Blockchain traceability information

1.

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

2.

In the heat wave of "embracing blockchain" in 2018, who can take the lead in finding application scenarios and launching landing projects has become the most important part of the competition

among them, traceability and anti-counterfeiting is considered to be one of the most promising areas for blockchain implementation, and also the first area for giants to compete for blockchain technology implementation. In China, Chongqing, Hangzhou and other cities have taken the lead in "testing" the application of blockchain in food traceability; Tmall, Jingdong and other e-commerce giants also use blockchain technology in their respective systems for traceability and anti-counterfeiting

What are the advantages of blockchain traceability compared with traditional traceability? What pain points can blockchain technology solve in the traceability and anti-counterfeiting business? Can blockchain technology open a new chapter of traceability and anti-counterfeiting business

3. 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. "

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 management

2. 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

5. Different from China, all kinds of laws stipulate that currency must be issued and managed by the state. Only the people's Bank of China has the power to issue currency. It is illegal for anyone else to do so. Even the points issued by various enterprises with certain monetary attributes are not allowed to establish a two-way exchange mechanism with RMB.

6. Vonetracer platform of Shanghai wangchain information technology focuses on grain and oil, vegetables, fruits, medicinal materials, aquatic procts and other instries
