Everything specific to this pool. For how rewards, rounds and payouts work in general, see how NurseryPool works.
Point your miner here, using your Quantus address as the username:
Quantus addresses start with qz and are 49 characters long. The rig name after the dot is optional.
The official quantus-miner reads --node-addr as a literal IP and refuses a hostname, which is why the address above is an IP. The quanpool miner and SRBMiner both accept quan.nurserypool.com:2255 as well.
Two protocols share that port. quantus-miner and the quanpool build speak native QUIC over UDP; SRBMiner speaks the pool's stratum over TCP. Nothing to choose, each miner uses its own.
Three miners work on this pool. All three handle multi-GPU rigs on their own: one instance, all your cards.
Official miner, no fee. Download and start it:
The GPU is detected automatically. Use --gpu-devices only to limit how many cards are used.
If it stops on UNSUPPORTED_PTX_VERSION, the CUDA runtime is newer than the driver. Prefix the command with an older library path, for instance LD_LIBRARY_PATH=/usr/local/cuda-13.0/targets/x86_64-linux/lib
Quanpool miner, 2% fee announced at startup. Tuned per card at first start:
Measured on the same RTX 5060 Ti: 315 MH/s, so about 299 once the 5% is taken. It is a closed binary from a third party and it phones home for its licence; that is the trade-off for the speed. Its SHA-256 is c1b3a5e5233c9d70bf8e5faaa7671b2738c009cb185a9a341f34b7050f387e35
Fl4shMiner, 1.5% dev fee announced. Source on GitHub, NVIDIA and AMD. The fastest in our own measurements:
Its autotune takes five to eight minutes: it starts low and climbs. Measured here on six RTX 5080 capped at 250 W: 699 MH/s per card, against 676 for the quanpool miner and 506 for SRBMiner, all pool side after stale shares.
SRBMiner-MULTI, 2.5% dev fee. AMD and NVIDIA, no CPU. It speaks the pool's stratum, so a hostname works:
On a fast rig the two options above are needed. SRBMiner starts at difficulty 1,000,000: a multi-GPU rig then submits thousands of shares per second, its watchdog fires, and the session reconnects before vardiff has had time to climb. The miner ends up stuck after a few shares.
To keep it running after you close the terminal, start it inside screen or tmux.
Download the executable, then open PowerShell in the folder that contains it:

SRBMiner-Multi-3-6-7-win64.zip ↗The quanpool miner has no Windows build for now. On a multi-card rig, Linux is the better choice.
Windows may warn about an unsigned executable. The file comes straight from the official Quantus releases page.
HiveOS has no built-in Quantus miner. Use a custom miner: in the flight sheet, pick Custom, then fill in these fields.

Quantus is a proof-of-work chain built on Substrate, with post-quantum signatures. Its algorithm, QPoW, hashes with Poseidon2 over the Goldilocks field.
Share difficulty adapts to each miner so that everyone submits about one share every ten seconds. A share is always credited at the difficulty it was issued at.
PPLNS. When the pool finds a block, it is split between the shares present in the window at that moment, in proportion to the work each represents. The window holds the most recent shares covering twice the network difficulty, which is roughly two hours at the current rate.
Two things follow. A miner who stops before a block is found gets nothing from it, however long they mined before: their shares have left the window. And a miner who has just arrived is already earning, since their shares enter the window straight away.
Mining rewards land in a zero-knowledge tree and become provable at the next block. The pool proves and withdraws them itself, reading its own node rather than any third-party indexer.
Miner will not connect. Check the port is 3355 and that nothing on your side blocks outbound connections. Retype the command rather than pasting it from a web page — invisible characters copied from a browser are a common cause of "no such file or directory" errors.
My address does not appear. Stats take up to a minute to show up after your first accepted share. Check that your address has no typo and that your miner reports accepted shares.
My hashrate looks different from my miner's. The dashboard averages over several minutes; xmrig shows instant and 10-second readings. Compare over a longer window.
