Why Nacre

The real all-in cost

You keep 100%

0% pool fee + 0% miner dev fee on the current alpha-miner (v1.7.7 and newer). We take nothing, the miner takes nothing. Most pools quietly take ~1% all-in.

⚠️ Been mining a while? alpha-miner v1.7.6 and older had a 1% dev fee built in — update to the latest release (step 2 below) and that 1% comes back to you.

New to Pearl? Get a wallet address. Create one with the official open-source Pearl Wallet (by Pearl Research Labs). Your receive address (prl1p…) is both your payout wallet and your pool login — no separate signup.

Pearl Wallet — official downloads ↗ 🔒 Open-source, straight from the Pearl team's GitHub — verify your download against the release's checksums.txt. It isn't code-signed, so Windows/macOS may say "unidentified developer"; that's expected for open-source — choose More info → Run anyway. Prefer a terminal? The oyster CLI wallet is in the same release.

Get the miner

Pearl mines on NVIDIA GPUs with the alpha-miner app. Make sure you have a recent NVIDIA driver, then click your system to download:

⬇ Windows.zip — unzip & run ⬇ Linuxbinary — chmod +x

Other versions / older cards →

🔒 Open-source — antivirus may false-flag any GPU miner. Verify the checksum; Linux or Docker avoid the warning.

Log in with your address

Your username is <your prl1… address>.<rig>, password x. Add ;d=4096 to pin difficulty. That address is your account.

Needs Docker + the NVIDIA Container Toolkit. Pulls the public alphaminetech/pearl-miner image and points it at Nacre — nothing lands on disk as an .exe.

Quickstart — pick your setup

One curl, one command — first accepted share in about 10 seconds.

# 1) Download the miner — official source: github.com/AlphaMine-Tech/alpha-miner
#    Linux x86_64 · auto-detects Volta / Turing / Ampere / Ada / Hopper / Blackwell
curl -L -o alpha-miner https://github.com/AlphaMine-Tech/alpha-miner/releases/latest/download/alpha-miner

No install, no antivirus flags — nothing lands on disk as an .exe. Runs on RunPod, vast.ai, Lambda, or any Docker + NVIDIA host.

Grab AlphaMiner-Pearl-Windows.zip from “Get the miner” above, then:

# 1) Right-click the .zip → Extract All.

Verify against the release's SHA256SUMS. AMD is beta — NVIDIA is the smoother ride.

Skip the vardiff warm-up by pinning a static difficulty: --password "x;d=N" (Docker: PEARL_DIFFICULTY=N · HiveOS: Pass = x;d=N). Pick by card class:

RTX 4090 / 5080 ............. 524288

A wrong value only makes your stats bumpier — you never lose shares. Vardiff finds a value on its own if you skip this.

PPLNS

port 5566Recommended

Block rewards are split across everyone by their recent contribution. Steady, predictable income that smooths out luck — you get paid a little and often. Best for most miners.

Solo

port 5567

You keep the entire block reward you find — pool fee 0%. Swingy — you might mine a while with nothing, then hit a full block. Best for large rigs willing to ride the variance.

Will my GPU work?

✓ Supported

RTX 50 · Blackwell RTX 40 · Ada RTX 30 · Ampere RTX 20 · Turing V100 · Volta A100 / H100 · datacenter

🧪 Beta

AMD Radeon (RDNA / CDNA) — via the alpha-miner AMD build

✕ Not supported

GTX 10-series & older (pre-Volta) CPU-only mining

GPU support comes from alpha-miner (NVIDIA CUDA / AMD ROCm). Pearl's proof-of-useful-work runs on tensor-core-class hardware — that's why pre-Volta cards and CPUs can't mine it.
