This sophisticated technology can provide a decentralized, transparent, and secure environment for organizations and businesses. This review article discusses the adoption of blockchain in the ports and shipping industry to support digital transformation. It also explores the integration of this technology into the current ports and shipping ecosystem. Besides, the study highlighted the situation of the supply chains management in ports and shipping domain as a case study in this field. The investigated studies show that blockchain can be integrated into processes such as financial and document workflow. This review contributes to research by focusing on the adoption of blockchain in the ports and shipping industry to support digital transformation. It also aims to understand the existing port practice and map it with current tendencies based on blockchain. This study gives insight analysis to incorporate blockchain technology into ports and shipping processes globally.<\/jats:p>","DOI":"10.1515\/jisys-2021-0131","type":"journal-article","created":{"date-parts":[[2021,12,8]],"date-time":"2021-12-08T08:12:04Z","timestamp":1638951124000},"page":"55-69","source":"Crossref","is-referenced-by-count":13,"title":["Comparative analysis of blockchain technology to support digital transformation in ports and shipping"],"prefix":"10.1515","volume":"31","author":[{"given":"Dimah H.","family":"Alahmadi","sequence":"first","affiliation":[{"name":"Department of Information Systems, Faculty of Computing & Information Technology, King Abdulaziz University , Jeddah , 21431 , Kingdom of Saudi Arabia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Fatmah Abdulrahman","family":"Baothman","sequence":"additional","affiliation":[{"name":"Department of Information Systems, Faculty of Computing & Information Technology, King Abdulaziz University , Jeddah , 21431 , Kingdom of Saudi Arabia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mona M.","family":"Alrajhi","sequence":"additional","affiliation":[{"name":"Department of Information Systems, Faculty of Computing & Information Technology, King Abdulaziz University , Jeddah , 21431 , Kingdom of Saudi Arabia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Fatimah S.","family":"Alshahrani","sequence":"additional","affiliation":[{"name":"Department of Information Systems, Faculty of Computing & Information Technology, King Abdulaziz University , Jeddah , 21431 , Kingdom of Saudi Arabia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hawazin Z.","family":"Albalawi","sequence":"additional","affiliation":[{"name":"Department of Information Systems, Faculty of Computing & Information Technology, King Abdulaziz University , Jeddah , 21431 , Kingdom of Saudi Arabia"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"374","published-online":{"date-parts":[[2021,12,4]]},"reference":[{"key":"2025120523411402606_j_jisys-2021-0131_ref_001","unstructured":"Poongodi M, Malviya M, Hamdi M, Vijayakumar V, Mohammed MA, Rauf HT, et al. 5G based Blockchain network for authentic and ethical keyword search engine.
