Blockchain Could Help Find Tainted Food
They’re watching what you eat. A group of major grocery stores and food processors, hoping to prevent foodborne illnesses, are trying out a blockchain-based system to track food as it moves along supply chains — and into your digestive tract. The autonomous chunks of code, developed for cryptocurrencies, can potentially unite farmers, distributors, packagers and retailers — now using disparate produce documentation — under a secure digital umbrella that enables quick isolation of contaminated lots. Walmart’s already using a pilot version, suggesting that you might soon be stocking the fridge with encoded comestibles.
