Fast and Free: A Decentralized Peer-to-Peer File Sharing System

Peer-to-peer (P2P) file sharing systems have become increasingly popular in recent years, allowing users to share files efficiently and effectively. However, most existing P2P systems rely on centralized servers, which can lead to bottlenecks, single points of failure, and limitations in scalability. In this paper, we propose a decentralized P2P file sharing system that is both fast and free. Our system utilizes a distributed hash table (DHT) to enable efficient file searching and retrieval, while also ensuring that users can share files without relying on centralized servers.
