How can blockchain help to achieve a sustainable agrifood sector? Blockchain offers many opportunities for improving transparency, efficiency, competitiveness of agrifood and the position of farmers in the data value chain. The playing field of blockchain spans the domains of automation, data science, and data economy. To realise a good use case requires close collaboration of people from all three sub-domains. For this report we studied more than 30 blockchain use cases and platforms in and outside of the Netherlands. Within the programme ‘Blockchain for Agrifood’, software applications have been built for three use cases: FarmDataWallet, Flori-Chain and AGF-Chain. Experiences with these use cases have been used to identify the challenges and best practices.
