A Comprehensive Survey on Blockchain-Based Land Registry Systems: Dual-Signature Approaches for Secure and Transparent Property Management

Blockchain has the potential to revolutionize land administration by ensuring transparency, efficiency, and accountability. Dual-signature Proof-of-Authority systems represent a practical evolution of blockchain’s capabilities, blending decentralization with necessary government oversight. Through the analysis of existing global pilots, this paper underscores the importance of technical design, policy alignment, and public participation in achieving a secure and scalable blockchain-based land registry ecosystem. Future work should focus on developing hybrid frameworks integrating blockchain, AI, and GIS technologies to achieve a seamless, verifiable, and citizen-centric land governance system.
