㈠ Advantages of blockchain technology

1. Decentralization

Due to the use of distributed computing and storage, there is no centralized hardware or Management organization, the rights and obligations of any node are equal, and the data blocks in the system are jointly maintained by nodes with maintenance functions in the entire system.

2. Openness

The system is open. In addition to the private information of the transaction parties being encrypted, the blockchain data is open to everyone and anyone can The interface queries blockchain data and develops related applications, so the entire system information is highly transparent.

3. Autonomy

The blockchain adopts consensus-based specifications and protocols (such as a set of open and transparent algorithms) to enable all nodes in the entire system to trustlessly The free and safe exchange of data in the environment changes trust in "people" to trust in machines, and any human intervention has no effect.

4. Anonymity

Since the exchange between nodes follows a fixed algorithm, the data interaction does not require trust (the program rules in the blockchain will judge whether the activity is valid by itself) ), so the counterparty does not need to disclose its identity to make the other party trust itself, which is very helpful for the accumulation of credit.

Outstanding advantages:

Information cannot be tampered

Once the information is verified and added to the blockchain, it will be stored permanently unless it can be controlled at the same time More than 51% of the nodes in the system, otherwise modifications to the database on a single node will be invalid, so the data stability and reliability of the blockchain are extremely high.

(1) Extended reading on the advantages of blockchain agriculture:

Blockchain originated from Bitcoin and marked the starting point of the last financial crisis at Lehman Two weeks after the collapse of the brothers, on November 1, 2008, a person claiming to be Satoshi Nakamoto published the article "Bitcoin: A Peer-to-Peer Electronic Cash System", which elaborated on P2P network technology and encryption technology. , timestamp technology, blockchain technology and other electronic cash system architectural concepts, which marks the birth of Bitcoin.

Two months later, the theory came into practice. On January 3, 2009, the first Bitcoin genesis block with serial number 0 was born. A few days later, block number 1 appeared on January 9, 2009, and was connected to the genesis block number 0 to form a chain, marking the birth of the blockchain.

In recent years, the world's attitude towards Bitcoin has been ups and downs, but blockchain technology, one of the underlying technologies of Bitcoin, has received increasing attention. In the formation process of Bitcoin, blocks are storage units one by one, recording all communication information of each block node within a certain period of time.

The links between each block are realized through random hashing (also called hash algorithm). The latter block contains the hash value of the previous block. With the expansion of information exchange, a Blocks follow one block after another to formThe result is called blockchain[3].

㈡ Blockchain technology joins the army of promoting agriculture through science and technology. How does blockchain technology help agriculture?

Blockchain technology

< p>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 every individual economy and major companies engaged in agriculture. 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.

㈢What is the value of blockchain agriculture? What opportunities and development can blockchain bring to agriculture?

The value of blockchain lies in security. The value of blockchain agriculture It 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 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

㈣ Can blockchain agriculture really ensure food safety?

How can agricultural products be traced to their origin? Let’s take a look at the traceability of rice + blockchain
In the past, agricultural production paid special attention to "quantity security", and agricultural science and technology also focused on increasing production, resulting in the overuse and even abuse of pesticides and fertilizers, which not only caused The problem of drug residues will also bring about secondary problems such as water and soil ecological environment pollution and drug resistance.
With the changes in dietary structure and consumption patterns, the public has put forward higher requirements for the quality and safety of rice. Therefore, establishing a blockchain traceability system for rice is of great significance to both enterprises and consumers.

For consumers, they can scan the anti-counterfeiting QR code on the rice packaging at any time through their mobile phones. While checking the authenticity of the product, consumers can obtain the information from rice cultivation, processing, quality inspection, From transportation to sales and other information, you can also participate in the rewards, accumulated points, and gifts issued by the company.products and other marketing tools. Through traceability, consumers will be more assured and safer when buying rice. In order to clarify the subject of responsibility, "the source can be checked, the destination can be traced, and the responsibility can be held accountable."
For companies, rice is sown by many farmers with hard work, but due to various negative information currently on the market, rice is unsaleable. At present, many companies have begun to use advertising to promote their brands and improve consumer trust. For some small-scale enterprises that do not have enough funds to promote, blockchain traceability technology can be used to enhance consumers' trust in the brand. Not only that, companies can also set up various rewards on the traceability platform to attract more consumers.
Therefore, for rice companies and agricultural products companies, it is essential to establish a blockchain traceability system. Enterprises can use the well chain traceability platform to store multiple frames of pictures to display information on base production, processing and circulation, and pesticide residue testing of agricultural products in multiple dimensions. The entire process can be traced, creating a brand for agricultural products and achieving traceability.

㈤ What can the blockchain + agriculture model bring?

In the process of agricultural industrialization, the production and consumption places are far apart, and consumers have concerns about the pesticides and fertilizers used by producers. There is no way to understand information such as additives used in transportation and processing, and consumers’ trust in production is reduced.
Agricultural product traceability system based on blockchain technology. Once all data is recorded on the blockchain ledger, it cannot be altered. Advanced technology relying on asymmetric encryption and mathematical algorithms fundamentally eliminates human factors, making information More transparency.
I am planning to develop a blockchain game. A friend introduced me to Guangzhou Xuanling Network Technology Co., Ltd. This is a company that does software development and blockchain system development. Their development cases are pretty good and the business content involved Quite a few, the team is pretty good. I feel that the working atmosphere of this type of company is comfortable, and I hope that I can also meet a good team.

㈥ What disruptive changes will blockchain bring to traditional agriculture?

At present, there are two main directions for the combination of blockchain technology and agriculture: commercialization and agriculture. Insurance

As far as the current agricultural situation in our country is concerned, there are still many problems. For example, from the perspective of agricultural production and operation forms, the current agricultural production and operation are still It is relatively traditional and extensive. The past situation of relying on the weather has not fundamentally changed; from the perspective of sustainable development of resources, domestic agriculture produces a large amount of resources and energy consumption in the production process, which makes the ecological environment deteriorate. The damage is serious and directly affects the safety of the environment and ecology and the health of the people. From the perspective of informatization, the process of domestic agricultural informatization and modernization is still in its infancy. In the long term, more advanced technologies need to be introduced to enhance the intelligence level of the industry. Once blockchain technology matures enough, it will fundamentally change the current situation of agriculture and greatly promote the industrialization and modernization of agriculture.
