Blockchain-Enabled Tokenization for Transparent and Inclusive Financing of Sustainable Infrastructure Projects

The persistent financing gap in sustainable infrastructure remains a major barrier to achieving the United Nations Sustainable Development Goals (SDGs), as traditional financing models often suffer from limited transparency, high entry barriers, and restricted investor access. This study explores the integration of Blockchain technology and tokenization as innovative mechanisms to address these challenges by enhancing transparency, inclusivity, and investment accessibility. Utilizing a mixed-methods approach, data were collected through interviews with financial experts, Blockchain developers, and project managers, alongside surveys involving 100 respondents from the finance and infrastructure sectors across multiple regions. The analysis combined thematic coding using NVivo and statistical assessment of Likert scale responses to evaluate transparency, trust, accessibility, and perceived security risks. Results show that Blockchain significantly improves transparency (mean score 4.2) and trust (4.0), while tokenization facilitates fractional ownership and broadens access to infrastructure investment (4.1). Although moderate concerns about security remain (score 3.3), the strong interest in tokenized investment, especially among developers and investors, reflects a growing readiness for adoption. The novelty of this research lies in its comprehensive examination of the combined application of Blockchain and tokenization for sustainable infrastructure financing a synergy that is rarely addressed in existing literature. By proposing a decentralized, secure, and inclusive financing model, this study offers valuable insights for policymakers, practitioners, and fintech stakeholders seeking to close the infrastructure financing gap and promote long-term sustainability.
