Zero-Knowledge Proofs (ZKPs)

ZKPs are the secret ingredient that makes AdPriva private, verifiable and fraud-proof.

With Zero-Knowledge Proofs, every engagement can be mathematically proven without ever exposing user data.

What Are ZKPs?

Zero-Knowledge Proofs let one party (the prover) demonstrate something is true to another party (the verifier) without revealing the underlying data.

In AdPriva:

  • Users → Prove they viewed, clicked or converted without revealing identity.
  • Advertisers → Receive cryptographic evidence, not raw data.
  • Publishers → Get proof-backed revenue, with fewer disputes.
  • Auditors & Regulators → Verify campaign claims via anchored proofs.

How AdPriva Uses ZKPs

  • Consent Proofs → Verifies that the user explicitly opted into a category.
  • Engagement Proofs → Validates that a view, click or conversion met human checks.
  • Bounded-Use Proofs → Ensures ads were shown only within user-approved categories.
  • Batch Verification → Groups proofs together, enabling scale and efficiency.

ZKP Flow

  1. Engagement → User views, clicks or converts.
  2. Proof Created → Signed cryptographic receipt generated.
  3. Proof Verified → Engagement validated with zero-knowledge methods.
  4. Proof Anchored → Logged in AdPriva Explorer (batch ZKP + on-chain).
  5. Settlement → Advertiser billed → Publisher and User rewarded in stablecoins.

Why ZKPs Matter

  • Privacy-first → No personal data leaves the device.
  • Fraud resistance → Bots and replay attacks can’t forge valid ZKPs.
  • Transparency → Every interaction leaves a verifiable trail.
  • Scalability → Batch proofs validate millions of events efficiently.
  • Compliance → Meets GDPR, ePrivacy, CCPA and FTC substantiation requirements.

With ZKPs, AdPriva replaces “trust me” metrics with mathematically guaranteed truth protecting users, empowering publishers and giving advertisers compliance-ready confidence.
