A. How does the application of blockchain technology in the agricultural field help?
What problems does blockchain solve in agriculture?
1. Traceability of agricultural products
The traceability of agricultural products has always been a pain point in agriculture. Blockchain technology can make records non-tamperable, so there is detailed data from the production end of agricultural products to the circulation end and consumers, which can realize consumers' clear consumption and increase consumers' willingness to buy.
The traceability of agricultural products can improve the safety of agricultural products and food.
2. Information transparency
In addition to traceability in the agricultural field, there is also the problem of opacity in the information between producers and demanders.
Once blockchain technology is applied to agriculture. We can use big data analysis to establish credit rating references for growers and purchasers; use smart contracts to ensure fair transactions between growers and purchasers. At the same time, blockchain technology can improve the contractual spirit between buyers and sellers of agricultural products.
Also, with the advent of blockchain in the food supply chain, this could streamline the process as the data management system integrates a range of brokers, farmers, processors, distributors, regulators, retailers and Data management systems are becoming more transparent for consumers to put on their radar.
3. Reduce costs
After the application of blockchain technology, the costs of production and circulation will be greatly reduced. For example, blockchain technology solves the functions of automatic information storage and database, thus reducing manual investment and investment in other facilities.
In addition, blockchain and applications realize the interconnection of everything, helping manufacturers and distributors reduce various expenses. At the same time, reductions in production and distribution costs will also reduce the prices of agricultural products, ultimately benefiting consumers.
Of course, in addition to the above three reasons, blockchain technology can also be applied in agricultural subsidies, land registration, etc. to solve problems such as corruption and rights and interests.
Therefore, the application of blockchain technology in the agricultural field has to be recognized by people at all levels.
The core advantage of blockchain technology is decentralization. It can achieve decentralized credit in a distributed system where nodes do not need to trust each other by using data encryption, timestamps, distributed consensus and economic incentives. Point-to-point transactions, coordination and collaboration, thus providing solutions to the problems of high cost, low efficiency and insecure data storage common in centralized institutions.
The application fields of blockchain include digital currency, certificates, finance, anti-counterfeiting and traceability, privacy protection, supply chain, entertainment, etc. With the popularity of blockchain and Bitcoin, many related top domain names have been registered. , which has had a relatively large impact on the domain name industry.
B. What are the blockchain applications in the agricultural field?
Blockchain decentralization and other characteristics will significantly reduce Internet maintenance costs and enhance the intelligence and scale of the agricultural Internet of Things. level. At the same time, the agricultural product traceability system based on blockchain technology solves the problem of consumers’ trust in products.Let’s overcome the crisis and make people’s dining tables healthier and safer.
In the agricultural field, what trends and directions will blockchain agriculture present?
1. Internet of Things + Drones + Blockchain
Logistics ensures the interconnection of all things, drones provide production management services, and blockchain provides recording and traceability technologies. It will be conducive to the development of precision agriculture, reduce pesticide input, and improve the quality of agricultural products.
2. Blockchain + Data + Artificial Intelligence
Blockchain applied to agriculture can eliminate information asymmetry to the greatest extent, improve information transparency and timely response capabilities of the entire industry chain, thereby realizing the realization of the entire industry value added.
The integrated development of blockchain + data + artificial intelligence can maximize the value of agricultural big data and reduce input costs.
3. Blockchain + Agricultural Finance
In early February, the Chinese government issued the “Guiding Opinions on the Revitalization of Rural Financial Services.” The new framework proposed this time is part of the plan to improve the efficiency of financial services in the national rural revitalization plan.
Blockchain + agricultural finance will provide convenient access to loans to small farmers and bring authenticity and predictability to the credit reporting of agricultural financial institutions.
4. Blockchain + Rural Logistics
Due to the fragmentation of rural logistics, parcels are lost and agricultural products are difficult to transport. But blockchain technology can solve these problems.
5. Blockchain + Agricultural Supply Chain
This type of application is the reason why major shopping malls are grafting blockchain. For example, large supermarkets such as Walmart and Carrefour have incorporated the entire fresh food and food supply chain into blockchain management, thereby reducing costs and improving product safety. At present, American agricultural giants such as Cargill are vigorously developing the application of blockchain + agricultural supply chain finance.
