Technical Architecture
HealthChain is a decentralized, interoperable healthcare data management system using a modified version of the PBFT consensus mechanism designed for HIPAA compliance and zero-knowledge data sharing.
Secure Data Storage
- End-to-end encryption with AES-256-GCM
- Zero-knowledge proofs for authorization
- Distributed IPFS storage with Merkle DAGs
Interoperability
Core Components
Smart Contracts
Solidity-based contracts implement HIPAA-compliant access control with ZK-SNARKs for private data sharing without revealing patient identities.
Identity System
Decentralized identifiers (DIDs) with reusable credentials for patients, providers, and researchers.
API Endpoints
RESTful and GraphQL APIs for EHR integration with JWT-based authentication and role-based access control.
