❶ How does blockchain protect food safety

In layman’s terms, blockchain = block + chain. Block refers to the form of data. Stored in the form of (using higher-level encryption technology, difficult to tamper with), the chain is a distributed storage technology. After the block information is stored on the chain, it will be distributed and stored in a chain-linked manner. Modifying a single node is invalid.

Using blockchain technology, food safety traceability can be carried out. This is an application scenario where blockchain technology is easier to implement and the technology is more mature. There are also many products that can be applied, including various common Commodities, high and low value-added products.
Blockchain technology can improve the situation of mutual distrust, effectively improve production relations, make it more transparent, and present traceability results digitally.
I am planning to develop a blockchain system. A friend introduced me to Guangzhou Xuanling Network Technology Co., Ltd. This is a company that specializes in 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.

❷ Food Safety and Blockchain Technology

By using blockchain, food companies can more quickly trace the source of food problems. Not only does this help reduce consumer risk and provide safety, it can also reduce financial losses through targeted recalls.

❸ Is the popularity of blockchain a hype?

Recently, virtual digital currencies have become popular, and blockchain technology has also become popular. At present, many ministries and commissions such as the Ministry of Industry and Information Technology and many industry giants at home and abroad have established specialized teams or laboratories to actively promote research on blockchain technology and its applications.

On October 13, 2017, the General Office of the State Council issued the "Guiding Opinions on Actively Promoting Supply Chain Innovation and Application" and proposed that relevant enterprises study the use of blockchain, artificial intelligence Use emerging technologies such as intelligence to establish a credit evaluation mechanism based on the supply chain. Promote the organic docking of various supply chain platforms and strengthen the disclosure and sharing of information such as credit ratings, credit records, risk warnings, illegal and untrustworthy behaviors.

At present, not only many financial institutions, related enterprises, and scientific research teams are actively investing in researching blockchain technology, but many ministries and commissions, including the Ministry of Industry and Information Technology, have also set up specialized teams or laboratories to actively promote blockchain technology and its applications. Research.

The market generally believes that blockchain technology is expected to further develop in the following aspects.

——In the financial field, it can record all transaction party information, process steps, time series and other core information in financial transactions, and ensure the authenticity and non-tamperability of the information.

——Supply chain management can record the status of goods and the flow of funds in real time to ensure the authenticity of transactions. Improve supply chain transparency while effectively preventing counterfeits from entering the market.

——Food safety management, large supermarket chains can use data blockchain technology to track foodorigin, improve food traceability, and be able to track and review the production and transportation process of food at a lower cost.

——Media and public communication, in the Internet public opinion environment, can use blockchain technology to trace the source of information, confirm the authenticity and accuracy of information, and inhibit the production and dissemination of false information.

However, Qin Yi, Deloitte Asia Pacific investment management industry leader, believes that the current large-scale application of blockchain technology is lower than expected. Further breakthroughs are needed in terms of establishing a data open alliance system, ecosystem construction, and Internet of Things application support. In particular, the strong demand for data openness caused by the "decentralization" characteristics of blockchain technology is full of resistance.

Strengthen supervision of "buying a casket for a pearl" type of speculation

Blockchain technology has attracted a wave of investment, and the virtual digital currency transactions associated with it are "hot like hell." This attracted great attention from the financial regulatory authorities, and at the beginning of the new year of 2018, they issued three articles in a row, pointing directly at virtual currencies.

As early as September 2017, seven ministries and commissions including the People's Bank of China issued an announcement clearly stating that token issuance financing is essentially an unapproved and illegal public financing act. From now on, the issued ICO (Initial Coin Offering) projects must be liquidated, and new projects are not allowed to be reissued.

Entering 2018, on January 2, the leading group for the special rectification of Internet financial risks issued a document requiring all localities to guide enterprises within their jurisdiction to withdraw from the "mining" business in an orderly manner and to report work progress regularly; On January 12, the China Internet Finance Association issued a risk warning to prevent ICO activities and named Xunlei’s “Wankebi”. On January 17, the Business Management Department of the People's Bank of China issued a notice requiring all legal person payment institutions within its jurisdiction to carry out self-examination and rectification work immediately, strictly prohibit providing services for virtual currency transactions, and take effective measures to prevent payment channels from being used for virtual currency transactions.

“There is no necessary connection between the development of blockchain technology and digital currency. Digital currency is just one of the application scenarios of blockchain technology.” Guo Feng believes that blockchain is a pearl, while digital currency is just a Box. The reason why the hype of virtual digital currency is out of control is because some people think that the "box" is exquisite, the price is opaque, and the profit can be higher than that of the "pearl". "This is a typical 'buying a casket for a pearl'."

"Monitoring and managing risks does not mean that we reject innovation." Yang Dong, director of the Financial Technology and Internet Security Research Center of Renmin University of China, believes , as a technical tool, blockchain is technology neutral and does not directly involve financial and legal risks; the current shutdown of the virtual digital currency trading platform does not conflict with the current vigorous development of blockchain.

