Lifeline+: AI Donor Prediction & Blockchain Blood Tracking

Inspiration

Thalassemia patients require frequent blood transfusions, but finding compatible donors quickly is often a life-threatening challenge. Manual donor searches cause delays, while lack of transparency in blood tracking and NGO funding reduces trust. We were inspired to build Lifeline+, a platform that leverages AI for predictive donor matching and Blockchain for transparent blood tracking, to provide a faster, safer, and smarter solution for Blood Warriors and patients.

What it does

AI Donor Prediction: Predicts donor availability based on donation patterns, last donation date, and geolocation. Real-Time Donor Alerts: Sends instant notifications to nearby compatible donors. Blockchain Blood Tracking (BloodChain): Records each blood unit donation and transfusion securely and transparently. AI Virtual Health Assistant: Provides reminders for transfusion schedules, medication, and connects patients to telemedicine support. NGO Fund Transparency: Tracks donations via Blockchain smart contracts to ensure clear and trustable fund usage.

How we built it

AI/ML: Built donor prediction using Python (Scikit-learn) with time-series modeling. Blockchain: Implemented mock smart contracts using Hyperledger Fabric for immutable blood tracking. Frontend: Developed patient/donor app in Flutter and NGO/hospital dashboard in React.js. Backend: Node.js with MongoDB for data management. APIs: Integrated mock APIs for e-RaktKosh and Blood Warriors' Blood Bridge. P(donor_availability)=f(last donation date,donation frequency,geolocation proximity)

Challenges we ran into

Integrating AI donor prediction with real-time notifications in limited hackathon time. Simulating Blockchain ledger for blood tracking with realistic data. Ensuring HIPAA/GDPR-compliant secure data handling. Lack of access to real-world hospital APIs for testing live scenarios.

Accomplishments that we're proud of

Built a working MVP that predicts donors and sends alerts within seconds. Successfully demonstrated Blockchain-based blood tracking for transparent donations. Designed a telemedicine-ready interface with AI reminders for Thalassemia patients. Created an end-to-end prototype that aligns with Blood Warriors’ mission.

What we learned

How to integrate AI donor prediction with healthcare use cases. Blockchain's potential for transparent and secure medical tracking. The importance of UI/UX in critical healthcare apps for patients and NGOs. Real-world constraints in healthcare data sharing and compliance.

What's next for Lifeline+: AI Donor Prediction & Blockchain Blood Tracking

Integrate with e-RaktKosh and hospital systems for live blood inventory data. Launch full Blockchain-powered BloodChain for verified tracking. Add multi-language support for rural outreach. Partner with NGOs and government bodies for real-world pilot deployment. Expand to AI-powered genetic screening to help reduce new Thalassemia cases.
