How will blockchain help food safety?

Time : 28/09/2021 Author : m9pr5o Click : + -
        In the modern food industry, nothing is more valuable and difficult to maintain than quality and safety. For this reason, producers need to carefully cultivate and process the natural environment such as land, water and air. But even so, due to the refinement of production division under globalization, there are more and more participants in the intermediate link from the source of food production to the final consumer, and the distance to be crossed is also getting longer and longer. The good news is that real food can travel thousands of miles to reach consumers' tables. The bad news is that the trust maintained by the market and local conditions can only be replaced by the advertising of producers. Under the fierce competition, food safety accidents and even rumors may cause an irreversible blow to this trust.
        In the face of the continuous extension of the food industry chain, the business opportunities are self-evident. Quality brings good reputation, safety assurance confidence, and consumers are willing to pay a premium for healthy food. What we need to do is to find a new fulcrum for the industrial chain, integrate the quality control system and responsibility process, so that food can prove itself safe. How do you do it? On May 20, 2019, the CPC Central Committee and the State Council issued the opinions on deepening reform and strengthening food safety work, proposing to improve the ability of food safety risk management and promote "Internet + food" supervision. Blockchain is the core technology and link of "Internet + food" regulation. Many people know bitcoin, but few know blockchain.
        But in fact, the two are one and two sides. When financial regulators of various countries pointed out the harm of speculation and speculation of virtual currency time and again, blockchain, as the underlying technology of virtual currency, has long been used in reality and has become a sharp weapon for technological innovation and transformation. 2018 is the first year of the implementation and application of blockchain technology. Wal Mart,, Alibaba and other business giants have combined blockchain technology with the field of food safety. Technology giant IMB has set up a special business line to help the food industry integrate blockchain into the supply chain management process. The actions of business giants have brought about the rapid landing of technology and applications. This in itself shows that food safety is the most potential area for blockchain technology to serve the real economy.
        This potential is determined by the characteristics of blockchain technology. As the underlying technology of virtual currency, according to the design, each computer can check the work of other computers. Whether it is mining virtual currency or trading between buyers and sellers, new changes will be jointly tested by all nodes in the network and recorded in the data block for anti-counterfeiting and production of the next block. The records formed by various transactions are end-to-end and witnessed by the participants, so they become almost impossible to tamper with. Blockchain gets its name from this, and its formation process coincides with the new pain point of food industry production. It can be seen that the four basic characteristics of blockchain are decentralization, tamper proof, time tagging, and low cost of smart contract signing.
        Decentralization means that each node in the food production, transportation and sales process can contribute data independently; Tamper proof and time tags ensure the credibility of the data; The low cost of smart contracts means that the integrated food safety process can add more node information to better restore the whole process of food production and consumption. With the advent of 5g era, supplemented by Internet of things technology, the information of each node is changed from being filled in by people to being collected by automatic equipment, which can further improve the credibility of food safety records. As early as 2017, established the " quality traceability anti-counterfeiting alliance" and cooperated with Horqin cattle industry to automatically collect information and write it into the blockchain by using various devices in the links from slaughtering to shipping to delivery, so as to facilitate consumers to "trace" the production process of beef with one click.
        In June this year, Wal Mart China announced the official launch of the blockchain traceability platform. It is reported that the first batch of 23 commodities have been tested and entered the platform, and more than 100 commodities will be launched successively in the second half of this year, covering more than 10 categories such as packaged fresh meat, vegetables, seafood, etc. By scanning the QR code on the commodity, consumers can understand the source of commodity supply and the geographical location, logistics process time, product inspection report and other details received by Wal Mart. The more categories involved in this cross-border cooperation, the more important it is for food producers to participate in practice. Because different food categories have different production standards, for example, foods with strict requirements on storage temperature must be added to the cold chain.
        The temperature sensor implanted in the cold chain transport vehicle records the temperature changes during transportation, which can be used as a reference for quality traceability. Recall those food safety crises that once shocked the industry. Whether it is mad cow disease in Europe and the United States, or melamine milk powder and Baijiu plasticizer in China, real experts can always sort out the quality control keys between upstream and downstream processes, and arrange information nodes in the corresponding links. Blockchain technology will faithfully record all production processes, which can not only shorten the traceability time, but also be used in product recall, product warranty management, transportation management, etc. Once a food safety crisis occurs, we can also accurately find the cause of the problem and respond in time.
        The race to win and maintain consumer confidence has never stopped, and blockchain technology is introducing this race to a new track. Those large enterprises that take the lead naturally see the opportunities. Once mature applications are launched, the global food industry will enter a new world. For the specific application of blockchain technology in the agriculture, animal husbandry and food industry, aidanconnolly, the former global vice president and chief Innovation Officer of otech, will bring the latest share on vivqingdao2019.
