Cover Story: Increased consumer requirements for quality, safety, and traceability of goods, especially in food supply chains, has accelerated the implementation of blockchain during the COVID-19 pandemic. The right choice of blockchain software in agriculture is a complicated task and an important prerequisite for successful deployment. In this study, we propose a conceptual framework for group multicriteria selection of blockchain software in a fuzzy environment according to organization needs and experts’ judgements. The applicability of the new framework has been verified through an illustrative example for ranking blockchain systems. The evaluations of compared alternatives were calculated by using a fuzzy measurement of alternatives and ranking according to the compromise solution (MARCOS) model with different sets of weight coefficients.
