This research was performed aiming for investigating the relation between blockchain technology and its dimensions with regard to block, hash, information, and timestamp vis-à-vis the efficiency of internal financial systems in Jordanian commercial banks. Using a descriptive analytical approach, the study considered all 12 major Jordanian banks as the community. It distributed 300 questionnaires to a wide range of banking professionals, such as financial system analysts, IT specialists, and senior executives. Most responses were great, with 265 questionnaires retrieved for analysis. The statistical tests are done using SPSS software. The result indicated that due to the effective use of blockchain technology, the operational efficiency improved significantly. These findings imply that every single aspect of blockchain technology contributes uniquely to enhancing the efficiency, safety, and integrity of all financial transactions. Given this tremendous growth in the development of finance technologies, the study goes on to recommend that Jordanian commercial banks should keep investing in blockchain technology so as not to be at a disadvantage in competing with other banks, and also to take full advantage of improved security in transactions to effectively respond to customers and regulatory demands.
