AuPass — Proof of Provenance for Gold | Offline edge AI + live P2P delegated inference (QVAC)

AuPass turns a photo of a real gold mining document into a tamper-evident, publicly verifiable provenance passport — running entirely on-device, no cloud.

It's the trust layer that real-world-asset tokenization is missing: provenance first, token second.

Built for the QVAC Hackathon I – Unleash edge AI (DoraHacks), on Tether's QVAC edge-AI SDK.

— Everything in this video is the REAL site, driven live — including the verifier and a real peer-to-peer inference. —

How it works
🔍 Offline OCR reads the document (QVAC ONNX) — no internet needed.
🧠 A local LLM (Qwen3 4B) structures the data — on the device.
✅ Deterministic, auditable rules verify it — license validity dates, the ANM process number, and a real CNPJ/CPF check-digit validation. The AI reads;
explainable code judges.
🔏 A SHA-256 seal makes it tamper-evident — change a single character and the seal breaks. The seal also commits to the verification verdict, so a "valid"
stamp can't be moved onto altered data.
🌐 Anyone can re-check the seal client-side in the browser (Web Crypto) — no server, no trust required.
🛰️ When a device is weak, the heavy model can be delegated to a peer over end-to-end-encrypted P2P (QVAC / Holepunch) — no server, no cloud — while OCR,
verification and the seal stay local. The answer in the demo comes straight from the peer's GPU, live.

Why edge AI
The gold supply chain runs through places with no reliable internet — the pit, the road, the collection point — and handles sensitive paperwork that
shouldn't leave the device. Cloud AI isn't an option there. AuPass solves it on the edge, and the sealed passport becomes the provenance backing that lends
credibility to any future tokenization.
