1. Of course. One of the characteristics of blockchain is decentralization, traceability and non tampering of information. Now commodity traceability has always been a hot area for blockchain technology landing. As early as 2017, tmall global launched the global traceability plan to track the information of imported commodities by using blockchain technology
the traceability of blockchain technology is used to increase the traceability and security of commodities through the deep combination of logistics management, commodity anti-counterfeiting, commodity traceability, manufacturing management, instry collaboration and other fields. Password finance, focusing on blockchain information.

2.
The three characteristics of blockchain are well known, that is, decentralization, transparency and non tampering. The tamper proof feature makes blockchain used in many places. Such as proct traceability, privacy protection and so on
because the proction process it traces back to is artificially uploaded, so even if it is tamperable data, the authenticity of the data can not be guaranteed, and the substantive problem still can not be solved
generally speaking, although blockchain has brought great benefits, it is not perfect after all. However, blockchain technology has promoted the development of the times, and I believe its future is worth looking forward to
3. Let's take vonetracer, the blockchain traceability platform of wangchain technology, as an example. Blockchain technology can record all links such as proct planting, factory manufacturing, logistics transportation, warehousing and sales on the chain. After users get the proct, they can scan the QR code to see the traceability of the proct.
4. With the help of blockchain technology and alliance chain node, wangchain technology integrates and writes the information of commodity raw material circulation process, proction process, commodity circulation process and marketing process into the blockchain, and uses the tamper proof attribute of the blockchain to realize the whole process traceability of one thing one code
5. What are the e-commerce sources of blockchain traceability< According to the introction, the food supply chain involves many links such as proction, transportation, storage and sales, so the control of food quality is extremely complex. As a technology with decentralization as the core, the block chain is open and transparent among all parties, So as to effectively form a chain of information and value sharing. Because the blockchain has the feature that the data can not be tampered with, once the data is uploaded, it can not be changed. Therefore, it is easier to make the source traceable and the destination traceable, and truly realize the responsibility traceability< Specifically, the identification number attached to each batch of goods is unique, recording a series of information from planting, processing to store sales. By scanning the QR code on the proct label, consumers can fully grasp the real information of each stage from the source of the supply chain to the terminal. This approach can not only enhance consumers' impression on the quality of Carrefour procts, but also enhance their trust in Carrefour brand; To some extent, it can effectively urge the upstream of the supply chain to improve the quality and safety level
so far, the food safety issues that consumers are most concerned about will also be strongly guaranteed. Carrefour believes that the use of blockchain can effectively help consumers regain confidence and rebuild their trust in the food instry
in fact, it has become a trend to apply blockchain technology to commodity traceability scenarios. Previously, tmall also applied blockchain technology to commodity traceability scenarios in this year's "double 11". It is reported that in tmall International Mall ring the "double 11" period, the commodities traced by blockchain will cover more than 100 countries and regions, and the number of commodities will reach 150 million. The commodities involved mainly include diamonds, imported milk powder, imported health care procts and other cross-border commodities. In addition, Wuchang rice, Maotai (600519, Guba) and other high-end liquors and Pingwu honey will also use blockchain traceability
Third, the combination of online and offline
Suning e-buy launched the blockchain commodity traceability system ring "618" this year. It is understood that ring the "618" period, Suning e-buy's self-developed block chain commodity traceability system was fully opened in Suning e-buy's online and offline stores, with two lines to ensure the quality of goods and reject fakes. Suning applies commodity anti-counterfeiting traceability blockchain technology to track and record the proction, processing, transportation, circulation, retail and other links of commodities, which is realized through the wide participation of all parties in the upstream and downstream instries. Suning easy to buy users in the purchase of goods, as long as the scan proct traceability source code, you can "one click" query proct information< (4) it is suitable for regulatory or instrial closed-loop scenarios.
Wang Maolu, chairman of consensus digital, once told Securities Daily that "blockchain technology is suitable for anti-counterfeiting traceability of commodities, especially for regulatory or instrial closed-loop scenarios. The combination of the two characteristics of blockchain data non tampering and transaction traceability can eradicate the problem of fake and shoddy procts in the process of proct circulation in the supply chain, solve the trust problem existing in the traditional traceability, and protect the rights and interests of consumers. "

6.
A: first, the connotation of blockchain
blockchain is a distributed shared ledger and database, which is decentralized, tamper proof, traceable, collective maintenance, open and transparent
Agricultural traceability is the most complex and difficult part of food traceability. At present, there is no complete agricultural proct traceability system based on food safety proction and whole process supply chain management2. The most important part of the construction of agricultural traceability system is "one center and three moles", which is a traceability cloud data center and three moles of procers, regulators and consumers
Third, composition of blockchain
blockchain system is composed of data layer, network layer, consensus layer, incentive layer, contract layer and application layer
7. The two have different meanings
the purpose of proct anti-counterfeiting is to identify the authenticity of goods and prevent counterfeiting. And proct traceability is to use blockchain technology to check the source information of goods. Cryptography focuses on blockchain information.

