It also aims to uncover the dimensions and role of trust, security and privacy alongside the primary Technology Acceptance Model (TAM)-based predictors and their causal relationship with the usersвЂ™ behavior to adopt such BBS. The main objective of this research is to evaluate the user acceptance of a real-life blockchain-based system (BBS) by observing various latent variables affecting the development of usersвЂ™ attitudes and intention to use the system. Despite many extensive studies evaluating the performance of blockchain-based systems, few have focused on usersвЂ™ acceptance of real-life applications. The acceptance of such blockchain-based systems is necessary for the continued use of the services. In the collaborative business environment, blockchain coupled with smart contract removes the reliance on a central system and offers data integrity which is crucial when the transacting parties rely on the shared data. Augmenting the technology acceptance model with trust model for the initial adoption of a blockchain-based system. Cite this article Shrestha AK, Vassileva J, Joshi S, Just J.
