Specific goal of this work is to present a system that provides full visibility of process\/food certifications, which nowadays are issued by accredited and approved certification bodies (issuers) and delivered and stored in paper version by the several participants (holders) of the supply chain. The system is designed and implemented by combining the latest most innovative and disruptive technologies in the market\u2014Self Sovereign Identity system, Blockchain, and Inter Planetary File System. The crucial aspects that it aims to hit are the storage and access of food\/process certifications, and the proper eligibility verification of these certifications exploiting the concepts of the Self Sovereign Identity-based models. The proposed system, realized by using standards that are WWW Consortium-compatible and the Ethereum Blockchain, ensures eligibility, transparency, and traceability of the certifications along a food supply chain, and could be an innovation model\/idea that the companies that adopt the Open Innovation paradigm might want to pursue.<\/jats:p>","DOI":"10.3390\/fi13120301","type":"journal-article","created":{"date-parts":[[2021,11,29]],"date-time":"2021-11-29T05:23:02Z","timestamp":1638163382000},"page":"301","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":45,"title":["Blockchain and Self Sovereign Identity to Support Quality in the Food Supply Chain"],"prefix":"10.3390","volume":"13","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-5055-9166","authenticated-orcid":false,"given":"Luisanna","family":"Cocco","sequence":"first","affiliation":[{"name":"Department of Mathematics and Computer Science, University of Cagliari, 9124 Cagliari, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9090-7698","authenticated-orcid":false,"given":"Roberto","family":"Tonelli","sequence":"additional","affiliation":[{"name":"Department of Mathematics and Computer Science, University of Cagliari, 9124 Cagliari, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Michele","family":"Marchesi","sequence":"additional","affiliation":[{"name":"Department of Mathematics and Computer Science, University of Cagliari, 9124 Cagliari, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2021,11,26]]},"reference":[{"key":"ref_1","unstructured":"EmergenResearch (2021, November 03).
