Trust and safety
Evidence people can inspect.
GroundTruth is an early pilot product. Verification reduces obvious mismatch and replay risk; it does not turn a field observation into a licensed inspection or an infallible statement of fact.
What is checked
- • Required evidence and structured answers
- • One-time freshness challenge
- • File integrity and duplicate screening
- • Browser-reported distance from the target
- • Semantic match between evidence and brief
What is not guaranteed
- • GPS cannot by itself defeat a compromised device
- • AI verification can be uncertain or incorrect
- • Observations can change after capture
- • Operators are not licensed inspectors by default
- • Testnet settlement is not production payment history
Privacy by default
Exact worker coordinates are stored with a submission for distance verification but redacted from public task and receipt views. Public receipts show only the location verdict, reported accuracy, and capture time.
Campaign buyers should request only evidence needed for the stated business purpose. Faces, license plates, payment details, private addresses, and bystanders should be excluded or redacted whenever possible.
Evidence is stored in a private bucket and accessed through expiring signed URLs. Pilot customers must define an evidence-retention period before production use.
Prohibited tasks
Disputes and human review
Confident mismatches are rejected. If the verification service is unavailable or the result is uncertain, location-bound photo tasks are held for human review instead of being automatically paid. Pilot disputes should preserve the original files, verification checks, timestamps, and settlement record for manual resolution.
