This study examines the determinants of Blockchain adoption, with a specific focus on the mediating role of attitude within an extended Technology Acceptance Model (TAM) framework. The proposed model integrates social influence, perceived usefulness, and perceived ease of use as key antecedents shaping user attitude, which subsequently affects Blockchain adoption behavior. A quantitative research design was employed to test the hypothesized relationships. Primary data were collected from 196 employees working in service sector organizations across banking, healthcare, supply chain, and education industries in the United Arab Emirates. Convenience sampling was used for respondent selection. The data were analyzed using SmartPLS software through Partial Least Squares Structural Equation Modeling (PLS-SEM), enabling simultaneous assessment of direct and indirect relationships among constructs. The empirical findings highlight attitude as a central mediating mechanism in the Blockchain adoption process. The results indicate that cognitive and social factors collectively contribute to the formation of positive user attitudes, which in turn significantly influence adoption behavior. The study further demonstrates the applicability of the extended TAM framework in explaining Blockchain adoption in organizational settings. This research contributes to the existing literature by extending TAM to emerging Blockchain technology and providing empirical evidence from a developing economy context. The findings offer practical insights for managers and policymakers aiming to enhance user acceptance and successful implementation of Blockchain-based systems in service sector organizations.
