Design of a Blockchain-Enabled Traceability System Framework for Food Supply Chains.

Area of Science:

• Food Science and Technology
• Computer Science
• Supply Chain Management

Background:

• Centralized food traceability systems face challenges due to complex, disparate user systems.
• Decentralized systems offer a more favorable approach for comprehensive food product tracing.
• Integrating diverse supply chain technologies remains a significant hurdle.

Purpose of the Study:

• To develop a decentralized traceability system framework for food products.
• To leverage blockchain and RFID technologies for enhanced data management and security.
• To create a scalable solution for industrial food supply chain tracking.

Main Methods:

• Development of a decentralized data storage platform using consortium blockchain (Hyperledger Fabric 2.0).
• Integration of Radio Frequency Identification (RFID) technology for data collection at the packaging level.
• Design of a novel blockchain-enabled data structure embedded within RFID tags.

Main Results:

• The proposed system provides decentralized data management with guaranteed data security through blockchain algorithms.
• Information is recorded as linked blocks on the RFID tag and simultaneously transmitted to the blockchain platform.
• The system requires no battery, operates with proximity RFID readers, and is applicable to paper packaging.

Conclusions:

• The embedded blockchain technique within RFID tags offers a simplified and secure method for product tracking.
• The developed system demonstrates potential for industrial scalability in food supply chain management.
• This approach addresses the limitations of centralized systems by enabling seamless data interaction across the supply chain.
