The right choice of blockchain software is a complicated task and an important prerequisite for successful deployment. In this study, we propose a conceptual framework for group multi-criteria selection of blockchain software in fuzzy environment according to organization needs and experts\u2019 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 measurement of alternatives and ranking according to the compromise solution (MARCOS) method. The robustness of the new framework was proven by sensitivity analysis in which two (crisp and fuzzy) MARCOS models with two different sets of weighting coefficients were compared.<\/jats:p>","DOI":"10.3390\/computers10100120","type":"journal-article","created":{"date-parts":[[2021,9,24]],"date-time":"2021-09-24T20:15:32Z","timestamp":1632514532000},"page":"120","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":21,"title":["Blockchain Software Selection as a Fuzzy Multi-Criteria Problem"],"prefix":"10.3390","volume":"10","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-7504-8576","authenticated-orcid":false,"given":"Galina","family":"Ilieva","sequence":"first","affiliation":[{"name":"Department of Management and Quantitative Methods in Economics, University of Plovdiv Paisii Hilendarski, 4000 Plovdiv, Bulgaria"},{"name":"Intelligent Systems Department, Institute of Information and Communication Technologies, 1113 Sofia, Bulgaria"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5877-3098","authenticated-orcid":false,"given":"Tania","family":"Yankova","sequence":"additional","affiliation":[{"name":"Department of Management and Quantitative Methods in Economics, University of Plovdiv Paisii Hilendarski, 4000 Plovdiv, Bulgaria"}]},{"given":"Irina","family":"Radeva","sequence":"additional","affiliation":[{"name":"Intelligent Systems Department, Institute of Information and Communication Technologies, 1113 Sofia, Bulgaria"}]},{"given":"Ivan","family":"Popchev","sequence":"additional","affiliation":[{"name":"Intelligent Systems Department, Institute of Information and Communication Technologies, 1113 Sofia, Bulgaria"}]}],"member":"1968","published-online":{"date-parts":[[2021,9,24]]},"reference":[{"key":"ref_1","unstructured":"Amir, A.
