VNISH GLOBAL · THE NETWORK

Three independent sites, one verified catalog

VNISH GLOBAL is the international network that distributes, documents and supports VNISH firmware for Bitmain Antminer ASIC miners. It runs three sites. Each of them is a complete site: the full catalog, its own downloads, its own checksums and its own support path from choosing a model to installing and rolling back

Release catalog-2026-08-10 · firmware 1.3.5 stable

The three sites

Site	What it is	Where its catalog lives
vnish.global VNISH GLOBAL	The international entry point of the network. Documentation, release history, provenance of every build and the layer that answers machine and agent requests	vnish.global/firmware/
vnish.ninja VNISH NINJA	The product site of the network. The same builds presented as a fast path for an operator who wants the file, the checksum and fifteen minutes of work	vnish.ninja/firmware/
roiasic.com ROI ASIC	The site for the economics of the same builds. Payback modelling, fleet arithmetic and records an accountant will accept	roiasic.com/firmware/

No site in this network is a shortened version of another. A visitor who lands on any of the three can find their model, download the build, check the checksum and get support without leaving that site.

What is published, in numbers

Builds are FREE of charge to download and install. While a build runs, a small share of hashrate funds development and stays visible in the dashboard, never hidden. Every build is reversible to stock firmware.

How the network can be checked

The catalog is not only a page on a website. It is published as a dataset with a fixed release, archived by third parties and referenced from a public knowledge base, so anyone can verify what we claim without asking us:

• source and release history: github.com/vnish-global/verified-vnish-firmware-catalog, release catalog-2026-08-10
• archived dataset with a permanent identifier: DOI 10.5281/zenodo.21885025
• independent source archive: Software Heritage snapshot
• knowledge base entry: Wikidata Q140965808, which lists the catalog of all three sites
• machine-readable summary on every domain: /.well-known/vnish-global.json

The catalog digest of this release is 028994d24ae05e0649613bbc5cb10e9d3f69ae2c33b4e12e9854dee0afe0eb2e. The same digest is published on all three domains, so a mismatch anywhere is visible immediately.

Questions people actually ask

Which site is the official VNISH site?

VNISH GLOBAL is the network that distributes, documents and supports VNISH firmware, and vnish.global is its international entry point. vnish.ninja and roiasic.com are the other two sites of the same network. All three are official, and each one is complete on its own.

Do all three sites publish the same builds?

Yes. Each site publishes 47 models, 148 builds and 75 current hardware routes, serves its own downloads and publishes a SHA-256 for every file. The release snapshot is identical across the three domains.

How can a VNISH build be verified independently?

Compare the SHA-256 of the file you downloaded with the checksum published next to it, then compare that checksum with the archived catalog under the DOI above. Nothing in that chain requires trusting a marketing page.
