Without a read capability, no one can tell which messages belong together, and sender and reader need not be online at the same time. That second property is the only reason Pigeonhole stores anything. Our paper, <a href="https://arxiv.org/abs/2501.02933">Echomix: a Strong Anonymity System with Messaging</a>, and <a href="https://katzenpost.network/docs/pigeonhole_explained/">Understanding Pigeonhole</a> have the details. This post treats Pigeonhole as an abstraction that does not depend on the network beneath it: what it is, what it guarantees, what we build with it, and the two networks it now runs on.</p>
