This study evaluates the impact of blockchain technology on stakeholder collaboration in sustainable housing development (SHD) in Angola. It focuses on overcoming barriers to achieving Sustainable Development Goal (SDG) 11.1, which seeks affordable and environmentally friendly housing in developing countries by 2030, thereby promoting sustainable development and urban growth through innovative building technologies.
A mixed-methods approach was used, integrating the decision-making trial and evaluation laboratory-analysis of network processes (DEMATEL-ANP) model and the technology-organization-environment (TOE) framework to assess blockchain’s influence on stakeholder collaboration in SHD in Angola. Data were collected from 34 Angolan experts between May and June 2024, using a questionnaire survey to convert subjective assessments into numeric values, providing actionable insights to enhance collaboration in SHD initiatives.
The findings indicate that blockchain technology can significantly improve transparency, enhance data integrity and streamline transactions among stakeholders, addressing major barriers to collaboration. Additionally, organizational readiness, such as top management support, staff training and favorable government policies, is critical for maximizing blockchain adoption.
The study is limited to the context of Angola and may not be generalizable to other regions without further research.
This research offers valuable insights for policymakers and industry leaders in Angola and other least developed countries, emphasizing opportunities to leverage blockchain technology for SHD. By addressing challenges in stakeholder collaboration and information sharing, the study provides guidance on using blockchain to enhance transparency and efficiency in SHD projects.
