① Use blockchain to achieve full traceability of goods

Currently, the application of blockchain technology in new retail is mostly discussed in the supply chain - —That is, the full traceability of goods can be achieved through blockchain technology, thereby preventing counterfeit and shoddy goods, or when problems occur, the source of the problem can be quickly found. The basic framework for the application of blockchain technology in the supply chain (Figure 1) is that by using blockchain technology, we can solve the problem of consistency and traceability of the circulation of goods at different nodes in the supply chain. However, due to the It is a physical asset, which is different from virtual assets, so the digitization of goods needs to be realized first.

To achieve the digitization of physical assets, a lot of work needs to be done, and the authenticity of the on-chain needs to be ensured. Even in certain scenarios, the on-chain and off-chain need to be synchronized at all times. These are application areas. Costs and Difficulties of Blockchain Technology. One of the current feasible ways to solve this problem is to combine it with the Internet of Things. Specifically, it is to apply RFID technology to achieve the identification of goods and a certain degree of intelligence.

RFID technology has long been used to improve the transparency of the supply chain. Now combined with blockchain technology, it can ensure the transparency and security of mapping items from the physical world to the virtual world. Because blockchain technology can register the transfer of goods or commodities on the ledger as a transaction to determine the various participants, product origin, date, price, quality and other relevant information related to the management of the production chain. In addition, due to the decentralized structure of the ledger, it is impossible for any party to have ownership of the ledger or manipulate the data for personal gain. Furthermore, because transactions are encrypted and immutable, the digital ledger is difficult to compromise. Combining blockchain technology with RFID technology can not only combat counterfeit goods, but also improve customers' trust in the product supply chain.

On the one hand, whenever the custody of a product changes, products with RFID tags need to be scanned. Each scan will update the RFID chip and backend password, and capture and update geographic information in the system. On the other hand, when consumers purchase goods, they can scan the RFID tag with a smartphone equipped with an RFID reader to view the supply chain history to ensure that the product is genuine. When scanning, product information such as origin, manufacturer, appearance, and storage location changes will also be provided. Because each item carries a different RFID tag, which changes dynamically with updates and password changes in the supply chain, copying or counterfeiting is eliminated. Opening the product or removing the label renders the label unusable and therefore cannot be used for illegal purposes.

In addition, with the help of the Internet of Things, automatic uploading of data from various entities in the supply chain can be achieved. At the same time, blockchain technology and smart contracts are used to completely preserve the data of all entities in the entire supply chain, ensuring that the data is open, transparent, traceable and cannot be tampered with, making it easier to preventFalse traceability and supervision.

② What are the advantages of blockchain traceability compared with other traditional traceability models?

Traditional traceability systems generally use a centralized ledger model, which is dispersed and isolated by various market participants. Locally recorded and saved, it is an information island model. In the centralized ledger model, who maintains the ledger as the center becomes the key to the problem. Whether it is the source company or the channel provider, since they themselves are all stakeholders in the circulation chain, when the ledger information is not beneficial to themselves, At any time, you may choose to tamper with the ledger or falsely claim that the ledger information is lost due to technical reasons.
Under the information island model, each market participant maintains a ledger by himself. This ledger is commonly known as a ledger, and after being digitized, it was named the purchase, sale and inventory system. Whether it is a physical ledger or an electronic purchase, sale and inventory system, the owner can tamper with it or make it up at will. Blockchain's real-time reconciliation capabilities in registration and settlement scenarios, and its immutability and timestamp capabilities in data storage scenarios provide powerful tools for traceability, anti-counterfeiting, supply chain finance, and supply chain management scenarios.
Hongqiao Hi-Tech’s blockchain industry-specific application design uses the integrity and correlation of trusted transaction data to form a closed-loop self-certification capability for data on the chain. Used to verify the authenticity of digital documents and transaction records, and to track the origin of products and merchandise throughout the supply chain. This data proving product authenticity and origin is generally used by businesses and financial institutions in the assessment and processing of credit and loans.

③ What are the manifestations of commodity anti-counterfeiting and traceability in the application of blockchain technology

Chongqing Jinwowo Analysis: The first is the application of blockchain technology in commodity anti-counterfeiting and traceability.
Blockchain technology can be used to integrate information on the raw material process, production process, circulation process, and marketing process of goods and write them into the blockchain to achieve full-process authenticity traceability down to one item and one code. The information is unique and comes with the digital signature and timestamp of each subject for consumers to query and verify.

④ Traceability in blockchain application innovation for agricultural supply chain poverty alleviation refers to

Refers to a process of directional and non-directional tracking of end products produced in the supply chain .
Tracing has become the core of the agricultural supply chain poverty alleviation production plan, determining the success or failure of quality management, and playing a role in revitalizing rural agricultural development. Therefore, traceability in the agricultural supply chain poverty alleviation blockchain innovation is a kind of directional tracking process.
The core connotation of developing the agricultural industry chain and supply chain is to increase the average income of farmers, maximize agricultural development, achieve value-added efficiency, contribute to poverty alleviation, and have the effect of revitalizing the countryside.

⑤ How is the anti-counterfeiting traceability application of blockchain implemented?

The three major characteristics of blockchain are well known, which are decentralization, openness and transparency, and non-tampering. The non-tamperable feature enables blockchain to be used in many places. Such as product traceability, anti-counterfeiting, concealmentPrivacy protection, etc.

Because the production process it traces is all uploaded manually, so even if the data cannot be tampered with, the authenticity of the data cannot be guaranteed, and it still cannot be Solve substantive issues.

In general, although blockchain has brought great benefits, it is not perfect after all. However, blockchain technology has advanced the development of the times, and I believe its future is worth looking forward to.

⑥ What is the blockchain + product traceability solution?

In the heat wave of "embracing blockchain" in 2018, who can be the first to find application scenarios and launch implementation projects? , has become the most important part of competition.

Among them, traceability and anti-counterfeiting are considered to be one of the most promising areas for blockchain implementation, and it is also the first place where giants compete for the implementation of blockchain technology. fields. Domestically, cities such as Chongqing and Hangzhou have taken the lead in "testing" the application of blockchain in food traceability; e-commerce giants such as Tmall and JD.com are also using blockchain technology to trace the origin of goods and prevent counterfeiting in their respective systems.

Compared with traditional traceability and anti-counterfeiting, what are the advantages of blockchain traceability? What pain points can blockchain technology solve in the traceability and anti-counterfeiting business? Can blockchain technology open a new chapter in traceability and anti-counterfeiting business?
