GETKINETIK

1. The payload is re-serialized with the same stable JSON rule the app uses (keys sorted lexicographically, no whitespace). That byte sequence must equal message exactly — catches any edit to payload fields.
2. sha256(message) truncated to 16 hex chars must equal the embedded hash.
3. For Proof of Origin and earning artifacts, the attribution field must still read GETKINETIK by OutFromNothing LLC — it was signed as part of the message, so stripping it breaks verification.
4. Ed25519.verify(signature, message, payload.pubkey) must return true.

If all four checks pass, the device that owns the secret key matching payload.pubkey signed this exact artifact. The verifier does not call home, does not log, does not persist — once the page closes, nothing remains.

GETKINETIK is the independent bureau for the decentralized physical economy. Every node generates a hardware-backed Ed25519 identity that never leaves the device, signs a hash-chained uptime log, and earns a public Genesis Score — a 0–1000 grade partner networks can read before they pay verified-user premiums. Methodology is public and versioned.

The three artifact types this verifier recognizes:

• Signed heartbeat — a timestamped sensor snapshot chained to every previous beat. Proves the device was online, what it sensed, and in what order.
• Proof of Origin — a shareable QR-code artifact minted on demand. Contains the node's full sensor state plus its current Genesis Score, signed by its Ed25519 key. Paste the JSON here to verify, or POST the share URL to /api/verify-device.
• Signed earning — a receipt for a DePIN payout. Records the source network (e.g., Nodle, DIMO), the currency, gross amount, 1% bureau fee disclosed in the signature, and net — all signed in so none can be altered after the fact.

GETKINETIK sits outside every DePIN network it grades — no token, no equity in graded networks, no payment in any network's native asset. The bureau publishes the grade; partners decide what to do with it.
