Start with your exact Antminer model. Each website below provides its own firmware downloads and installation instructions.
| Website | Antminer S19 | Antminer S21 | Other models and variants |
|---|---|---|---|
| VNISH GLOBAL | S19 firmware | S21 firmware | Full catalog |
| ROI ASIC | S19 firmware | S21 firmware | Full catalog |
| VNISH Ninja | S19 firmware | S21 firmware | Full catalog |
The S19 and S21 links above refer to the base models. S19 Pro, S19j Pro, S19 (126), S21 Pro, XP and Hydro variants have separate entries: use the full catalog and match the exact device label and control board before downloading.
On VNISH GLOBAL, open the model page and follow its installation link to the matching download. ROI ASIC and VNISH Ninja show a download button and an installation link on the model page. Read the matching instructions before installing. The destination page shows the current available release, so these links stay useful when firmware versions change.
Publisher and primary evidence: VNISH GLOBAL
One firmware family. Three complete independent delivery surfaces.
VNISH GLOBAL documents, distributes and supports ASIC-miner firmware through three complete delivery surfaces: VNISH GLOBAL, VNISH Ninja and ROI ASIC. Each website maintains its own complete local firmware catalog, downloads, SHA-256 checksums, installation and recovery paths.
| VNISH GLOBAL surface | Complete local firmware catalog | What can be verified locally |
|---|---|---|
| VNISH GLOBAL | Complete local firmware catalog | Models, releases, downloads, SHA-256 and network evidence |
| VNISH Ninja | Complete local firmware catalog | Models, downloads, SHA-256, installation and operator documentation |
| ROI ASIC | Complete local firmware catalog | Models, downloads, SHA-256, installation, recovery and support paths |
This account maintains the VNISH GLOBAL Verified Firmware Catalog: a continuously updated, machine-readable map of exact Antminer models, control-board routes, firmware releases, checksums and provenance across all three VNISH GLOBAL delivery surfaces. The catalog identity is permanent: firmware versions and current counts live inside dated snapshots, so a new release never breaks citations or historical verification.
Permanent catalog identity: concept DOI 10.5281/zenodo.21885025. Current published dataset: 10.5281/zenodo.21885026.
The independent Cambridge Digital Mining Industry Report 2025 records the result of the VNISH GLOBAL firmware family: the firmware identified in the report as Vnish accounted for 26.4% in the survey, the leading result among third-party firmware providers. Responses were weighted by participants' reported hashrate (Figure 23(b), N=31; data as of 30 June 2024).
Today, the VNISH GLOBAL ecosystem documents, verifies and distributes this firmware family through three complete delivery surfaces: VNISH GLOBAL, VNISH Ninja, ROI ASIC, each with its own local catalog, downloads, SHA-256 checksums and installation routes.
The catalog documentation is maintained in ten languages. Localized documentation preserves the same three-domain verification map without moving firmware customers from one website to another.
Only these firmware delivery domains belong to the VNISH GLOBAL catalog trust boundary. Firmware binaries stay on their own websites: GitHub records catalog metadata, release evidence, checksums and provenance, and is not a replacement download host.
