How to Mine Pearl (PRL): GPU Mining Guide (2026)

Pearl is the rare new coin with a genuinely new idea: its pearlhash algorithm is real int8 matrix multiplication — the same math AI inference runs — so every share your GPU submits is verifiable matrix compute, not a throwaway puzzle.

We build the HydraX miner, and as of v3.0.1 it mines Pearl on a cleanroom pearlhash kernel at a flat 1% dev fee (more below). This is the hands-on guide: which cards mine PRL, the miners and pools you can use today with their real fees, the launch steps, and how to tune a compute-bound algorithm — the opposite of everything you learned on Etchash.

What is pearlhash, and why "useful work" matters

Most proof-of-work burns electricity on math that exists only to be hard. Pearl doesn't: pearlhash is built on int8 matrix multiplication, the core operation of AI inference — so when your GPU mines PRL, each accepted share is a verifiable proof of real matrix work.

Two practical consequences follow. First, pearlhash maps onto the tensor-math strengths of modern NVIDIA cards, which is why NVIDIA GPUs are the only realistic option today — RTX 30, 40 and 50 series all mine it. Second, the algorithm is compute-bound, not memory-bound: core clock drives hashrate and memory clock barely matters, which flips the usual GPU-tuning playbook on its head.

What you need before you start

1. An NVIDIA RTX 30, 40 or 50 series GPU. Hashrate scales with compute, so big silicon wins: an RTX 5090 does ~320 TH/s, an RTX 4090 ~230 TH/s, an RTX 5080 ~183 TH/s, and an RTX 5070 Ti ~137 TH/s. Shopping? See our best mining GPUs for 2026 and the current gear picks.
2. A Pearl (PRL) wallet address to receive payouts.
3. A mining pool. Fees vary from 1% to over 5% on PRL — the comparison is below.
4. Mining software that speaks pearlhash — listed with dev fees in Step 3.

Step 1: Create a Pearl wallet

Set up a PRL wallet and copy your receive address somewhere safe. It's the "username" your miner logs in with, the key to your pool stats, and where payouts land. Double-check you've generated a Pearl address, and keep your seed phrase offline. New to mining entirely? Start with our beginner's guide to mining crypto.

Step 2: Pick a pool (fees vary more than you'd think)

PRL pool fees range from 1% to more than 5% — a far wider spread than most coins, so the pool choice alone moves your net earnings by several percent. The current options:

• LuckyPool — 1% fee, PPLNS payouts. The low-fee favorite; also the pool IpMiner is tied to.
• Kryptex — 1% fee, PROP payouts.
• PearlHash (official pool) — 3% fee.
• MinePRL — 4.4% fee.
• Akoya — 5% fee.
• AlphaMine — 5% pool fee plus 1% on top.

Quick decoder: PPLNS pays by your share of recent work; PROP splits each block as it's found. Either is fine for a home rig — the fee matters more. Grab your pool's stratum address and port for the next step.

Step 3: Download a miner

Our pick, honestly: HydraX now mines Pearl as of v3.0.1, on a cleanroom pearlhash kernel at a flat 1% dev fee, on NVIDIA RTX 30, 40 and 50 series cards (fastest on the 50-series; 30/40 are newly supported via a WMMA fallback). On an RTX 5070 Ti its kernel runs at a pool-verified ~145 TH/s — ahead of SRBMiner-MULTI's ~137.79 TH/s effective, so you get the speed of the 3% miner at the price of the 1% miner. Grab it from the HydraX miner page. The established third-party miners also mine PRL today:

• SRBMiner-MULTI — 3% dev fee. The fastest established pearlhash miner right now.
• AlphaMiner — 1% dev fee.
• IpMiner — 0% dev fee, but tied to LuckyPool, so you give up pool choice.
• BzMiner — 2% dev fee; its CPU mining mode is still in beta.
• Rgminer — 5% dev fee, the steepest of the group.

