Blockchain supply chain traceability

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. 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. "

3. When the supply chain meets the blockchain, the supply chain will become more transparent and large-scale collaboration will become easier. Improving supply chain traceability and security can make our economy safer and more reliable by promoting trust and honesty and preventing the implementation of problematic practices. In the future, jinwowo will focus on blockchain technology to promote the legal circulation and commercial application of big data.

- 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:

5. Compared with the past, various anti-counterfeiting technologies have been adopted in commodity traceability, but the results are not satisfactory. Using the traceability of blockchain technology, through the deep combination of logistics management, commodity anti-counterfeiting, commodity traceability, manufacturing management, instry collaboration and other fields, the traceability and security of commodities are increased. Cipher finance mimacaijing focuses on blockchain information.

6. Since the blockchain upsurge in China, the whole instry has been exploring various landing scenarios. It can be said that there are so many blockchains, which have attracted countless entrepreneurs. So what are the advantages of blockchain in the supply chain finance? What are the pain points of the traditional model? What new business models can blockchain create to solve these problems? How should blockchain start-ups enter this field
Moody's, the world's famous bond rating agency, has given 127 blockchain cases, from points to transaction clearing, from document storage to supply chain management, from cross-border payment to supply chain finance, and various applications emerge in endlessly
among so many applications, supply chain finance has attracted much attention, and its commercialization has made rapid progress
this is because, first of all, the supply chain finance scene has a trillion level market scale, and the ceiling is high enough. Secondly, this scene naturally needs multi-party cooperation, but there is no traditional centralized institution in governance, and it needs to use blockchain to build trust. At the same time, technically, this scene does not need high concurrency, and the current blockchain technology can meet it
1. Supply chain finance is a trillion level market
supply chain finance refers to the comprehensive financial procts and services provided to the upstream and downstream enterprises in the supply chain by taking the core enterprises and their related upstream and downstream enterprises as a whole, relying on the core enterprises, taking real trade as the premise, and using the method of self compensating trade financing
according to the different financing collateral, financial institutions divide the supply chain finance into accounts receivable, prepayment and inventory financing, among which the scale of accounts receivable is particularly large< According to the data from the National Bureau of statistics, at the end of 2016, the accounts receivable of China's Instrial Enterprises above designated size were 12.6 trillion yuan, an increase of 10% over the same period of last year, which generated a huge financing demand for enterprises. Compared with the huge accounts receivable, China's annual commercial factoring volume was only about 200 billion yuan in 2015. It can be seen that there is still a large number of supply chain demand has not been met, so the development space of supply chain finance instry is huge
2. How to solve the pain point of supply chain finance with blockchain
pain point 1: the financing of small and medium-sized enterprises in the supply chain is difficult and the cost is high
because banks rely on the ability to control goods and regulate sales of core enterprises, for the sake of risk control, banks are only willing to provide factoring services to upstream suppliers (limited to primary suppliers) with direct accounts payable obligations of core enterprises, Or provide advance payment or inventory financing to its downstream distributors (primary suppliers)
as a result, the demand of secondary and tertiary suppliers / distributors with huge financing demand can not be met, the business volume of supply chain finance is limited, and SMEs can not get timely financing, which will easily lead to proct quality problems and damage the whole supply chain system
blockchain solution:
we issue and run a kind of digital bill on the blockchain, which can be split and transferred freely in the case of transparency and multi-party witness
this model is equivalent to making the credit in the whole business system conctive and traceable, providing financing opportunities for a large number of SMEs that could not have been financed, greatly improving the efficiency and flexibility of bill circulation, and recing the capital cost of SMEs
according to statistics, in the past, traditional supply chain finance companies could only provide financing services for about 15% of suppliers (small and medium-sized enterprises) in the supply chain, while after adopting blockchain technology, 85% of suppliers could enjoy financing convenience
pain point 2: as the main financing tool of supply chain finance, the use of commercial bills and bank bills at this stage is limited, and the transfer is difficult
the use of commercial bills is subject to the reputation of enterprises, and it is difficult to control the arrival time of bank bill discount. At the same time, if we want to transfer these bonds, the difficulty is not small
because in the actual financial operation, banks are very concerned about the legal effect of "Notice of transfer" of accounts receivable claims. If the core enterprise cannot sign back, banks will not be willing to extend credit. It is understood that the bank is very cautious about the legal effect of signing the "Notice of assignment" of creditor's rights, and even requires the legal representative of the core enterprise to go to the bank to sign it face to face. Obviously, this way of operation is extremely difficult
blockchain solution:
an alliance chain can be built between banks and core enterprises, which can be used by all member enterprises in the supply chain. By using the characteristics of multi-party signature and tamper proof of blockchain, the transfer of creditor's rights can get multi-party consensus and rece the difficulty of operation
