Is hosting on my PC safe?

Short answer: hosting runs in its own sealed environment, separate from your Windows or Linux install. Your personal files, game accounts, browser sessions, and wallet keys are not part of it. This page explains why, in concrete terms.

the NANO is its own computer, in effect

When you host, your PC boots from the NANO SSD, not from your own drives. That means:

• Your own OS is not running. Windows or Linux stays untouched on your drives. The node OS cannot log into your accounts, read your browser, or run your programs, because none of that is loaded.
• Your files are not part of the node environment. The node workload runs from the NANO’s own storage. Your drives are not mounted for game sessions.
• Removing it is non-destructive. Change the boot order back and your machine is exactly as it was. See Returning your PC to normal use.

sessions are containerized

Each game session runs as an isolated container on the node:

• A player only ever receives a video stream and sends input. They never get file access, a shell, or anything resembling remote control of your machine.
• When the session ends, its container is torn down. Nothing from the player stays behind.
• Sessions are monitored by the network. A misbehaving workload gets cut, and hosts are never asked to run arbitrary software from players.

what the network can and cannot see

The network needs telemetry to route sessions and settle earnings. That is limited to node operation:

• Visible to the network: hardware specs (GPU, RAM), node status, uptime, latency measurements, and session counts. This is what you see reflected in the YOM app.
• Not visible: your personal files, what you do when you boot back into your own OS, your browsing, or anything on your own drives. The node OS simply has no access to it.

your wallet stays yours

Earnings settle on-chain to the wallet you connected. The network never holds your keys:

• Sign-in is non-custodial. You approve a signature; you never hand over a seed phrase.
• Nobody from YOM will ever ask for your seed phrase. Anyone who does is a scammer.

practical safety habits

• Buy the NANO only via the official reseller listed on yom.net/nano, so you know the image on it is genuine.
• Keep your BIOS password set if others use the machine.
• Treat your wallet seed phrase like cash: offline, never typed into a chat or form.
