ABSTRACT: Indonesia’s conventional land registration system is prone to data forgery, certificate duplication, and protracted bureaucracy. This study examines the legal reconstruction of blockchain-based digital land registration to strengthen the legal certainty of land rights. The goal is to formulate a legal framework that integrates blockchain technology and identify obstacles and strategies for its implementation. The method used is normative legal research through literature studies with legislative, conceptual, comparative, and policy approaches. The findings show that the characteristics of blockchain (immutability, transparency, traceability) are able to strengthen the integrity of land registration data. Three models of legal recognition are proposed, with the hybrid model considered the most realistic for Indonesia. Obstacles to implementation include legal, institutional, and technical aspects. In conclusion, comprehensive legal reconstruction is a necessity for blockchain innovation to truly strengthen the legal certainty of land rights.
