Placeholder is an On-Chain Attestation Reputation System designed to bring honesty, safety, and transparency to the world of online advertising.
In the old days, verifying the integrity of online ads was extremely difficult:
- No Accountability: Publishers could run malicious ads without consequence.
- Unsafe Experiences: Ads containing malware, scams, or inappropriate content could appear just about anywhere.
- Untrustworthy Ecosystem: Advertisers and publishers had little incentive to maintain high-quality standards.
Built on top of the TrueNetwork Attestation Layer, Placeholder empowers users—that means you—to have a direct say in what ads and publishers earn your trust.
- Community Votes: You cast verifiable, on-chain votes rating the quality and trustworthiness of both advertisers and publishers.
- Reputation Score Generation: A cutting-edge Reputation Algorithm blends your votes with on-chain activity data to produce a dynamic, tamper-resistant Reputation Score.
- Enforcement of Quality: Ads and publishers with low Reputation Scores lose their placements, ensuring that only the most honest, reliable content gets through.
