About This Site & Its Operators
Purpose and intended readers
“P2P Explained” is a technical guide whose goal is to make peer-to-peer networking understandable to readers who are not networking specialists. It is aimed at students and engineers interested in web development or infrastructure, people just starting to learn about blockchains or distributed systems, and anyone organizing P2P fundamentals for a university course or an IT certification exam. P2P is often misunderstood through the lens of file-sharing apps, but it is in fact core infrastructure of the modern internet: video conferencing (WebRTC), blockchains, distributed file systems (IPFS), and more. This site aims to make the “why” and the “how” of these technologies intuitive by combining historical context with interactive simulations, as a first step before diving into more specialized material.
What you will find here
Rather than a parade of textbook definitions, this site emphasizes the historical and technical context of why each mechanism became necessary. Diagrams and interactive simulations are used throughout to convey dynamic concepts that text and static images alone struggle to capture. A glossary and FAQ are also provided to help first-time readers avoid getting stuck. The main topics covered are:
- P2P fundamentals: DHTs, BitTorrent, NAT traversal, and gossip protocols: the core mechanisms of the network layer.
- Blockchain-related topics: distributed consensus, DID, multisig, smart contracts, and DApps: the technologies underpinning distributed ledgers.
- Security: attacks on P2P and blockchain networks, such as Sybil and Eclipse attacks, and their defenses.
- Applications: P2P and the metaverse, covering use in games and XR.
- A browser-based distribution simulation, built in-house, that lets you feel P2P scalability hands-on rather than just read about it.
About the operators
This site is run by two people: fog, who has a deep interest in network technology and web front-end development, and Nawashiro, who is active in the decentralized SNS community. Writing the articles and building the simulations is mainly fog’s work, done in TypeScript with no reliance on external rendering or networking libraries. An ongoing goal is to grow the share of content readers can not only read but actually run and verify for themselves.

Development activity
Beyond writing explanations, actually building P2P networks is a central part of this project. As part of tik-choco-lab, a project working toward a decentralized metaverse, I develop mistlib, an open-source, WebRTC-based, Rust-core distributed networking library with a spatial-partitioning (AOI: Area of Interest) synchronization mechanism that divides a large field into regions to narrow each peer’s sync scope. This applies the same ideas behind the DHT and gossip-style synchronization discussed on this site to real-time communication for games and metaverse-style applications. Running the cycle of spec, implementation, and verification myself keeps the articles here grounded in practice rather than purely theoretical.
- I publish browser apps built on mistlib and related tooling (TC Space, TC Town, TC Chat, and others). All run entirely in the browser with nothing to install; the full list is available from tc-home.
- The articles on this site draw on experience gained from designing and implementing these systems myself, reflecting, where relevant, not just the theory but also the pitfalls and design decisions encountered along the way.

Articles are written in original structure and prose while consulting primary sources such as RFCs, official project documentation, and papers. Rather than simple summaries, I cross-check multiple sources and restate how each mechanism works in my own words. Where a number or specification cannot be verified, I deliberately leave it out rather than state it with unwarranted confidence. Content is not left static after publication; it is revisited and updated whenever the technology moves on or an error comes to light. These articles are also written with the help of generative AI, so they may contain mistakes or imprecise statements. If you notice one, I would genuinely appreciate a note via the contact page; I will check it and correct it promptly.
