Fifth, each node participating in the maintenance of the equity proof blockchain can obtain a complete data record. Using the characteristics of reliable and collective maintenance of the blockchain, the rights of the owners of equity can be confirmed.
Blockchain technology is really powerful. With the advancement of the times, this technology may change the development direction and trend of the financial industry, and because the blockchain technology itself has large capacity, high-speed computing, security, and convenience And other characteristics have laid a strong foundation for the advancement and popularization of technology.

❷ 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 been recognized by people at all levels.
The core advantage of blockchain technology is decentralization, which can be implemented in a distributed system where nodes do not need to trust each other through the use of data encryption, timestamps, distributed consensus and economic incentives.Realize point-to-point transactions, coordination and collaboration based on decentralized credit, thereby 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.

❸ What is blockchain? In addition to food traceability, what other common applications does blockchain have?

Save production and distributor costs, use blockchain technology and material The Internet can realize automated data collection and storage, reducing labor investment and other equipment investment; in addition, the application of blockchain technology and the Internet of Things can help manufacturers and distributors reduce various expenditures and reduce the price of agricultural products, thereby realizing customer satisfaction. profit.

The key to blockchain technology is a distributed digital ledger that can store all types of information, including cryptocurrency transactions, NFT usage rights, and DeFi blocks chain.

Although any traditional database system can store this information, digital currency is unique in its complete blockchain technology. In contrast to systems maintained in core organizations by central administrators (such as Excel spreadsheets or bank database systems), blockchain databases have many identical copies stored on multiple computers that exist on the network, but these independent electronic Computers are called connection points.

The name "blockchain technology" is not a whim. Data ledgers are generally described as "chains" composed of separate "data blocks". When new data is imported into the network, a new "block" is created and added to the "chain," which involves all nodes updating their versions of the blockchain ledger so that they are the same.

❹ Blockchain is applied to the chicken industry. Each chicken is equipped with a smart anklet. Do you dare to eat it with confidence?

Blockchain is applied to the chicken industry. Do you dare? Feel free to eat?

I recently read a piece of news that ZhongAn Technology, a subsidiary of ZhongAn Insurance, the first Internet insurance company, announced that it would apply blockchain to the chicken industry for the first time in China and support domestic blockchain startups. Mo Technology launches the "BuBu Chicken" project to provide consumers with more trustworthy food.

To be honest, food safety in China has always been questioned by many people, especially the previous incidents of "poisonous milk powder", "poisonous rice", and the recent fake vaccine incident, which have made everyone panic. , there is even news about making fake eggs on the Internet. To be honest, we don’t dare to eat even a small egg or chicken now, because we are either afraid that the egg is fake or that there is something wrong with the chicken feed.

But eggs andChicken is an essential food with four major nutrients. Can people not eat it? This is impossible. You can only try to buy some chickens that are said to be fed with high-quality feed or from some sellers who claim to be pheasants or native chickens. I see that the aunties around me buy chickens or eggs from Dongshi’s, which I believe is more expensive in terms of price, thinking that more expensive ones are always better.

Although the cost of free-range chickens is higher, now that living standards have improved, most consumers still like to pay for green and healthy food.

If we could fundamentally know the food that chickens eat and the vaccines that chickens use during their growth, wouldn’t everyone feel more at ease! As far as we know, the biggest features of blockchain are its non-tamperability and consensus mechanism. If blockchain is applied to the breeding industry, will it increase food safety? Can it increase consumers’ trust in food?

There is no doubt that using blockchain technology to track the growth data of chickens, with corresponding records in every link, will greatly increase consumer trust and satisfaction. Let’s take a look, can we apply blockchain technology to practice?

