A. What is blockchain anti-counterfeiting technology?

Blockchain anti-counterfeiting technology is a new type of anti-counterfeiting technology used to solve the problem of counterfeiting during the circulation of goods. The problem of shoddy products. This technology uses a distributed ledger to record and trace the entire process of production, circulation, and sales of goods, and stores the records on the blockchain. Due to the decentralization, non-tampering, and transparency of the blockchain, the authenticity and credibility of the records are guaranteed.
The application of blockchain anti-counterfeiting technology can effectively prevent the circulation of counterfeit and shoddy goods, protect the rights and interests of consumers, and promote the improvement of product quality and the healthy development of the industry. In the fields of food, medicine, luxury goods and other fields, blockchain anti-counterfeiting technology has been widely used. By scanning the Hupin QR code on the product, consumers can check the production, circulation, sales and other information of the product to ensure that they are purchasing authentic products.
At the same time, blockchain anti-counterfeiting technology can also improve the transparency and efficiency of the supply chain. Traditional supply chain management has problems such as information asymmetry and lack of trust, making it difficult to manage the information flow and capital flow of the supply chain. Blockchain anti-counterfeiting technology can solve these problems. By recording and tracing the shipping process of goods, it can realize the visualization, traceability and controllability of the supply chain, improve the transparency and efficiency of the supply chain, and reduce management costs and risk.
In short, blockchain anti-counterfeiting technology is an innovative anti-counterfeiting technology that can effectively prevent the circulation of counterfeit and shoddy goods, protect the rights and interests of consumers, promote the improvement of product quality and the healthy development of the industry, and can also improve supply. chain transparency and efficiency, contributing to the sustainable development of society.

B. What is blockchain traceability technology?

From farm to table, blockchain traceability technology is equivalent to purchasing a liability insurance for the product

Bath crab, clenbuterol In recent years, there have been reports on the market of food added with white lumps (sodium formaldehyde sulfoxylate), poultry feeding hormones, whitening agents added to flour, seafood soaked in formaldehyde, etc., and ripening agents and enlarging agents are sprayed on fruits. , spraying highly toxic pesticides on green vegetables, etc. have made people change their color after hearing it. Food safety and health are becoming more and more important to us, so at this time, blockchain traceability technology emerged - a technology that allows agricultural products to be traced from planting to to selling all traceable technology.

Before figuring out the blockchain traceability technology, we must first understand the difference between "traceability" and "traceability".

"Traceability" includes two meanings: logistics tracking and traceability. People often think of traceability and traceability as the same thing. In fact, what companies care about is tracking (don’t lose the goods), while consumers care about traceability (whether what I bought is safe).
The biggest feature of Sanqing Fertile Farm is its traceability, which is a powerful means to ensure food safety. It starts from the source of planting and controls the source, production and processing, cleaning and disinfection, sub-packaging, packaging, storage, transportation, sales and other links.

In short, to be precise, food traceability is a cost and a necessity.The indispensable initial investment is equivalent to purchasing a "liability insurance" for your product. Maybe you won't see the effect for a year or two, but when you really use it, it may be a life-saving straw.

C. With this certification (ant blockchain traceability), is it really authentic?

No, it can only prove that the product has a traceable identification (ID). If you assume All counterfeit and shoddy products cannot obtain this logo, so all genuine products have traceable IDs.

And the binding between a traceability logo and a product is not unique and unbreakable! The key is that the logo is on the block, but the product is not! In other words, a logo can also be used for counterfeiting. Increasing the difficulty of marking can raise the threshold for counterfeiting, but it cannot completely eliminate it!

Blockchain can only protect digital assets. If you want to protect commodities, the higher the social cost, the more difficult it will be to overcome it. Because commodity protection requires relevant social investment. In fact, the fact that this matter is attached to the concept of block chain is pure speculation! There are no block chains, and the classic technology stack has many solutions for traceability identification!

Is blockchain + anti-counterfeiting traceability necessary?

Blockchain is a new application of computer technology such as distributed data storage, point-to-point transmission, consensus mechanism, encryption algorithm, etc. It is a series of data blocks generated by using cryptographic methods. Each data block contains a change of hands. or transaction information.

It can be used in the food sector so that each party in the supply chain (producer, processor and distributor) can provide traceability information about their specific role (such as date, location, farm construction, distribution channels).

At present, among the many application fields of blockchain, blockchain food traceability and anti-counterfeiting is currently one of the most promising blockchain fields.

The reasons can be summarized in three aspects:

First, for consumers, this technology will meet their growing demand for food quality transparency;

< p>The second is that for food suppliers (breeders), this is a means to demonstrate the high quality and professionalism of their products;

The third is that the technology is easy to promote and use, and the outer packaging of each product Each will include a QR code that consumers can scan using their smartphones, eliminating the need to purchase additional equipment.

D. What are the advantages of using blockchain technology in anti-counterfeiting and traceability of goods?

In the early days of the “blockchain era”, people’s understanding of blockchain was limited to digital Currency and currency speculation operations. With the development of technology, people realize that applying blockchain technology to industries and promoting the economic development of the industry is its true value. Blockchain traceability and anti-counterfeiting is considered to be one of the most promising areas for blockchain implementation, and it is also one of the first areas where giants compete for the implementation of blockchain application technology. It can be said that whoever can launch the first implementation project will be one step ahead in the industry.
Will useBlockchain technology integrates and writes information on the commodity raw material circulation process, production process, commodity circulation process, and marketing process into the blockchain to achieve one-item, one-code, full-process authenticity traceability. Blockchain technology is used to digitize the information of participants in different commodity circulation and store it in the blockchain. These include origins, manufacturers, distributors, retailers, brands and consumers. Make each participant's information viewable in the blockchain.
With the help of blockchain technology, the information of all aspects of the goods from production to warehousing is integrated and written into the blockchain. Each piece of information has an independent and special blockchain ID, accompanied by the digital signature and digital signature of the goods. Timestamps provide users with good underlying data support and product quality control.
At the consumer level, through terminal traceability QR codes and open and transparent blockchain technology support, users can easily check the authenticity of products, cultivate users' awareness of authenticity, and enhance brand value.
Due to the complex and difficult-to-verify transaction content and the temptation of high profits, counterfeiting and selling of counterfeit products are frequently prohibited in the market. This not only affects the shopping experience of consumers, but also damages the brand image of merchants. For merchants and consumers, it is urgent to establish a credible anti-counterfeiting traceability system.
All commodity transactions in the entire market must be supported by a trustworthy anti-counterfeiting traceability mechanism. In this way, we can better ensure the quality of the company's own products and improve consumers' shopping experience.

E. 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.

F. How blockchain agriculture can make every link of agricultural products transparent and traceable

It can provide consumers with origin information and make people more assured.

G. 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, blockchain technology can be used to realize the full traceability of goods, thereby preventing counterfeit and shoddy goods, or when problems arise, 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 realize 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 allThe costs and difficulties of applying 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, which facilitates anti-counterfeiting, traceability and supervision.

H. 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-tamperability. . The non-tamperable feature enables blockchain to be used in many places. Such as product traceability, anti-counterfeiting, privacy 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.
