Proof Quickstart

Add decision evidence to your application in 3 steps.

Step 1: Install

Step 2: Record a Decision

Step 3: Approve and Seal


What Just Happened?

  1. Record — Your decision was captured with structured metadata (who, what, why, AI context)
  2. Chain — The event was linked to the previous event’s hash, forming an immutable SHA-256 chain
  3. Seal — Human approval triggered the final hash seal. The event is now tamper-proof.
  4. Export — The JSON-LD document contains everything an auditor needs: decision, approval, and chain integrity proof.
If anyone modifies event #N after sealing, the hash chain breaks at #N+1 — immediately detectable.
