Building Consumer Trust: Walmart Introducing Blockchain to Chinese Pork

What could pork chops and bitcoin, the decentralized digital currency, possibly have in common? More than you might think. The blockchain technology that powers bitcoin has the potential to reshape and transform other industries beyond finance, including food supply chains. Walmart, in partnership with IBM and Beijing’s Tshinhua University, is looking to capitalize on this digital frontier by introducing blockchain tools to the Chinese pork supply chain.[i] This technology would allow the retailer to trace the product from the farm to its Chinese storefronts to ensure quality and build consumer trust in the market.

Walmart’s Business Model in China: Struggling to Adapt to its Value Proposition to Local Tastes

Walmart entered the Chinese market early, back in 1996. Since then, its presence has expanded to roughly 400 stores (as of 2015), but the market only accounted for 2% of the Walmart’s overall revenues.[ii] Despite tailoring the stores to local tastes, the big box retailer’s customer promise of “everyday low prices” (EDLP) hasn’t fully resonated with Chinese consumers because, more than prices, Chinese customers’ top priorities are authenticity and product quality. Cheap products are often viewed with suspicion. Therefore, the success of Walmart’s EDLP model is predicated on customer trust.

Adjusting its Operating Model to Build Trust: Introducing Blockchain Technology

A blockchain in its simplest form is a distributed ledger. Imagine the ledger as a book. Everyone in the network has a copy of the same book, and every time a new transaction occurs, the same entry is entered into all of the books. If one book is destroyed, the others remain, or if a page is ripped out of one, the other books remain unaltered.[iii] The list of transactions is visible to everyone. This decentralized system contributes to the security of the system and helps to build trust across counterparties who might not trust each other because it’s very difficult to falsify or destroy the record.

The blockchain technology Walmart plans to employ is a “private database co-developed by IBM … designed to provide the retailer with a way to indelibly record a list of transactions indicating how meat has flowed through a commercial network, from producers to processors to distributors to grocers—and finally, to consumers.”[iv] Information such as farm origin, expiration dates, product temperatures, and shipping information would be stored on the blockchain. Prior efforts to secure the supply chain relied on radio ID tags and barcodes, but according to IBM global supply chain lead Paul Chang, “the missing piece was a shared forum where companies could begin to see each other’s transactions and develop trust. That missing piece is something like the blockchain.” [v]

Business Model Implications and Next Steps

If the pilot is successful in creating a supply of safe, affordable pork produced according to modern production standards, broader applications could fortify Walmart’s business model in China by convincing consumers that they can benefit from higher quality products at Walmart’s lower prices and positioning Walmart as a trusted retailer.

There are vast opportunities for expanding its approach to other food products sourced in China and other developing markets, such as produce, poultry, or seafood. A recent study by ocean conservation group Oceana revealed that one in five seafood samples tested worldwide is a completely different species that what the label claims.[vi]  Walmart stands to benefit from this approach even in developed markets, where blockchain applications could pass through more transparency to more affulent consumers concerned about sourcing and/or sustainability. Clearly, Walmart and IBM are just scratching the surface of what’s possible with blockchain. Before we know it, we might find blockchain extending from our wallets to our dinner tables.

Student comments on Building Consumer Trust: Walmart Introducing Blockchain to Chinese Pork

  1. This is very fascinating! I’ve never thought that pork and bitcoin had anything in common. The blockchain technology you described is interesting in that it shows the historical transaction of how the meat flow through the supply chain. While I understand that IBM is developing a shared forum where companies can see the information, I wonder how the information translates to the end consumer? How can you convey the quality of good pork vs. bad pork and all the information on the supply chain to the middle-aged Chinese woman, who is the typical consumer of the product? Would digitization be too sophisticated for this market?

  2. This is a very interesting article and cool overview of a unique application of blockchain! I agree that the blockchain could be used for this application and in many ways could help with the marketing efforts of Walmart in China to gain customer trust. However, I agree with Katherine that the end consumer may not be sophisticated enough to truly appreciate the nuances of a blockchain-based reporting or supply chain information management system. It may not be clear and simple enough to change brand perception of quality and freshness. Imagine having to educate the general public on what blockchain is and how it can be trusted in the pork supply chain. It’s a lot to ask.

    On a related note, I also wonder if this is an over-engineered solution. During the initial development stages of an emerging technology, it’s common to think that almost every problem can be solved by it (read: hype). In this case, I wonder if the excitement of piloting a blockchain solution has clouded IBM and Walmart’s judgement of what the optimal solution is here. Having a transparent database of information across the supply chain or certifications from supplier could perhaps be achieved by existing technology solutions. A simple database with authorizations for suppliers could be all that is needed. It seems like the blockchain would bring a level of security and immutability that isn’t needed.

    1. Andrew – I think a blockchain makes sense in this case because this is a trust issue. Every party on this pork supply chain has an incentive to tamper with data. Regulators want to have direct access to untampered data. If implemented properly, it should give regulators and Walmart a lot of transparency into a complex supply chain.

      That’s a big “if” though 🙂

  3. Great explanation of Blockchain tech!

  4. Thank you for posting an interesting article. It is indeed fascinating how many applications blockchain can have that are already being exploited by large corporates.

    I understand the skepticism stated by Katherine and Andrew. Average customer will not be able to directly translate what blockchain might offer in terms of the transparency and safety. Walmart will need to invest tons of money to educate customers how they are using blockchain to monitor the supply chain. In the short term, the resources needed to do so might not bring significantly different results if Walmart invested in educating customers how stringently they monitor supply chain without even mentioning or using blockchain technology. However, blockchain will enable Walmart to create a long term value by ensuring product quality and sustainability in the supply chain, which will provide significant competitive advantage in future.
