Blockchain-Based Healthcare Payment System

Objective:

To build a secure, transparent, and automated payment system for healthcare services using blockchain technology, ensuring faster claim settlements, reduced fraud, and direct transactions between patients, providers, and insurers.

Key Features:

Smart Contracts for Payments – Automate billing, claim approvals, and settlements.

Transparent Transactions – All payment-related records are auditable and immutable.

Fraud Prevention – Verifiable billing reduces false claims and overcharging.

Decentralized Records – Access control for sharing medical bills and claim data securely.

Real-Time Processing – Immediate payments upon claim validation.

Multi-Party Access – Patients, providers, and insurers interact on a single platform.

Tokenization (optional) – Use of crypto tokens or stablecoins for seamless payments.

Technologies Used:

Blockchain Platform: Ethereum, Hyperledger Fabric, or Quorum

Smart Contract Language: Solidity (Ethereum) or Chaincode (Hyperledger)

Frontend: Angular / React.js for user dashboards

Backend: Node.js / Python for API and business logic

Data Storage: On-chain payment metadata; off-chain patient records (e.g., IPFS or encrypted cloud)

Wallet Integration: MetaMask, Coinbase Wallet, or institutional wallets

Encryption: AES/RSA for sensitive data

How It Works:

Patient Visits Provider: Medical services are recorded and billed digitally.

Smart Contract Activation: Billing info is sent to a smart contract.

Claim Validation:

Insurer verifies eligibility and authenticity using blockchain records.

Smart contract checks conditions (e.g., policy limits, service codes).

Automatic Payment:

Once approved, payment is released from insurer to provider instantly.

Optional: Co-payments from patient are also handled via wallet.

Audit Logging: All steps (claim, approval, payment) are logged immutably.

Benefits:

Efficiency – Speeds up claim and payment cycles with automation.

Cost Savings – Reduces administrative overhead and paperwork.

Security – Data is encrypted and stored securely with full traceability.

Transparency – All parties have access to the same trustworthy records.

Fraud Reduction – Prevents duplicate or exaggerated claims.

Patient Empowerment – Patients have visibility and control over their billing and insurance processes.
