Onchain blood donation And emergency alert system

Demo

About

The problem it solves 📌 Problem It Solves In emergency medical situations, finding a nearby blood donor quickly is often difficult and unorganized. This platform connects blood donors and recipients instantly through a transparent, decentralized system. It ensures faster communication, builds trust with verifiable donor data, and provides emergency alerts — making the life-saving process quicker, safer, and more reliable. People can use it to: Register as blood donors. Send emergency alerts when blood is urgently needed. Find nearby verified donors. Maintain transparent, tamper-proof donor records using onchain technology.

How it's made

Challenges we ran into 📌 Challenges I Faced While building this project, I encountered a few key challenges: Integrating JavaScript functionalities smoothly across multiple pages like registration, dashboard, and emergency alert. Ensuring real-time updates in the donor list and emergency alerts without backend databases. Designing a professional and emotionally engaging UI with limited resources. Managing time efficiently as this was my first hackathon project, alongside regular studies and responsibilities. 📌 How I Overcame Them I carefully divided the project into small, manageable tasks. Took guidance, debugged JavaScript functionalities, and made sure alerts and messages displayed correctly. Focused on clean, consistent UI designs using CSS and meaningful visuals. Prioritized essential features first and then added enhancements step by step. This experience helped me learn better time management, problem-solving, and improved my confidence in front-end and blockchain-integrated applications.