In Cha'an Town, Shou County, Anhui Province, there is a kind of chicken called "Bu Bu Chicken". Bubu Chicken Breeding integrates the Internet of Things, blockchain, artificial intelligence, and internationally patented anti-counterfeiting technology, and each chicken wears an Internet of Things identity card—a chicken tag. Chicken Tag can automatically collect chicken location and movement data and upload it to the blockchain in real time. In order to ensure that the chicken brand cannot be copied, the equipment adopts the internationally patented anti-counterfeiting technology provided by Wopu IoT, combined with chaos anti-counterfeiting, optical anti-counterfeiting and other technologies. One chicken, one brand, will be destroyed after disassembly. It is reported that the blockchain anti-counterfeiting label incorporates national secret-level algorithms, chaos principles, laser optics, mobile APP intelligent dynamic image scanning, cloud data comparison and other technologies, making it difficult to imitate, copy and recycle, ensuring the authenticity of goods from source to terminal. Uniqueness.

In addition, the blockchain chicken breeding experimental base of Team 6, Xinsheng Village, Shengci Town, Jingjiang City, Jiangsu Province is being put into practice. Hundreds of ecological free-range chickens forage freely, which is very different from the daily life of caged chickens. This is exactly the scene at the Zhongan Technology blockchain project farm. Here, every chicken wears an IoT ID card—— Chicken brand. It is reported that based on the full-ecological blockchain technology output by Zhongan Technology’s Anlian Cloud, the entire process of Bubu Chicken is recorded from chicks into the pen, to adult chickens, slaughtering and transportation, and to the user’s dining table.

Relevant personnel said: “The non-tampering characteristics of blockchain will help improve consumers’ trust in rural products, thereby realizing the high-end development of rural brands and changing the market position of farmers and rural brands. At the same time, it also expands the boundaries of rural finance.”

Many people worry about whether someone will tamper with information. This bigDon't worry, family. Because tampering with one piece of information requires all the information on a blockchain to be changed, which costs too much material and financial resources and is very uneconomical. Currently, Zhongan Technology has signed contracts with more than 400 ecological chicken breeding bases across the country. It is understood that Zhongan Technology has reached cooperation intentions with breeding farms in Anhui, Henan, Guizhou and other provinces and cities. It is expected that 2,500 breeding farms will be established across the country in the next three years, directly benefiting 15,000 farmers and indirectly helping 150,000 poor people. population. Based on an average of 30 acres of land for a farm to raise 1,000 ecological free-range chickens, it is estimated that by 2020, the annual sales volume of "BuBu Chicken" will reach 20 million.

Seeing this, do you think it would be very good to apply blockchain to the breeding industry? Not only can you see the growth process of chickens from small to large, but it also allows everyone to buy chickens and eggs with confidence. , no longer worry about buying sick chickens or fake eggs.

It is hoped that the non-tampering and consensus features of the blockchain can be applied to the breeding and animal husbandry industries in the future, which can help improve consumers’ trust in rural products, thereby achieving high-end rural brands and changing The market position of farmers and rural brands will also expand the development of rural finance and increase people's income. I hope that day will come sooner.

❽ Can blockchain agriculture really ensure food safety?

What about agricultural products? How to trace the origin? Let’s take a look at the road to traceability of rice + blockchain
In the past, agricultural production paid special attention to “quantity security”."Complete", the focus of agricultural science and technology is also on increasing production, resulting in the overuse and even abuse of pesticides and fertilizers, which will not only cause drug residue problems, but also bring about secondary problems such as water and soil ecological environment pollution and drug resistance.
With changes in dietary structure and consumption patterns, the public has put forward higher requirements for the quality and safety of rice, so 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 with their mobile phones. While checking the authenticity of the product, consumers can obtain rice from planting, processing, quality inspection, transportation to sales. and other information, you can also participate in marketing methods such as rewards, accumulated points, gifts issued by the company. Through traceability, consumers will be more assured and safer when buying rice. In order to clarify the responsible party, we can realize that "the source can be checked and the whereabouts can be traced. Responsibility can be held accountable.
For companies, rice is sown with hard work by many farmers, but due to various negative information currently on the market, rice is unsaleable. Currently, many companies have begun to use advertising to promote own brand to improve consumers’ 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. Companies can use wells to The chain traceability platform stores 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.
