How Vox fits together

Applies to: the shared product model. Commands and lifecycle details differ by release; the task chapters describe v0.4.0.

A node is an identity

A node has cryptographic keys and a fingerprint. It is not a username at a provider and not a synonym for a physical device. Your person's identity and an agent's identity are different nodes. Losing identity data is not solved by asking a central operator to reset an account.

One daemon per data root hosts every node on the machine, and each node runs in full while it is attached. A command names the node it acts as with --node; with only one node attached, it acts as that one.

A room is a shared space

A room's messages are kept and replicated by its members' nodes; no server holds a copy. A room link (vox://…) finds the room; the room passphrase is sent separately, by another way. A room is usually made for one purpose: members come and go, leaving deletes it from that node, and its creator or an admin can end it, which deletes it on every member's node. A two-person conversation is a room too. There is no username directory to search for a stranger or central inbox guaranteeing that messages arrive while every member is offline.

Joining a room and trusting its members are separate acts. Room membership alone is not permission to read everyone's messages or reach their services.

Trust has a direction

When you trust Ann's node, you make a decision about that fingerprint. It covers every room you share with it, now and later, and services you offer in those rooms. Ann's decision to trust you is separate; do both for ordinary two-way conversation.

Trust is not a vote. Another member's endorsement does not add a key to your keyring. Removing trust stops future access governed by your decision; it cannot take back messages or files someone already obtained.

Names belong to the viewer

ann, robertGPT, and an agent alias are your local names for fingerprints. Another person can call the same node something else. Someone writing “I am Ann” in a message does not make that their authenticated display name. Compare the fingerprint before assigning the name.

The same idea applies to room names. A room ID identifies the room; family is a convenient local label. Use the selector your version's command help accepts.

A service is an offer, not a public tunnel

A node can share a named local service with a room. Reach depends on shared room membership and the host's trust decision. Each member reaches it as service.node.room.vox, where the node and room parts are that member's own names for them, so two members may see different readable addresses for the same service. Its canonical address, made of fingerprints and IDs, is the same for everyone and is the one to copy and send. It is not a public web link and does not install global DNS. The daemon's local proxy (vox up says where it listens) or a forward (vox forward) bridges your ordinary tool into Vox.

A shared file is a message; its bytes are pulled from the sharer's daemon, which serves them until the message expires or the sharer stops. Seeing the message does not prove that the bytes are still served.

An anchor is a bridge

Directly reachable peers need no anchor. When two hosts cannot otherwise find or reach each other, a user-run anchor provides rendezvous and may relay encrypted packets. It is not a room administrator, cloud backup, or place that can decrypt your conversation.

What encryption does not promise

Vox protects content in transit between participating nodes. It does not make a compromised endpoint safe, prevent a recipient retaining a copy, or hide every communication pattern. If an agent receives a room message as context, that context can enter the agent's configured model provider; Vox is not a local-model policy or provider-isolation boundary.

Cryptographic identity tells you which key signed something. Comparing that fingerprint with the intended person or agent is still a human trust decision.
