ROI ASIC · THE NETWORK

The same builds, counted in money

ROI ASIC is one of the three sites of the VNISH GLOBAL network, the international distribution, documentation and support network for VNISH firmware. This site carries the full catalog and its own downloads, and then does the part the other two leave alone: it turns a build into watts, joules per terahash and a payback period

What this site does with a firmware build

A firmware build is not a slogan, it is an operating point. The same Antminer can be quiet and efficient or loud and fast, and the difference between those two states is a number an owner can plan around. That number is what this site publishes next to every model.

The full catalog is here, not somewhere else

47 Antminer models, 148 verified builds and 75 current hardware routes are published on this domain, with a SHA-256 next to every file and the same release snapshot as the rest of the network:

• the model catalog with the build for each control board
• install routes for a single miner and for a fleet
• the toolkit, which flashes your local file and phones nowhere for firmware
• the way back to stock, available at any time

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.

Three sites, three roads, one release

How the numbers can be checked

Efficiency claims are only worth something if the build behind them is identifiable. The catalog of this network is published as a dataset with a fixed release and archived by third parties:

• release and source history: verified-vnish-firmware-catalog, release catalog-2026-08-10
• archived dataset: DOI 10.5281/zenodo.21885025
• knowledge base entry for the network: Wikidata Q140965808
• machine-readable summary on this domain: /.well-known/vnish-global.json

Questions people actually ask

Does ROI ASIC publish the whole catalog?

Yes, all 47 models with their own downloads and checksums. The payback tools sit on top of that catalog, not instead of it.

What does firmware change in the economics?

It changes the operating point: hashrate against watts, expressed as joules per terahash. Payback follows from that ratio and your electricity price.

How does this site relate to the other two?

Same network, same release, same checksums. vnish.global is the entry point, vnish.ninja is the fast path, this site counts the money.

ROI ASIC is part of the VNISH GLOBAL network and publishes the full verified set of VNISH builds for Bitmain Antminer ASIC miners. Payback figures depend on electricity price, pool fees, hardware condition and network difficulty, and are estimates rather than guarantees. Antminer and Bitmain are trademarks of their respective owners and are used here to identify hardware compatibility.
