Build a Transparent Blockchain Supply Chain System
Leverage blockchain technology to track goods from origin to delivery, enhancing transparency, trust, and tamper-proof record-keeping in the supply chain.Supply chains often suffer from lack of transparency, counterfeit goods, and data tampering. Blockchain provides a shared, immutable ledger that every stakeholder can rely on, ensuring the authenticity and traceability of every product.
Create a DApp where manufacturers, suppliers, shippers, and retailers can record supply chain events. Each update is logged to the blockchain with timestamps and metadata, ensuring full traceability and accountability for every item.
Multi-Party Access
Different actors (supplier, manufacturer, shipper, retailer) can write and view updates to a product's lifecycle.
Immutable Product History
Every action (packaging, transit, delivery) is stored on-chain, ensuring tamper-proof records.
QR Code Verification
Scan a QR code to view the entire verified journey of the product from origin to shelf.
Smart Contract Automation
Use smart contracts to automate event recording and milestone validations in the supply chain.
Each product has a unique ID that maps to a smart contract containing its lifecycle events. Stakeholders add updates as it moves through the supply chain. A React frontend allows real-time event submission and QR code-based tracking, while the data is permanently stored on the blockchain.
- Solidity contracts for product event logs
- Role-based access for different supply actors
- QR code generation and scanner integration
- IPFS for optional documentation storage
- React frontend with event submission forms
Blockchain
Polygon or Ethereum for smart contract deployment
Smart Contracts
Solidity with role-based supply chain logic
Frontend
React.js with Ethers.js and QR code library
Storage & QR
IPFS for certificates, QRCode.react for tracking links
1. Create Product Lifecycle Contract
Write a smart contract that logs product events with metadata and timestamps.
2. Design Frontend for Event Input
Develop forms for stakeholders to add events and scan or input product IDs.
3. Role Assignment & Verification
Assign roles like Manufacturer, Shipper, Retailer using smart contract access control.
4. Generate and Display QR Codes
Link QR codes to product IDs for tracking and history lookup.
5. Test Real-World Supply Scenarios
Simulate a full product journey with multiple actors and ensure real-time integrity.
Track Products with Trust and Transparency
Build a blockchain-based system that brings integrity and visibility to every link in the supply chain.
