About The Onion Encyclopedia

This article is a related reference. The main article in this collection is Nexus Market.

The Onion Encyclopedia is a community-maintained reference for darknet markets, Tor protocol details, cryptographic primitives, and the cultural surface area of the post-Hydra Tor economy. The project is independent, volunteer-run, and published under CC BY-SA 4.0.

Editorial scope

Articles cover marketplaces with at least 90 days of operational history, the protocols and tools they rely on (Tor, Monero, PGP), and the cryptographic primitives underpinning escrow and signing. The encyclopedia does not cover product information, vendor profiles, or anything that would constitute facilitation rather than reference.

Editorial policy

• Citations are mandatory. Every factual claim is sourced; sources can be signed PGP announcements, independent reporting, public protocol specifications, or peer-reviewed cryptographic literature.
• Living documents. Articles are revisited on a monthly cadence at minimum. Out-of-date articles are flagged in-banner.
• No marketplace endorsement. Comparison tables present feature presence as observed; the encyclopedia takes no position on which marketplace is “best”.
• Reproducibility. The article corpus, its revision history, and its citation graph are mirrored to a content-addressed store; readers can verify every revision against a signed manifest.

Project history

The encyclopedia was founded in February 2024 by a small group of long-time darknet observers who wanted a reference that survived individual marketplace lifetimes. The project has remained continuously maintained since launch, with monthly editorial committee meetings logged in the public minutes archive.

How to contribute

Editorial contributions are accepted exclusively through the project's onion mirror under PGP signature. The contribution flow, style guide, and citation requirements are documented in CONTRIBUTING.md in the project repository.
