P2P file sharing systems have been extensively studied in the literature. Early systems, such as Napster, used centralized servers to manage file sharing. Later systems, such as BitTorrent, introduced distributed architectures, but still relied on centralized trackers. Recent systems, such as InterPlanetary File System (IPFS), have explored decentralized architectures, but often require users to pay for storage and bandwidth.
