MeowMiner

Pre-tuned miners for NVIDIA GPUs and selected CPU algorithms, distributed as ready-to-run binaries for Windows, Linux, and HiveOS.

Supported coins

Coin	Algorithm	Package	Latest
Keryx (KRX)	keryxhash	`MeowMiner-keryx`	v1.6.25
Pearl (PRL)	pearlhash (int8 tensor-core + BLAKE3)	`MeowMiner-pearl`	v1.6.43
Cereblix (CRB)	neuromorph	`MeowMiner-cereblix`	v1.6.48
BTX (BTX)	matmul	`MeowMiner` multi-coin	v1.6.53
Lucky Pepe (LPEPE)	yescryptR32	`MeowMiner`	v1.3.2
YCash (YEC)	Equihash 192,7	`MeowMiner`	v1.3.2

Keryx ships as its own CUDA package, wrapping Keryx miner 0.3.2 with MeowMiner launchers and HiveOS integration. Pearl ships as its own package (a CUDA engine plus a lightweight pool client). Cereblix ships as a CPU-only package with the optimized NeuroMorph miner, MeowMiner launchers, and HiveOS integration. BTX and Pearl also ship together in the v1.6.53 multi-coin package, selected with --coin btx or --coin pearl and supporting disjoint GPU assignment. Lucky Pepe and YCash share a single unified launcher, selected with --algo.

BTX + Pearl multi-coin

MeowMiner v1.6.53 combines the native BTX matmul miner and Pearl pearlhash miner behind one launcher. BTX validates the exact candidate header against the consensus pre-hash gate before submission; Pearl retains its architecture-specific Ampere, Ada, Hopper, and Blackwell engines.

BTX: LuckyPool by default, with NinjaRaider also supported; no dev fee.
Windows RTX 5070: automatic 12 GB compatibility profile.
Pearl: HeroMiners by default, 2% dev fee.
GPU assignment: use --devices 0,1. Separate instances can mine BTX and Pearl concurrently when their device lists do not overlap.

Installation URL	`https://github.com/JustAResearcher/MeowMiner/releases/download/v1.6.53/meowminer-1.6.53.tar.gz`
Miner name	`meowminer`
Hash algorithm	`btx` or `pearl`
Wallet and worker template	the matching `btx1z...` or `prl1...` address
Pool URL	`btx-us-east.lproute.com:8660` or `us2.pearl.herominers.com:1200`
Pass	`x`

Set MEOW_COIN=btx or MEOW_COIN=pearl in Extra config if the flight-sheet algorithm field is unavailable. Use CUSTOM_DEVICES=0,1 to restrict GPUs.

Keryx (KRX)

A CUDA miner package for Keryx keryxhash, with optimized Ada / sm_89 and Blackwell / sm_120 kernel paths for RTX 40-series and 50-series GPUs.

Architectures: NVIDIA CUDA GPUs; RTX 4070 Ti SUPER uses the optimized sm_89 cubin, and RTX 5090 / 50-series uses the optimized sm_120 cubin.
Components: MeowMiner-keryx and the keryxcuda plugin.
Pool default: LuckyPool stratum+tcp://keryx-us.lproute.com:8460.
Model tier: package starter scripts use --light to minimize OPoI model requirements.

Pearl (PRL)

A tensor-core miner for Pearl's pearlhash proof-of-work — an int8 matrix-multiply workload finalized with BLAKE3. NVIDIA-only.

Architectures: Ampere, Ada, Hopper, Blackwell (sm_86 / sm_89 / sm_90 / sm_120).
Optimized GPU paths: RTX 30-series / sm_86, RTX 40-series / sm_89, and RTX 50-series / sm_120 are supported and route to tuned Pearl kernels.
Components: a CUDA engine (MeowMiner-pearl) and a pool client (pearl_ours). The Linux client is statically linked and runs on any modern distribution and on HiveOS (engine built against glibc 2.17).
Requirements: a recent NVIDIA driver. The CUDA runtime is linked statically into the engine, so there is nothing else to install.
Multi-GPU: the launcher detects every GPU and runs one instance per card.
Fee: 2%, applied as a brief time slice; the GPU never pauses.

Downloads

OS	Download
Windows 10/11 x64	MeowMiner-pearl-1.6.43-windows-x64.zip
Linux x86_64	MeowMiner-pearl-1.6.43-linux-x86_64.tar.gz
HiveOS	meowminer-pearl-1.6.43.tar.gz
MMPOS	meowminer-pearl-1.6.23-mmpos.tar.gz

v1.6.43 is the full parity Pearl package for Windows, Linux, and HiveOS. Each package includes the RTX 30-series sm86 engine, the RTX 40-series Ada engine, and the Blackwell/Hopper legacy engine. The launchers select by GPU compute capability per card: 8.6 uses MeowMiner-pearl.sm86, 8.9 uses MeowMiner-pearl, and 9.0 / 12.0 use MeowMiner-pearl.legacy.

The sm86 path uses the fixed-grid/no-forced-L2-block default measured faster on RTX 30-series. The launcher prints the selected engine and sm86 scheduler flags per GPU; an RTX 3060 Ti default run should show sm86_fixed_grid=38, l2block=n/axn/a, and bk64_stage=2. This is a software-only kernel/scheduler package update; it does not change clocks, fan settings, or power limits.

