21wiki is a Bitcoin knowledge base grounded in the immutable 21ideas.org source library (articles, books, and series) and fundamental Bitcoin-only materials organized into a navigable map.

About the project

21ideas.org is a Bitcoin-only education project. Over time it accumulated a large source library: books, long-form series, practical guides, and conceptual explainers across economics, protocol, history, privacy, and security.

This wiki does not replace the original materials. It is a structured map and entry point: if a topic clicks, follow the links and read the primary sources referenced by each page.

About quality

Each page includes YAML frontmatter metadata:

  • quality: "synthesized" — a topic distilled from multiple sources
  • quality: "reference" — a description of a specific source (book, series)
  • completeness: "high" / "medium" / "low" — how fully the topic is covered

Pages marked completeness: "medium" or "low" can be expanded as more sources are ingested.

In Obsidian, use:

  • Graph view — a visual map of connections between pages
  • Backlinks — what links to the current page
  • wikilinks — navigation between articles
  • Dataview (plugin) — query pages by tags and metadata
