Walmart has opened its Food Safety Collaboration Center in Beijing and announced a partnership with IBM and Tsinghua University to improve food safety through blockchain technology. The initiative is designed to strengthen traceability across the food supply chain, increase operational transparency, and provide better safeguards for consumers.
Using blockchain to modernize food traceability
Tracking food quality through traditional supply chains has long been difficult. Contamination cases, poor ingredients, and uninspected crops have led to repeated recalls and broader concerns about how food is monitored from production to retail. The partners behind the new Beijing initiative argue that these issues cannot be solved by external regulation alone and that stronger controls need to be built directly into production and manufacturing processes.
The collaboration is focused on building a model for food traceability, supply chain transparency, and audibility. To do that, the group plans to use the Hyperledger architecture developed with leadership from IBM and the Linux Foundation. Under this framework, food-related data can be recorded in a distributed ledger environment, creating a digital trail that includes information such as storage temperatures, expiration dates, farm origin details, batch numbers, and other key supply chain records.
Hyperledger-based records and network consensus
According to IBM, information entered at each stage of the supply chain would be shared across the blockchain network and validated by participating businesses. Once agreement is reached, the data becomes a permanent record of the process. This approach is intended to reduce the inefficiencies of paper-heavy systems while improving confidence in the accuracy and integrity of supply chain information.
Frank Yiannas, Walmart’s Vice President of Food Safety, said the company sees greater transparency as a priority for customers and wants to explore whether blockchain can serve as a more effective traceability solution. IBM Senior Vice President Bridget van Kralingen said advanced technologies have transformed many parts of modern life, but food traceability and secure food supply chains have lagged behind, making this collaboration a globally significant step.
Benefits for retailers and consumers
The partners also see practical value for retailers. A distributed ledger could help merchants identify shelf-life issues, improve store-level product management, and react more quickly if a specific batch needs to be isolated. Each participant brings a different strength to the project: Walmart contributes expertise in food safety, logistics, and supply chains; IBM provides blockchain and enterprise technology capabilities; and Tsinghua University adds academic research focused on food safety.
Professor Chai Yueting of Tsinghua University said China’s rapid growth has created greater challenges in ensuring that food sold in the country is safe to eat. The Beijing initiative aims to improve food quality oversight through more efficient monitoring and data handling, replacing cumbersome traditional processes. More broadly, the project highlights how blockchain is being explored beyond finance as a tool for quality assurance in real-world industries.
