Decentralized neural data consent platform for Kenya — encrypt brain data on Filecoin, grant/revoke researcher access via Lit Protocol, get SMS alerts via Africa's Talking. Built for PL Genesis Hackathon 2026. # CortexVault Kenya > **Decentralized neural data consent for community health research in Kenya.** A patient-facing consent wallet where users store encrypted biosignal data on Filecoin, grant and revoke researcher access via Lit Protocol's programmable conditions, and receive SMS notifications when their data is accessed — mobile-first, bilingual (English / Swahili). Built for the **PL Genesis Hackathon 2026** — Cognitive Sovereignty & Neural Data Rights track. **Live Link →** **Watch Demo** github.com --- ## How It Works ### Patient flow 1. Connect with a wallet address (or use demo mode) 2. Upload an EEG session — encrypted with Lit Protocol, stored on Storacha/Filecoin 3. Grant a researcher access: set their name, purpose, and an expiry date 4. View the full audit log of every access event 5. Revoke access at any time — the researcher is blocked immediately 6. Receive an SMS: *"Dr. Odhiambo accessed your brain data on March 30"* ### Researcher flow 1. Connect with a wallet address 2. See all datasets patients have granted access to 3. Click to decrypt and view (Lit Protocol checks conditions on-chain) 4. After revocation, decryption fails with *"Access revoked by data owner"* --- ## Tech Stack | Layer | Tool | |---|---| | Frontend | Next.js 14 + Tailwind CSS + shadcn/ui | | Storage | Storacha (`@web3-storage/w3up-client`) | | Access control | Lit Protocol v8 SDK | | SMS notifications | Africa's Talking API | | Demo data | PhysioNet EEG Motor Movement dataset | | Deployment | Vercel | --- ## Project Structure ``` app/ ├── page.tsx # Landing / language selector ├── patient/ │ ├── page.tsx # Patient dashboard (consents, audit log, ethics) │ └── upload/page.tsx # EEG upload flow ├── researcher/ │ └── page.tsx # Researcher portal └── api/ ├── upload/route.ts # Storacha upload handler ├── grant/route.ts # Lit Pro …
