Allhs

Allhs is a term used primarily in speculative fiction and online world-building communities to describe a hypothetical universal framework for interoperable information exchange, governance, and infrastructure coordination. It is not an established real-world technology or policy.

The term is sometimes presented as an acronym, with proposed expansions such as All-Habitats Synchronization System or All-Humanity Signal, but there is no canonical form. In many works, Allhs is used as a proper noun, leaving its meaning intentionally flexible to fit the story or design.

In these contexts, Allhs envisions modular, open-standard architectures capable of scaling from a single city to a planetary or orbital network. Core concepts often include interoperable data schemas, consent-respecting data sharing, decentralized governance, and resilience across diverse jurisdictions and environments.

In fiction and media, Allhs appears in projects such as the novella Allhs Horizon and the indie video game Allhs City, where it functions as the umbrella framework that harmonizes transportation, energy, communication, and civic services.

Outside fiction, Allhs is used as a design prompt or thought experiment in discussions about future urbanism, digital governance, and cross-domain interoperability, illustrating how diverse systems might coordinate under a common standard.
