Blockchain technology in the beef breeding sector

The initial observation is that there is a loss of information, mainly due to insufficient collaboration between professionals of the beef industry, who only partially communicate traceability information amongst themselves. The result is a loss of information at each stage of the chain, and therefore a loss of added value for the product vis-à-vis the final consumer. This insufficient transparency does not create the conditions necessary to establish a relationship of trust with the final consumer who is obliged to “believe” the partial information communicated by the actor at the end of the chain (i.e. the distributor in most cases);
This article describes how blockchain technology can respond to this problematic. The principle is to establish a decentralized architecture associated with blockchain technology. Indeed, loss or falsification of information is technically impossible in a blockchain system with a satisfying level of decentralization. In practice, multiple entry points and an electronic signature system allow each actor of the chain to provide and certify information that he/she disposes of. The system allows actors to better guarantee the integrity of the data and their origin and thus to self-regulate. For example, a processor could directly access information coming from the farm, without having to go through an intermediate party such as the slaughterhouse. In addition, the blockchain makes it possible to move from a “declarative” system of information to a system of information “certified” by each link in the chain. At the end of the chain, the consumer can, thanks to a QR code, access different sources of complete and certified information provided directly by each of the actors of the chain, from the breeder to the final distributor via the slaughterhouse and the processor.