of course, the system design should be able to achieve the legal notice effect of bond transfer. At the same time, the bank can trace the transactions of each node and draw a visible transaction flow chart
pain point 3: it is difficult for the supply chain financial platform / core enterprise system to prove its innocence, resulting in high risk control cost of the capital side
in the current supply chain financial business, banks or other capital sides are concerned about the authenticity of the transaction information itself in addition to the repayment ability and willingness of the enterprise, and the transaction information is recorded by the ERP system of the core enterprise
although ERP tampering is difficult, it is not absolutely credible. Banks are still worried that core enterprises and suppliers / dealers collude to modify information, so they need to invest manpower and material resources to verify the authenticity of the transaction, which increases the additional cost of risk control
blockchain solution:
as a "trusted machine", blockchain has the characteristics of traceability, consensus and decentralization, and the data on the blockchain has a time stamp, so even if the data of a node is modified, it can not cover the sky. Therefore, blockchain can provide an absolutely trusted environment and rece the cost of risk control on the capital side, Solve the bank's doubts about being tampered with information
3. How should blockchain companies cut into supply chain finance
in terms of market choice, we believe that blockchain start-ups should choose the segments with high enough ceiling, such as household appliances, automobile, retail, clothing, pharmaceutical instry, etc. On the one hand, these instries have a broad market, on the other hand, their supply chain management infrastructure is relatively perfect, and the early cost of block chain is relatively small
we believe that there are two modes for blockchain companies to enter supply chain finance
the first is to directly cooperate with core enterprises / platforms to provide them with the underlying solutions of blockchain. After accumulating enough data, they can provide financial services to the investors by building alliance chain Alliance chain mode)
in view of the fact that the blockchain itself can not solve the problem of risk control, enterprise level risk control still needs to focus on strong core enterprises at the present stage. At the same time, obtaining the support of core enterprises can also effectively solve the problem of customer acquisition, because a large core enterprise generally has thousands of various suppliers
at present, domestic blockchain companies start from core enterprises, including Bubi and Wanglu technology. Bubi has launched an alliance chain "Bunuo" for supply chain finance, linking banks, core enterprises and factoring companies. Bunuo is based in Guangzhou and Shenzhen, radiating southeast business, and digging deep into the field of supply chain finance, Previously, it signed a strategic cooperation agreement with Yigang
the second mode is to provide supply chain management services, such as traceability, tracking, visualization, etc., to integrate information flow, logistics and capital flow, and then engage in financial services Private chain mode)
this mode is equivalent to building an application scenario with blockchain. Just like Alipay, if Ma Yun did Alipay directly, it would be difficult to do so because there was no application scenario, so Taobao first served the real economy. With Taobao, Alipay emerged as a centralization trust scenario and grafted other applications on Alipay before accomplishments.
at present, among the domestic blockchain companies, bitse and food premium are the ones that adopt the supply chain service mode
for example, vechain provides a method of anti-counterfeiting and traceability, by implanting an NFC chip into each commodity, registering the commodity on the blockchain, so that it has a digital identity, and then recording all the information of the digital identity through the account book maintained jointly, so as to achieve the verification effect. At present, vechain procts have been connected with more than 10 instry benchmark customers, and millions of IDS are running on the chain
4. Build a supply chain financial exchange in three steps
from the perspective of implementation path, the application of blockchain in the field of supply chain finance can be realized in three steps
as a prerequisite, we need to build a blockchain + supply chain finance alliance, whose participants include supply chain finance platform, core enterprises, professional financial intermediaries, financiers, factoring institutions, etc
each participant needs to undertake corresponding obligations. For example, the platform is responsible for providing basic services such as supply chain information and customer information, while the core enterprise understands the instry situation, has control over the enterprises in the supply chain, and is responsible for risk control
professional financial intermediaries can integrate and analyze the platform information, and provide customized supply chain financial procts, such as personalized blockchain electronic bills. The fund side includes banks, Internet financial institutions and other customers who are responsible for docking the corresponding risk preference
after the establishment of alliance chain, we can start the three-step strategy
the first step is to put the data in the supply chain alliance on the chain, use the characteristics of blockchain to make it tamperable, and provide services such as data authentication and traceability
the second step is asset digitization, which turns warehouse receipts, contracts, and blockchain bills that can represent financing needs into digital assets, which are unique, tamper proof, and non reprocible
the third step is the transaction of digital assets. The supply chain financial platform will be transformed into a financial asset exchange, which will transform the non-standard enterprise loan demand into standardized financial procts for token, docking investment and financing demand, and concting value trading
finally, blockchain technology will effectively enhance the liquidity of supply chain financial assets, mobilize new financing tools and risk control system, help cover the long tail market of SME financing, and promote supply chain finance as a service.

