Core Viewpoint - Blockchain technology offers unique advantages such as real-time recording, data immutability, and full traceability, providing a breakthrough for precise food quality tracing and enhancing food safety for consumers [1][2]. Group 1: Blockchain Technology in Food Safety - Blockchain establishes a decentralized distributed ledger for each batch of food, creating a "digital ID" that tracks the entire process from planting to consumption, ensuring data integrity and transparency [1][2]. - The technology allows consumers to scan and trace key information throughout the supply chain, enabling regulators to conduct thorough oversight and improving collaboration efficiency among enterprises [1][2]. Group 2: Current Applications and Innovations - Various regions are increasing the application of blockchain technology to build food quality tracing systems, with Fujian province leading by establishing a raw grain quality tracing platform that integrates with the provincial food safety information management platform [2]. - Shandong province is promoting a management system that enhances product quality tracing for over 100 enterprises, while Hubei province has developed a public service platform for comprehensive quality safety tracing across the entire food supply chain [2]. Group 3: Challenges in Implementation - The "digital divide" hinders widespread adoption, as small farmers often lack digital literacy, smart device access, and robust network infrastructure, creating a gap with blockchain implementation requirements [3]. - Ensuring the authenticity of source data remains a challenge, necessitating a trust generation mechanism that combines technology and regulatory measures [3]. - High costs associated with deploying blockchain and related technologies pose a barrier, particularly for small enterprises and farmers, highlighting the need for sustainable incentive mechanisms to lower entry costs [3]. Group 4: Need for Comprehensive Framework - Building a food quality tracing system requires more than just blockchain technology; it necessitates regulatory support, standardized practices, and a cultural shift towards quality safety [4]. - Governments should establish legal frameworks and policies for blockchain applications in the food sector, clarifying data ownership and privacy boundaries [4]. - A unified standard for data collection, transmission, storage, and exchange across the industry is essential to break down data barriers and facilitate information sharing [4].
