Extending UTAUT2 Model With Sustainability and Psychological Factors in Adoption of Blockchain Technology for the Digital Transformation of Banks in India

Introduction

Climate issues are still relevant amid the pandemic, and it is now more important than ever to prevent environmental degradation (Huynh, 2020; Huynh et al., 2022; Kovilage, 2020; Liu et al., 2021; Vyas et al. 2023). Most ecological problems are caused by greenhouse gas emissions, primarily from fossil fuels and non-renewable energy sources. One way to promote green banking is to emphasize how crucial it is to link the desire to use online banking with the desire to protect the environment and be happy. Banking is going through a technological revolution because fin-tech companies are getting increasingly competitive and want to offer green banking and sustainable financial services (Mehta et al., 2022). The service sector is a significant part of most developed countries' GDP today (Borghi, 2019). Fin-tech start-ups that use technology to give customers different banking and other financial services have made the big banks have to develop new ideas to stay competitive. Intelligent decision models used data mining in the 1990s to improve the way standard bank functions worked for insurance (Anand, Patrick, Hughes, and Bell, 1998). “Industry 4.0” is a new wave of disruptive technologies that have recently appeared in our society and spread to several industries (Hou et al., 2020; Chang et al., 2019). Industry 4.0 includes a wide range of technologies, such as artificial intelligence (AI), blockchain, and the internet of things (IoT), as well as cloud computing, 3D printing, and cyber-physical systems (CPS) (Chang et al., 2020). ATMs have replaced human tellers for repetitive cash withdrawals and deposits, reducing the need for human help. (Huang & Rust, 2018). Modelling with neural networks showed that the perceived ease of use is essential for online banking to be accepted in developing countries like India.