Those who need it will pay attention, and those who don’t will not be fooled.

❹ How blockchain is applied to the food chain

Summary

Chefs can make sure their food is sustainably sourced and organic through blockchain technology. How to make sure of that? IBM thinks the solution lies in Blockchain. IBM is connecting all players in the global supply chain from farmers, procers, suppliers, manufactures in a secure shared platform---blockchain.

Blockchain is a decentralized ledger where activities throughout the whole food supply chain are recorded, verified, and become immutable at each step. This technology applies to any numbers of vegetables from fresh to packaged.

It has three advantages:

Consumers can scan the code on the package to check where the food comes from and whether it is genuinely fresh etc.

It can remove the distributor in the middle.

Traceablity (one of the functions of blockchain) can help spot the problematic food instead of decimating the whole farm in case of a food-born outbreak

Blockchain is a decentralized distributed ledger. All transaction data on the entire chain can be recorded and authenticated in the ledger and turned into tamper-proof evidence. Blockchain applications in food supplyThere are three major advantages:

1. Because every step of food from farm to table is recorded in the ledger, the information is traceable. Consumers can obtain the source information of food by scanning the code.

2. Because every step of the transaction and information is open and transparent, trust in the supply chain is increased, and the middle agent between the farmer and the purchaser can be eliminated.

3. Because the information is traceable, if a certain food causes mass poisoning/disease spread, the problem food can be accurately found and the accidental killing of other healthy foods can be reduced.

❺ What stages will blockchain go through if it wants to be popular?

I am a person related to the blockchain industry and can answer your problem. Blockchain first started in the field of encrypted digital currency and gradually expanded to other fields. For example, the financial industry is now moving towardsMature.
Other fields are also being explored, such as domestic Shanghai Wanglian Technology, which has technically applied blockchain to various industries such as agriculture, finance, and food.

❻ Blockchain can also play a role in food safety. IBM’s “Food Production and Sales History” uses blockchain technology to make Carrefour food safer

Blockchain is not only used for cryptocurrency, IBM is Cooperating with Carrefour requires "tracking" and "traceability" of the source and destination of food through blockchain.

This article comes from the cooperative media Dongzu Dongqi. INSIDE authorizes it to be reprinted by Huai Kuan. The original title is "In cooperation with the retail giant Carrefour, the blockchain "Food Production and Sales History" developed by IBM is officially launched. Enter your and my life”

According to a press release issued by the American technology giant IBM on October 8, after “18 months of testing and experimentation”, it will finally officially launch the use of blockchain technology. "Food production and sales history" based on chain technology.

This press release also revealed that the major retail company "Carrefour" will also join this blockchain ecosystem.

Emmanuel Delerm, Carrefour's blockchain director, said that the supermarket chain has been developing its own blockchain system for more than a year, with the main work being operated by its internal engineering team, and then turning to cooperation with IBM.

Carrefour from France has more than 12,000 stores in 33 countries around the world. Now Carrefour plans to use North America as a starting point to take the lead in experiencing blockchain technology for food retail stores. All kinds of benefits come.

According to information released by IBM, Carrefour is planning to roll out this technology to mass-market stores around the world by 2022.

IBM "FoodTrust" - one integration from upstream to downstream

IBM announced the launch of the "Integrity Food" project (IBMFoodTrust) in 2016, trying to use blockchain technology to connect the food industry from upstream to downstream. All businesses.

The plan has entered the trial phase since August 2017 and is being implemented jointly with a number of North American food companies. (Nestle SA, Dole Food Co., Driscoll's Inc., Gon State Foods, Kroger Co., McCormick and Co., McLane Co., Tyson Foods Inc, Unilever NV.)

Join " on Monday Also participating in the "Integrity Food" program are Topco Associates (North America's largest retail grocery purchasing organization, GPO), which represents cooperation with 15,000 stores; Wakefern, which works with retailers, representing 50 member companies and 344 stores;and suppliers including Beefchain, DennickFruitSource and Smithfield.

The "Integrity Food" program can also allow other companies to participate through a module that allows companies to upload product-related data to the system through the cloud or other applications, and is free of charge . More advanced versions include features such as certificate certification, organic certification, and fair trade credentials.

According to Coisk, Ramesh Gopinath, vice president of IBM Blockchain Solutions, explained that the main pillar of the IBM Integrity Food Program is the ability to "track" and "trace" items in the supply chain, for example, baby food brands The apples in the system can be pinpointed to specific batches and orchards; then, if contamination occurs, traces can be followed to recover all potentially affected products.

This is obviously a solution that requires food producers, suppliers and retailers to participate and send messages in a "trusted" and "permitted" way, and we connect them together. ,

Gopinath said.

According to IBM, these food companies used the food production and sales blockchain to track millions of products during the trial period of the "Integrity Food" project.

