Blockchain acquisition and monitoring system

1. Lifechain has developed the mall lifex based on blockchain health detection equipment, which is embedded in the preset application of lifechain. The collected health data is automatically uploaded by using smart contract. Lifechain will automatically match the corresponding KB to the collector. Investors can purchase and lay such medical equipment to collect a large amount of health data.

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

3. New technology is born to overthrow tradition! The law of human competition! Traditional instries do not realize how to start transformation! Of course, transformation is as painful as cutting meat

4. It depends on whether you invest. If you don't invest, you can make money by checking in every day. If you invest in the miner, the income will be higher.

5. In fact, both gikee and search are tools for monitoring data on the chain, and they are also tools for searching Eth and erc20. However, there are many differences between the two. The biggest difference is that gikee is the world's first app, and search is the PC end. In addition, as the app end, gikee has change reminder, which can receive information reminder on the chain in real time. So, I think, relatively speaking, gikee is more convenient.

6. It is combined with environmental blockchain

7. I saw an agricultural traceability project of dmtc rice before -

is to install an RFID chip on the proct, which records the whole life cycle of the proct, which is equivalent to that every commodity has an identity tag. These data will be linked in real time and form a tamperable information to ensure the safety and traceability of goods
my understanding is probably like this, so should other traceability procts
you can also ask me if you have any questions, I hope it will help you!
