Riivab

Riivab is a fictional distributed protocol and software stack designed to coordinate real-time collaboration in immersive digital environments. In the imagined domain, Riivab provides a low-latency messaging layer, a shared scene graph data model, and a plug-in architecture that enables clients to exchange state, assets, and user input across participants. The design emphasizes locality, offline-first operation, and eventual consistency.

Architecture and data model: The core protocol defines message types for scene updates, asset streaming, and access control. State synchronization relies on conflict-free replicated data types (CRDTs) to converge on a consistent world state as participants join or drift apart. The transport layer supports both peer-to-peer communication and rendezvous servers, with optional encryption and authenticated sessions via plugins.

Features and use cases: Riivab is intended for multi-user virtual reality experiences, collaborative design tools, and digital twins where participants interact with shared objects in real time. Its plug-in system allows rendering engines, input devices, and asset pipelines to integrate with Riivab without forcing a single engine or runtime.

History and status: In the fictional ecosystem, Riivab emerged in speculative design fiction in the mid-2020s and circulated through open-source sketches and narrative appendices. There is no real-world standard, governance body, or widely deployed implementation bearing the Riivab name outside this imagined context.
