How Walmart Uses Blockchain in Supply Chain Management

9 min read

Supply chains are important for any service that offers any sort of item. Even if you are merely offering soap produced by your next-door neighbor, you will still have to take part in some standard supply chain management. The larger your business and the longer the distances products need to travel, the more complicated the supply chain.

Although it has actually been understood for ages that supply chain management has a ton of concerns it has been struggling to fix, they have actually not been that apparent– and pushing– prior to the pandemic hit.

In the past two years, it has become more important than ever to be able to tell where the food on your plate has come from, along with what journey it had to go through to make it to your cooking area. Furthermore, shipping congestion has ended up being a concern: as shipment times had to be extended, disposable items like food have suffered one of the most.

Walmart, an international retail corporation that offers whatever from patio area furnishings to the most recent iPhones but is particularly famous for being a grocery hypermarket, has actually decided to resolve those pressing issues in the supply chain and food industry using blockchain technology.

What Is Blockchain?

Blockchain is a type of digital dispersed database that is shared across multiple individuals of a computer network. It groups information into blocks that have a particular established storage capacity. Once a block is filled, it gets added to the blockchain– and from that point on, the information taped because block can never ever be altered again. Blockchain is used in several methods but is most well-known for being the backbone of cryptocurrencies like Bitcoin or Ethereum, NFTs, DeFi, and dApps.

Blockchains are mainly identified by seven primary homes:

🦾 Programmable Blockchains are completely programmable and can be used to create decentralized applications, smart contracts, tokens, and so on.

Furthermore, they make all details widely accessible and easily retrievable. Unlike standard journals, blockchains can offer all the required information within minutes, if not seconds.

Blockchain and the Food Supply Chain

Blockchains have lots of use cases in the contemporary world and are a best suitable for the supply chain sector. The transparency and immutability of data they can supply are of particular value to the food industry.

Let’s have a look at a few of the common issues present in the supply chain market and how blockchain can be used if not to remove, then at least to minimize the negative results these problems have on the entire food supply ecosystem.

Food Safety

Foodborne diseases and disease control are gradually ending up being a significantly larger concern as lots of companies and stores move their production and packaging centers to countries with loose food security guidelines.

Whenever there are outbreaks of foodborne illness, it can in some cases take weeks to discover their source. As soon as the source is found, it can take even longer to track all the places where the ingredients might have ended up– and when it comes to perishable items, that means contaminated items may wind up on consumers’ racks long before the disease is determined. In such situations, all that can be done is to inform clients to prevent specific groups of items, and it’s hardly an effective or effective option.

Blockchains can assist to track infected food in a much clearer, transparent, and effective method. They will make recognizing the specific warehouse where each food product has gone through a quick and easy affair. Right now, it can take weeks to trace some products, which is incredibly time-consuming and can be harmful to public health. Blockchain reduces the time it requires to find the data on particular food products from 7 days to 2.2 seconds.

Food System Efficiency

The improved traceability offered by blockchain can protect not just the customers but likewise the farmers and other food producers. It will minimize the possibility of clients deserting one group of items entirely on the off chance that it can be contaminated and permit providers to easily identify where the break out has actually begun in order to look after it and resume normal operations as rapidly as possible. This can greatly benefit all of the individuals of food supply chains, from farmers to trucking companies to supermarket.

Waste is among the most significant difficulties that the food industry deals with. Every day, countless products get thrown away or rot away on the racks. Additionally, overproduction is one of the reasons why this sector has such a high carbon footprint and wastes thousands of tons of water every year.

While some of the concerns in the food system can be credited to the greed and bad practices of individual organizations, there’s no denying that the whole food supply chain is extremely inefficient.

A food traceability system based upon blockchain innovation can help substantially lower waste and increase the performance of supply chains. All the information, including the production date, how long it considered the item to reach the shelves, when (and if) it was lastly sold, how it was stored– all of it will be tape-recorded on a blockchain.

Blockchains can make recording, recovering, and evaluating information a much quicker and simpler process, hence increasing the performance of all parts of the food supply chain.

Food Fraud

Blockchains can not just make it much easier to investigate disease break outs and find and identify all infected goods however also expose supply chain participants who manipulate information and objective to increase their earnings at the cost of customers’ health. For instance, blockchains can make it much harder to create expiration dates, control the freshness of an item, and even lie about the origins of various foods.

A few years earlier, there was a big food sector-related scandal that exposed some glaring issues in the supply chain market. It ended up that the Australian meat that was sold in China was really horse meat, not beef. Such falsification would have been difficult if blockchain technology had actually been included– both customers and Chinese grocery stores would have been able to quickly examine where any particular piece of meat originated from immediately.

