Track Food from Farm to Table Using Blockchain-Powered Supply Chain

Food fraud, safety issues, and lack of transparency in supply chains impact public health and consumer trust. Blockchain enables immutable and real-time recording of food journey data, increasing accountability and making recalls faster and more precise.

Design a smart contract-enabled system where farmers, distributors, and retailers log transactions at each stage of the food supply chain. Consumers can scan a QR code to verify the product’s origin, handling, and journey details on-chain.

Each food item is assigned a unique ID. At each supply chain stage, relevant metadata is recorded (e.g., batch, temp logs, timestamps) and written to a smart contract. IPFS can be used to store additional documents like certifications or receipts. Consumers query this data via a QR code lookup interface.
