When the network you depend on is not always there.
What it is
EdSSA Nano in one paragraph.
EdSSA Nano is the base protocol — and the first implementation of Structural Authentication, the paradigm covered by our patent application "Decentralised Stateless Structural Authentication" filed at PRH (Helsinki) on 1 May 2026, a European-jurisdiction filing with PCT international extension planned within the priority year. Two parties bootstrap once via a post-quantum handshake, then keep authenticating each other autonomously — through link drops, satellite handoffs, and multi-day disconnects — without ever calling a central authority again.
When you need it
Three signals you should look at this tier.
When a per-request round-trip to a credential authority is unaffordable.
When the device you ship today must still authenticate securely in 2045.

Nano is the foundation. Fleet, Swarm, Relay, Edge, and Orbit compose on top of it. Most deployments use two or three tiers together.
Nano is the foundation every other tier builds on. Fleet adds horizontal scale. Swarm adds threshold-tolerant multi-member identity. Relay adds heterogeneous-capability topologies. Edge adds line-rate validation. Orbit adds physical-event-coupled state.
Industries served
Where this tier earns its keep.
DRONES
Authentication that survives jamming, mesh disconnects, and 50,000-unit swarm scale.
SATELLITES
Inter-satellite links that authenticate without ground anchor.
INDUSTRIAL-EDGE
Twenty-five-year device lifetime, intermittent backhaul, regulatory tailwind.
MEDICAL IMPLANTS
Authenticated firmware updates, hardware-bound identity, twenty-year device lifetime.
