ZD Tech: When blockchain tracks food from field to plate

Hello everyone and welcome to ZD Tech, ‘s daily editorial podcast. My name is Clarissa Trill and today I will explain to you why blockchain enters the food supply chain.

In recent years, companies have begun using blockchain technology to verify the origin of products sold in stores and ensure that specifications are met at every stage of the supply chain.

Thus, certain initiatives have emerged, such as Carrefour, which certifies its organic products under its own brand through the blockchain, or Danone, which also uses technology to trace the path of its baby milk.

The confidence of consumers is growing, who are more attentive to the quality and origin of the products they buy in stores. But this is just the tip of the iceberg.

Distributed and transparent ledgers

We will see that this technology contributes primarily to solving the economic, health and environmental problems of the agri-food sector.

Far from being in control of all stages, manufacturers and industrialists see blockchain as a means of having a platform to control the compliance of food products as they move through production chains.

On paper, blockchain seems appropriate: it allows the creation of transparent and distributed ledgers that record useful information in a verifiable and immutable way.

Intervene in the chain

Unlike the more traditional blockchain use case in the financial sector, food blockchain tracks and authenticates the journey of a product to be consumed. This means that the information that the consortium members enter into the register is brought to stabilization, and then disappears in the long term.

Ultimately, from the field to the plate, blockchain is of particular interest in food hygiene compliance. If contamination of a particular product is reported, as sometimes happens, members of the consortium can determine at what level of the chain the contamination occurred in order to intervene more quickly.
