Build a Transparent Blockchain Supply Chain System

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.

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

• Solidity Role-Based Access
• QRCode Generator in React
• Supply Chain DApp Example
