HealthProof is a decentralized smart contract built on the Celo blockchain to securely store and verify patient medical reports using cryptographic hashes.
It ensures that patient data remains tamper-proof, transparent, and accessible only by authorized entities such as hospitals or administrators.
In traditional healthcare systems, medical reports are often stored on centralized databases that are vulnerable to tampering, loss, or unauthorized access.
HealthProof addresses this problem by leveraging blockchain technology to ensure data integrity, privacy, and verification of medical records.
Each medical report is stored off-chain (e.g., on IPFS or cloud) and only its cryptographic hash is saved on the blockchain.
This allows for verification without exposing sensitive data on the public ledger.
- Allows hospitals or authorized admins to store and update patient medical report metadata on-chain.
- Enables anyone (patients, doctors, or auditors) to verify the authenticity of a medical report using its hash.
- Provides transparent access to report details without compromising patient privacy.
✅ Decentralized Storage Reference – Stores only the hash of reports (IPFS, cloud, etc.) on blockchain for security.
✅ Immutable Verification – Verifies if a report hash matches the one recorded on-chain, preventing tampering.
✅ Owner-Restricted Access – Only the contract owner (hospital/admin) can store or update reports.
✅ Transparency & Auditability – Anyone can view report metadata and verify authenticity.
✅ Celo Network Integration – Deployed on the Celo Sepolia Testnet, enabling low-cost, eco-friendly transactions.
