Why a second glossary: The first covers the concepts behind Web4. This one covers the names you will meet while actually using it.
The seven layers, in order:
UIID — Layer 1, identity. A self-owned digital identity held on your own device.
VIVON — Layer 2, connectivity. Global eSIM mobile data with metadata shielding.
ARCTIC — Layer 3, compute. Everyday devices forming a distributed storage and processing network.
HELION — Layer 4, browsing, routing and naming.
TRIVE — Layer 5, software and tools. Free CRM, project management and accounting.
ATRIUM — Layer 6, application delivery. Build your own social network or super app from a single prompt.
WYNIX — Layer 7, hardware. Smartphone, notebook, smart ring and smart glasses.
Tools and components:
GLACIER — the AI studio inside TRIVE. Describe a mini app in plain language and it builds and deploys it.
LNS (Linkspreed Name Service) — Web4's naming service, built around the web4:// protocol. Domains are owned rather than rented, and you can create your own top-level domain.
BRIDGE — the browser built to open web4:// addresses. Ordinary browsers do not resolve them.
W4OS — the custom Android fork developed for WYNIX devices.
Web4 Lite — the open-source starter foundation for running a Web4 network yourself, on GitHub.
Web4 @home — running a Web4 network on very low-cost hardware such as a Raspberry Pi.
UIID Cookbook — practical examples, demos and a Demo Suite for working with the UIID API.
Identity features:
UIID Cloud — an encrypted backup of your identity, enabled by default, so a lost device does not mean a lost identity.
.uiid file — a JSON-structured export of your identity or of a single alias. Treat it like a key, not a document.
Short code — a verified Individual identity shown as seven characters, four emojis or three words. All three point at the same key.
Badge — a verifiable credential sitting on your own identity, so it travels with you across Web4 applications instead of staying inside one app.
Trust score — a numeric signal accompanying a verified identity. Not a social credit score; it reflects identity verification only.
Verifier — an organization authorized to issue credentials to other identities.
Agent Factory — where you issue provisioning tokens for AI agents, instead of sharing a static secret.
Identity types: Human Individual, Organization, AI Agent, Hardware Node, Digital Service, Collective. One identity per real entity.
