Verification Primitive
Proof of Impression
A cryptographic receipt model for ad delivery that prioritizes auditability and trust.
Proof of Impression is Panorama's mechanism for turning ad delivery into a verifiable event, not a private dashboard claim. Instead of relying on opaque counters, the protocol links each meaningful step in the ad flow to a traceable pipeline state.
In simple terms: an impression is captured, checked, and only then considered eligible for payout logic. This creates clearer trust boundaries for advertisers, publishers, creators, and data providers.
Workflow
- 1) Capture: Publisher surfaces emit signed impression events through the SDK with campaign and placement context.
- 2) Correlate: Each event is stamped with a correlation ID so it can be traced across ingestion, proofing, and settlement.
- 3) Prove: The proof service generates cryptographic artifacts that attest the event passed required checks.
- 4) Verify: Verifier services validate proof integrity before the event can influence payout or attribution state.
- 5) Settle: Only verified outcomes move into settlement intents and downstream optimization logic.
What it protects against
- Unverifiable delivery claims that cannot be independently inspected.
- Broken attribution chains where events cannot be tracked end-to-end.
- Settlement actions triggered from low-confidence or unverified events.
- Manual reconciliation overhead caused by fragmented reporting systems.
Why it matters
The practical value is operational clarity: campaign stakeholders can inspect how an event moved from ingestion to verification and settlement intent. This supports better fraud resistance, cleaner optimization inputs, and more transparent payout logic.
How this relates to the rest of Panorama
Proof of Impression sits at the center of the marketplace, protocol status, and dCommerce narratives. It is the connective layer between event capture, verifier confidence, and programmable settlement outcomes.