As early as 2016, another major retail company in the United States, "Walmart", had collaborated with IBM to test food production and sales record blockchain, and Walmart had successfully tracked and destroyed it several times. Problem products that have been subject to customer complaints.

In September this year, Walmart also announced that it would require suppliers selling leafy vegetables to join this food production and sales blockchain ecosystem in the future.

For IBM, the food industry is just an outpost for their use of blockchain technology. After all, IBM ranks first in the world in the number of patents it has applied for in blockchain technology, competing with Chinese e-commerce company Alibaba. Same name.

(7) Shanghai Food Blockchain Extended Reading:

Blockchain is far more than just a technology, behind it involves " The spirit of multi-party collaboration. In modern society, many things must rely on everyone's cooperation to achieve the effect of 1+1>2, but in cooperation, we need to try our best to avoid problems such as "information asymmetry."

Therefore, alliance members jointly keep accounts, share data, and make everything public to eliminate "information asymmetry" to protect everyone's interests and allow the business environment to develop healthily. If you do things honestly, you will get the benefits you deserve. If you cheat, it will be known to everyone and criticized by thousands of people. Technology is the foundation that helps realize this model. This is the more important "blockchain thinking".

❽ What exactly is blockchain and what are its uses

Recently, the word "blockchain" has appeared very frequently on the Internet. The word "blockchain" is very interesting. So what is "blockchain", how to explain "blockchain", and what kind of chain is "blockchain"?

If we want to know what “blockchain” is, we must first start with Satoshi Nakamoto.

In November 2008, Satoshi Nakamoto posted a research report on a secret cryptography review group, describing his new idea of ​​electronic currency - Satoshi Nakamoto proposed: "I believe there is a currency that doesn't rely on credit, and I can't stop myself from thinking about it." Bitcoin was born.

Although we still don’t know who Satoshi Nakamoto is, we all know the famous Bitcoin and the recently popular word “blockchain”.

In professional terms, blockchain is a new application model of computer technology such as distributed data storage, point-to-point transmission, consensus mechanism, encryption algorithm, etc.

In the original English version of the Bitcoin white paper [2], the word blockchain does not actually appear, but chain of blocks is used. In the earliest Chinese translation of the Bitcoin white paper [3], chain of blocks was translated into blockchain.

What does it mean in human terms? In layman's terms, blockchain is a decentralized distributed ledger database.

Decentralization means removing the original data center.

Here is an example of decentralization: Alibaba’s servers support Alibaba’s daily data operations, including the Double Eleven that just passed. We were able to smoothly carry out flash sales of goods at zero o’clock. Largely thanks to the support of Alibaba servers.

All data generated by Alibaba’s daily activities are recorded on the server. So what will happen if Alibaba’s server encounters an accident? (For example, Alibaba's server was hit by a meteorite, causing the server to be damaged)

After the server is paralyzed, Alibaba's data will naturally be unable to be restored in time, which will result in Alibaba being unable to maintain daily operations in the short term. operations.

However, after adopting blockchain technology, a piece of data generated by Alibaba due to daily business will not only be recorded on Alibaba’s servers, but also on various servers around the world such as the Internet and Google. In this way, even if Alibaba's servers encounter an accident, it will still not affect Alibaba's operation. The data generated by Alibaba's daily activities will still be recorded on various servers around the world. This is the advantage and benefit brought by blockchain technology.

In other words, Ali's data was only recorded in Ali's server, and Ali's server was the center. Now every server in the world is synchronously recording the business that Ali has done, and Ali's server is the center. It is no longer the only center, this step achieves decentralization. The behavior of servers around the world recording Alibaba data simultaneously is called distributed accounting.

Knowing what blockchain means, what else can blockchain bring to our lives?What kind of boundaries? What fields may blockchain be used in in the future?

1. Blockchain technology is applied in the medical and health field. For example, Xiao Zhang’s family has a history of hereditary red-green color blindness. Xiao Zhang once went to Hospital A and had his red-green color blindness checked. Now Xiao Zhang is in City B and went to Hospital B for treatment. Now Hospital B can directly treat him in his own hospital. Xiao Zhang’s previous medical treatment status was found in the database, so Hospital B no longer needs to conduct repeated examinations on Xiao Zhang. This greatly saves medical resources for the hospital and saves medical expenses for repeated examinations for Xiao Zhang.

2. Blockchain technology is applied in the field of food safety. Nowadays, everyone is paying attention to food safety, and blockchain technology is applied to the field of food safety to carry out food traceability. First, we can label each vegetable and fruit with its own label, and then record the growth, maturity, pests and diseases of the vegetables and fruits in this label. The data in this tag can be simultaneously recorded in various data centers around the world through blockchain technology.

On the one hand, when people buy vegetables, they can directly check the growth status of the vegetables. On the other hand, when our country imports and exports vegetables, we can directly check the status of the imported and exported products. No more quarantine required.
