Principle of blockchain traceability anti counterfeiting technol

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

- yinlian answer:

blockchain can realize the traceability and non tampering of data, because it is based on the distributed database established by cryptographic links, thus forming non tamperable data sources. Therefore, in the whole process of procts from proction to circulation, complete information records can be achieved, and comprehensive data information can be provided for regulatory authorities, so that they can more efficiently complete proct quality inspection and data interconnection and sharing. In this process, blockchain can solve four problems:

first, information can not be tampered, consensus can be reached and trust can be built. In the network node composed of each participant, data records are formed in the business process, and the information of proct logistics, warehousing and proction, including raw material source, processing and assembly, is stored in the blockchain network to provide data information of each link for regulatory departments, cooperative enterprises or institutions

Second, the process is open and transparent. In the process of business process, the proct's anti-counterfeiting and circulation can be realized by implanting an identification chip into the proct and registering it on the blockchain, so that it can have a digital identity, and then record all the information of the digital identity, such as source and flow, through the account book maintained jointly, so as to achieve the verification effect

Third, save cost and improve efficiency. Under the condition of confidentiality, the data records on the blockchain are stored, transmitted, verified and analyzed by the regulatory department, and transferred among different departments, so as to achieve unified voucher, whole process record and enterprise credit reference, which can effectively solve the problems of multi-party participation, information fragmentation and repeated audit in circulation

Fourthly, information sharing. The circulation of enterprise proct certification depends on the interconnection of public data resources among departments and institutions such as commerce, customs, quality inspection, instry and commerce, banking, etc. under the review environment of blockchain construction, all departments can obtain information synchronously, establish credit evaluation mechanism based on supply chain, and organically connect various supply chain platforms, so as to improve the credit rating, credit record, risk warning, risk management, etc Information disclosure and sharing of illegal and dishonest behavior

the disadvantages of traditional anti-counterfeiting traceability are very obvious, and anti-counterfeiting traceability has always been an important scenario in blockchain application, such as yinlian, which also starts from the anti-counterfeiting traceability scenario, hoping to build a commercial blockchain

compared with the traditional centralized anti-counterfeiting Traceability Technology, yinlian uses the underlying technology of blockchain, and the merchants proce their own anti-counterfeiting codes to remove the trust problem of cheating by the intermediate anti-counterfeiting merchants. The main process is as follows:

3. Chongqing jinwowo: the blockchain can not be tampered with and the data can be traced, which can effectively solve the problem of traceability and anti-counterfeiting of goods
blockchain technology can also trace and prevent counterfeiting of drugs, artworks, collectibles, luxury goods, etc.

4. Chongqing jinwowo analysis: the function of non tampering and data traceability of blockchain can effectively solve the problem of traceability and anti-counterfeiting.

5. Compared with the past, various anti-counterfeiting technologies have been adopted in commodity traceability, but the results are not satisfactory. Using the traceability of blockchain technology, through the deep combination of logistics management, commodity anti-counterfeiting, commodity traceability, manufacturing management, instry collaboration and other fields, the traceability and security of commodities are increased.

6. 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.

7. Except for the minimum transaction amount

8. The blockchain traceability system can track and record the proction, processing, transportation, circulation, retail and other links of goods. The combination of the two characteristics of the blockchain data can not be tampered with and the transaction can be traced can eradicate the problem of fake and shoddy procts in the process of proct circulation in the supply chain, solve the trust problem existing in the traditional traceability, and protect the rights and interests of consumers. Cipher finance mimacaijing focuses on blockchain information.

9. The main thing is to ensure the traceability of food. Only by traceability, ensuring the safety of food source and clear source, and then through strict management of the processing process, can food safety be ensured

If the U.S. economy is dragged down by the epidemic, it will have an unprecedented adverse impact on the world economy, and may even lead to a significant retrogression of the global economy{ RRRRR}

3. If the U.S. economy is dragged down, the economic and trade impact on China, Japan and the European Union is fatal, and the trade systems of China, Japan and the European Union are almost all over the world. Therefore, if the U.S. economy collapses, it will directly lead to global economic disaster and crisis, and even lead to a significant retrogression of the global economy
