About
The problem it solves RegenPass revolutionizes event attendance by providing verifiable, interactive POAPs using AI-driven booth recognition and seamless blockchain minting. It enhances engagement, reduces fraud, and makes event participation provable and rewarding. User Interaction and Data Flow 1. User arrives at an event and is geo-verified to ensure they are within the designated event zone. 2. The user scans a booth with their mobile camera. 3. The AI agent analyzes booth banners, determines the blockchain, and provides a minting transaction builder. 4. Augmented reality (AR) overlays interactive digital assets related to the event, enriching user engagement. 5. The user confirms minting, and the transaction is executed on the correct chain via CCIP. 6. The POAP is issued and displayed in the user’s wallet in real-time. 7. The user is added to a leaderboard standing, where lucky winners can receive exclusive event-specific perks. The project architecture and development process - Frontend: Mobile-first web interface with camera integration. - Backend: AI-powered booth recognition, geo-fencing, and event verification. - Smart Contracts: Deployed on Base Sepolia & Ethereum Sepolia, supporting both direct and cross-chain minting. - Cross-Chain Execution: Chainlink CCIP for seamless cross-chain POAP minting. Product Integrations - Chainlink CCIP: Enables cross-chain minting. - Geo-Location Services: Ensures attendees are within the event area before minting. - AI Image Processing: Booth recognition for automatic chain assignment. - Augmented Reality (AR): Enhances POAP collection with interactive overlays. - Block Explorers: Transaction tracking on Base and Ethereum Sepolia. - Leaderboard System: Tracks attendees who minted POAPs, allowing event organizers to reward top participants with perks. - Chainlink VRF: Ensures fair and tamper-proof random selection of winners for event-based rewards. Key differentiators and uniqueness of the project - AI-powered booth recognition: Automates blockchain selection for minting. - Seamless AR integration: Enhances the POAP collection experience with interactive visuals. - Geo-fencing verification: Ensures only attendees in designated areas can mint POAPs. - Cross-chain POAPs: No manual selection; CCIP routes transactions automatically. - Real-time minting confirmation: Users get immediate POAP verification. - Leaderboard standing & event perks: Adds gamification, rewarding users who engage the most. Trade-offs and shortcuts while building - AI Optimization: Initial AI model is basic; future updates will improve accuracy. - CCIP Simulation: Testing utilized CCIPLocalSimulatorFork before mainnet deployment. - Mobile-first Approach: Desktop UI is secondary and will be optimized post-launch. Additional Features During the BUIDLathon, we: - Enhanced the AI agent to suggest optimized gas fees for transactions. - Enabled support for direct minting beyond Arbitrum Sepolia. - Implemented on-chain storage of event metadata for transparency. - Added geo-fencing validation to restrict POAP minting to event attendees. - Integrated AR overlays to provide a dynamic and engaging experience. - Introduced a leaderboard system where POAP minters can qualify for event-specific rewards and perks.
