Blockchain tracing

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. At present, there are many companies that do anti-counterfeiting traceability system on the market, but there are few platforms that really implement blockchain technology. Miaowa anti-counterfeiting traceability platform is the blockchain technology that is used to collect data distributed in different nodes and verify the authenticity of data on the premise of ensuring that the data can not be changed

7. How to get to London is like you don't know how to get to London! "?

8. It can provide information of procing area for consumers and make people feel more at ease.

9. Anti counterfeiting traceability through the traditional two-dimensional code technology has been able to solve the problem, the pain is that the anti-counterfeiting data stored in the central structure, easy to tamper with, credibility is not strong. It happens that the characteristics of blockchain are very consistent with anti-counterfeiting traceability. Let's review the four characteristics of blockchain application
four characteristics of blockchain application:
first, decentralization: blockchain consists of many nodes to form an end-to-end network, and there is no centralized equipment and management organization
Second, tamper proof: the modification of the database by a single node or even multiple nodes cannot affect the database of other nodes, unless more than 51% of the nodes in the whole network can be controlled to modify at the same time, which is almost impossible
Third, transaction transparency: the operation rules of the blockchain are open and transparent, and all the data information is also open, Each transaction is visible to all nodes
4. Traceability: each transaction in the blockchain is connected with two adjacent blocks by password method, so it can trace back to the origin and development of any transaction.
