Threat Model

Network privacy depends on who the adversary is and where they sit. A tool that defeats one adversary can be useless against another. This section defines the Nym threat model as a shared vocabulary, so that every "does this protect me?" question has a precise answer: protect you from whom?

The model has three parts. Read them in order.

• Threat actors — the adversaries, split by vantage point (L1 to L3G). Where each one sits decides what it can see.
• Linkage vectors — the channels through which an adversary attributes or links your requests (V1 to V3), and what closes each.
• Unlinkability properties — the two properties we measure every configuration against (P1 and P2).

With that vocabulary in place, the two-layer model shows how tool choice falls out of the threat model rather than a ranking, and Nym vs other systems compares Nym to VPNs, Tor, I2P, and end-to-end encryption on the same terms.
