Agricultural blockchain bulk commodity trading system

1. There are many different trading systems, different functions, different systems, and different recipes, so it's hard to say about the development cost
for specific development enterprises, such as Yingtang Zhongchuang, the development of serious blockchain trading system, the cost of such system development is certainly higher than those who exaggerate. No matter what you want to develop, you have to hold a requirements meeting to determine the specific development content, so as to get the actual answer.

2. It can provide information of procing area for consumers and make people feel more at ease.

3. Aichichain wallet allows indivials or companies to issue their own digital assets. For each asset issued, a certain amount of TCC needs to be handed over to the system. All the paid TCCS will return to the public mine pool and be distributed to each node of the maintenance system through dpos.

4. There must be a concept of MLM. After a visit to a round table, I felt warm and concerned. I applied for a class in Japan and was asked to pay 16500 RMB on the spot. It was in mid October of 17. At the beginning of the 19th century, I suddenly remembered that there was something else. For more than a year, no one told me to attend class. I called my contact person and said that someone contacted me in September of 18, but I didn't get in touch. There is a big difference between the urgency of marketing and the carelessness of payment. They decided to ask for a refund and coordinated for many times. At the end of February, they finally got a refund, only 11550, 70%.

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

Anti counterfeiting traceability system refers to the use of two-dimensional code anti-counterfeiting label information storage encryption features to keep the commodity information confidential, refine the proction process to each key control point, clarify the responsibilities of each key link, and complete the safety and quality management mode of "proction records, process traces". After scanning the QR code, consumers can get the date of proction, place of proction, commodity information, etc., so as to complete the traceability of goods. Two dimensional code anti-counterfeiting traceability system can not only let consumers buy at ease, but also deal with the problem of anti-counterfeiting traceability for businesses

The fourth step is flow detection. Enterprises should input the information of proct logistics management, sub packaging sales and proct warehousing, so as to realize the management mode of responsibility to person

The fifth step is terminal sales. Note the procts put into different sales channels, which is convenient for enterprises to view the performance of different marketing channels

the sixth step is to query the terminal. Consumers can query through four ways: mobile phone query, Internet query, 400 query, query and query

7. Bulk commodity trading, such as crude oil trading, has many disadvantages in the traditional trading mode, such as high transaction cost and complex process. Therefore, the decentralized, transparent and open characteristics of blockchain technology can simplify the process of crude oil trading. Zhong An is also involved in this field. It seems that the feeling is awesome.

8. Dmtc mainly uses blockchain technology to integrate the resources of agricultural supply chain, combined with the support of soft and hard chain technology, so as to realize the whole process of agricultural organic food proction record, check, tamper proof and traceability, and thoroughly solve the practical problems of agricultural development. It includes data acquisition, data security and data sharing
in terms of data collection, through artificial intelligence and Internet of things technology, dmtc runs through the whole agricultural ecological chain. During agricultural proction, it automatically records the proction environment data, proction process data, transportation, sales and consumer behavior data of agricultural procts

in terms of data security, the existing traceability IT architecture is used to maintain the security of the system through network equipment and Agricultural Internet of things (IOA)
in terms of data sharing, the data collected in the whole process of dmtc can be conditionally shared with users in the whole supply chain of ecological agriculture, and the proction and transportation data can be shared with consumers, so as to trace the origin and development of procts, guide agricultural procers to adjust proction direction and improve proction efficiency.
