The objective of this paper is to explore the timing and methods by which organizations adopt blockchain technology (BT) to enhance both supply chain integration (SCI) and overall supply chain performance. The study grounded its theoretical framework in the dynamic capabilities perspective. Employing a quantitative methodology, data collection involved a structured questionnaire administered to a sample of 160 participants from various manufacturing firms in Bangladesh. To evaluate the formulated hypotheses, Structural Equation Modeling (SEM) analysis was performed using WarpPLS7.0 software. The results suggest a significant and positive effect of BT on both SCI and supply chain performance. Furthermore, the findings support the hypothesis that SCF plays a positive and significant moderating role in the relationship between BT and both SCI and supply chain performance. This study addresses a recognized gap in applying BT to enhance both supply chain integration and performance within a comprehensive context that includes the moderating role of supply chain flexibility. By demonstrating the positive effects of BT, organizations can better understand how to leverage this technology to improve operational efficiency and competitive advantage
