Blockchain for traceability
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.
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
- 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 behaviorthe 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:
2 walk about 180 meters from Guangzhou electronic information school to Tongxin south station, take bus 278 (take 8 stops) to Shipai village station, then transfer to bus 506 a (take 36 stops), bus 506 (take 37 stops) to Luogang Dalong village station. Cross the road and walk about 200 meters to the left to Guangzhou International Sports Performing Arts Center
3 walk about 180 meters from Guangzhou electronic information school to Tongxin south station, take bus No. 189 (take 1 station) to Xiaobei station 1, go ahead to entrance / exit b of Xiaobei station, and then take Metro Line 5 (take 18 stations) to entrance / exit a of Wenchong station. Take about 40 meters to Wenchong market station, transfer to Y11 Road (take 8 stops) and get off at Guangzhou International Sports Performing Arts Center terminus
Tianhe passenger station terminus, transfer to Y12 Asian Games special line (take 17 stops) and get off at Guangzhou International Sports Performing Arts Center terminus. Walk about 70 meters to Guangzhou International Sports Performing Arts Center
technology has two key characteristics:
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.
