What needs to be done before blockchain traceability
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
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
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
in the future, the commodity traceability service instry will continue to develop in the direction of globalization and digitization, and more enterprises will certainly join this field and build corresponding traceability system based on their own needs
traceability chain applies blockchain technology to build public chain and realize cross chain interaction, which can be said to be forward-looking in strategic layout.
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. "
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.