In addition to agriculture, the application fields of blockchain include digital currency, certificates, finance, anti-counterfeiting and traceability, privacy protection, supply chain, entertainment, etc. The popularity of blockchain and Bitcoin has led to many related top All domain names have been registered, which has had a relatively large impact on the domain name industry.
C. What is the core technology of DMTC agricultural traceability blockchain?
The core technologies of agricultural traceability blockchain are: one is the decentralization of the blockchain (distributed on the network ) and cannot be tampered with to ensure data security and reliability. The second is to communicate directly with the nodes through intelligent monitoring equipment in real time, store relevant data in the nodes, and broadcast it to the entire chain. The third is to use radio frequency identification (RFID, something like a QR code) and chips to use The traceability of blockchain establishes a traceability mechanism for agricultural products
D. What is the value of blockchain agriculture and what opportunities and development can blockchain bring to agriculture?
District The value of blockchain lies in security, and the value of blockchain agriculture is for food safety, and these data play a very important reference role in the reproduction of agricultural products.
With the development of value-oriented agriculture, precision agriculture and centralized agricultural systems, this kind of blockChain technology will promote the continuous development of the agricultural industry, and its technology can also bring more jobs.
Blockchain agriculture has already existed, but some areas are not mature enough, especially the traceability aspect. However, the launch of a Dmtc agricultural traceability project this year has filled this gap.
In terms of data collection, through the use of artificial intelligence and Internet of Things technology, it runs through the entire agricultural ecological chain. During agricultural production, the production environment data and production process data of agricultural products are fully automatically recorded. When agricultural products are transported, they are fully automatically recorded. For transportation data, DMTC terminals are connected to smart micromarkets during sales to collect consumption behavior data of product consumers. Through the popularization of smart micromarkets, terminals are spread throughout living quarters, collecting rich data for industrial development and progress, and more fully carrying the value of the agricultural ecological chain. Transmission and information transmission

1. Make agricultural products traceable: The most common use of blockchain in food and agricultural supply chains is to improve traceability. It enables companies to quickly trace unsafe produce to its source and where it was distributed. This prevents disease, saves lives and reduces the cost of product recalls.
F. What is blockchain technology? What are the core components of blockchain technology?
What is blockchain technology? What are the core components of blockchain technology? What is blockchain technology:
Blockchain is a new application model of computer technology such as distributed data storage, point-to-point transmission, consensus mechanism, encryption algorithm, etc. The so-called consensus mechanism is a mathematical algorithm that establishes trust and obtains rights and interests between different nodes in the blockchain system.
Blockchain is an important concept of Bitcoin. It is essentially a decentralized database and serves as the underlying technology of Bitcoin. The blockchain is a series of data blocks generated using cryptographic methods. Each data block contains information about a Bitcoin network transaction and is used to verify the validity of its information (anti-counterfeiting) and generate the next block.
The core components of blockchain technology:
Blockchain mainly solves the trust and security issues of transactions, so it proposes four technological innovations to address this issue:
The first one is called distribution A type of ledger means that transaction accounting is completed by multiple nodes distributed in different places, and each node records a complete account, so they can all participate in supervising the legality of the transaction and can also jointly testify for it.
Different from traditional distributed storage, the uniqueness of blockchain distributed storage is mainly reflected in two aspects: First, each node of the blockchain stores complete data according to the block chain structure.Traditional distributed storage generally divides data into multiple parts for storage according to certain rules. Second, the storage of each node in the blockchain is independent and of equal status, relying on the consensus mechanism to ensure storage consistency, while traditional distributed storage generally synchronizes data to other backup nodes through the central node. [8]
No node can record ledger data independently, thus avoiding the possibility of a single bookkeeper being controlled or bribed to record false accounts. Also because there are enough accounting nodes, theoretically speaking, the accounts will not be lost unless all nodes are destroyed, thereby ensuring the security of the accounting data.
The second one is called asymmetric encryption and authorization technology. The transaction information stored on the blockchain is public, but the account identity information is highly encrypted and can only be accessed with the authorization of the data owner. This ensures data security and personal privacy.
The third one is called the consensus mechanism, which is how all accounting nodes reach a consensus to determine the validity of a record. This is both a means of identification and a means of preventing tampering. Blockchain proposes four different consensus mechanisms, which are suitable for different application scenarios and strike a balance between efficiency and security.
