A Review on the Disk Space Rental Systems

– This review explores new ways to store files using blockchain instead of traditional cloud services. We examine four systems: one that manages files automatically with smart contracts, another that lets people rent out unused storage space (like Airbnb for hard drives), a third that connects users directly for secure file sharing, and a fourth designed for areas with poor internet. These systems avoid relying on big companies by spreading data across shared networks. They use blockchain to track transactions and smart contracts to enforce rules without middlemen. Users earn rewards for sharing spare storage, while encryption and unique file codes keep data safe. Challenges remain, such as slow speeds, high costs, and the need for simpler tools. New fixes, like AI helpers and faster networks, aim to solve these issues. Together, these systems show how people can control their own data, reducing risks like hacking or outages. This shift could make the internet more open and fair, where privacy and access work together, not against each other.
