How to mine Pearl

The official repository documents a miner built on vLLM, the AI serving engine, connected to a Pearl full node through a gateway. For now it supports only NVIDIA H100 and H200 GPUs (the sm90 architecture, through CUDA) running AI workloads: the path closest to Pearl’s useful-work idea.

Third-party pools offer separate miners and wider consumer-GPU support. Pearl Research Labs has no pool of its own yet and tells miners to treat third-party pools “with real caution” (its help center (opens in a new tab)). As of October 20, 2026, the largest by reported hashrate were Kryptex and PearlHash, according to MiningBoard (opens in a new tab), a third-party tracker. Their software, fees, payout rules and security are controlled by them, not by Pearl Research Labs or this guide. A mention here is not an endorsement.

Pearl Research Labs also sells compute packages: you pay for a share of GPU work it runs and receive a proportional share of the block rewards, without running hardware. Rewards fall as more compute joins the network and move with the PRL price, so treat any quoted rate as a scenario (how rewards are calculated (opens in a new tab)).

1. 01

   Create a self-custody wallet

   Back up the wallet, then generate a dedicated receive address for mining payouts. See the wallet guide.

2. 02

   Write down your real costs

   Your electricity price, power at the wall, pool fee, downtime and hardware wear all count.

3. 03

   Choose solo or pool

   Solo mining pays rarely but in full; pools pay steadily but add fees and a third party you depend on.

4. 04

   Verify the software

   Use a primary publisher, read the release notes, and check community reports before running any program.

5. 05

   Benchmark for 24 hours

   Measure accepted and rejected shares (the units of work a pool counts), power at the wall, temperature, stability and the actual payout.

6. 06

   Recalculate every week

   Difficulty, price, fees and your share of the network can change faster than your hardware cost.

Estimated daily profit is the PRL you expect to earn times the price you could actually sell at, minus electricity, pool fees, hosting, downtime and a reserve for hardware. If any input is a guess, the answer is a scenario, not a forecast.

• Confirm the pool’s web address from more than one independent source.
• Read its payout method, minimum payout, fee and policy on orphaned blocks.
• Check whether it holds your balance until payout, and what happens if it shuts down.
• Compare regional servers and latency from where you actually are.
• Use a unique worker name, and never reuse an account password.
• Run a small payout test before adding hardware.

Pearl changes its rules at fixed block heights, and miners have to upgrade in time: after the August 2026 salted noise-seed hard fork, old miners produced invalid work. The October 2026 v1.5.0 release told miners and pools to upgrade ahead of everyone else, because it tightened a script validation rule.

The official AI-integrated miner and third-party miners have different requirements. CUDA version, GPU generation, memory, operating system and miner release all matter.

Don’t buy a GPU because of an old video or a calculator preset. Confirm support in the exact miner release you’ll run, then benchmark it at your electricity price.
