Private and federated observing grids for networks…" url: https://observatory.global/grid-services/technologies/ publisher: Nexus Observatory Inc. updated: 2026-11-02 --- [Nexus Observatory](https://observatory.global/) / [Protocol & Grid](https://observatory.global/grid-services/) / **Technologies** # The technologies behind protocol & Grid. Every technology this platform builds with, layer by layer, from the open taxonomy. Marked in red: what is moving now, each traced to its source. [Plan with us](https://observatory.global/grid-services/contact/deployment/) [Architecture](https://observatory.global/grid-services/architecture/) Areas · **5** Technologies · **61** Industries · **6** **01** The layered map ## Layer by layer, from the open taxonomy. Each domain this platform draws on, with its layers and the technologies in each. Open a layer for what each technology does and the standard behind it. ### Security, identity and trust How every node proves what it is and what it runs, how links and keys are protected, how software is traced to its source, how personal data is minimised, and how incidents are found and handled.
