Abstract: In the era of exponential digital data growth, the Decentralized Storage Rental System addresses critical challenges in data management within a context defined by increasing volumes of information, cybersecurity threats, and limitations of traditional centralized storage infrastructures. The widespread utilization of digital assets demands innovative approaches to guarantee data security, integrity, and accessibility. This project systematically analyzes these challenges and proposes an advanced solution that leverages blockchain technology and a network of decentralized storage nodes. By adopting this innovative approach, the system provides users with a seaamless experience in renting storage space, uploading, and accessing data securely. Through the implementation of smart contracts, the system ensures transparent and reliable transactions, while the decentralized storage nodes guarantee data availability and resilience against potential failures. In conclusion, the Decentralized Storage Rental System not only addresses the existing challenges in data management but also offers a glimpse into the future of secure and decentralized data storage solutions.