The consensus mechanism of the blockchain has the characteristics of "the minority obeys the majority" and "everyone is equal". "The minority obeys the majority" does not entirely refer to the number of nodes, but can also be computing power, the number of shares, or other factors. A characteristic quantity that a computer can compare. "Everyone is equal" means that when a node meets the conditions, all nodes have the right to give priority to the consensus result, which will be directly recognized by other nodes and may eventually become the final consensus result. [8]
Taking Bitcoin as an example, it uses proof of work. Only when more than 51% of the accounting nodes in the entire network are controlled, it is possible to forge a non-existent record. When there are enough nodes joining the blockchain, this is basically impossible, thus eliminating the possibility of fraud.
The last technical feature is called smart contracts. Smart contracts are based on these trustworthy and non-tamperable data and can automatically execute some predefined rules and terms. Take insurance as an example. If everyone's information (including medical information and risk occurrence information) is true and trustworthy, it will be easy to automate claims settlement in some standardized insurance products.
In the daily business of insurance companies, although transactions are not as frequent as those in the banking and securities industries, the reliance on trusted data continues unabated. Therefore, the author believes that using blockchain technology from the perspective of data management can effectively help insurance companies improve their risk management capabilities. Specifically speaking, it is mainly divided into risk management of policyholders and risk supervision of insurance companies.
Chongqing Jinwowo Analysis: The consensus mechanism is the core of blockchain technology. The consensus mechanism largely determines the degree of mutual trust between nodes in the entire blockchain system, and also determines other users’ views on the blockchain. superiorLevel of trust in data
What is the core component of blockchain technology? Analysis by Chongqing Jinwowo: Blockchain technology consists of three core technologies: consensus mechanism, common defense mechanism, and distributed storage.
The three core technologies are supported by machine trust, that is, through the support of network technology, breakthroughs in difficult problems such as point-to-point transaction, decentralization, non-tampering of recorded information, irreversible transactions, and information encryption are achieved through network technology support.
The development of blockchain technology is becoming more and more prosperous with the continuous expansion of applications. This powerful development force coming from the needs of various industries has caused rapid changes in blockchain technology, allowing various industries to achieve great results. The results are attracting more and more attention, and professional technologies and resources are constantly concentrated in this industry, thus bringing the development of blockchain technology to a new stage, and the impact of this development of blockchain technology has also much attention.
When talking about blockchain technology, Bitcoin has to be mentioned. Many people know that the electronic currency Bitcoin does not rely on the issuance of a specific monetary institution, but is generated through a large number of calculations by a specific algorithm. In fact, the core that truly supports Bitcoin is blockchain technology.
How does the invisible and intangible Bitcoin operate through blockchain technology? The interpretation circulated in the industry is that blockchain can be regarded as a technical solution for collectively maintaining reliable databases through "decentralization" and "trustlessness". In layman’s terms, this technology can be understood as a technology in which everyone participates in accounting. In the past, people used centralized servers to keep accounts, but in the blockchain technology system, everyone can participate in accounting and jointly identify Authenticity of records.
"Through this technology, even if there is no neutral third-party organization, two parties that do not trust each other can achieve cooperation. In short, the blockchain is like a 'machine that creates trust.'" Bubi Company It is a leading blockchain service provider in China and has made many breakthroughs in the blockchain technology platform. It can meet scenarios with tens of millions of users and has the ability to quickly build upper-layer application businesses.
The blockchain technology used by all parties involved in recording and storing information adopts a decentralized distributed structure, which saves a lot of intermediary costs and can better ensure data security; at the same time, it has a time stamp that cannot be tampered with. It can effectively solve problems such as data tracking and information anti-counterfeiting.
Will it become the next trend of Internet finance?
Although blockchain emerged with Bitcoin, the derived value of this technology has transcended digital currency. Bubi Blockchain focuses on the innovation of blockchain technology and products. It already possesses a number of core technologies and has developed its own blockchain service platform. With decentralized trust as the core, we are committed to building an open value circulation network to allow digital assets to flow freely. What Bubi wants to do is to create a new technology and product - to realize real value circulation and bring the Internet to a new level. With the application of this technology, there will be no need to transfer assets when transferring assets.There is a central institution that can realize the direct transfer of assets between us.
