Natural disasters often reveal systemic issues in humanitarian aid, including:
- 🕒 Delays in fund release and aid delivery
- 💸 Corruption and misallocation of resources
- ❌ Lack of transparency and accountability
- 🧾 Inefficient tracking of aid and donations
BlockAid aims to revolutionize disaster relief using decentralized, transparent, and secure blockchain technology.
BlockAid is a decentralized platform leveraging blockchain, smart contracts, Web3 authentication, and IoT-based real-time tracking to make disaster relief:
- Transparent 🔍
- Efficient ⚡
- Tamper-proof 🔐
- User-verified 📲
- Immutable Recordkeeping using Hyperledger Fabric / Polygon
- Smart Contracts for automated fund release
- Web3Auth for secure wallet & social login
- Transak Integration for fiat-to-crypto donations
- IoT Integration for real-time aid tracking
- Beneficiary Feedback via mobile/web apps
- Polygon Smart Contracts for donation verification
- Lovable AI for decision logic & interactivity
- Supabase backend for scalable user data
