Blockchain for the Secure Management of Digital Identities in Real Estate Platforms

Abstract

This dissertation studies and develops a digital system based on blockchain technology and smart contracts in order to propose a modern solution that improves the reliability of digital transactions and enhances transparency and security. The work is motivated by the limitations of traditional systems, such as centralization, difficulty in tracing operations, and the risk of data manipulation, which require more advanced and effective approaches. The study first presents the theoretical foundations of the adopted technologies, then de signs and implements a practical model showing how blockchain can be used to secure and record operations in a decentralized manner. Special attention is given to the role of smart contracts in automating procedures and reducing manual intervention, thereby improving the overall system performance. The results show that the proposed solution offers a more secure, transparent, and scalable architecture than conventional approaches, with potential for future extensions and additional functionalities.
