralized storage, ensuring compliance with privacy regulations.

Conclusion

By using Prosopo, PaywallProject benefits from stronger bot protection, improved user experience, lower costs, and enhanced privacy compared to Google reCAPTCHA or Cloudflare Turnstile. Our choice ensures a more secure, user-friendly, and cost-effective approach to CAPTCHA challenges.
