Impact of Blockchain Technology on Audit Quality and Efficiency of Large Corporations in Nigeria

Abstract

The auditing profession faces increasing challenges related to data complexity, transparency, and efficiency, necessitating the adoption of innovative technologies. This study empirically investigates the impact of blockchain technology on audit quality and efficiency within large corporations, focusing on the specific roles of immutability, transparency, smart contracts, and data security. Drawing on the Technology-Organization-Environment (TOE) framework, Diffusion of Innovations Theory, and Transaction Cost Economics, the research posits that these blockchain characteristics significantly enhance audit outcomes. A survey research design was employed, collecting data from 294 auditors and financial professionals in large corporations and audit firms globally that are utilizing or exploring blockchain technology. Data were analyzed using descriptive statistics, Pearson Product-Moment Correlation, and Multiple Regression Analysis. The findings reveal that all four independent variables, immutability, transparency, smart contracts, and data security, are significant positive predictors of both audit quality and audit efficiency. Specifically, immutability emerged as the strongest predictor for audit quality (β=0.450, p<0.001), emphasizing its role in enhancing the reliability of audit evidence. Transparency was identified as the most influential factor for audit efficiency (β=0.400, p<0.001), highlighting its ability to streamline evidence gathering and reduce information asymmetry. The regression models explained a substantial portion of the variance in audit quality (R2=0.783) and audit efficiency (R2=0.740). This study concludes that while blockchain technology holds significant potential for transforming auditing, its actual impact is contingent on the strategic leveraging of its core characteristics. The results reinforce the theoretical frameworks, suggesting that integrating blockchain's inherent strengths into audit methodologies can lead to a more proactive, continuous, and comprehensive assurance function, thereby fostering greater trust and transparency in financial reporting for large corporations. Recommendations include developing specialized training programs for auditors, initiating pilot projects, and designing audit-friendly blockchain platforms.
