FHIR-based Web3 healthcare with AI-driven, patient-owned records & family risk analysis
Demo
About
MediChain.AI is a Web3-powered, AI-driven healthcare platform where patients truly own and control their medical records. By combining blockchain, AI, and decentralized storage, it ensures transparency, immutability, and patient-controlled access. Blockchain Layer (Polygon): Stores metadata and consent logs for secure, verifiable access. Off-Chain Storage: Encrypted health records stored in IPFS/Filecoin + MongoDB. AI Engine: Provides prescription interpretation, medication summaries, and genetic risk detection across generations. Family Health Graph: Enables intergenerational linkage of health data to identify hereditary risks. FHIR Format (WHO Standard): Ensures interoperability across hospitals, labs, and digital platforms worldwide.
How it's made
We built MediChain.AI with a layered architecture combining Web3, AI, and decentralized storage: Frontend: Browser-based interface for patients/doctors, wallet integration (MetaMask Snap). Backend: Node.js + Express server managing off-chain storage, authentication, and AI service orchestration. Blockchain (Polygon): For consent logs, metadata storage, and immutable access trails. Storage: IPFS/Filecoin for encrypted records, MongoDB for fast indexing and retrieval. AI Engine: Python microservices that summarize medical reports and perform genetic risk analysis. Notifications: Real-time alerts for record access requests and approvals. User Onbaording: Using Self protocol via Aadhar based authentication for Authenticity. Graph Optimization: Integrated The Graph for efficient data queries and visualization of family health linkage.
