Moca Ads

Moca Ads - Hackathon Project Description

Project Title: Moca Ads - Privacy-Preserving Advertising Platform

Tagline: Users monetize their data, advertisers get authentic targeting

Problem Statement

Digital advertising is fundamentally broken. Users are extensively tracked by ad networks but receive zero compensation for their valuable data. Meanwhile, advertisers struggle with bot fraud and can't verify authentic user demographics. Centralized platforms like Google and Facebook capture 60%+ of ad revenue while users create the value. Privacy regulations are breaking traditional cookie-based advertising models, creating urgent need for new solutions.

Solution Overview

Moca Ads is a browser extension that creates a three-sided marketplace for privacy-preserving advertising. Users verify their demographics once through AIR Kit's zero-knowledge credentials, then earn MOCA tokens for viewing relevant ads. The extension automatically replaces existing ad spaces with targeted advertisements based on verified user credentials, without revealing any personal data.

Technical Architecture

Frontend: Browser extension built with React/TypeScript that detects common ad containers (Google AdSense, Facebook Ads) and replaces them with Moca Ads content.

Identity Layer: Deep integration with AIR Kit for zero-knowledge credential verification. Users prove demographic attributes (age brackets, geographic regions, income levels, education status) without revealing exact personal information.

Blockchain: Smart contracts deployed on Moca Chain handle campaign creation, budget management, and automatic reward distribution. Uses native MOCA tokens for all transactions.

Backend: Node.js service manages ad serving, campaign matching, and batch reward distribution. Operators can update user activity off-chain for gas efficiency.

Innovation & Impact

Moca Ads represents a paradigm shift from "surveillance capitalism" to "participation capitalism." By leveraging AIR Kit's zero-knowledge credentials, we enable verified demographic targeting without compromising user privacy. This addresses growing privacy concerns while creating new revenue streams for users and sustainable alternatives for publishers.

The platform showcases the power of decentralized identity infrastructure to solve real-world problems at scale. Users maintain complete control over their data while accessing new monetization opportunities.

Market Opportunity

The digital advertising market is at an inflection point due to cookie deprecation and privacy regulations. Our solution addresses a $600B market opportunity by providing privacy-compliant targeting that benefits all stakeholders. Early adoption in the Web3 community provides a strong foundation for mainstream expansion.

With 86% of users wanting control over their data monetization and growing advertiser demand for verified, authentic audiences, Moca Ads is positioned to capture significant market share in the evolving post-cookie advertising landscape.