7. Dmtc mainly uses blockchain technology to integrate the resources of agricultural supply chain, combined with the support of soft and hard chain technology, so as to realize the whole process of agricultural organic food proction record, check, tamper proof and traceability, and thoroughly solve the practical problems of agricultural development. It includes data acquisition, data security and data sharing
in terms of data collection, through artificial intelligence and Internet of things technology, dmtc runs through the whole agricultural ecological chain. During agricultural proction, it automatically records the proction environment data, proction process data, transportation, sales and consumer behavior data of agricultural procts

in terms of data security, the existing traceability IT architecture is used to maintain the security of the system through network equipment and Agricultural Internet of things (IOA)
in terms of data sharing, the data collected in the whole process of dmtc can be conditionally shared with users in the whole supply chain of ecological agriculture, and the proction and transportation data can be shared with consumers, so as to trace the origin and development of procts, guide agricultural procers to adjust proction direction and improve proction efficiency.

8. Jinwowo blockchain technology can store real-time and effective data of all links in the supply chain from top to bottom, and its data entry is not controlled by a Qiye company. And from proction to every link is traceable

9. The traceability system of the traditional mode either uses today's centralized account book mode, or is separately recorded and kept by various market participants. It is an information island mode. In the traditional mode, each market participant maintains an account book by himself, but no matter it is an entity account book or an electronic purchase and sales position system, The owner can tamper or fabricate after the event at will. Eventually, accountability cannot be traced quickly

jinwowo blockchain technology is the internal logic of applying blockchain technology to traceability, anti-counterfeiting, and optimization of supply chain. The core technology of blockchain is decentralization, real-time reconciliation ability in registration and settlement scenarios, and tamper proof and time stamping in data storage scenarios. For traceability, anti-counterfeiting, supply chain scenarios to provide a strong guarantee.

10. Blockchain provides an excellent opportunity for traceability business. Traceability refers to tracking and recording the circulation chain of tangible goods or digital goods. Through the registration of each circulation, it can achieve the goals of information collection and recording from the source, tracing the source of raw materials, proction process, inspection batch, logistics circulation, anti-counterfeiting authentication, optimizing the supply chain according to the traceability information, and providing supply chain financial services. The internal logic of applying blockchain technology to traceability, anti-counterfeiting and optimization of supply chain is very similar to the scenario of data storage, that is, data can not be tampered with and time stamped.
