How to mine Quantus (QTC), step by step.

• Phone. Install the official Quantus Wallet app (iOS, Android), create a wallet, write the recovery phrase down offline, copy the address.
• Terminal. Download a quantus-cli release and run the two commands below. The first prints your address; the second saves the recovery phrase.

./quantus wallet create --name pool
./quantus wallet export --name pool --format mnemonic --output ./seed.txt

• Qelvminer, for NVIDIA cards. Our build: kernels tuned for RTX 30, 40 and 50 series, one file each for Windows, Linux and HiveOS, published with its SHA-256, and a 1 % dev fee you can see on the dashboard. The commands below use it.
• The chain's own quantus-miner. Same protocol, same flags (serve --node-addr … --auth-token … --tls-cert-sha256 …), no extra fee.
• Any stratum miner (SRBMiner-MULTI and others), over TCP on port 4444 or 4443 with TLS. See the stratum line below.

Linux

./qelvminer-1.1.4-linux-x86_64 serve \
  --node-addr quantus.qelvhash.com:9834 \
  --auth-token qzYourQuantusPayoutAddress.rig1 \
  --tls-cert-sha256 d770aeda353aeab5d777f0cda626aa3ecbb4201c5a2801e6661ca232d86e6245 \
  --cuda-gpu \
  --cpu-workers 0

Or from nothing, in one paste: download, verify the sum, make it executable and start.

mkdir -p ~/quantus && cd ~/quantus
wget -O qelvminer-1.1.4-linux-x86_64 https://qelvhash.com/dl/qelvminer-1.1.4-linux-x86_64
echo "aad134e4d0824e22c90771aa3a07d319c4bc44858770726164acb5f971c0d234  qelvminer-1.1.4-linux-x86_64" | sha256sum -c
chmod u+x qelvminer-1.1.4-linux-x86_64

./qelvminer-1.1.4-linux-x86_64 serve \
  --node-addr quantus.qelvhash.com:9834 \

Windows

.\qelvminer-1.1.4-windows-x86_64.exe serve `
  --node-addr quantus.qelvhash.com:9834 `
  --auth-token qzYourQuantusPayoutAddress.rig1 `
  --tls-cert-sha256 d770aeda353aeab5d777f0cda626aa3ecbb4201c5a2801e6661ca232d86e6245 `
  --cuda-gpu `
  --cpu-workers 0

PowerShell, from the download folder. A backtick ends each line instead of the backslash. Windows Defender may ask once: the file carries no code-signing certificate, so check its SHA-256 against the one on the Qelvminer page.

A start.bat to double-click

The usual way to run a rig on Windows: one file next to the miner that starts it from the right folder and starts it again if it ever stops.

@echo off
title Qelvminer
cd /d "%~dp0"
if not exist "qelvminer-1.1.4-windows-x86_64.exe" (
  echo qelvminer-1.1.4-windows-x86_64.exe is not in this folder. Save start.bat next to it.
  pause
  exit /b 1
)
:loop
"qelvminer-1.1.4-windows-x86_64.exe" serve ^
  --node-addr quantus.qelvhash.com:9834 ^
  --auth-token qzYourQuantusPayoutAddress.rig1 ^
  --tls-cert-sha256 d770aeda353aeab5d777f0cda626aa3ecbb4201c5a2801e6661ca232d86e6245 ^
  --cuda-gpu ^
  --cpu-workers 0
echo.
echo The miner stopped (code %errorlevel%). Starting again in 10 s; close this window to stop.
timeout /t 10 /nobreak >nul
goto loop

1. Put the downloaded qelvminer-1.1.4-windows-x86_64.exe in a folder of its own, for example C:\qelvminer. Do not rename it: start.bat looks for that exact name.
2. Open Notepad, paste the text above and replace the placeholder address with yours. The word after the dot is the name of the rig: give each machine its own.
3. In File → Save as, go to that same folder, set "Save as type" to All files and the name to start.bat. Leave the encoding on UTF-8 or ANSI. With the type left on "Text documents" the file becomes start.bat.txt and nothing happens when you open it.
4. Double-click start.bat. A window opens with the miner's header and, within a minute, a status panel that refreshes every few seconds; the rig then appears on the dashboard under your address. Closing the window stops the miner.
5. To mine whenever the PC is on, press Win + R, type shell:startup and put a shortcut to start.bat in the folder that opens.

If the window closes at once or says the file is not in this folder, start.bat and the .exe are in different folders or the .exe was renamed. If only the first line of the command runs, a space slipped in after a ^. The same file, written for you with your address, is in the dashboard generator under "Format".

HiveOS

Add a custom miner with the package qelvminer-hive-1.1.4.tar.gz from the Qelvminer page, then a flight sheet with these values. The rig starts the CUDA engine; NVIDIA only.

{
  "name": "Qelvpool-Hive",
  "isFavorite": false,
  "items": [
    {
      "coin": "",
      "pool_ssl": false,
      "pool_urls": [
        "quantus.qelvhash.com:9834"
      ],
      "dpool_ssl": false,

        "pass": "x",
        "user_config": "--tls-cert-sha256 d770aeda353aeab5d777f0cda626aa3ecbb4201c5a2801e6661ca232d86e6245 --cpu-workers 0 "
      },
      "pool_geo": []
    }
  ]
}

Any stratum miner

Login is qzYourQuantusPayoutAddress.rig1, password x. With SRBMiner-MULTI:

SRBMiner-MULTI --algorithm quantus --pool quantus.qelvhash.com:4444 --wallet qzYourQuantusPayoutAddress.rig1

A share lands within a minute; your rig then appears on the dashboard under your address, with its hashrate, shares and effort. If nothing arrives, the pool speaks QUIC over UDP and some networks block it: what to check. Qelvminer 1.1.4 falls back to the stratum TLS port by itself.
