How to mine Quantus (QTC) on your GPU
Updated 13 November 2026 · Pasiv 0.7.7 · Settings → Labs · NVIDIA on Windows & Linux · Apple Silicon Macs · experimental
Quantus (QTC) is a young layer-1 blockchain built around post-quantum signatures, and new coins come from proof-of-work — work a graphics card can do. From Pasiv 0.7.7 there is a Labs switch that puts your graphics card on Quantus instead of Pearl. It is opt-in and experimental: off unless you turn it on, and it may change or be removed. Turn it off and the card goes back to Pearl, or to idle where Pearl isn't offered.
It is also the first GPU lane a Mac has: on an Apple Silicon Mac the switch puts the Mac's own GPU to work through Metal, while the CPU keeps mining Monero. On Windows and Linux it runs on NVIDIA cards.
Like everything else in Pasiv, you are paid in USDT or BTC to your own address by the pool, unMineable — Pasiv never holds your money. Pasiv's fee on Quantus is 4% of mining time, the same as on every other coin, taken only while you are mining.
Three steps
- Install Pasiv from the install page (free; macOS, Windows and Linux) and set it up as usual.
- Have a USDT or BTC payout address. Quantus is paid only to a USDT or BTC address, the same one the rest of Pasiv pays — there is no native QTC payout. If you haven't added one, the switch says so and points you to Wallets first.
- Turn on Settings → Labs → Mine Quantus on the GPU. That's it, mining or not: Pasiv stops, saves and starts again with your graphics card on Quantus. The first time, it downloads its Quantus engine. Turn the switch off any time to go back.
The switch only appears on a machine that can run it: any Apple Silicon Mac, or a PC with an NVIDIA card Pasiv can mine on.
The facts
| Status | Labs: opt-in, experimental. Off by default; it may change or be removed. Pearl stays the default GPU coin |
| Hardware | NVIDIA, Turing generation or newer (GTX 16 / RTX 20-series and up), on Windows or Linux, through CUDA — no CUDA toolkit to install. Apple Silicon Macs through Metal. AMD Radeon is not offered |
| Engine | Pasiv's Quantus engine: Pasiv's own build of the official open-source Quantus miner (Apache-2.0), with Pasiv's pool client. Fetched from pasiv.network the first time you start with the switch on, checked against a pinned SHA-256 fingerprint before every start, and code-signed by Pasiv on Windows |
| Pool | unMineable, which converts what you mine and pays your own address |
| Payout | USDT or BTC to your own address. Pasiv is non-custodial and never touches your funds |
| Cost | Pasiv is free; its 4% time-sliced fee applies to Quantus exactly as to other coins: about 10 minutes in every 4 h 10 min of mining, only while mining (fees) |
| Measured | RTX 4070 SUPER ≈ 390 MH/s (Windows, CUDA); M4 Max ≈ 62–72 MH/s (Metal); 285 accepted / 7 rejected shares over about five hours |
Frequently asked questions
What is Quantus?
Quantus Network is a layer-1 blockchain designed around post-quantum cryptography: its signatures use a scheme meant to stay secure against future quantum computers. Its coin, QTC, is issued through proof-of-work, which is what a graphics card can contribute. It is a young network; treat it as such. More at quantus.com.
How do I turn Quantus mining on?
In Pasiv 0.7.7 or later, open Settings → Labs and turn on Mine Quantus on the GPU (experimental). It needs a USDT or BTC payout address saved in Wallets. Pasiv restarts mining with the graphics card on Quantus; the CPU keeps mining as before.
How am I paid for Quantus?
The pool, unMineable, pays your own USDT or BTC address — the same address the rest of Pasiv pays. There is no native QTC payout. Pasiv has no wallet and no balance, and never asks for a key or a seed phrase.
What does it cost?
Pasiv is free. Its fee is 4% of mining time, on Quantus exactly as on every other coin: the graphics card mines to Pasiv's published fee address for about 10 minutes in every 4 h 10 min, only while mining, and every slice is in the app's fee ledger. Separately, unMineable's pool fee is 0.75% (1%, lowered by Pasiv's referral code); unMineable pays Pasiv a 0.25% referral out of its own fee, not out of your earnings. The Quantus engine takes no developer fee.
Which graphics cards can mine Quantus?
On Windows and Linux, NVIDIA cards of the Turing generation or newer (GTX 16 / RTX 20-series and up), through CUDA — you don't need the CUDA toolkit. On a Mac, any Apple Silicon Mac, on its built-in GPU through Metal. We measured about 390 MH/s on an RTX 4070 SUPER and 62–72 MH/s on an M4 Max. The Labs switch only appears where it can run.
How much does Quantus mining earn?
We don't publish a figure yet: we don't have a source for it we'd stand behind. Earnings follow the live network and the QTC price, which is young and moves. Once your machine is mining, the figure Pasiv shows for it is the one to trust.
Is it safe? Is the miner signed?
The engine is Pasiv's own build of the official open-source Quantus miner (Apache-2.0). Pasiv downloads it from pasiv.network only when you turn Quantus on and start, checks it against a pinned fingerprint before every start, and signs the Windows build — on our Windows test machine the signed build ran with no Microsoft Defender detections. Nothing is downloaded on a machine that never turns the switch on.
Can I go back to Pearl?
Yes, any time: turn the Labs switch off. On a PC with an NVIDIA card the graphics card goes straight back to Pearl; on a Mac, where Pearl isn't offered, the GPU goes back to idle and the CPU carries on mining Monero.
