A New Way to Keep Ads Honest Placeholder is an On-Chain Attestation Reputation System designed to bring honesty, safety, and transparency to the world of online advertising. The Problem with Traditional 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. Introducing Placeholder 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. How It Works 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. How Can You Use Placeholder? Publish Ads (No Gas): With Coinbase’s platform, anyone can publish on-chain ads without gas fees, lowering barriers and encouraging new participants. This is instantly displayed on our digital billboard powered by a raspberry pi and display. Rate Ads: Use our Flutter app to rate ads. Your signed input goes to TrueNetwork’s Attestation Layer, applying Quadratic Voting principles to yield a fair Reputation Score. Community Power: Your collective ratings filter out malicious ads, ensuring a safer, more transparent ecosystem. Placeholder lets users—not corporations—shape advertising standards.
