As of now, most companies are using secure accounting information systems to conduct their financial management. This research work gives a detailed analysis of the importance of incorporating blockchain into these systems in order to enhance the level of transparency in financial reporting and the efficiency of auditing. Four hypotheses are formulated and tested and the regression and mediation models are developed to examine how the blockchain-enabled secure accounting information systems influence the reporting transparency and audit performance. Regression findings indicate that the two independent variables have coefficients of 0.796 and 0.385 respectively, and they are statistically significant(p<0.001), indicating that blockchain adoption can play a vital role towards enhancing the transparency of corporate financial reporting and audit effectiveness. As such, H1 and H2 are confirmed. The mediation analysis also affirms the suggested connections: the F-statistics are 15.34 and 11.96, both significant at 0.000, which means that information sharing is a mediator in the relationship between blockchain technology, reporting transparency, and audit efficiency. Hence, H3 and H4 are also validated. On the whole, the current paper proves that blockchain technology has a significant place in enhancing financial reporting transparency and the quality of auditing and provides valuable assistance to the theoretical research and practice implementation.
