Blockchain adoption in e-commerce: The role perceived security - privacy and trust

This study examines the factors influencing blockchain technology adoption in e-commerce, with particular emphasis on the roles of security, privacy, and trust. Drawing on the extended Technology Acceptance Model (TAM), the proposed research model is tested using partial least squares structural equation modelling (PLS-SEM) based on 311 valid survey responses collected in Vietnam. The results indicate that perceived security and privacy positively affect perceived ease of use, perceived usefulness, and, most notably, trust in blockchain technology. Trust and perceived usefulness are found to positively influence attitudes toward blockchain adoption, while perceived ease of use has no significant effect. Furthermore, positive attitudes significantly promote the adoption of blockchain technology in e-commerce. These findings offer managerial implications for enhancing security, strengthening user trust, and advancing blockchain adoption in digital transaction environments.
