Traceability Technology of blockchain products

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.

The three characteristics of blockchain are well known, that is, decentralization, transparency and non tampering. The tamper proof feature makes blockchain used in many places. Such as proct traceability, privacy protection and so on

because the proction process it traces back to is artificially uploaded, so even if it is tamperable data, the authenticity of the data can not be guaranteed, and the substantive problem still can not be solved

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

3. Let's take vonetracer, the blockchain traceability platform of wangchain technology, as an example. Blockchain technology can record all links such as proct planting, factory manufacturing, logistics transportation, warehousing and sales on the chain. After users get the proct, they can scan the QR code to see the traceability of the proct.

4. With the help of blockchain technology and alliance chain node, wangchain technology integrates and writes the information of commodity raw material circulation process, proction process, commodity circulation process and marketing process into the blockchain, and uses the tamper proof attribute of the blockchain to realize the whole process traceability of one thing one code

5.

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

6. Blockchain can be traced. This technology is used in many fields. Many enterprises will use this technology to detect the source of goods, so that consumers can rest assured
the information in the blockchain can not be tampered, that is to say, the information recorded on the blockchain can be used to achieve the goal of traceability as long as the source is correct
in general, this technology is mostly used for commodity traceability, and the blockchain traceability technology can be understood in cryptography.

7. Anti counterfeiting traceability through the traditional two-dimensional code technology has been able to solve the problem, the pain is that the anti-counterfeiting data stored in the central structure, easy to tamper with, credibility is not strong. It happens that the characteristics of blockchain are very consistent with anti-counterfeiting traceability. Let's review the four characteristics of blockchain application
four characteristics of blockchain application:
first, decentralization: blockchain consists of many nodes to form an end-to-end network, and there is no centralized equipment and management organization
Second, tamper proof: the modification of the database by a single node or even multiple nodes cannot affect the database of other nodes, unless more than 51% of the nodes in the whole network can be controlled to modify at the same time, which is almost impossible
Third, transaction transparency: the operation rules of the blockchain are open and transparent, and all the data information is also open, Each transaction is visible to all nodes
4. Traceability: each transaction in the blockchain is connected with two adjacent blocks by password method, so it can trace back to the origin and development of any transaction.

8. 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.
