Despite the promising capability to help organisations inaugurate their trusted supply chains, blockchain technology has not been widely adopted due to several adoption inhibitors. As opposed to prior blockchain literature that mostly focused on the direct effect of technology-related factors, this research-in-progress paper offers a new perspective of holistic examination of key determinants of an organisation’s intention to adopt blockchain. The paper also develops a conceptual model of blockchain adoption for supply chain context grounded on the integration of the technology-organisation-environment (TOE) and the extended valence frameworks. Specifically, three technological factors, two organisational factors, and two environmental factors directly influence an organisation’s intention to adopt blockchain. Moreover, trust influences blockchain adoption intention indirectly through performance expectancy and risk of system security. The study offers a contribution to academics regarding the critical determinants of blockchain deployment for establishing trusted supply chains.
