VNISH GLOBAL · POWERING VNISH WORLDWIDE

Every fourth miner runs on VNISH

26.4% of the hashrate reported by 31 mining firms used VNISH - the largest third-party firmware share in the Cambridge survey.

VERIFIED BUILD FINDER

Match the machine before you download

Compatibility is not just a model name. The route is defined by model, control board and installation method.

Match the machine before you download
Read the exact Antminer model from the device label or current interface.
Select the board platform. A wrong board selection can make the file incompatible.
3 · Verified installation route...The current 1.3.4 catalog contains 73 verified NAND routes. No Web, Toolkit or SD alternative is inferred.

THE PRODUCT, NOT THE PROMISE

The operating decisions are visible

VNISH brings performance, power, temperature, cooling and board state into one practical control surface. Each value supports a decision, a limit or a diagnostic step.

Official VNISH demo interface · Antminer S21 · Xilinx · example data · no performance promise
01Hashrate target · Compare the requested and observed operating point
02Power · Track watts and measured efficiency
03Thermal state · Read temperatures and fan response before raising limits
04Board visibility · Isolate board-level instability and errors
05Operating profile · Apply a defined profile, then observe the result
FOUR OUTCOMES

Four decisions. Four proof artifacts

01

Confidence before installation

Use a compatibility matrix built around model, board and method.

Artifact · exact catalog match
Signal · one unique build

02

Controlled deployment

Start with a defined cohort, success thresholds and an explicit rollback gate.

Artifact · pilot protocol
Signal · go / hold / rollback

03

Measured economics and risk

Judge TH/s, watts, W/TH, temperature and stability together.

Artifact · operating envelope

04

The right level of access

Self-service, technical support, fleet planning and partnership follow different routes.

CONTROL LOOP

Choose the constraint you need to manage

Firmware settings do not remove physical limits. They make the operating point visible and adjustable within the capabilities of the silicon, PSU, power input and cooling system.

Stable operating envelope
  1. 01

    Performance · Raise the target only while power, temperature and stability remain inside defined limits.

  2. 02

    Efficiency · Find a lower W/TH operating point without assuming the same result across every unit.

  3. 03

    Thermal and acoustic control · Coordinate temperature targets and fan behaviour for the actual site.

  4. 04

    Stability under constraints · Use measured profiles when power, cooling, density or component condition is limiting.

GOVERNED ROLLOUT

Do not scale an assumption. Scale an observed result

A fleet rollout is a controlled change process. Define the baseline, isolate a pilot group, agree thresholds, observe and keep rollback available.

BASELINE → PILOT → THRESHOLDS → OBSERVATION → DECISION

Build a fleet pilot brief
  1. 01

    Baseline

    Current build, power, temperature, hashrate, errors and site constraints.

  2. 02

    Pilot cohort

    A limited representative group with recorded hardware context.

  3. 03

    Thresholds

    Go/no-go limits for stability, temperature, power and errors.

  4. 04

    Observation

    A defined period and comparable telemetry.

  5. 05

    Scale or rollback

    Evidence-backed expansion or a controlled return.

STABLE 1.3.4

The file is only the beginning of the route

Check compatibility, method, filename and SHA-256 together. Read verified notes and limitations before installation, and keep recovery status visible.

45 model families · 73 exact build routes · 73/73 SHA-256 published

45 model families, 73 exact NAND routes and a published SHA-256 for every build. Confirm the board-specific recovery route before installation

VERIFY BEFORE INSTALL

A match means the bytes equal the published build

A mismatch means do not install. SHA-256 does not independently prove authorship, safety or compatibility.

Verify SHA-256
ONE SYSTEM · TEN LANGUAGES

Global reach needs precise local routes

Firmware, installation guidance, verification and fleet entry points are available across ten language routes. VNISH Global on LinkedIn connects product updates with operators, hosts and industry partners.

Questions before the change

How do I know which build fits my miner?

Match the exact model, control-board platform and supported installation method. Do not use a file from a similar model.

Why should I verify SHA-256?

It confirms that the downloaded bytes match the published build. A mismatch means stop and download again from the verified route.

How should a fleet rollout begin?

Record a baseline, select a limited representative cohort, define go/no-go thresholds and keep rollback available before expansion.

Does custom firmware guarantee a result or preserve warranty?

No. Results vary by unit and environment, and warranty treatment is determined by relevant manufacturer or service terms.

One machine or one thousand. Start with the exact route

Match the hardware and verify the build - or define a controlled pilot before changing a fleet.
