Open-source PearlHash (PRL) miner for NVIDIA Blackwell GPUs - 0% dev fee

Download, build instructions and quickstart:
https://github.com/pushsoftnow/blackwell_pearl_miner

Hi all,

we just released bpm, a free and open-source PearlHash miner for NVIDIA Blackwell (sm_120) GPUs.

Features
  • Performance on par with current Blackwell miners - RTX PRO 4500 Blackwell at a 150 W power limit: ~170 TH/s pool-verified on Kryptex (10 h run, 702 shares accepted, 0 reject
    ed). In our own side-by-side test the top closed-source miner delivered 169.8 TH/s pool-verified on the same card and settings.
  • No dev fee - none at all. 100% of your hashrate goes to your own pool and wallet. There is no hidden second pool connection. The code is there for you to check.
  • Background mode - the miner pauses within ~0.4 s as soon as any other process computes on the GPU (games, LLM inference servers, rendering) and resumes 10 s after the GPU is
     idle again. Processes that only keep VRAM allocated (e.g. an idle LLM server) do not pause it. The miner itself needs only ~430 MiB VRAM.
  • Open source (ISC license) - Rust host and CUDA kernels, fully auditable. Every share is checked with the official Pearl verifier before it is submitted.

Tested so far only on an RTX PRO 4500 Blackwell. Results from other sm_120 cards (RTX 50 series, RTX PRO 6000) are very welcome. Feedback, issues and PRs are appreciated!

Update: faster kernel + first RTX PRO 6000 results

RTX PRO 6000 Blackwell Max-Q, 250 W (user report, 30 min each)
  • bpm: 360.10 TH/s
  • SRBMiner 3.8.6: 310.55 TH/s
  • bpm is +16 % faster

Kernel update (RTX PRO 4500, 150 W)
  • The kernel reorders its operand columns to avoid shared-memory bank conflicts.
  • The compute rate rose by 0.9 %, from 167.4 to 169.0 TMAC/s.
  • The results are bit-identical, with 4450 shares and 0 invalid on a verifying pool.
  • To update, just pull and rebuild.

Thanks to the RTX PRO 6000 tester!

Still looking for results from:
  • RTX 5090
  • RTX 5080
  • RTX 5070 Ti
  • RTX 5070
  • RTX 5060 Ti / 5060
  • RTX 5050
