Proof of Med

Proof of Med is a decentralized solution that ensures the authenticity of medical prescriptions in online pharmacy transactions using Zero-Knowledge Proofs (ZKPs). By leveraging Noir for circuit design, Sindri for proof generation, zkVerify for on-chain verification, and Educhain Testnet for blockchain execution, Proof of Med provides a trustless system that mitigates fraudulent prescriptions while maintaining patient privacy.

Key Features

• Privacy-Preserving Prescription Verification: Validates prescriptions without exposing sensitive patient data.

• Decentralized & Secure: Uses Educhain Testnet for verifiable and immutable prescription records.

• Scalable Proof Generation: Utilizes Sindri's proof market to offload computationally intensive ZKP generation.

• Seamless Integration for Pharmacies: Ensures only legitimate prescriptions are fulfilled, preventing unauthorized medication orders.

How It Works

1. Prescription Input

   • Doctors input prescription details, including patient information, medication name, dosage, and other relevant details.

2. ZK Circuit Execution

   • A Noir-based ZK circuit is used to validate the prescription’s integrity without revealing private patient data.

3. Proof Generation

   • Sindri generates a ZK proof for the prescription data, ensuring scalability and efficiency in the verification process.

4. On-Chain Proof Verification

   • The ZK proof is submitted to ZKVerify, which checks the proof’s validity before allowing the prescription to proceed.

5. Order Fulfillment

   • Once verified, the pharmacy processes the order, ensuring that only legitimate prescriptions lead to medication dispensing.

Smart Contract Roles

• Owner – Administers the contract and assigns roles.

• Doctor – Authorized to issue prescriptions.

• Pharmacy – Manages inventory and fulfills orders based on verified prescriptions.
