How to trace the source of blockchain products

1.

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

2. 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.

3. 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

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

5. I was engaged in this instry in Shanghai before, and changed to another instry e to personal reasons. The blockchain technology itself has no traceability ability. It must use some other methods to obtain information and upload the information to the blockchain ledger to achieve the purpose of traceability. For specific operation methods, please refer to the official website of akte for more information. Thank you~~~

6. Chongqing jinwowo analysis: the first is the application of blockchain technology in commodity anti-counterfeiting traceability
with the help of blockchain technology, the information of commodity raw material process, proction process, circulation process and marketing process can be integrated and written into the blockchain, so as to realize the whole process of authentic proct traceability from one thing to one code. Each information is unique, and is attached with the digital signature and time stamp of each subject for consumers to query and verify.

7. There are two key characteristics in blockchain Technology: decentralization and tamper proof. This avoids the possibility of counterfeiting technically. For example, the vonetracer traceability system of wangchain technology will upload all links of a commodity to the blockchain. Users can scan the QR code to know all the information of the commodity. Agricultural procts enterprises use this technology to avoid the possibility of counterfeiting.

A: first, the connotation of blockchain

blockchain is a distributed shared ledger and database, which is decentralized, tamper proof, traceable, collective maintenance, open and transparent

Agricultural traceability is the most complex and difficult part of food traceability. At present, there is no complete agricultural proct traceability system based on food safety proction and whole process supply chain management

2. The most important part of the construction of agricultural traceability system is "one center and three moles", which is a traceability cloud data center and three moles of procers, regulators and consumers

Third, composition of blockchain

blockchain system is composed of data layer, network layer, consensus layer, incentive layer, contract layer and application layer

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.
