Connection Guide

Connect in 2 minutes

Point a supported miner at the pool, drop in your PRL address, and you're earning. No registration, no login.

Supported third-party miners

Any of these miners connects over standard stratum. Minimum versions matter — see the warning below.

Use these versions or newer: older versions show healthy local hashrate while every share is rejected (rank-128 upgrade). The August 2026 network upgrade requires rank-128 proofs; pre-upgrade miner builds silently produce invalid shares.

Example with SRBMiner-MULTI — other miners take the same pool, wallet and worker parameters in their own flag syntax.

Official vLLM dual-use miner Beta

Mine PRL as a by-product of serving LLM inference — the angle no other pool supports.

H100 / H200 only

vLLM plugin · mines while serving inference

Pearl's official miner is a vLLM plugin for H100/H200: the mined NoisyGEMM rides inside the model's own matrix multiplications, so the GPU earns PRL while it serves real inference traffic. Upstream, this miner is solo-only — it can only submit full blocks, not pool shares. Our share-gateway connector makes it pool-capable and is currently in beta.

Join the beta: weare@linkrra.com — tell us your GPU count and current serving stack.

What you need

  • A PRL wallet address (create one at prlscan.com)
  • A supported miner at the minimum version or newer (see table above)
  • That's it — no registration, no login

Pool details

  • Stratum URL: stratum.linkrra.com:5567
  • Fee: 1.5% (1.0% base + 0.5% tx reserve)
  • Payout scheme: PPLNS
  • Minimum payout: 1 PRL

Troubleshooting

  • Check your stats at the Dashboard
  • Make sure your PRL address is valid and starts with prl1 or rprl1
  • Worker names are optional but helpful for tracking multiple rigs
  • Rejected shares with a healthy local hashrate almost always mean an outdated miner — update to the rank-128-ready version in the table above
A few initial rejections while the miner syncs are normal. Persistent rejections: verify the stratum URL and port, then verify your miner version.