8. The traceability system of the traditional mode either uses today's centralized account book mode, or is separately recorded and kept by various market participants. It is an information island mode. In the traditional mode, each market participant maintains an account book by himself, but no matter it is an entity account book or an electronic purchase and sales position system, The owner can tamper or fabricate after the event at will. Eventually, accountability cannot be traced quickly
jinwowo blockchain technology is the internal logic of applying blockchain technology to traceability, anti-counterfeiting, and optimization of supply chain. The core technology of blockchain is decentralization, real-time reconciliation ability in registration and settlement scenarios, and tamper proof and time stamping in data storage scenarios. For traceability, anti-counterfeiting, supply chain scenarios to provide a strong guarantee.

9. Enterprise integrity is the foundation of enterprise operation. The non tamperability of blockchain technology greatly ensures the authenticity of data sources. Especially in the field of e-commerce enterprises, jinwowo blockchain technology will form a detailed list of platform transactions, completely trace the source of all procts and transaction process, and build a protection wall for enterprise integrity management.
10. Experience of participating in quality ecation
in 2006, according to the arrangement of the unit, I participated in the training of "capital staff quality ecation". Through their own efforts to better complete the learning tasks of various subjects, of course, the results behind the condensation of their own hard work and sweat. This training and study has benefited me a lot, brought me new ideas, solved many puzzles in my work, inspired me to study harder in my future work, and constantly improve my professional level and comprehensive quality
1. Clear purpose, correct attitude and serious study
e to years of busy work and lack of centralized training and learning, I also feel that I need to update my knowledge and broaden my horizons in the new situation. This training includes four courses: practical writing, practical legal basis, self-development and team management. In the class, I can hear different opinions and suggestions from other teachers, and many teachers can boldly put forward their own ideas and ideas, and have a free talk with the students, which makes me feel open-minded and benefit a lot. A lot of theoretical knowledge is thus subtly transformed into skills and resources that can be used in practical work. Therefore, I cherish this learning opportunity very much. In learning, I have a correct attitude, try my best to overcome the difficulties that children need to take care of when they are young. I listen carefully, finish my homework on time, abide by the rules and regulations of the school, do not be late or leave early, and complete this training with a good mental outlook< Second, pay attention to learning methods and improve learning efficiency
e to on-the-job learning, it is necessary to arrange learning time reasonably. In order to improve the efficiency of learning, before each class, I carefully preview the relevant content, make full preparation before class, and listen to the class with questioning and knowledge-seeking mood. During the lecture, I made corresponding notes on the key points and difficulties, and thought positively with the teacher's ideas. When it comes to the part I don't understand, I use the time after class to ask the teacher and other students for advice. I actively complete all the assignments assigned by the teacher. I often check my understanding and mastery of what I have learned. I insist on self-study for no less than one hour every day, and record the difficulties and doubts encountered in self-study. I have a clear idea when I go to class, listen to the teacher with questions, actively participate in the teacher's questions, classroom speeches and discussions, and strive to improve my learning efficiency
thirdly, overcome difficulties, make overall plans and improve learning effect
in order to ensure that there is no mistake in work and study, the only thing we can do is to sacrifice more rest time. In order to devote myself to study, all social activities and recreational activities that conflict with study time are declined. My children are also taken by my mother-in-law. When I need to work overtime, I try my best to arrange it in the evening to ensure the time for class and homework. In addition to using the rest time, I also postpone the rest time in the evening. When it comes to the exam, I can't read or study ring the day, so I often review in the evening. Only "learning for application" can reflect the mastery and application ability of knowledge. Because I am the Secretary of the Youth League branch of my unit, I have benefited from this period of study. In the future work practice, the new ideas, new ideas and new methods in the study can run through the work automatically and spontaneously, which has improved the level of official documents, enhanced the legal awareness, and greatly opened up the creativity and ideas in the activities of the Youth League branch, Team management has been further improved and strengthened
looking back on the achievements of my study, I feel very happy to have the opportunity to join the learning ranks of "capital staff quality ecation". In the future, I will continue to study and constantly update my knowledge, so that my work level and professional quality can always keep up with the requirements of work and the development of the times<
