[People’s Bank of China Governor Zhou Xiaochuan at the press conference of the 13th National People’s Congress on March 9th, when answering reporters’ questions about blockchain, Ai Gu, and virtual currency, pointed out that “inappropriate products should stop. Some promising ones have to be tested and then promoted." As one of the best application scenarios for blockchain, food traceability has recently been tested and verified by Wal-Mart, JD.com, Ali, and TAC traceability chains. Then, what are the opportunities and challenges that food traceability will face in the process of commercial promotion?] For the food chain tracing model based on blockchain, the government, enterprises and consumers have basically reached a consensus: the use of blockchain technology can truly realize traceable food safety and solve the last mile of food safety. In short, blockchain technology enables a point-to-point direct interaction, making the efficient, large-scale, uncentralized agent information interaction a reality. Blockchain technology allows users to view all transactions simultaneously and in real time. For example, in food safety, through the blockchain, consumers and processors can not only realize transparent transactions, but also inquire about all the journeys that this product has experienced from source, production, to delivery, and on-shelf sales. For C-end consumers, the service of the blockchain traceability platform is very convenient. Simply scan the QR code on your smartphone and you can easily access product information on the blockchain traceability platform, such as animal birth dates, antibiotic use, vaccination, and livestock harvest locations. (The University of British Columbia researcher Hu Yaxi conducted a test in 2016 to determine the portion of exotic animals in ground beef.) 01 Prevention of foodborne diseases Food traceability According to the US Centers for Disease Control and Prevention, food-borne pollution causes 48 million Americans to become sick each year and more than 3,000 deaths. Nearly half of the diseases are produced, and poultry cause the most deaths (mainly due to Listeria and Salmonella). When a pollution incident occurs, in the traditional mode, food flow information is recorded through an Excel account or a centralized database. If there are problems in the middle link, such as missing records or errors, the company may take days or even weeks to track the source of the infection and recall the corresponding product. The recent news that “Moutai data leaks caused Moutai to lose millions†is a flaw that exposes traditional traceability. With blockchains, supply chain processes can be completely transparent and traceable, from any point in the food chain to the source. For this reason, retail giants such as Wal-Mart and Kroger are seeking to prevent a $48 million loss from eating-borne diseases each year through blockchain. 02 Put an end to counterfeiting Food traceability There are a lot of people paying attention to the 3.15 evening party every year. Consumers are more worried about whether they have bought fake and shoddy products, and companies are worried about whether they will be on the black list. Despite the exposure and investigation of a batch of counterfeit products every year, the problem remains the same. The relevant departments have also increased supervision and enforcement. Relevant enterprises have also adopted anti-counterfeiting systems and established counterfeit product reporting channels, but the effect is minimal. Wang Pengfei, the founder of the TAC traceability chain, believes that the pursuit of profit-seeking behavior by unscrupulous interests is the most fundamental cause of the proliferation of counterfeit and inferior products. Eliminating counterfeit and shoddy behavior requires comprehensive management from a management and technical level. The practice for many years shows that the anti-counterfeiting system under the traditional central database service mode is not successful in terms of technical level prevention. Blockchain technology guarantees the authenticity of products stored and streamed on the chain. This authenticity endorsement comes from the high security level cryptographic algorithms behind the blockchain. Using blockchain to solve the problem of preventing counterfeit and shoddy products, Jingdong and Carrefour have seized the opportunity. Carrefour recently announced that it will run blockchain technology to track chicken production in the Auvergne region. Consumers can use smart phones to scan packages. Code, get information on feeding location, feeding method, etc. With the popularity of the blockchain concept and the successful effects of blockchain technology by well-known companies, more and more companies are willing to put their products on the market. Enterprise winding is usually divided into self-research and outsourcing (third-party cooperation). Large enterprises such as Jingdong and Ali use the first method. Subject to factors such as technology accumulation, financial costs and time costs, small and medium-sized enterprises usually use the second way to go online. With the increasing demand for enterprise chain, there will inevitably be professional providers and platforms that provide blockchain traceability services. At present, the fields of tracing applications such as Tmall and Jingdong are mainly in the field of e-commerce. Domestic companies have targeted the $300 billion market. In May 2017, Wang Pengfei, the founder of the TAC traceability chain, led the team to formally start the project. The purpose of the TAC traceability chain is to digitize the life cycle of goods based on blockchain technology and promote the construction of commodity traceability systems. Realize the information collection and recording from the source, trace the source of raw materials, production process, inspection batch, logistics flow, anti-counterfeiting and other actions. (Taiwan framework for TAC traceability chain) “The demand for enterprise chaining is bigger than imagined,†said Wang Pengfei. “After the festival, many companies took the initiative to find us. They hope to use the TAC traceability chain to improve the quality control of their products. At present, we have selected a famous domestic red wine. As the first partner in the field of wine, the trading company reached a chain cooperation of 30,000 products to access the TAC traceability chain." 03 Food traceability challenge Food traceability In the actual commercial promotion process, there are still many constraints on the promotion of the blockchain food traceability process. The first is that the amount of information that can be processed by the blockchain is limited. At present, the performance of the underlying protocol is generally poor. For example, the transaction volume of 25 or so per second in Ethereum is also criticized. In fact, there are already many solutions to deal with these problems. For example, the TAC traceability chain develops its own public chain, and integrates with Ethereum to cross-link the data of various business scenarios to the business sub-chain. This architecture can take into account the stability of Ethereum and the application of TAC public chain. Flexible and scalable. The TAC traceability chain currently handles three digits per second. Secondly, for the authenticity of the information on the chain, some perfectionists disagree. It is understood that the TAC traceability chain also attaches great importance to the information authenticity of the uplink link, and will design a three-dimensional chain-up mechanism to resolve this problem and ensure that the information entered in the uplink link is true and reliable. For example, in the initial information collection, the use of sensors and other means of machine collection to eliminate human interference factors; for example, the real name system, audited by the main chain of the sub-chain, the local quality supervision department involved in product inspection; for example, by the manufacturer and this link The person in charge signs a contract with legal effect, such as an agreement between the milk powder manufacturer and the dairy farmer, and the dairy farmer must be legally responsible for the data given... In addition, different traceability technologies and standards between different platforms may lead to slow progress in the popularization of commodity traceability. For example, a food is not only sold on Tmall, but also sold in Jingdong and No. 1 stores. If the traceability systems of the two platforms are not uniform, the traceability effect is limited. In Wang Pengfei's view, it is the competition between these large platforms that brings innovation opportunities and growth opportunities to start-ups like the TAC traceability chain. The advantage of the TAC traceability chain compared to these large platforms is that there is no existing business boundary, which can better assist the technical service companies on the platform to serve their own branded corporate customers, and can better empower the brand enterprises and let the brands With the help of the TAC traceability platform, enterprises can achieve faster and lower cost. These challenges faced by food traceability, like the troubles of growing up, need to be actively addressed, and they can all be actively addressed. 315 is coming to the forefront, blockchain technology can solve food quality, food safety issues, and achieve large-scale commercial promotion, let us look forward to!
