Antminer firmware by Happy Mining

the Hole

A clean, signed firmware for Antminer S19k Pro and T21 — no vendor backdoor, a modern dashboard, a full API, and fleet-wide installs and updates from MoleHash.

What you get

The miner side of MoleHash: the firmware your fleet runs, managed from the same dashboard.

Signed end to end

Every package is signed (RSA-4096 / SHA-256) with a key the miner trusts. A tampered image is refused before it touches the flash.

Your keys, your miners

No vendor backdoor key, no remote-update agent calling home. SSH is root-only and key-based: you add your own keys from the dashboard.

Clean dashboard + full API

Hashrate, boards, pools, throttle, logs, notes, locks and API keys on one page — and every action available as an HTTP API for automation.

Fleet-managed from MoleHash

Install, update and configure thousands of miners from the MoleHash dashboard through the site agent — no laptop in the container.

Safe updates

Updates are verified on the miner and switched atomically; the previous image stays bootable until the new one is in place.

Antminer S19k Pro & T21

Amlogic and Xilinx control boards today (aml / xil). More models follow the same package format.

Install from MoleHash

Three steps, from the dashboard, for one miner or a whole building.

1
Add the package to your library

MoleHash → Miners → Firmware → Upload package. The platform stores the signed .tar.gz and its SHA-256.

2
Pick the miners

Filter by rack, model or current firmware. Miners coming from another firmware take a first install over SSH; miners already on the Hole use their own signed updater.

3
Install

The site agent downloads the package, hands it to each miner, follows the result. Miners reboot on the new firmware in 2–3 minutes.

Stock Bitmain miners only accept Bitmain-signed images and have no SSH. Put the Hole on them once with the vendor tool or the SD-card method; from then on every update comes from MoleHash.

Easy install

For a technician with a laptop on the miner's network. MoleHash gives you a 7-day install link per package.

terminal
curl -fsSL '<install link from MoleHash>' | sh -s -- <miner-ip> [password]

Downloads the signed package, checks its SHA-256, refuses a package built for another control board, copies it over SSH, runs the installer and reboots the miner. Works on any miner with SSH enabled, and on the Hole.
