OYD Protocol

OYD Protocol addresses a fundamental problem in the digital economy: users generate valuable personal data but receive nothing while platforms profit billions from it. Our core idea came from realizing that users should be able to monetize their own data directly. When you browse Amazon, shop on Flipkart, or order from Zomato, these platforms extract massive value from your behavior patterns, preferences, and interactions - but users see none of that revenue. We built the first platform that lets users actually get paid when companies access their data. Here's how it works: Users interact with our mock e-commerce platform where they can see the real-time value of data being collected about them. They can choose to consent and get paid for it. The technical flow: Users get verified through Self Protocol (preventing fake accounts and bots), their data gets authenticated using Reclaim Protocol's zkTLS proofs to ensure it's legitimate, then stored and tokenized through Lighthouse's DataDAO. Companies can purchase access to this verified data, and users receive instant payments via PYUSD. The result is a transparent data economy where users finally profit from their digital footprint, companies get high-quality verified data instead of bot traffic, and data buyers get authentic insights from real humans. India's new DPDP Act provides the perfect regulatory tailwind - companies now face heavy fines for misusing data and must implement proper consent mechanisms. Our platform helps companies stay compliant while creating a new revenue stream for users. With 500 million Indian internet users, we're creating the infrastructure for the world's largest data monetization platform.

OYD Protocol is a multi-chain application integrating four blockchain protocols to create a robust data monetization pipeline. Our frontend, a mock e-commerce platform built with React and Next.js, tracks user interactions (browsing, purchases, searches) and displays real-time data value popups. Users can consent to monetize their data with one click, triggering our verification and payment system. For identity verification, we deployed contracts on Celo mainnet using Self Protocol's SDK, integrating Aadhaar for the Indian market to generate zero-knowledge proofs for privacy and sybil resistance, ensuring only real humans participate and preventing bot-generated fake data in our marketplace. Our core DataDAO smart contracts, hosted on Base and Polygon via Lighthouse's SDK, manage data tokenization, subscription tiers for data buyers, and store encrypted IPFS hashes on-chain. Verified user data is encrypted, stored permanently on Filecoin, and minted as DataCoins representing ownership of data packages, with smart contracts controlling access for paying subscribers. Payment processing runs on Ethereum, where DataCoins are converted to instant payments for users when companies purchase data access, integrating seamlessly with existing payment systems. Off-chain, Reclaim Protocol's zkTLS proofs cryptographically verify data authenticity without exposing personal information, ensuring buyers receive legitimate human insights. The technical challenge was orchestrating multi-chain interactions, achieved through a custom event system syncing data flow between Celo (identity verification), Base (data storage), and Ethereum (payments). When a user is verified on Celo, it triggers data tokenization on Base and prepares payment contracts on Ethereum. Designed for emerging markets, our platform leverages India’s DPDP Act for regulatory support, but its core concept is globally applicable, enabling users worldwide to profit from their data.
