What is IronWall?

IronWall is a privacy-first, client-side Proof-of-Work (PoW) security protocol. It serves as an invisible alternative to reCAPTCHA.

Instead of challenging the user with image puzzles (identifying traffic lights), IronWall challenges the device's computational power. It forces the browser to solve a cryptographic puzzle (Argon2) in the background before a request is allowed.

Key Features:

  1. Zero Friction: No UI, no clicking, invisible verification.
  2. Privacy: No cookies, no tracking, GDPR compliant.
  3. Lightweight: 3KB SDK size.
  4. Bot Deterrence: Makes high-volume attacks economically unviable by consuming CPU/RAM.
