Explore the fundamentals of decentralized peer-to-peer networks in this 15-minute conference talk from Conf42 Cloud Native 2025. Begin with an introduction to P2P networks and their key features, then examine the essential components that make up these distributed systems. Learn about P2P protocols and how peer discovery and routing mechanisms enable nodes to find and communicate with each other across the network. Understand transport mechanisms and NAT traversal techniques that allow peers to connect despite network barriers. Discover popular P2P network implementations through detailed examinations of IPFS (InterPlanetary File System), the Fluence Network Protocol, and libp2p - a modular network stack for building P2P applications. Gain practical insights into how these technologies enable decentralized communication, file sharing, and distributed computing without relying on centralized servers or infrastructure.
