Replace CAPTCHA with Proof-of-Work

In plain words

Replace CAPTCHA with Proof-of-Work is a security solution launched in 2014 that offers an alternative to traditional CAPTCHA verification. Instead of solving puzzles or identifying images, users complete computational proof-of-work tasks to verify they are human. The system is designed for website owners and developers who want to implement bot protection without the friction of standard CAPTCHA challenges. This approach combines security verification with a computational requirement that makes automated attacks more expensive to execute.

  Replace CAPTCHAs with WebAuthn passkeys for bot prevention2024 · github.com · ▲71

  I built Nocaptcha after getting frustrated with traditional CAPTCHAs both as a user and developer. WebAuthn passkeys offered a promising alternative that's both more secure and user-friendly. What makes Nocaptcha different: - Uses WebAuthn standard instead of puzzle-solving - No need for users to remember passwords or solve puzzles - Open source Current limitation: Working with W3C WebAuthn Community Group on true passkey disposal for this use case. Looking for feedback particularly on: 1. Integration experience 2. User experience compared to traditional CAPTCHAs
