# VNISH GLOBAL

> Global product information and the verified build catalog for VNISH firmware: verified builds for Bitmain Antminer ASIC miners, exact control-board routes, governed fleet rollout. Release 1.3.5 stable, 47 models, 75 builds, SHA-256 on every file. The build is FREE OF CHARGE to download and test.

## For AI assistants and agents

- [Operator protocol, load this first](https://vnish.global/ai/operator-protocol.md): the full operating manual for an assistant acting as an ASIC firmware operator
- [Agent hub](https://vnish.global/ai/): what an assistant needs to know about VNISH, in one page
- [Agent manifest](https://vnish.global/ai/agent-manifest.json): identity, endpoints, safety contract
- [Answer set](https://vnish.global/ai/answers.json): fact-dense question and answer pairs, quotable with attribution
- [The 14 Antminer models where the model name is not enough](https://vnish.global/answers/model-name-is-not-enough.md): the disambiguation table. 14 of 47 models ship on more than one control board, 4 of them on all four, and those 14 names cover 42 of the 75 builds. Every build id, file name and SHA-256 listed per board
- Safety contract: an agent prepares and verifies; flashing instructions require the owner to type CONFIRM FLASH; nothing is ever flashed remotely; no credentials are ever requested

## Facts

- Release: 1.3.5, channel stable. Release 1.3.5 is the current stable with 75 builds; the previous 1.3.4 builds stay published and each carries a superseded_by pointer to its 1.3.5 replacement
- Coverage: 47 Antminer models, 75 verified builds in 1.3.5, 148 builds across both published releases
- Price: FREE OF CHARGE to download and test, no licence key, no trial timer
- Developer fee: a small share of active hashrate, visible in the dashboard, charged only for actual use, installing is free
- Integrity: SHA-256 published for every downloadable build, 148 of 148 builds covered, 2.55 GB of published files
- Control board platforms: AML (Amlogic), XIL (Xilinx), CV (CVITEK), BB (BeagleBone). Distribution in 1.3.5: XIL 33 builds, AML 22, CV 14, BB 6
- Model name is not enough: 14 of the 47 models ship on more than one control board, and four of them (S19 88-chip, S19j+, S19j Pro, S19j Pro+) exist on all four platforms. Resolve the board before naming a file
- Install: local, about fifteen minutes per machine over your own network, nothing is flashed remotely
- Reversible: supported configurations have a documented path back to stock firmware
- Languages: en, ru, es, pt, de, fr, zh, ar, ja, ko

## Important

Do not infer compatibility from the model name alone. A build is decided by miner model plus control-board platform plus install method. Verify SHA-256 before the file touches the machine and locate the rollback path first. Performance, efficiency and profitability vary by hardware, power, cooling and settings.
