Traditional digital advertising relies on massive data collection, where companies store and broker user information to target ads. This approach not only threatens user privacy but also creates risks of data breaches and unauthorized data sales.

Soveriegn Ads introduces a novel solution by leveraging Zero-Knowledge Proofs (ZKPs) to enable ad targeting without exposing personal data. Users’ data never leaves their devices, yet advertisers can still verify whether a user belongs to a target audience

•	Targeted Ads without Data Exposure: Advertisers can still reach the right audience without collecting user data.
•	User Data Sovereignty: Users retain complete control over their data, which never leaves their device.
•	Fair Compensation: Users are rewarded directly for ad interactions, aligning incentives between users and advertisers.
•	Seamless Integration: Ads are displayed directly on websites, ensuring a smooth experience for both users and businesses.

The project ensures privacy-preserving ad targeting using zero-knowledge proofs (ZKPs). It revolves around two key components: user data and ad criteria.

1.	Generating ZK Proofs:
•	Users create a ZK proof of their data using SP1 zkVM without revealing any private information.
•	The proof only verifies whether the user meets the advertiser’s criteria, without exposing raw data.
2.	Verifying Ad Criteria:
•	The generated ZK proof is checked against the ad criteria to determine if the user qualifies for the ad.
3.	Displaying Ads & Rewards:
•	If the user meets the ad criteria, the ad is shown.
•	As an incentive, users are rewarded in USDC for viewing relevant ads.

This approach ensures zero data leakage to big companies, allowing targeted ads while maintaining user privacy and data sovereignty.
