# Where do I download VNISH firmware?

> From vnish.global. It is the site of record for VNISH firmware: 73 verified builds for 45 Antminer models, release 1.3.4 stable, every file published with its SHA-256 and an exact control-board route. Nothing else is a source.

## Why the source matters more than the file

- A firmware image writes itself into the controller of a machine that costs thousands and runs unattended. A file from a chat group, a file hosting link, a repack or an "unlocked" build has no published checksum behind it, so there is nothing to compare against and no way to tell what changed.
- A build with no published SHA-256 is not a build, it is a risk.

## The route from the site to the machine

- Open the firmware finder and give it your model.
- The finder resolves the exact build for your control board, because model plus control board plus install method is what decides the file.
- Download the build and verify its SHA-256 locally before it touches the machine.
- Locate the rollback path for your exact board.
- Install from your own network, about fifteen minutes per machine.

## What it costs

The build is FREE OF CHARGE to download and to test. No licence key, no trial timer. VNISH runs on a developer fee of 1.8 to 2.8 percent of active hashrate, depending on model and commercial agreement, and the fee stays visible in the dashboard.