Windows and Linux

A wallet and pool are both required; the miner will not start without them and never falls back to a default. Open start.bat (Windows) or start.sh (Linux), set your Pearl wallet (prl1…) and pool, then run it — the script detects every GPU and launches one instance per card.

To run the client directly, or to target specific GPUs:

./pearl_ours --wallet prl1youraddress... --pool us2.pearl.herominers.com:1200 --worker rig1
./pearl_ours --dev 1 --wallet prl1youraddress... --pool us2.pearl.herominers.com:1200   # GPU 1 only

Flag	Purpose
`--wallet <prl1…>`	Pearl payout address (required)
`--pool <host:port>`	Stratum pool (required)
`--worker <name>`	Worker / rig name
`--dev <index>`	GPU index — run one instance per card to mine a subset

HiveOS

Create a Custom miner flight sheet with the following fields:

Field	Value
Installation URL	`https://github.com/JustAResearcher/MeowMiner/releases/download/v1.6.43/meowminer-pearl-1.6.43.tar.gz`
Miner name	`meowminer-pearl`
Hash algorithm	`pearlhash`
Wallet and worker template	`%WAL%.%WORKER_NAME%`
Pool URL	`us2.pearl.herominers.com:1200`
Pass	`x`

Allow roughly 60 seconds after applying for the GPU engine to initialize. A separate sm86-only HiveOS package is no longer needed for RTX 30-series cards.

MMPOS

Register a Custom miner with the package URL, then set the pool, wallet, and arguments in the flight sheet:

Field	Value
Custom miner URL	`https://github.com/JustAResearcher/MeowMiner/releases/download/v1.6.23/meowminer-pearl-1.6.23-mmpos.tar.gz`
Pool	`us2.pearl.herominers.com:1200`
Wallet	your `prl1…` address
Arguments	`--wallet %wallet_address% --pool %pool_server%:%pool_port% --worker %rig_name%`

The agent launches one instance per GPU and reports per-GPU hashrate to the dashboard.

Reference performance

GPU	pearlhash
RTX 5090 (v1.6.19)	~325 TH/s
RTX 4070 Ti SUPER (v1.6.20 Ada path)	~181.6 TH/s

Pool-credited rate depends on the pool's difficulty target and PPLNS window.

Sample output

pearl-ours: 175.2 TH/s | acc=12 rej=0 ping=48ms

Cereblix (CRB)

An optimized CPU miner package for Cereblix neuromorph. This is the MeowMiner-wrapped NeuroMorph miner used on the Mini rigs and AI hosts.

Architectures: x86_64 CPUs with AES-NI and AVX2; VAES and AVX-512 are selected automatically when available.
Components: MeowMiner-cereblix, the optimized nmminer-cereblix binary, and bundled source/rebuild scripts.
Pool default: us.cereblix.com:3333.
Dev fee: 2.00% to crb1c41078c7d958b88042c22f0c3c4cbedc9e8d9dba at us.cereblix.com:3333.
GPU: not used by this package; run Pearl/Keryx GPU mining separately if desired.

Downloads

OS	Download
Windows 10/11 x64	MeowMiner-cereblix-1.6.48-windows-x64.zip
Linux x86_64	MeowMiner-cereblix-1.6.48-linux-x86_64.tar.gz
HiveOS	meowminer-cereblix-1.6.48.tar.gz

Windows

Extract the zip, then edit start.bat and set your Cereblix wallet, or run:

start.bat crb1youraddress rig1

The Windows release is built with a portable AES-NI baseline; AVX2, VAES, and AVX512 paths are selected at runtime only when the CPU supports them.

To override Cereblix thread autotune, pass a thread count as the third argument:

start.bat crb1youraddress rig1 28

Direct run example:

MeowMiner-cereblix.exe -o us.cereblix.com:3333 -u crb1youraddress.rig1 -p x -lanes 1 -noupdate
MeowMiner-cereblix.exe -o us.cereblix.com:3333 -u crb1youraddress.rig1 --cpu-threads=28 -noupdate

Linux

Edit start.sh, set your Cereblix wallet, then run the script. Worker names are appended by default, for example crb1...rig1.

WALLET=crb1youraddress WORKER=rig1 POOL=us.cereblix.com:3333 ./start.sh
WALLET=crb1youraddress THREADS=28 ./start.sh

Direct run example:

./MeowMiner-cereblix -a neuromorph -o us.cereblix.com:3333 -u crb1youraddress.rig1 -p x -noupdate
./MeowMiner-cereblix -a neuromorph -o us.cereblix.com:3333 -u crb1youraddress.rig1 --cpu-threads=28 -noupdate

HiveOS

Create a Custom miner flight sheet with:

Field	Value
Installation URL	`https://github.com/JustAResearcher/MeowMiner/releases/download/v1.6.48/meowminer-cereblix-1.6.48.tar.gz`
Miner name	`meowminer-cereblix`
Hash algorithm	`neuromorph`
Wallet and worker template	`%WAL%.%WORKER_NAME%`
Pool URL	`us.cereblix.com:3333`
Pass	`x`

To override Cereblix thread autotune in HiveOS, set Extra config arguments to --cpu-threads=28 or -threads 28 -noauto. The package also accepts threads=28, CUSTOM_THREADS=28, and CUSTOM_CPU_THREADS=28.

The package reports CPU hashrate in kH/s and keeps the GPU miner untouched.