Market Transparency

This point is somewhat associated to the previous one– blockchain will easily have the ability to expose any fraudulent activities along the supply chain. Customers will have the ability to know what exactly they are spending for, while suppliers will get a fuller photo of how their cash gets designated and invested.

The increased openness that blockchain technology can offer has the potential to make durable goods pricing much fairer. Furthermore, blockchain technology can make it easier to gain access to and process all the data that worries food supply chains, therefore increasing the efficiency of different demand forecasts and analyses.

Walmart and Blockchain Technology

Walmart has actually efficiently used blockchain not just to increase the efficiency of its food supply chain but also to improve the customer experience all around the globe. Let’s take a more detailed look at the history of their blockchain-based supply chain effort.

When Did Walmart Start Using Blockchain?

There have actually been many cases when inadequacies in standard supply chain solutions have triggered Walmart and other grocery supermarkets a great deal of issues. Perhaps the most infamous foodborne disease break out happened in early 2018: five people died, and over 200 were hospitalized after consuming romaine lettuce.

Due to how hard it is to track goods using the traditional paper-based technique of information keeping, the examination of where the disease came from and what was triggering it took almost a year. This greatly disrupted the farming industry and triggered a lot of harm to both customers and providers.

Walmart introduced two proof-of-concept jobs for its blockchain food traceability system back in 2016. Among them was concentrated on tracing mangoes in US stores, and the other was set on monitoring pork across Walmart stores in China. After both tests turned out to be a success, Walmart formally partnered with IBM in 2017.

The next year, Walmart started tracing over 25 various types of products using the technology supplied by the IBM Food Trust. In September 2018, Walmart officially revealed that all their providers of leafy green veggies should upload their data to the blockchain within a year.

Walmart & & Blockchain Use Cases

In 2019, Walmart went one step even more by releasing a traceability platform in their Chinese stores. While food safety concerns are a concern all across the world, they are (or, at least, used to be) an especially big concern in China. After the Australian beef incident, numerous customers lost their rely on grocery stores and the food they offer.

As part of this program, numerous food products, consisting of but not limited to pork, chicken, packaged salads, and more, were each designated their own QR codes. Consumers might scan those codes to see where each item came from and how it got to the Walmart store they were shopping in. Additionally, this innovation makes it possible to trace all of the ingredients of each item.

Something like this would not have actually been possible without utilizing a blockchain-based tracking system. No other innovation can ensuring the full immutability of all information while still maintaining full openness and ease of traceability.

The business’s goals for blockchain execution consist of not only the increase in total effectiveness and ease of performing food safety protocols however also an improvement in consumer experience.

Among the greatest obstacles related to blockchain-based options is how new and novel the technology is. Many business still lack the technical know-how and understanding needed to embrace and utilize blockchain. Walmart knew this and collaborated with IBM to ensure that all companies, regardless of their know-how level, would be able to use the new innovation. They have actually created a special onboarding program that reduces new users into the system.

One of the obstacles that blockchain innovation can’t conquer yet is the process of making sure the information that gets taped on the blockchain is authentic. Because it is almost difficult to verify data that can just be accessed by one celebration– be it a trucking company, a farmer, or a particular Walmart store– there is a possibility that the information that gets tape-recorded on the blockchain will be incorrect. While automatization can resolve the issue of human mistake, it is tough to say how huge business like Walmart can identify and prevent any destructive actions from happening.

What Blockchain Does Walmart Use?

Walmart uses the IBM Food Trust platform, which was developed using Hyperledger Fabric and operates on the IBM cloud.

The Walmart China food traceability system was powered by VeChain’s Thor blockchain technology in cooperation with PwC.

IBM Food Trust

IBM Food Trust is a significant worldwide effort that aims to improve the efficiency, safety, transparency, and sustainability of the whole food supply chain using blockchain technology. While Walmart is seen by numerous as a pioneer when it comes to collaborating with this platform, there are other food business that have also dealt with IBM in the past: Carrefour, Unilever, Nestlé, and many others.

IBM’s blockchain options log deals at every step of the supply chain process, utilizing the transparency and security supplied by the innovation to take care of food security dangers, reduce waste, and increase performance in all operational processes in the food industry.

This program allows both providers and clients to track such things as where food comes from, what components were utilized to make it, how it was stored and produced, and more. In addition to decreasing food safety-associated threats, this system helps to resolve labeling errors, avoid food scams, and evaluate life span even more accurately.

The more business join the program, the more accurate its data and predictions will be. Blockchain is an ideal fit for the supply chain industry, so it’s likely that this specific initiative and other comparable ones might become mainstream in the future.
