Agricultural blockchain Enterprises

1. First of all, I'd like to introce some well-known blockchain companies in China, and then I'll personally evaluate which one is good. You can judge for yourself

1. Bubi blockchain company, which is engaged in the underlying technical services and instry solutions of blockchain. That is to say, an underlying blockchain is built, and an adaptation layer is built on it, so that enterprises can quickly establish commercial applications. The underlying blockchain is self-developed. The consensus mechanism is pbft, TPS is 5000 transactions per second, UnionPay is 2000 transactions per second, and bitcoin is 7 transactions per second. Of course, different underlying architectures lead to different performance, because Bubi's commercial blockchain pays more attention to performance. At present, Bubi is mainly used in digital assets, supply chain finance, supply chain traceability, public notary and other fields< 2. Bumeng blockchain. Theoretically, bumeng should be regarded as the proct line of Bubi, but Bubi is mainly engaged in the private chain, while bumeng is an alliance chain. So separately, bumeng is Bubi's layout in digital assets. The underlying technology is Bubi blockchain, but it encapsulates the blockchain according to the scene and provides API interface for enterprises. Enterprises issue their own assets on it. According to the characteristics of blockchain, they can freely circulate their assets. At present, some enterprises such as sunshine insurance, Qianxiang finance, crowdsourcing, Haohuo, etc. have joined in, and the assets in them include insurance policies, integral points, and so on Financial procts and so on. Finally, it is estimated that this platform will break through the barriers between assets, and the end users can freely use and transfer these assets. This is an interesting way for the blockchain instry, because it has both the opening of public chain and the security of private chain

Third, only chain, which is a commodity ID management cloud platform based on blockchain technology, provides enterprise users with commodity asset management, tracing, anti-counterfeiting verification, new supply chain management, etc. in the form of baas. Simple understanding is that only chain has done the content of "supply chain traceability" of Bubi blockchain

four, concentric mutual aid, concentric mutual aid is a mutual aid security platform, put some mutual insurance related information into the blockchain, and users can apply to become nodes, participate in bookkeeping, and maintain their own data

5. Xiaoyi is a decentralized network protocol based on blockchain technology, which digitizes the assets and interests of the real world, and carries out financial business such as registration and issuance, transfer transaction, clearing and delivery through point-to-point network

these five blockchain companies are probably well-known in China, and I personally recommend bumeng

first, bumeng uses the underlying technology of Bubi blockchain, which is very promising in the instry. It has the largest number of landing applications in China. Enterprises can not only use the blockchain technology at low cost (just call the interface, it seems that it is free), but also use the resources inside. Think about being on the same chain with many enterprises and docking resources in the future, User transformation should not be easy

Second, Weilian and Tongxin Huzhu focus on one field, and do not provide underlying technology and instry solutions. That is to say, if you are in this instry or can be used in the upstream and downstream of this instry, you can not be used in other fields. Take mutual security field as an example, zhongtuobang and zebra Club both choose bumeng. Of course, if it is an investment, you can consider it

Third, Xiaoyi, why not recommend Xiaoyi, because Xiaoyi is an open source project, and we all know the domestic business environment, especially when the instry is just beginning to develop, and the domestic market is different from that of foreign countries, Xiaoyi has gone through two rounds of ICO, which will be a great worry in the future operation, and at present, Xiaoyi has not been applied in practice, We have made a Fada platform, which has not been used by any company yet (guess it may be related to the factors of open source, who dares to open their data completely). Of course, the open attitude of Xiaoyi is worth encouraging. Although I guess the advantages and disadvantages of the code are well understood by peers, it is not clear

Fourth, why is there no recommendation for Bubby? Bubby has raised 30 million yuan a while ago, because Bubby is more open and has more resources. Of course, if the business requires high privacy, it can also choose Bubby blockchain

finally, for all my hard work, choose me!

2. Introction: the the Great Northern Wilderness chain of Heilongjiang the Great Northern Wilderness chain digital agriculture Limited by Share Ltd ("good grain agriculture") was established in 2017, is a key technology to solve the problem of Agricultural Internet plus by using block chain technology. It is committed to creating a safe agricultural proct, igniting Instrial Financial engine, and digital agriculture technology company of the food agriculture system.

3. The application of blockchain in the field of agriculture is developing day by day. Jiminsheng connects the front, back, left and right blocks of "things" into a chain with one technology, but the original data of each block can not be tampered with. It is a technology of "each mole chain" in the field of Internet of things that can be trusted by participants.

4.

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 management

2. 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

5.

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

7. The decentralization of blockchain will greatly rece the cost of Internet maintenance and enhance the intelligent and large-scale level of Agricultural Internet of things. At the same time, the agricultural procts traceability system based on blockchain technology solves the trust crisis of consumers for procts, and makes people's dining tables healthier and safer
in the field of agriculture, what are the trends of blockchain agriculture
1. Internet of things + UAV + blockchain
logistics ensures the interconnection of everything, UAV provides proction management services, and blockchain provides recording and traceability technologies. It will be concive to the development of precision agriculture, rece pesticide investment and improve the quality of agricultural procts
2. Blockchain + data + artificial intelligence
the application of blockchain in agriculture can eliminate information asymmetry to the greatest extent, improve the information transparency and timely response ability of the whole instrial chain, and realize the value-added of the whole instry
the integrated development of blockchain + data + artificial intelligence can maximize the value of agricultural big data and rece the input cost< In early February, the Chinese government issued "guidance on the revitalization of rural financial services". The new framework proposed this time is part of the financial service efficiency improvement plan in the National Rural Revitalization Plan
blockchain + agricultural finance will provide a convenient way for small farmers' loans and bring authenticity and predictability to the credit investigation of agricultural financial institutions
4. Blockchain + rural logistics
e to the small distribution of rural logistics, package loss and difficulty of agricultural procts ascending are caused. But blockchain technology can solve these problems
5. Blockchain + agricultural supply chain
this kind of application is the reason why major shopping malls graft blockchain. For example, Wal Mart, Carrefour and other large supermarkets bring the whole fresh food and food supply chain into the block chain management, so as to rece costs and improve proct safety. At present, Cargill, an American agricultural giant, is vigorously developing the application of blockchain + agricultural supply chain finance
in addition to agriculture, the application fields of blockchain include digital currency, token, finance, anti-counterfeiting traceability, privacy protection, supply chain, entertainment, etc. with the popularity of blockchain and bitcoin, many related top domain names have been registered, which has a great impact on the domain name instry.

8. The value of blockchain lies in safety, and the value of blockchain agriculture is for food safety, and these data have a very important reference role for the reproction of agricultural procts
with the development of value oriented agriculture, precision agriculture and central agricultural system, this kind of blockchain technology will promote the continuous development of the agricultural instry, and its technology can also bring more jobs
blockchain agriculture has existed for a long time, but some places are not mature enough, especially traceability. However, a dmtc agricultural traceability project was launched this year to fill the gap
in terms of data collection, through the application of artificial intelligence and Internet of things technology, it runs through the whole agricultural ecological chain. During agricultural proction, it automatically records the proction environment data and proction process data of agricultural procts, when agricultural procts are transported, it automatically records the transportation data, and when selling, dmtc terminal connects with intelligent micro supermarket to collect consumer behavior data, Through the popularization of intelligent micro supermarket, terminals are all over the living quarters, collecting rich data for instrial development, and carrying the value transmission and information transmission of agricultural ecological chain more perfectly
