Why Your AI Agent Needs Cryptographic Proof

AI agents are making decisions, signing contracts, calling APIs, moving money. But here’s the problem: nobody can prove what actually happened.

When an autonomous agent executes a transaction, there’s no audit trail that can’t be tampered with. Logs can be edited. Timestamps can be faked. If something goes wrong — and it will — you’re left arguing over whose logs are correct.

What ArkForge Trust Layer Does

Trust Layer is a lightweight API that creates cryptographic proof for any AI agent action. Every proof includes:

• SHA‑256 hash of the payload — tamper‑evident by design
• Three independent witnesses — Ed25519 signature, RFC 3161 timestamp, and Sigstore Rekor transparency log
• A unique proof ID — retrievable and verifiable at any time

One API call. Three witnesses. Immutable record.

How It Works

Your agent sends a POST request with the action payload:

curl -X POST https://your-endpoint/v1/prove \
  -H "Authorization: Bearer YOUR_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"action": "transfer", "amount": 500, "to": "vendor-42"}'

You get back a signed proof with all three witness attestations. Store it, share it, or verify it later — the cryptographic chain speaks for itself.

Why It Matters Now

The EU AI Act requires traceability for high‑risk AI systems. Regulators are catching up. Clients are asking questions. “Trust me” doesn’t scale.

Cryptographic proof does.
