Privacy Ads is a privacy-preserving advertising SDK designed to enable audience targeting and campaign optimization without compromising user confidentiality.

Instead of collecting and correlating user data across multiple sources, Privacy Ads uses encrypted data segmentation powered by ZK (Zero-Knowledge) proofs or Fully Homomorphic Encryption (FHE) via Zama or Fhenix. This allows advertisers to match relevant ads to users without ever exposing or sharing raw personal data.

For advertisers, this means they can still reach the right audience segments — e.g., “music lovers in São Paulo” — without gaining access to any identifiable information. For users, it means personalized ad experiences with zero data leakage.

To further enhance trust and transparency, Chainlink CCIP can be used to deliver verifiable proofs of audience targeting or ad spending between different chains, while Base or Arbitrum networks can handle rewards, tokenized incentives, or ad bidding logic.

In essence, Privacy Ads represents a new model for decentralized advertising — one that keeps the effectiveness of data-driven marketing while fully preserving user privacy and compliance.
