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" initiative are Topco Associates, North America's largest retail grocery purchasing organization (GPO), which works with 15,000 stores; Wakefern, which works with retailers, representing 50 member companies and 344 stores; and Beefchain , DennickFruitSource and Smithfield, among other suppliers.

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.

B. How to use blockchain in new retail

First, use blockchain technology to connect the supply chains of different commodity circulation participants with the blockchain storage system . These include origins, manufacturers, distributors, retailers, brands and consumers. Make each participant's information viewable in the blockchain system.
Secondly, the operators of the blockchain alliance chain can be roughly divided into the following categories: alliance chain, automation, visualization, data efficiency, cross-chain bridging. Each link has a complete set of operating mechanisms, and the data chain information has Comprehensiveness, automation, openness, efficiency, rationality and linkage.
This operation and management mechanism is more scientific and rational. Especially in the food industry, taking beef as an example, through the unique traceability code of the purchased beef, consumers can clearly understand the authenticity of the purchased beef and the full traceability information, which greatly enhances trust. At the same time, big data public opinion helps companies carry out smart marketing activities such as brand cultural promotion to maximize the benefits of companies and consumers.
Finally, the retail industry naturally has the obvious characteristics of fragmented transaction data, diversified transaction nodes, and complicated transaction networks.With its characteristics, the collection, storage and integration of information on commodity production, circulation and delivery are the core propositions of end-to-end retail supply chain management.
Hongqiao Technology uses blockchain to replace the paper model in the existing cross-border trade process. Through the integrity and correlation of trusted transaction data, it forms a closed-loop self-certification capability for data on the chain. Improve the document review speed and process operation efficiency in cross-border trade. Customs can directly manage the entire process of cross-border trade, review the transaction process in real time, and quickly and accurately analyze and control risks.

C. How does blockchain protect food safety?

In layman’s terms, blockchain = block + chain. Block refers to the form of data, which is based on blocks. The chain is a distributed storage technology. After the block information is stored on the chain, it is stored in a distributed manner (using higher-level encryption technology and difficult to tamper with). Modification of individual nodes 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 digitally present traceability results.
I am planning to develop a blockchain system. 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 in this type of company is comfortable, and I hope I can also meet a good team.

D. What exactly is blockchain and what are its uses

Recently, the word "blockchain" has appeared very frequently on the Internet. It can be seen that recently everyone is concerned about 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 for 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. 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.

Now that we know what blockchain means, what kind of boundaries can blockchain bring to our lives? 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. Now hospital B can directly treat his red-green color blindness in his family. 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 thenThe growth, maturity, pest and disease conditions of vegetables and fruits are recorded 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.

E. What are the survival rules at the bottom of the blockchain food chain

We know that there is such a "chain of contempt" in the financial circle: the banking industry looks down on Wall Street investors, and investors look down on stock traders. , Stock speculators look down on fund speculators, fund speculators look down on real estate speculators, and real estate speculators look down on Bitcoin traders. But you may not know that there is also such a "blockchain food chain" in the cryptocurrency industry.

This term sounds unfamiliar, but it reveals the reality of each section of the crypto mining industry chain. In this long blockchain industry

, one end is resource-heavy links such as mining machines and electricity, and the other end is heavy operation links such as mining pools and wallets. Then miners shuttle throughout this entire chain.

It is really difficult to make profits in this process. Regardless of whether it is the arrival of a calf or a big bull, miners are still surviving in the cracks

despite the favorable tide, and their profits are meager. This made the miners shout: "Miners are always at the bottom of the mining ecosystem."

As miners at the bottom of the blockchain food chain with no right to speak, how did they survive in this lengthy process? What about those who are struggling in the food chain? They

have their own "bottom survival rules".

(1) Mine:

Between the mine and the miners, the core production factor is electricity. In fact, the vast majority of miners get second-hand or even third-hand

flashlights, and they have no chance to get first-hand cheap electricity. At the same time, they often face harsh situations such as market highs, black-box operations in mining circles, and price hikes

.

So experienced miners realized the method of “pre-risking”. That is to say, priority is given to selecting high-quality mines with previous cooperation experience, and secondly, when selecting

new mines, the conditions and quality of the mines are strictly measured. When the cooperation is finally implemented into the contract, it is best to implement it in numerical values ​​rather than vague textual concepts

or textual descriptions. Through these risk-forward strategies, they can effectively avoid certain risks.

(2) Mining Pool:

Mining PoolAs a technical service provider for the crypto mining ecosystem, its uneven quality has also given miners a headache. In the process of choosing a cooperative mining pool

, it is extremely important for miners to judge the quality of the mining pool.

After paying the tuition fee of the mining pool, experienced miners have three criteria when choosing a mining pool: The first is the brand effect because of its hidden technology

The second is the scale of computing power, because it directly affects mining income; the third is human resources, because it can

effectively avoid disputes afterwards.

(3) Rights protection:

Miners are at the bottom of the blockchain food chain, which often means that their rights protection journey will be particularly difficult. After all, today's cryptocurrencies still have

regulatory gaps, and the crypto mining industry, which has not yet perfected legislation, has no way to protect the already vulnerable miners. Not only were there no standardized industry

regulations in the early days of the industry, miners often did not sign written contracts when cooperating with mining pools. When encountering unfair treatment, miners often had no choice but to "break their teeth
/>
Swallow it into your belly."

Many miners were forced to change careers. Many miners who stick to the industry place more hope in authoritative social groups or strong network resources, hoping that some prestigious authoritative institutions or community organizations can expose vicious incidents. and liars.

Just because of the "quick money", more and more people are flocking to the mining industry, but it always comes and goes in a hurry. Only a few old miners

have not forgotten their original aspirations, stick to their posts, maintain their faith in blockchain technology, and become the cornerstone of the entire encryption market. We hope that when the crypto market is booming, more people will pay attention to these miners who lack the right to speak, because they have never stopped busy,

Only then can the market development and future of the blockchain industry rise step by step today.

F. 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 connectingall 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, and all transaction data on the entire chain can It is recorded and authenticated in the ledger and becomes irreversible evidence. The application of blockchain in the field of food supply has three major advantages:

1. Because every step of food from farm to table is recorded on 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 increases.Plus, the intermediary agent between farmers and purchasers 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.
