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







2. The existing conditions can't handle such a large-scale liquidation, but with the blockchain system, the confirmation of the right of each transaction is fixed. The liquidation only needs to be carried out according to the existing results, and there is no need for review. A lot of manpower and material resources are saved in the process, and the speed of liquidation will certainly be greatly increased, which is determined by the non tamperable characteristics of the blockchain, For example, Nanjing Rongze has a similar block chain inclusive financial platform.

Python learning path

the first stage is Python foundation and Linux database. This is the beginning stage of python, and also an important stage to help students lay a good foundation. You need to master Python basic syntax rules and variables, logic control, built-in data structure, file operation, advanced functions, moles, common standard library moles, functions, exception handling, MySQL use, coroutine and other knowledge points

learning objectives: master basic Python syntax and basic programming ability; Master the basic operation commands of Linux, master the advanced content of MySQL, and complete the projects of bank ATM system, English Chinese dictionary, lyrics parser, etc

the second stage is full web stack. In this part, you need to master HTML, CSS, JavaScript, jQuery, bootstrap, web development foundation, Vue, flag views, flag template, database operation, flag configuration and other knowledge

learning objectives: master the web front-end technology content, master the web back-end framework, skillfully use flash, tornado, Django, and complete the data monitoring background project

The third stage is data analysis + artificial intelligence. This part is mainly to learn the knowledge points related to crawler. You need to master the knowledge of data capture, data extraction, data storage, crawler concurrency, dynamic web page capture, scrapy framework, distributed crawler, crawler attack and defense, data structure, algorithm, etc

learning objective: to master crawler, data acquisition, data organization and algorithm advanced and artificial intelligence technology. It can complete crawler attack and defense, image mosaic, movie recommendation system, earthquake prediction, artificial intelligence project and other stage projects

The fourth stage is advanced. This is a python advanced knowledge point. You need to learn project development process, deployment, high concurrency, performance tuning, go language foundation, blockchain introction, etc

learning objectives: master the technology of automatic operation and maintenance and blockchain development, and complete the automatic operation and maintenance projects, blockchain and other projects

according to the python learning roadmap above, you can basically become a qualified Python development engineer. Of course, if you want to quickly become the elite talents of enterprises, you need good teachers to guide you, and you need more projects to accumulate practical experience

self learning itself is very difficult, and learning step by step is sure to be comprehensive and solid. If you want to learn which part, you can skip the targeted learning mole you don't need for the time being, and watch more different videos. Systematic learning usually takes 5-6 months

4. 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.
5. Although each traceability system uses the same blockchain technology, each traceability system is different in terms of proct positioning, underlying protocol selection, R & D and operation. The TAC traceability chain is jointly built by the former fast shot IOT technology team of the new third board company and Zhigui technology. Zhigui technology is responsible for the construction of the bottom layer of the blockchain and the block link layer. The TAC team is mainly responsible for the implementation of application scenarios, and transplants the traditional traceability system to the TAC system.
6. The QR code traceability system starts the standardized management from the source of the proct, and the proct is displayed in the QR code from the place of proction. The QR code traceability system can trace back the whole proction process and find the control point of the problem. Our company has made a traceability system, so we don't have to worry about many problems. We can learn about the tongtiao center, and their system is still good
7. The traditional traceability system either uses today's centralized account book model, or records and preserves by various market participants in a decentralized and isolated way, which is an information island model. In the centralized ledger model, who is the center to maintain the ledger becomes the key to the problem. Whether it is the source enterprise or the channel business, because they are all stakeholders in the circulation chain, when the account information is not concive to themselves, they are likely to choose to tamper with the account or falsely claim that the account information is lost e to technical reasons.
