Verification platform

Managed decision flow

Requests move through validation, rate limits, signals, risk, policy, and a bounded decision outcome.

  • Allow
  • Proof of work
  • Interactive challenge or block

Verification platform

Adaptive proof of work

SHA-256 work is verified on the server with difficulty bounded by policy, device class, risk, and recent service load.

  • Worker-based execution
  • Server verification
  • Difficulty bounds

Verification platform

Explicit fallbacks

Missing risk configuration follows a site-owned fallback policy instead of silently allowing a request.

  • Fail-safe defaults
  • Origin binding
  • Complete callback states
