Contributing factors to food spoilage (temperature, time from harvest to shelf, varieties, lighting, shipping time, etc) are being tracked through Walmarts pilot project with IBM's Blockchain tech. By revamping their data management processes across their network of farmers, brokers, distributors, processors, retailers, regulators, and consumers they are creating a real-time analysis and ledger of all elements of their supply. Along this chain, they can track for elements that lead to spoilage, waste, safety issues, demand, etc.
