# Mouillay Quantus CPU Miner · 0.1.0-beta.1

Windows x64 public beta for **Quantus (QTC)**. CPU-only, with exact QPoW Poseidon2 / Goldilocks hashing. General x64 build with runtime AVX2 detection and a scalar fallback. **Developer fee: 1% of active scan time on poolmouillay.com (any port), 2% on other pools.** This is separate from the PEARL CPU miner and the browser miners.

## Download and start

Download the Windows ZIP and extract it to a writable folder. It contains exactly:

- `MouillayQuantusCPU.exe`
- `START_MINER.bat`

Edit the BAT before mining:

```bat
set "POOL=poolmouillay.com:3371"
set "WALLET=YOUR_PUBLIC_QUANTUS_ADDRESS"
set "WORKER=worker"
set "CPU_THREADS=0"
```

The shipped wallet is the owner's public test address. **Replace it with your own Quantus address to receive rewards.** Never enter a private key or seed phrase. The default pool is Poolmouillay's CPU-friendly Quantus TCP port 3371. Other pools must implement the compatible login/job/submit TCP protocol. TLS and the official node QUIC protocol are not supported by this beta.

`CPU_THREADS=0` detects physical cores and offers that number at startup. A positive value uses exactly that many workers without a prompt (1–256). This native miner uses physical-core detection; the web miners use browser-reported logical processors. More threads do not always improve throughput.

Double-click the BAT to start. **Ctrl+C stops mining.** Set `MODE=benchmark` in the BAT for a ten-second offline test. The executable also supports:

```powershell
.\MouillayQuantusCPU.exe --version
.\MouillayQuantusCPU.exe --self-test
.\MouillayQuantusCPU.exe --benchmark --threads 12 --seconds 10 --json
.\MouillayQuantusCPU.exe --mine --pool poolmouillay.com:3371 --wallet YOUR_PUBLIC_QUANTUS_ADDRESS --worker worker --threads 12 --seconds 0
.\MouillayQuantusCPU.exe --notice
```

`--password "d=100000"` requests custom share difficulty on compatible pools. Pool settings and targets remain authoritative. `--seconds N` bounds a test run; `--seconds 0` runs until stopped. `--stop-after-share` stops after the first explicit acceptance. The test starts only when you run the application; nothing is installed for automatic startup.

No GPU, CUDA Toolkit, Python, administrator rights, clock changes or security-setting changes are required. Twelve physical-core affinity assignments are attempted for a twelve-worker test when the topology permits it; failed affinity falls back to the Windows scheduler. Older CPUs and other machines have not been exhaustively tested.

## Validation · 10 November 2026

The selected C9 kernel remains `avx2x4-c9-deferred-immediate`. This update adds account-separated developer-fee scheduling and fresh nonce prefixes on resume. Its engine and arithmetic source hashes match the preserved winning prototype.

- Ten-second offline benchmark with **12 workers: 7.295 MH/s** on the development machine. Local nonce evaluations, not a guaranteed or pool-credited rate. Do not compare directly with GH/s MAC-equivalent PEARL measurements.
- 16 application tests passed. Self-test: 5 upstream vectors, 264 independent full-reference comparisons, 15 strict target boundaries and nonce carry cases passed.
- Owned local fixture: 3 independently verified submissions and 2 matching acknowledgements, with fragmented pool messages and job rotation.
- **Real Poolmouillay test, port 3371:** one actual job received, one share explicitly accepted, zero rejections. Four candidates were sent; the test stopped immediately after the first acceptance, leaving three acknowledgement states unknown. The very short run is not a sustained hashrate benchmark or a claim that a block or reward was earned.

## Beta limitations

This is an experimental command-line beta, not a finished graphical application. It supports the tested TCP pool dialect and remains separate from the official node QUIC miner. Network interruptions, pool compatibility, cooling and competing applications affect results. No profitability or reward guarantee is made. No PEARL/NOCK merge mining is included: Quantus is a separate chain.

## Developer fee

Developer fee: 1% of active scan time on poolmouillay.com (any port), 2% on other pools. The exact hostname is compared case-insensitively, with an optional trailing dot; subdomains and IP addresses use 2%. Mining starts on your wallet. Approximately 297 seconds of user scanning at 1%, or 147 seconds at 2%, are followed by about 3 seconds of developer scanning. Polling overshoot is carried into the next interval. Connection and job waits are excluded; offline benchmarks have no fee. Two persistent accounts use the selected pool and password. Your worker is preserved; only the developer account uses `devfeecpu`.

Developer beneficiary: `qznRtYqTb5DUwCNgg7CzyDpAryM16wMGSdQxXDfMEwBeA1bHS`. Fees allocate computing time, rather than deducting a percentage of accepted shares. The same beta version and download URL have been replaced; download again to receive this update.