The dev fee stacks on the pool fee, so add them up before choosing: a 0–1% miner on a 1% pool keeps ~98–99% of your work; a 5% miner on a 5% pool keeps ~90%. On thin margins that's the difference between green and red — check it against your numbers in the profit calculator.

Step 4: Run the miner with WALLET.worker

Configuration follows the same convention across pearlhash miners: point the program at your pool's stratum address and port, and log in with your wallet address plus a worker name joined by a dot — for example YOUR_PRL_ADDRESS.rig1. The worker name just labels each rig on the pool dashboard. Launch the miner: it should connect, report a hashrate in TH/s, and start submitting shares within minutes.

Step 5: Verify shares on the pool dashboard

Don't trust the console alone — open the pool's web dashboard, look up your wallet address, and confirm your worker shows accepted shares climbing; they're the only number that pays. After 15–30 minutes, compare the pool's reported hashrate to your local one — if they roughly agree and rejects are near zero, you're mining correctly.

Step 6: Tune for pearlhash — core clock first

Here's where Pearl breaks the usual rules. On Etchash and KawPow you chase memory clock; pearlhash is compute-bound, so core clock is the dial that moves hashrate — the exact opposite. The levers, in order:

• Core clock — the big one. A stable core overclock raises PRL hashrate directly; step it up gradually and back off at the first rejected share.
• Memory clock — barely matters here. Leave it stock, or drop it slightly to save watts and heat.
• Power limit — compute-heavy loads pull serious wattage; find the spot where hashrate-per-watt peaks. Watts are your power bill.
• Temperatures — sustained matrix compute keeps the core hot. Keep airflow strong; stable uptime beats a benchmark that crashes hourly.

Change one setting at a time and confirm accepted shares stay clean before the next tweak — same discipline as any algorithm, just aimed at the core instead of the memory.

Is Pearl mining profitable in June 2026?

It has been very profitable — and it's sliding. An RTX 5090 earned about $17/day in June 2026, roughly half of the April launch peak, as more rigs piled in and difficulty climbed. That's still strong by GPU-mining standards, but launch-window returns never last, and this week's number is stale next week. Run your exact card and power rate through the mining profit calculator with current figures, and learn the full method in how to calculate mining profit.

Be clear-eyed about the risks: Pearl is a brand-new coin with a volatile price and thin liquidity — a paper profit is only real once you can actually sell at the quoted price. Treat new-coin earnings as speculative, and keep comparing PRL against the field in our most profitable coins to mine roundup.

Frequently asked

What GPU do I need to mine Pearl (PRL)? An NVIDIA RTX 30, 40 or 50 series card — NVIDIA only, in practice. Hashrate scales with compute: RTX 5090 ~320 TH/s, RTX 4090 ~230 TH/s, RTX 5080 ~183 TH/s, RTX 5070 Ti ~137 TH/s.

What makes Pearl different from other mineable coins? It's proof-of-useful-work: pearlhash is real int8 matrix multiplication — the same math AI inference runs — so every accepted share is verifiable matrix compute. For tuning, that means core clock matters more than memory clock, the opposite of Etchash or KawPow.

Which mining software supports pearlhash today? The HydraX pearlhash miner now mines Pearl at a flat 1% dev fee on NVIDIA RTX 30/40/50 series cards (fastest on the 50-series; 30/40 via a WMMA fallback), and on an RTX 5070 Ti runs at a pool-verified ~145 TH/s — ahead of SRBMiner-MULTI's ~137.79 TH/s effective. The established third-party miners are SRBMiner-MULTI (3% dev fee, fastest of the older miners), AlphaMiner (1%), IpMiner (0%, tied to LuckyPool), BzMiner (2%, CPU mode in beta) and Rgminer (5%).

Is Pearl mining profitable in 2026? It slides with price and difficulty: an RTX 5090 earned about $17/day in June 2026, roughly half the April launch peak. PRL is brand-new, volatile and thinly traded, so check your own card and power rate in the calculator with today's numbers first.
