When some members of your swarm have richer connectivity than others.
What it is
EdSSA Relay in one paragraph.
EdSSA Relay handles operational realities where not every node has the same capability. Some nodes have satellite uplink; some are line-of-sight only. Some have abundant compute; some are battery-budgeted. Relay role-tiers protocol behaviour and treats multi-hop authentication as part of the protocol rather than a layer on top.
When you need it
Three signals you should look at this tier.
When authentication must traverse multiple hops without weakening at each hop.
When the network topology itself is part of what needs authenticating.
How it composes

Orbit

Nano is the foundation. Fleet, Swarm, Relay, Edge, and Orbit compose on top of it. Most deployments use two or three tiers together.
Relay extends Swarm with heterogeneous-capability semantics. It interlocks with Edge, which can serve as the validating gateway between role tiers.
Industries served
Where this tier earns its keep.
DRONES
Authentication that survives jamming, mesh disconnects, and 50,000-unit swarm scale.
DEFENCE
Sovereign-grade post-quantum auth for mission-critical operations.
SUBSEA
Authentication over acoustic links, surfacing-window-tolerant.
SATELLITES
Inter-satellite links that authenticate without ground anchor.
Patent posture
Patent pending · Filed 1 May 2026EdSSA Relay is part of the patent application “Decentralised Stateless Structural Authentication” — filed at the Finnish Patent and Registration Office (PRH) on 1 May 2026, a European-jurisdiction filing with PCT international extension planned within the priority year. Fifty-four claims and eleven figures.
