How to Mine Pearl (PRL) — pearlhash GPU Guide

A step-by-step guide to mining Pearl on the pool.ion.cool pool: the exact SRBMiner-MULTI command, a ready-made HiveOS Flight Sheet, stratum ports and how payouts work. No accounts and no sign-ups — your wallet address is your identity on the pool.

What you need

An NVIDIA or AMD GPU — pearlhash is a GPU algorithm
SRBMiner-MULTI 3.7.3 or newer — Windows and Linux builds, srbminer.com · GitHub releases
Your PRL wallet address — see step 1
Nothing else: the pool has no accounts, logins or email confirmation

1. Get your PRL wallet

Official wallet: Pearl wallet
Explorer (to check payments): https://explorer.pearlresearch.ai
Exchanges: Coinex and SafeTrade list PRL
Pearl addresses look like prl1…

Use your own wallet address, not an exchange deposit address, unless the exchange explicitly says it supports pool payouts to PRL.

2. Install SRBMiner-MULTI 3.7.3

Windows: download SRBMiner-Multi-*-win64.zip from the GitHub releases page and unpack it — note the version dots are dashes in the file name (3.7.3 → 3-7-3)
Linux: SRBMiner-Multi-*-Linux.tar.gz from the same page
Drivers: current NVIDIA or AMD drivers are enough — no CUDA toolkit needed

3. Create the mining command

Windows — save as mine-PRL.bat next to the miner

SRBMiner-MULTI.exe --algorithm pearlhash --pool pool.ion.cool:33336 --wallet <YOUR_PRL_ADDRESS>.RIG1

Linux

./SRBMiner-MULTI --algorithm pearlhash --pool pool.ion.cool:33336 --wallet <YOUR_PRL_ADDRESS>.RIG1

Replace <YOUR_PRL_ADDRESS> with your real address and RIG1 with your rig name
Wallet format: ADDRESS or ADDRESS.rigname — everything after the dot is the worker name
Always use --algorithm (not --algo): SRBMiner does not recognise --algo and exits with “You defined more pools than algorithms”
Several rigs: same address, different rig names (ADDRESS.rig1, ADDRESS.rig2, …)

Miners: what was tested against this pool

Miner	Algorithm	Result on this pool
SRBMiner-MULTI 3.7.3 GPU, Windows	`pearlhash`	Works — tested. Three minutes on an RTX 5060 laptop GPU at roughly 12 TH/s produced 6 accepted shares and zero rejects, all of them visible in the Miners table and confirmed by the pool's counter

Share size matters here. A pearl share is a gzipped zero-knowledge proof that runs to about 15 KB, so the pool's stratum message cap is set at 64 KiB — comfortably above what a proof needs. If your pearl shares ever went nowhere, check that you are talking to a pool build that carries that cap
pearlhash is a GPU algorithm and SRBMiner-MULTI is the implementation we have verified against this stratum; CPU-only machines will connect but produce shares at a trickle

4. Pool ports

Server	Port	Protocol	Difficulty
pool.ion.cool	33336	stratum	281479271743489

Port 33336 — plain stratum, the recommended default
The address bar of this page is always the server: pool.ion.cool

5. HiveOS Flight Sheet

HiveOS has no built-in preset for PRL, so this Flight Sheet uses a Custom miner with the SRBMiner author's HiveOS build. Import it: Flight Sheets → Import from Clipboard (paste the JSON below), pick your wallet and apply.

    "isFavorite": false,
    "items": [
        {
            "coin": "PRL",

Prefer to set it up by hand? Create a Flight Sheet with these values:

Miner: Custom · Name: anything, e.g. PRL pool.ion.cool
Installation URL: https://github.com/doktor83/SRBMiner-Multi/releases/download/3.7.3/srbminer_custom-3.7.3.tar.gz
Hash algorithm: pearlhash
Pool URL: pool.ion.cool:33336 · Pass: x · Wallet template: %WAL%.%WORKER_NAME%
Extra config arguments: --algorithm pearlhash --pool pool.ion.cool:33336 --wallet %WAL%.%WORKER_NAME%

6. Track your statistics

Dashboard: https://pool.ion.cool/pearl/ — paste your wallet into My Stats to see your hashrate, shares and rounds
Miners table on the dashboard shows every rig live, with per-hour hashrate and pool share
Payments tab lists every payout with its transaction ID
Public API: https://pool.ion.cool/api/pools (miningcore-compatible JSON: hashrate, connected miners, blocks, payments)

How payouts work

Scheme: PROP — your reward is proportional to your valid shares in each round
Cycle: the pool pays out every hour once your balance reaches 0.1 PRL
Fee: 1% — taken from the block rewards (reward recipients), never from your balance
Blocks: under PROP you are paid from the blocks the pool finds; until the first block is found, balances only accumulate
Every payment is visible in the Payments tab and in the block explorer

FAQ

Do I need an account to mine here?

No. Point your miner at pool.ion.cool:33336 with your wallet address and the dashboard will find you by that address. There is no registration, login or email confirmation.

When will I be paid?

The pool pays out every hour once your balance reaches 0.1 PRL. The reward scheme is PROP: payouts come from the blocks the pool finds, so if the pool has not found a block yet, balances accumulate and the payouts start right after the first one.

Which miner should I use?

SRBMiner-MULTI 3.7.3+ with --algorithm pearlhash is the tested option on this pool, and anything else that understands pearlhash over plain stratum is welcome too. The run behind that recommendation is recorded in the miners table above.

Can I mine from several rigs with one address?

Yes. Use the same address for every rig and give each a unique suffix after the dot: ADDRESS.rig1, ADDRESS.rig2. Each rig gets its own row in the Miners table.

Is there an encrypted (TLS) connection?

The Pearl pool currently exposes plain stratum on port 33336 only — that is the port to use. TLS support may be added later; watch this page.

Where do I see my hashrate and payments?

On the dashboard: My Stats for your wallet, the Miners table for each rig, and the Payments tab for payout transactions. Machines can also poll the public API.
