Proof of Eligibility

Problem Statement

Proof of Eligibility is a revolutionary decentralized identity system focused on transforming clinical trial eligibility verification - one of the most critical and privacy-sensitive use cases in healthcare. By combining the power of Decentralized Web Nodes (DWN), Filecoin storage, Oasis privacy features, and LIT Protocol encryption, we create a comprehensive solution that enables secure, privacy-preserving eligibility verification for clinical trials while maintaining patient sovereignty over their medical data.

Solution

Built with Next.js frontend and custom DWN server implementing W3C VC standards. Used @web5/dids for cryptographic DID generation and @tbd54566975/dwn-sdk-js for decentralized data storage.Created innovative Filecoin plugin architecture for automatic credential backup, any DWN deployment can now easily add Filecoin storage.Integrated Oasis Network for privacy-preserving verification using ParaTimes and zk-SNARKs for HIPAA compliance.Implemented LIT Protocol for granular access control with programmable encryption conditions.The hacky part: solved Turbopack CDN import issues enabling browser-only VC generation without build errors. All components communicate via JSON-RPC protocol, creating a truly decentralized clinical trial eligibility system where patients control their medical data while enabling instant verification for research institutions.Key technical innovations:Filecoin plugin architecture enabling massive adoptionBrowser-only DID/VC generation avoiding native build errorsMulti-layer privacy stack with Oasis + LIT encryptionHIPAA/GDPR-compliant clinical trial verification
