Blockchain-Based Secure Data Sharing Framework for Smart Cities

Abstract

Procurement of blockchain technology by smart cities creates new possibilities to strengthen both security and privacy and transparent data systems in urban areas. The study analyzes blockchain-based secure data-sharing frameworks for smart cities through interviews with experts who belong to urban planning, cybersecurity, IoT engineering and city management fields. The authors performed interviews together with assessing established blockchain projects in smart cities to recognize both implementation obstacles and prospective features of blockchain data security systems. The research demonstrates blockchain technology provides many useful features but multiple obstacles limit its actual deployment. The adoption of blockchain for data sharing faces multiple obstacles which start with expensive startup expenses as well as standardization issues and regulatory obstacles. This study displays the necessity of public-private sector stakeholder coordination as well as the requirement to establish regulatory frameworks and provide urban population education. The integration of blockchain into urban data-sharing systems receives thorough analysis from different smart cities' interviews and case studies that provides this framework for future implementation. The research helps expand existing blockchain knowledge about smart city evolution by delivering essential guidelines to both policymakers and city administrators.
