Blockchain traceability Conference

1. There are two key characteristics in blockchain Technology: decentralization and tamper proof. This avoids the possibility of counterfeiting technically
for example, the vonetracer traceability system of wangchain technology will upload all links of a commodity to the blockchain, and users can scan the QR code to know all the information of the commodity. Agricultural procts enterprises can avoid the possibility of counterfeiting by using this technology.

2. After all, this year's blockchain fire, so these big guys are sure to participate. In terms of anti-counterfeiting traceability, the use of blockchain technology can be very good. Compared with our current anti-counterfeiting technology, blockchain technology is more suitable. Do anti-counterfeiting traceability is not much, such as "DITO traceability chain" is.

From the farm to the dining table, blockchain Traceability Technology is equivalent to buying a liability insurance for the proct

bathing crab and clenbuterol. In recent years, there have been food with white cubes (formaldehyde sodium bisulfite), poultry feeding hormone, flour with whitening agent, seafood soaked in formaldehyde, etc. in the market, there are more ripening agents and expanding agents sprayed on fruits, Spraying highly toxic pesticides on green vegetables makes people feel discolored. Food safety and health are becoming more and more important to us. Therefore, the blockchain Traceability Technology - a technology that can trace all agricultural procts from planting to selling has emerged

before making clear the Traceability Technology of blockchain, we should first make clear the difference between "traceability" and "traceability"

"traceability" includes logistics tracing and origin tracing. People often regard traceability and traceability as the same thing. In fact, what enterprises care about is tracing (don't lose the goods), and what consumers care about is tracing (whether the goods I bought are safe or not)
traceability is the most important feature of sanqingliangtian, which is a powerful means to ensure food safety. It starts from the source of planting, and controls the source, proction and processing, cleaning and disinfection, sub packaging, packaging, storage, transportation, sales, etc

in a word, to be exact, food traceability is a cost and an essential early investment, which is equivalent to purchasing a "liability insurance" for your proct. Maybe you can't see the effect in a year or two. When you really use it, it may be the straw to save your life

4. 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.

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. Blockchain can be traced. This technology is used in many fields. Many enterprises will use this technology to detect the source of goods, so that consumers can rest assured
the information in the blockchain can not be tampered, that is to say, the information recorded on the blockchain can be used to achieve the goal of traceability as long as the source is correct
in general, this technology is mostly used for commodity traceability, and the blockchain traceability technology can be understood in cryptography.

- yinlian answer:

blockchain can realize the traceability and non tampering of data, because it is based on the distributed database established by cryptographic links, thus forming non tamperable data sources. Therefore, in the whole process of procts from proction to circulation, complete information records can be achieved, and comprehensive data information can be provided for regulatory authorities, so that they can more efficiently complete proct quality inspection and data interconnection and sharing. In this process, blockchain can solve four problems:

first, information can not be tampered, consensus can be reached and trust can be built. In the network node composed of each participant, data records are formed in the business process, and the information of proct logistics, warehousing and proction, including raw material source, processing and assembly, is stored in the blockchain network to provide data information of each link for regulatory departments, cooperative enterprises or institutions

Second, the process is open and transparent. In the process of business process, the proct's anti-counterfeiting and circulation can be realized by implanting an identification chip into the proct and registering it on the blockchain, so that it can have a digital identity, and then record all the information of the digital identity, such as source and flow, through the account book maintained jointly, so as to achieve the verification effect

Third, save cost and improve efficiency. Under the condition of confidentiality, the data records on the blockchain are stored, transmitted, verified and analyzed by the regulatory department, and transferred among different departments, so as to achieve unified voucher, whole process record and enterprise credit reference, which can effectively solve the problems of multi-party participation, information fragmentation and repeated audit in circulation

Fourthly, information sharing. The circulation of enterprise proct certification depends on the interconnection of public data resources among departments and institutions such as commerce, customs, quality inspection, instry and commerce, banking, etc. under the review environment of blockchain construction, all departments can obtain information synchronously, establish credit evaluation mechanism based on supply chain, and organically connect various supply chain platforms, so as to improve the credit rating, credit record, risk warning, risk management, etc Information disclosure and sharing of illegal and dishonest behavior

the disadvantages of traditional anti-counterfeiting traceability are very obvious, and anti-counterfeiting traceability has always been an important scenario in blockchain application, such as yinlian, which also starts from the anti-counterfeiting traceability scenario, hoping to build a commercial blockchain

compared with the traditional centralized anti-counterfeiting Traceability Technology, yinlian uses the underlying technology of blockchain, and the merchants proce their own anti-counterfeiting codes to remove the trust problem of cheating by the intermediate anti-counterfeiting merchants. The main process is as follows:

8.

Traceability is one of the important application scenarios of blockchain technology. For consumers, food safety is a matter of life and health, so we now have higher and higher requirements for the quality of food. Due to its non tamperability, blockchain technology can record the whole life cycle process of food in the whole process, which can make us eat more at ease

What are the blockchain technology traceability platforms in Cheng? Xiaobian collects the following information from Cheng's blockchain traceability platform: xtrace

according to the official website of LianBo technology, the proct has reached cooperation with Boshi quality control traceability. The project is a quality traceability system initiated by the provincial food quality and safety collaborative innovation center of Xihua University. LianBo technology has added the bottom layer of blockchain to its original traceability system, making all traceability information tamperable, easy to locate, and improving the reliability and credibility of the traceability system. At present, the traceability system has been connected with famous upstream and downstream brands such as wudongfeng, Dancheng and Jixuan