In the current international financial market, the U.S. Central Bank, Swiss Bank, and some insurance and futures companies are all competing to develop blockchain technology. Fang Liang introduced that in the Internet financial industry, blockchain technology will first affect financial infrastructure such as payment systems, securities settlement systems, and transaction databases; later, the technology will also expand to general financial services, such as credit systems and "anti-money laundering" "wait.
"The payment and clearing system in the financial field will evolve towards decentralization. The electronic ledger supported by blockchain technology is a reliable system that is error-free and cannot be tampered with. It has various functions for payment, clearing, transaction, confirmation of rights, etc. A profound impact," Li Yan said.
Therefore, industry insiders believe that blockchain technology may be the next trend in the Internet financial industry. As the interconnection of all things deepens, Yang Tao, assistant director of the Institute of Finance, Chinese Academy of Social Sciences, also said that blockchain will make it possible for all individuals to become important nodes in the allocation of financial resources, and will also promote the improvement of existing financial system rules. Build a shared and win-win financial development ecosystem.
Blockchain technology will affect many industries
"Blockchain technology has been widely used in the era of big data." Li Yan said frankly that in addition to the Internet financial field, blockchain technology has been used in many industries. It has been applied in many fields and has shown great prospects.
For example, the healthcare industry has benefited greatly from blockchain technology. In reality, patient private information leaks often occur, and centralized database or file cabinet management in medical departments is no longer the optimal choice. Medical institutions are using blockchain technology to keep patients' private information confidential.
In addition, blockchain technology also has important legal implications. In some civil fields, it is often necessary to provide evidence to determine blame, and blockchain technology can record every step and help judicial authorities identify the specific responsible person.
"Especially in the field of assets, whether it is physical assets such as real estate and cars, or intangible assets such as health and reputation, this technology can be used to complete registration, transactions, and tracking. It can be said that any production and life that lacks trust In all fields, blockchain technology will have its place."
The development of blockchain technology has also brought about changes in the operational concepts of various industries. New technologies and new concepts have promoted new developments in various industries. This The impact of this driving force on society and the promotion of economic activities are also huge. Many new industry phenomena will occur one after another, and the public is also waiting and watching, expecting this brand-new technology to be used by various industries and better benefit all industries.
The so-called blockchain technology, also known as distributed ledger technology, is an Internet database technology that is characterized by decentralization. , open and transparent, allowing everyone to participate in database records.
Explained in layman’s terms: If the database is assumed to be a ledger, reading and writingThe database can be regarded as a kind of bookkeeping behavior. The principle of blockchain technology is to find the person with the fastest and best bookkeeping within a period of time. This person will keep the bookkeeping and then send the information on this page of the ledger. To everyone else in the system. This is equivalent to changing all the records in the database and sending them to every other node in the entire network, so blockchain technology is also called a distributed ledger.
What is the core technology of Jinwowo blockchain technology?
Chongqing Jinwowo analyzes the core technologies of blockchain technology as follows:
Distributed ledger technology, asymmetric encryption technology and smart contracts.
The core of the blockchain is that it stores all information in an independent personal computer network, making it a decentralized and distributed structure.
This means that the system is not owned by a controlling company or person, but that everyone can use and run the system.

What is blockchain technology?Blockchain has been hyped up like crazy, but you know nothing about it!
Blockchain is a distributed database system participated by different nodes and an open ledger system.
It consists of a series of data blocks or data packets generated according to cryptographic methods, that is, blocks. Each block of data information is automatically timestamped, thus Calculate a data encryption value, that is, a hash value (hash).
Blockchain technology is essentially a distributed accounting technology. It allows everyone to have an instantly synchronized ledger in their hands. Every transaction that occurs in the entire network will have thousands of backups and synchronous records. When perpetrators attempt to tamper with ledger data, they must change the ledger in the hands of the majority of people to achieve their goal.
G. Blockchain technology joins the army of promoting agriculture through science and technology. How does blockchain technology help agriculture?
Blockchain technology
Blockchain application scenarios cover agricultural product logistics, traceability, supply chain management and other fields. Moreover, the original market size of these traditional agricultural products is large enough.
Blockchain technology selects the best one from all agricultural developments, and at the same time expands the best development methods and farming methods to everyone engaged in agriculture.individual economies and major economic groups. And by imitating the rapid development of agriculture, we can promote the purpose of promoting agriculture, achieve scientific and technological development of agriculture, and achieve rapid economic growth.
This is how blockchain technology helps farmers.
