EncryptHealth is a privacy-first decentralized health data consent and analytics system developed under Future Systems Lab.
It integrates blockchain, FHIR/HL7 interoperability, and DAO governance to create transparent, reward-based data exchange between patients, practitioners, and research organizations.
| Module | Description | Demo |
|---|---|---|
| Frontend Dashboard | MetaMask user login, practitioner login, and consent toggle linked to the EncryptHealthToken smart contract. |  |
| Practitioner Login (View 1) | Practitioner interface for session access. |  |
| Practitioner Login (View 2) | Confirmed practitioner authentication state. |  |
| FHIR/HL7 Adapter | Parses mock FHIR `Patient.json`, verifies structure, and hashes identifiers for secure reference linkage. |  |
| Analytics Module | Displays consent history, token rewards, and basic performance summaries. |  |
- Frontend: Next.js + Tailwind (SSR enabled)
- Wallet Integration: Wagmi / Viem (MetaMask connection)
- Blockchain Layer: ERC-20 (EncryptHealthToken) on Sepolia
- Data Adapter: FHIR/HL7 mock parser for interoperability
- Analytics Layer: Local visualization of consent + token data
- Governance Layer (Phase 2): DAO linkage through token minting
- Extensibility (Phase 3): Optional on-chain registry and audit trail
✅ Architecture Flow: User → Consent Toggle → FHIR Adapter → EncryptHealthToken → Analytics Summary → DAO Governance (Phase 2 complete)

EncryptHealthToken (ERC-20)
Network: Sepolia
Address: 0xC11F23eC3A64FBA5C47b3F3d5D2a3B987A7bE4b7
Functions:
- balanceOf(address) — retrieves user balance
- mint(address,uint256) — mints reward tokens upon consent grant
Each consent action in the dashboard triggers an on-chain mint for compliant activity tracking.
| Layer | Technology | Function |
|---|---|---|
| UI / SSR | Next.js 14 + Tailwind | App rendering & routing |
| State / Query | React Query | Client-side data caching |
| Wallets | Wagmi v2 + MetaMask | Auth & EIP-1193 provider |
| Blockchain | Viem | Contract reads & writes |
| Standards | HL7 FHIR R4 | Healthcare data structure |
| Security | SHA-256 Hashing | Patient ID pseudonymization |
- ✅ Phase 1 — EncryptHealth MVP complete (functional consent, FHIR adapter, analytics, DAO link)
- ⬜ Phase 2 — Commercial expansion / integration layer (branding, partner onboarding, real FHIR data)
- ⬜ Phase 3 — Decentralized consent registry + on-chain audit trail
- On-chain consent registry storing hashed consents
- ConsentUpdated event logging for verifiable audit trails
- Integration with DID/VC credential flows (OIDC4VP)
- Direct interoperability with external FHIR APIs
- Replace patient.json with a live FHIR API
- Extend the consent toggle to map to organization-specific permissions
- Plug in existing ERC-20 or NFT-based incentive tokens
- Optional DAO layer for governance and access control
This phase activates once external wellness or healthcare partners connect live datasets and user wallets.
| Project | Focus | Status |
|---|---|---|
| HypnoNeuro | Gamified mental wellness + DAO ecosystem with non-PHI credential flows | ✅ MVP Complete |
| Secure Health Login | Wallet-based FHIR login portal (Next.js + Wagmi) | ✅ Operational |
| Future Systems Lab Core | Framework for building modular digital-health systems and components | 🟢 Active |
- HL7 FHIR R4 data format
- EIP-712 typed messages for structured wallet signing
- EIP-4337 (Account Abstraction) planned
- OIDC4VP + DID Consent Models planned
