DocPat — Decentralized Medical Records

Blockchain-powered medical records platform with on-chain access control, IPFS storage, and end-to-end encryption.

DocPat is a decentralized medical records management system that eliminates centralized authentication in favor of on-chain access control via Solidity smart contracts. Medical documents are stored on IPFS using content-addressed identifiers (CIDs), ensuring tamper-proof and censorship-resistant storage. The platform provides role-based APIs for doctors, patients, and administrators, end-to-end encryption for all records, immediate access revocation capabilities, and a full on-chain audit trail. The system is designed for ML dataset readiness and regulatory compliance.
