libp2p Protocol Stack & BitTorrent Protocol Deep Dive

Mon, 08 Nov 2021 00:00:00 +0000

Building on our understanding of P2P core principles and Kademlia DHT, we now dive into two production-proven P2P protocols — the libp2p protocol stack and BitTorrent. They represent two different design philosophies: a general-purpose P2P framework versus a specialized file distribution protocol.

libp2p Modular Architecture

libp2p is the networking layer behind IPFS and Filecoin, providing a modular toolkit for building P2P applications. Its design philosophy is “pluggable network protocol stack for P2P applications” — developers compose transport, security, multiplexing, and application layers like building blocks.

Rust P2P Development: From Ping to Gossipsub

Mon, 22 Aug 2022 00:00:00 +0000

Rust’s ownership model and zero-cost abstractions make it an ideal language for implementing P2P network protocols. The Rust implementation of libp2p (rust-libp2p) provides a complete protocol stack from transport to application layer.

Go P2P Development: From Basics to PubSub

Mon, 05 Jun 2023 00:00:00 +0000

Go’s simple concurrency model and fast compilation make it a popular choice for P2P network development. go-libp2p is one of the most complete libp2p implementations and is widely used in large projects like IPFS (Kubo).
