This quantitative study is centered around small and medium-sized enterprises (SMEs) to explore the potential of blockchain technology in fostering green entrepreneurship for sustainable development. Using a structured questionnaire, data were collected from 160 respondents to assess constructs such as Sustainability Orientation (SO), Sustainability Attitude (SA), Social Perception (SP), Intention to Use (IU), and Green Innovation (GI). Structural equation modeling (SEM) was employed to analyze the proposed correlations among these constructs. The study demonstrates the model's effectiveness in capturing sustainability-related dimensions, as evidenced by high loadings and robust reliability and validity metrics. Cohen's f2 indicator highlights medium effects, particularly for Social Perception, Sustainability Attitude, and Sustainability Orientation on Green Innovation and Intention to Use. Additionally, Stone-Geisser's Q2 values underscore the predictive relevance of endogenous variables. Overall, the results advance our knowledge of how blockchain technology might promote sustainable growth and green entrepreneurship.
