Using 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 inferior 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 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 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.

㈡ 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, 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.

㈢ What is the difference between blockchain product traceability and product anti-counterfeiting

The two have different meanings
Product anti-counterfeiting is to identify the authenticity of goods and prevent counterfeiting. Product traceability uses blockchain technology to check the source information of goods. Crypto Finance focuses on blockchain information.

㈣ What is blockchain traceability technology

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

Bathing crabs, 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. In addition, fruits are sprayed with ripening agents and enlarging agents. Spraying highly toxic pesticides on green vegetables has made people change their color after hearing it. Food safety and health are becoming more and more important to us, so this is when blockchain traceability technology emerged - a technology that allows agricultural products to be traced from planting to Fully traceable technology for sale.

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 an essential initial investment, which 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.

㈤ IBM Walmart applies blockchain technology to prescription drug tracking

IBM, KPMG, Merck and Walmart are joining forces with the FDA to create a proof-of-concept blockchain network. The project, which is tied to the U.S. Drug Supply Chain Security Act, is designed to help the FDA and other organizations in the drug supply chain develop a blockchain network to identify and track drug shipments.Distribution of prescriptions.

As the blockchain famous saying goes: it builds trust when you need it most! IBM's global solutions leader Mark Treschuk said that blockchain can provide an important new method to further improve trust in the biopharmaceutical supply chain. Blockchain technology can not only provide an audit trail to track drugs in the supply chain, but also track who shares data and who shares it with whom, without revealing the contents of the data itself. Blockchain therefore has the potential to change the way drug data is controlled, managed, shared and acted upon throughout its lifecycle.

IBM has been committed to the research and development of blockchain technology in recent years, and has been applied in fields such as shipping, food, banking and hard drives. In 2016, Walmart partnered with IBM to apply new food safety to its suppliers, applying blockchain technology to achieve traceability throughout the food supply chain. In addition, IBM and Maersk have formed a joint venture focusing on global trade, aiming to create a blockchain platform to serve trading partners around the world.

China is also establishing new standards for food supply chain safety, relying on the eyes of IBM, Walmart, JD.com and Tsinghua University to use blockchain technology to collect data on the origin, safety and authenticity of food.

The widespread application of blockchain technology will change people’s lives. From wearables to food, it changes people’s understanding of ordinary things. After applying blockchain, ordinary items will be redefined, and consumed items will not disappear out of thin air. Blockchain technology will make a world defined by matter. , truly becomes a digital world, and every seed that disappears on the earth will be remembered forever!

㈥ What are the advantages of the application of 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 currencies. 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.
With the help of blockchain technology, information on the circulation process of commodity raw materials, production process, commodity circulation process, and marketing process will be integrated and written 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. timestamp, forProvide 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.
