Design of a Modular and Privacy-Aware Land Registration System on Ethereum

Abstract

Conventional land registration systems are often slow, opaque, and susceptible to fraudulent activities due to centralized control, intermediaries and manual verification. This paper proposes a decentralized framework based on blockchain technology to enhance transparency, security, and efficiency in property registration. The system employs smart contracts to automate ownership transactions and ensures user privacy through cryptographic techniques that verify identity without revealing personal data. Property-related documents are stored securely using a distributed file system, while the network’s validation process operates through an energy-efficient consensus model. An intuitive web interface allows secure interaction and real-time updates through digital wallets. Performance testing confirms the system’s scalability, responsiveness, and resistance to data tampering. This approach offers a promising foundation for modernizing land record systems and can be adapted for adoption by public institutions worldwide.
