Blockchain traceability open source project
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.
after entering the research of Ethereum, I wanted to start from the underlying source code at the beginning, but the whole process was rather difficult. After re analyzing our requirements, I felt that we could develop to some extent and meet some needs by using its existing interface, so I translated the comments of the source code, basically understood the role of each mole, and no further modification was needed, After all, Ethereum is also a project that took dozens of big bulls a long time to build.
it is very difficult for us to successfully transform it into what we want in a period of time. The faster, the easier, the better
and there is a very important problem. If Ethereum is changed, it will not be able to connect to its public network and use the second largest amount of computing power in the world. This is a matter of putting the cart before the horse. It seems that the answer is wrong, but the main expression is that if the subject wants to do development, it is enough to carefully analyze a project,
after all, the logic is almost the same. We should learn more about blockchain and pay attention to ATV
Traceability is one of the important application scenarios of blockchain technology. For consumers, food safety is a matter of life and health, so we now have higher and higher requirements for the quality of food. Due to its non tamperability, blockchain technology can record the whole life cycle process of food in the whole process, which can make us eat more at ease
What are the blockchain technology traceability platforms in Cheng? Xiaobian collects the following information from Cheng's blockchain traceability platform: xtrace
according to the official website of LianBo technology, the proct has reached cooperation with Boshi quality control traceability. The project is a quality traceability system initiated by the provincial food quality and safety collaborative innovation center of Xihua University. LianBo technology has added the bottom layer of blockchain to its original traceability system, making all traceability information tamperable, easy to locate, and improving the reliability and credibility of the traceability system. At present, the traceability system has been connected with famous upstream and downstream brands such as wudongfeng, Dancheng and Jixuan

xinlianzhenpin of China Network Security
xinlianzhenpin launched by China Network Security united insurance company, testing company and e-commerce platform has been applied in Cheng kiwi fruit, ChouJu and other agricultural procts, providing reliable traceability services for high-quality agricultural procts
Sichuan rundi's fertilizer traceability
Sichuan Zhenxuan traceability
Sichuan Zhenxuan traceability makes full use of the combination of Internet technology and ecological agriculture, through the construction of proct base Internet online, in order to break the traditional concept of agricultural sales, consumers can fully understand the whole proction process
so the blockchain traceability platform in Cheng is about these. I believe blockchain traceability can develop better and better
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 management2. 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
blockchain
technology independently developed by wangchain technology, which is different from the traditional one. Instead, vonetracer uses
blockchain technology
to realize the real traceability of food and increase trust for traceability. After the verified proct information is linked, the data on the chain is backed up in each
network node
, As a result, the cost of data modification in the whole network is very high, which ensures that the data in the blockchain network is difficult to be tampered with, and the data can be checked and trusted, so as to truly realize the source quality control of agricultural procts.
