Walmart thought that blockchain technology might be a good fit for the decentralized food supply ecosystem. To test this hypothesis, the company created a food traceability system based on Hyperledger Fabric. Walmart, together with its technology partner IBM, ran two proof of concept projects to test the system. One project was about tracing mangos sold in Walmart's US stores and the other aimed to trace pork sold in its China stores. The Hyperledger Fabric blockchain-based food traceability system built for the two products worked. For pork in China, it allowed uploading certificates of authenticity to the blockchain, bringing more trust to a system where that used to be a serious issue. And for mangoes in the US, the time needed to trace their provenance went from 7 days to... 2.2 seconds! Results Walmart can now trace the origin of over 25 products from 5 different suppliers using a system powered by Hyperledger Fabric. The company plans to roll out the system to more products and categories in the near future. In fact, it has recently announced that it will start requiring all of its suppliers of fresh leafy greens (like salad and spinach) to trace their products using the system.

To get started, go to the Home tab and apply Heading styles to the headings in your document. "People talk about the food supply chain," says Frank Yiannas, former Vice President of Food Safety at Walmart. "But it is not actually a chain, it's a complex network." When an outbreak of a food-borne disease does happen, it can take days, if not weeks, to find its source. If investigators cannot point to a specific farm or farms, the government usually advises consumers to avoid products grown in a certain area (as happened with romaine lettuce from Yuma, Arizona), or even to avoid the type of product altogether. According to Walmart, millions of bags or heads of lettuce had to be removed, and consumers lost confidence in romaine lettuce altogether. Better traceability could help save lives by allowing companies to act faster and protect the livelihoods of farmers by only discarding produce from the affected farms. For this reason, Walmart has always been interested in enhancing transparency and traceability in the food system.

When Yiannas Search document first heard about blockchain and the idea of using it to trace food in the supply chain, he was skeptical. Headings Pages Results Choosing the blockchain Create an interactive outline of your document. Walmart Technology considered several blockchain technologies but ultimately decided to go for Hyperledger Fabric. It's a great way to keep track of where you are or quickly move your content around. "IBM brought Hyperledger Fabric to us. We looked into Ethereum, Burrow project and others. To get started, go to the Home tab and apply Heading styles to the headings in your document. Ultimately, we decided to go with Hyperledger Fabric because it met most of our needs for a blockchain technology," Bedwell said. "We felt that it best met our needs. It is an enterprise-grade blockchain technology, and it is permissioned." The team also found it important to work with an open-source, vendor-neutral blockchain. Since the food traceability system was meant to be used by many parties, including Walmart's suppliers and even direct competitors, the technology ecosystem underlying it needed to be open. Hyperledger Fabric is a blockchain framework implementation and one of the Hyperledger projects hosted by The Linux Foundation. Intended as a foundation for developing applications or solutions with a modular architecture, Hyperledger Fabric allows components, such as consensus and membership services, to be plug-and-play. Hyperledger Fabric leverages container technology to host smart contracts called "chaincode" that comprise the application logic of the system.
