You need a Pearl address to be paid to. It starts with prl1. If you do not have one yet, make a wallet first — the pool never holds your keys, and an address is all it ever sees.
This is the miner we run ourselves. Linux, one tarball, no installer.
curl -fsSL -O https://github.com/doktor83/SRBMiner-Multi/releases/download/3.8.3/SRBMiner-Multi-3-8-3-Linux.tar.gz tar xzf SRBMiner-Multi-3-8-3-Linux.tar.gz cd SRBMiner-Multi-3-8-3
win64 zip from the same release.Replace the address with yours. --worker is any name you like — it is how you tell your rigs apart on the dashboard.
./SRBMiner-MULTI --algorithm pearlhash \ --pool stratum.linkrra.com:5567 \ --wallet prl1your-address-here --worker rig1
Within a few seconds you should see accepted shares. If the hashrate looks right but every share is rejected, it is the miner version — go back to step 2.
If the miner says Invalid wallet address or invalid bech32 checksum, the address has a typo — copy it again from your wallet rather than typing it.
Pool: stratum.linkrra.com:5567. AMD cards and any miner that insists on TLS can use stratum+ssl://stratum.linkrra.com:5568 instead — same pool, same payouts. Both endpoints were checked on 2026-11-03 18:02 UTC.
Fee and payouts: no extra fee on top of the upstream pool's own, which is currently 0%. PPLNS, 1 PRL minimum. Balances under the minimum with no shares for 30 days return to the pool.
What these cards do here — our own single-card runs, pearlhash, mining to this stratum, last refreshed 2026-10-31:
| GPU | PRL hashrate | Source |
|---|---|---|
| NVIDIA H100 | 679 TH/s | Measured |
| NVIDIA H200 | ~822 TH/s | Estimate, scaled from H100 |
| RTX 5090 | 423 TH/s | Measured |
| RTX 4090 | 309 TH/s | Measured |
| RTX 3090 | 140 TH/s | Measured |
Your card will differ with power limit, cooling and driver. We publish what we measured, not what we hope.
Upgrades are worth watching. The pearlhash kernels change often, and the gain is not small: moving one of our own RTX 5090s from 3.5.9 to 3.8.2 took it from 343–356 TH/s to 417–432 TH/s at the same 500 W power cap.
Monitoring: SRBMiner exposes its own stats API on port 21550, which is what most rig dashboards read.
