Blockchain for Blood Donation Registry - Project Guide for IT and Computer Engineering
1. Introduction
The Blockchain for Blood Donation Registry project aims to create a transparent and secure system for managing blood donations and ensuring the availability of blood. Blockchain technology is leveraged to enhance trust, traceability, and efficiency in the blood donation process.
2. Objectives
- Establish a tamper-proof registry for blood donors and donations.
- Simplify the process of matching donors with recipients.
- Enhance transparency in the blood supply chain.
- Ensure accountability and traceability in blood distribution.
- Provide a secure platform for donors, recipients, and hospitals.
3. Key Components
3.1 Blockchain Platform
- Use Ethereum, Hyperledger Fabric, or Polygon for secure data handling.
- Ensure scalability and low transaction costs.
3.2 Smart Contracts
- Automate donor registration, blood request matching, and distribution processes.
- Define rules for eligibility checks and inventory management.
3.3 User Roles
- Donors: Register and donate blood securely.
- Hospitals/Blood Banks: Manage blood inventory and match requests.
- Recipients: Request and receive blood donations.
- Regulators: Monitor the system for compliance and transparency.
3.4 Decentralized Storage
- Use IPFS or Filecoin to store donor details and donation records securely.
- Store metadata and hash values on the blockchain.
3.5 User Interface
- Develop portals for donors, hospitals, and regulators.
- Provide features for managing donations, inventory, and requests.
4. System Architecture
4.1 Workflow
1. Donors register and provide consent for blood donations.
2. Donation details are securely recorded on the blockchain.
3. Hospitals or recipients submit requests, and the system matches them with available blood types.
4. A traceable record is maintained for each donation and distribution.
4.2 Data Management
- Store donation records, inventory levels, and requests on decentralized storage.
- Maintain hash values and metadata on the blockchain.
4.3 Access Control
- Use smart contracts to enforce role-based access permissions.
- Ensure sensitive donor and recipient information is encrypted.
5. Development Frameworks and Tools
- Blockchain SDKs: Truffle, Hardhat, or Remix IDE.
- Programming Languages: Solidity, JavaScript, or Python.
- Libraries: Web3.js, ethers.js, or OpenZeppelin.
- Storage: IPFS or Filecoin for decentralized storage.
- Frontend Frameworks: React.js, Angular, or Vue.js.
6. Implementation Steps
6.1 Setup the Blockchain Network
