Anhui blockchain food traceability platform

1.

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. 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~~~

3. Anti counterfeiting research is the problem of "who am I?" it is to identify the unique properties of the goods by means of fingerprint recognition, iris recognition and other methods to ensure their authenticity and uniqueness. The problem of blockchain proct traceability is "where does the proct come from? Where are you going? " For example, vonetracer of wangchain technology, after users get the proct, they can scan the code to see the whole process.

4. 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

6. 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

What is blockchain? Blockchain is an important concept of bitcoin. It is essentially a decentralized database. At the same time, as the underlying technology of bitcoin, it is a series of data blocks generated by using cryptographic methods. Each data block contains a batch of information about network transactions of bitcoin, Used to verify the validity of its information (anti-counterfeiting) and generate the next block

and traceability blockchain is a technology based on the nature of blockchain, which is to improve people's quality of life and food safety. Now there are all kinds of traceability, from pig traceability, to dmtc's Agricultural traceability , and then to cosmetics traceability, which are all around this commodity closely related to our life

8. Direct network is enough. There are two ways to improve foraging skills: 1. Collect items in the field; 2. Chop trees with an axe. All the above actions can increase skill experience. When a certain amount of experience is reached, the skill level will be improved
