Blockchain agricultural technology platform
of course, the most substantial progress has been made by coin Ying China, which has introced blockchain and digital currency into the crowdfunding instry. At present, a crowdfunding project has been successfully completed.
Blockchain platforms include Ethereum, Asch and other underlying application development platforms
Ethereum, an open source public blockchain platform with smart contract function, provides decentralized Ethereum virtual machine to process point-to-point contract through its special cryptocurrency ether (ETH)
arch, a decentralized application platform based on side chain technology. Asch is designed to lower the threshold of developers, such as using JavaScript as the application programming language and supporting relational database to store transaction data, which is believed to be very attractive to developers and small and medium-sized enterprises
extended data
in 2008, Nakamoto first proposed the concept of blockchain. In the following years, blockchain has become the core component of electronic currency bitcoin: public account book for all transactions
by using peer-to-peer network and distributed timestamp server, the blockchain database can be managed independently. The blockchain invented for bitcoin makes it the first digital currency to solve the problem of repeated consumption. Bitcoin's design is a source of inspiration for other applications
bitcoin is the absolute mainstream of digital currency, and digital currency is in full bloom. Bitcoin, litecoin, dogecoin, dashcoin are common. In addition to currency application, there are various derivative applications, such as Ethereum, Asch and other underlying application development platforms, as well as NXT, SIA, bitstocks, maidsafe, ripple and other instrial applications
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, etclearning 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, etclearning 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
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.
1. Traceability of agricultural procts
traceability of agricultural procts has always been a pain point in agriculture. The blockchain technology can not tamper with the records, so from the proction end to the circulation end of agricultural procts, consumers have detailed data, which can realize consumers' clear consumption and improve consumers' willingness to buy
traceability of agricultural procts can improve the safety of agricultural procts and food
2. Information transparency
in addition to traceability, the information of procers and demanders is also opaque
once blockchain technology is applied to agriculture. Through big data analysis, we can establish credit rating reference for growers and purchasers; Smart contracts are used to ensure fair trade between growers and purchasers. At the same time, blockchain technology can improve the contractual spirit of the buyers and sellers of agricultural procts
in addition, with the emergence of the block chain in the food supply chain, this can simplify the process, because the data management system, which brings a series of brokers, farmers, processors, distributors, regulators, retailers and consumers into its radar range, has become more transparent
3. Cost rection
after the application of blockchain technology, the cost of proction and circulation will be greatly reced. For example, blockchain technology solves the function of automatic information storage and database, which reces the input of labor and other facilities
in addition, the blockchain and applications realize the interconnection of everything, helping manufacturers and channel providers to rece various expenses. At the same time, the rection of proction and circulation costs will also rece the price of agricultural procts, and ultimately consumers will benefit
of course, in addition to the above three reasons, there are agricultural subsidies, land registration and other aspects. Blockchain technology can also be applied to solve the problems of corruption and rights and interests
therefore, the application of blockchain technology in the field of agriculture is recognized by people at all levels
the core advantage of blockchain technology is decentralization, which can realize point-to-point transaction, coordination and cooperation based on decentralized credit in a distributed system without mutual trust by means of data encryption, time stamp, distributed consensus and economic incentive, so as to solve the high cost and low cost of centralized institutions Low efficiency and data storage insecurity provide solutions
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.
