Decentralized applications have garnered significant attention in recent years, driven by the rise of blockchain and cryptocurrencies and a growing awareness of data privacy issues associated with centralized control by a few companies. An introductory tutorial explores building a simple peer-to-peer application using Rust and the libp2p library, which provides a modular framework for creating decentralized networks. The tutorial guides readers through creating a cooking recipe application with features such as creating, publishing, and listing recipes across a network of peers. It demonstrates using Rust's async capabilities, along with libp2p protocols, to facilitate secure communication and data exchange between peers. The tutorial also highlights the integration of various components like Tokio for asynchronous runtime, Serde for JSON handling, and mDNS for peer discovery. The approach encourages a design and build methodology distinct from traditional web applications, emphasizing the adaptability and maturity of libp2p in developing decentralized applications.
