This paper examines blockchain technology's transformative impact on banking auditing through analysis of implementations across 15 major global financial institutions. The research demonstrates that blockchain reduces audit time by 40-60%, enhances data integrity verification, and enables real-time continuous auditing. Using mixed-methods analysis of performance metrics and case studies from JPMorgan Chase, HSBC, and Deutsche Bank, findings indicate 75% improvement in error detection rates and 35-45% cost reductions. The study provides a comprehensive framework addressing technical challenges, regulatory considerations, and implementation strategies. Results confirm that blockchain's immutable ledger, smart contract automation, and distributed architecture fundamentally improve audit quality dimensions including data verification speed, transaction traceability, and regulatory compliance accuracy. The research contributes empirical evidence supporting blockchain adoption as essential for modernizing banking audit infrastructure and meeting evolving regulatory requirements.
