“Only companies with self-iteration, self-innovation and self-reflection can become truly great companies†This is a sentence that Liu Qiangdong said in an internal letter to all Jingdong employees on March 30. Recently, Jingdong has repeatedly been complained by consumers on product issues, especially in the fidelity of food, cosmetics, overseas purchases and other products, so that Jingdong suffered the biggest crisis of trust in history. This is absolutely unacceptable for Liu Qiangdong, who has always been strong and regards "customer first" as the corporate DNA. In order to solve this problem, Liu Qiangdong reiterated and emphasized in his internal letter the determination to apply blockchain technology to solve product anti-counterfeiting, and the breakthrough of application is the traceability system of the entire product supply chain. At present, Jingdong has signed direct and direct supply agreements with product suppliers around the world, using blockchain technology, from production, inspection, to transportation, sales, supervision, etc., the information of each link is true and transparent. Completely solve the consumer crisis of trust. Liu Qiangdong’s affirmation of the blockchain technology is believed to have shaken some people who have doubts and wait-and-see attitudes towards the blockchain. How did the blockchain suddenly burst into flames? In fact, the word blockchain really enters the public's sights only for more than half a year, and the time is short, but now when blockchain technology has become a consensus of the government, enterprises and people in the commercial society, Then it will naturally become the slogan of being chased. However, how to find the application value that can maximize the blockchain, how to create the maximum profit value, and how to achieve the landing on the technical level is the problem that needs to be solved urgently. In February of this year, the People’s Daily used a full-page version as a spokesperson for the blockchain, elaborated on the core technology and application prospects of the blockchain, and emphasized that the blockchain is the cusp and the future. In the article, the People’s Daily listed four application areas including traceability, finance, public welfare, and supervision. It is no exaggeration to say that blockchain is subverting traditional traceability in the field of product counterfeiting and traceability and anti-counterfeiting. The rapid recognition of technological development. I believe that most people still can't accurately explain what it is when they talk about the blockchain, but there is always a feeling of unclearness. In the news, in the circle of friends, in daily social interactions, etc., there are full of insights and fantasies about the blockchain. If you don't know the blockchain, you can't talk about the blockchain, and you may become the object of being "contempted". You may even feel that you can't keep up with the times. The official definition is that a blockchain is a chained data structure that combines data blocks in a chronological order in a sequential manner, and cryptographically guarantees a non-tamperable and unforgeable distributed ledger. In layman's terms, it solves the problem of “credit†and reduces the cost of credit when participating in multiple parties. Data cannot be tampered with and forged. Perhaps this is why the People’s Daily has applied the blockchain to traceability as the first application area. At present, in addition to Jingdong, well-known companies such as Tencent, Taobao, Wal-Mart, and Maotai have set up technical R&D teams or cooperated with third-party technical teams to apply blockchains to their supply chain traceability systems. This means that blockchain traceability is no longer a concept term for nothingness, but a reality that has become visible. Why does the blockchain achieve food traceability? As early as 2003, the government made every effort to promote the construction of food traceability system, but the effect was not obvious, so that food safety problems have been repeated. In fact, the traditional method of traceability is a central accounting mode, and the entire traceability process is susceptible to human factors. For example, if you are a pig farmer, when the consumer has eaten your pork and has a safety accident, it will not be able to go to you when you trace it back, because it involves too many parties, buy it. Whether the pig feed will be fraudulent, whether the merchants who purchase the pigs will be fraudulent, whether the logistics will be fraudulent, whether the warehouse will be fraudulent, dealers, distributors, agents, processing factories, etc. may have fraud and tampering data, because everyone The central accounting method is used. The parties record the data and information in a traceability system. Except for themselves and the system provider, others do not know. The unreliability of the data and the risk of being tampered with by the parties are greatly increased. . The decentralized distributed accounting method of the blockchain solves this problem. The biggest feature of distributed accounting is universal account bookkeeping. Everyone has a secret key address. When any party related to the goods uploads data and information, the other party will synchronize accounting and This data and information is stored, so it is completely transparent. If someone tampers with the information, the other parties in the system will not agree, and the system itself will not recognize it. At present, the application prospects of the blockchain in the traceability of commodities have been widely recognized, and the theoretical and technical aspects have been basically realized. However, if it is really put into commercial application, it may take some time, because after all, it must face the verification and running-in of various links such as business reconstruction, system construction, personnel training, operation and maintenance. 5 trillion market size or the largest source of blockchain traceability in the blue ocean In 2017, the total revenue of China's catering industry was 3.96 trillion yuan, a year-on-year increase of 10.7%, accounting for 10.8% of total social retail consumption. According to this speed, the market size will reach 5 trillion yuan by 2020. Catering is just needed, and it is sustainable. Its development will directly affect the development of many industries such as agriculture, animal husbandry, logistics and storage related to its supporting. The application of blockchain traceability technology can not only solve foods. The problem of safety is to greatly improve the operational efficiency and reduce operating costs in the entire chain. It can be said that the catering industry is the best experimental ground for the blockchain traceability technology. As the market scale continues to expand, it is likely to be its largest application blue ocean.
