Traceability blockchain
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
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. "
- 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:
The core technologies of Agricultural traceability blockchain are: one is the decentralized (distributed in the network), tamper proof and other features of blockchain to ensure the safety and reliability of data. The second is real-time through intelligent monitoring devices to directly communicate with nodes , store relevant data in nodes and broadcast to the whole chain , and the third is through radio frequency identification (RFID, things like two-dimensional code) and chips, Using the traceability of blockchain to establish traceability mechanism for agricultural procts
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 management2. 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
