Blockchain technology has become significant for financial sectors, especially digital payment systems, offering enhanced security, transparency, and efficiency. However, there is limited research on the factors influencing user trust in and acceptance of blockchain adoption in digital payment systems. This systematic review provides insight into the key factors impacting consumers’ perceptions and behaviours towards embracing blockchain technology. A total of 1859 studies were collected, with 48 meeting the criteria for comprehensive analysis. The results showed that security, privacy, transparency, and regulation are the most significant factors influencing trust for blockchain adoption. The most influential factors identified in the Unified Theory of Acceptance and Use of Technology (UTAUT) model include performance expectancy, effort expectancy, social influence, and facilitating conditions. Incorporating a trust and acceptance model could be a viable approach to tackling obstacles and ensuring the successful integration of blockchain technology into digital payment systems. Understanding these factors is crucial for creating a favourable atmosphere for adopting blockchain technology in digital payments. User-perspective research on blockchain adoption in digital payment systems is still insufficient, and this aspect still requires further investigation. Blockchain adoption in digital payment systems has not been sufficiently conducted from the user’s perspective, and there is a scope for it to be carried out. This review aims to shed light on the factors of trust in and acceptance of blockchain adoption in digital payment systems so that the full potential of blockchain technology can be realised. Understanding these factors and their intricate connections is imperative in fostering a conducive environment for the widespread acceptance of blockchain technology in digital payments.

Blockchain is a secure, digital ledger that enables faster transactions, reduces fraud, lowers costs, and enhances transparency. The blockchain is capable of changing the face of digital payments by providing greater opportunities for transformation. Consumer acceptance in emerging markets such as Bhutan depends on a number of key factors. This paper explores the impact of performance expectancy, effort expectancy, social influence, and facilitating conditions on consumer acceptance of blockchain-based digital payment systems in Bhutan. Sustained by the Unified Theory of Acceptance and Use of Technology (UTAUT), the study uses PLS-SEM to analyze survey data from 302 respondents. The results show that performance expectancy, the expectation of blockchain’s usefulness, is the most influential factor determining customer acceptance. Effort expectancy and facilitating conditions are equally important. Social influences, although rather marginal, play an important role in Bhutan’s collectivist culture. The paper sheds light on factors for consumer acceptance of blockchain adoption. The findings add to the literature on blockchain adoption in burgeoning economies and provide the foundation for further research on blockchain adoption in multi-cultural contexts.
