Blockchain in the agri-food chain: Evolution, revolution or hype?

This case describes (in a didactic and simplified manner) blockchain technology and how it works, its characteristics, advantages, and potential use cases, specifically in the food chain. It then outlines some reservations about the adoption and use of this technology, proposing a discussion about its prospective value: Is blockchain technology really revolutionary? Conversely, is it merely an interesting technology that will help improve some business processes without bringing about a revolution? Is it just an overhyped illusion that will fade over time and be relegated to a few niche applications?
