Every fourth miner already runs on VNISH
Independent Cambridge study: 26.4% of surveyed mining hashrate, June 2024
⬇DOWNLOAD PDF16 slides · English · 2026 editionA million machines have already run this firmware
Every generation of the Antminer line, from the S9 era to the S21, taught us the efficiency curve, the thermal limit and the board quirks of that exact model
The largest independent firmware in the Cambridge sample
Share of reported hashrate by firmware type, Cambridge Centre for Alternative Finance survey, June 2024. Every fourth surveyed machine on an independent firmware is running ours
The hardware is fixed. What it does with a kilowatt is not
A miner leaves the factory on one universal setting, chosen for every climate and every site at once. Firmware is where that setting stops being universal and starts belonging to your site
Or hold the power envelope and push hashrate. The site decides which answer it needs
Chip-level tuning and thermal policy keep a paid-off fleet inside a profitable window when the market turns
Supported configurations keep a documented path to stock, published before the install
Same machine. Two more profitable answers
+22.7% hashrate for 19.6% more power, and efficiency still improves. Three boards at 77.6, 77.9 and 77.6 TH/s add up to the number above
* Combined effect from using all available options and improvements of the solution. Results vary with hardware, power quality, cooling and settings
No guessed files. No blind flash
Model plus control board plus install method resolve to one published build, with the checksum printed beside it. Two identical looking miners can need two different files
Four control boards cover the whole range · AML, XIL, CV and BB each take a different file
Each step pays for the next
One day under your own load and site conditions. Hashrate, temperature and error rate decide whether step two happens
A named cohort mixed by board and batch carries the change first, with go, hold and stop gates written before the first flash
Never more than a quarter of the floor at once, with a named rollback owner and the stock route reachable for every board type
The machine keeps tuning after the install
Clock and voltage tuned per chip, not per model average
Thresholds, presets and remote updates across the fleet
Board temperature and fan duty stay inside the boundary you set
The route back stays visible, per model and per control board
The install is local, started by you, on your own network. Nothing is flashed remotely and no credentials leave your site
Telemetry is not decoration. It is the evidence for the next decision
One panel per machine and per fleet: hashrate and its history, board temperatures, power draw, pool state, firmware version and the update route
Zero capex. Prove it before you commit
Download the exact build for your machine and test it on your own hardware before anything is agreed
A share of active hashrate, by model and commercial agreement. We are paid while the machine earns, not before
New releases follow new Bitmain hardware, and the engineers behind them stay reachable
Mining Technology of the Year, and shipping since 2017
Blockchain Life 2025 named VNISH Mining Technology of the Year. Behind the award is a firmware line that has followed every Antminer generation since the S9, and a team that answers when a machine goes silent
The pilot earns the next step
Three questions decide whether a cohort becomes a fleet, and all three are answered by your own machines rather than by this deck
TH/s, watts, J/TH and cost per TH measured against your own stock baseline
Rejects, thermals, restarts and uptime across a full day of your site conditions
Install time, monitoring load and how quickly a machine can be returned to stock
Start with one to five miners
Take the exact build for your machine, verify the checksum, run it for a day and let the numbers decide the rest
