Blockchain traceability standards

1. Traditional authentication is easy to die out, easy to tamper, strong technology dependence and so on. The unique anti tamper, traceability, multi-party participation and other characteristics of blockchain technology are beneficial to avoid these problems
in the face of the growing demand for electronic data, the traditional way of certificate keeping graally reveals the shortcomings of high cost, poor convenience and low reliability. The blockchain has the characteristics of tamper proof, which can fix the electronic data when the data is generated. Blockchain technology has broad development prospects and wide application scenarios, and can be applied in more places in the future. Cipher finance mimacaijing captures blockchain information.

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. 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. 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. Cipher finance mimacaijing focuses on blockchain information.

5.

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

7. 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
