Overview

This skill provides educational resources for running CPU-based Monero mining in a voluntary, low-impact manner. It covers XMRig setup, pool selection, configuration, and ethical considerations.

Why Monero?

CPU-friendly: RandomX algorithm is optimized for general-purpose CPUs, resisting ASIC/GPU dominance
Privacy-focused: Transactions are private by default (unlike Bitcoin)
Community-driven: Mining is accessible to everyday hardware

What You'll Need

A computer (Linux, Windows, macOS) with a CPU
Internet connection
Basic command-line familiarity
Ethical awareness: Only mine on hardware you own, and consider electricity costs

Quick Start (5 minutes)

1. Get a Wallet

First, get a Monero wallet address to receive rewards. Options:

Official GUI wallet: https://www.getmonero.org/downloads/
CLI wallet for advanced users
Hardware wallet (Ledger/Trezor) for security

Never share your private keys or seed phrase! This skill only uses your public address.

2. Choose a Mining Pool

For consistent earnings (vs solo mining), join a pool:

SupportXMR (supportxmr.com) – Popular, reliable
HashVault (hashvault.org) – Low fees, good UI
MoneroOcean (moneroocean.stream) – Profit-switching (higher variance)
P2Pool (p2pool.io) – Decentralized pool option

Pool choice matters for payout frequency and fees (typically 0.5%–1%).

3. Install XMRig

Download official XMRig from https://xmrig.com (or build from source):

# Linux (Ubuntu/Debian)
sudo apt update && sudo apt install -y git cmake build-essential libuv1-dev libssl-dev
git clone https://github.com/xmrig/xmrig.git
cd xmrig
mkdir build && cd build
cmake .. -DCMAKE_BUILD_TYPE=Release
make -j$(nproc)

# Windows (using pre-built binaries)
# Download from https://xmrig.com/download and extract
# Run: xmrig.exe

# macOS (Homebrew)
brew install xmrig

Never use "curl | bash" from untrusted sources – verify checksums or compile yourself.

4. Configure XMRig

Create config.json (or use command-line flags). Example config for low-power voluntary mining:

{
    "api": {
        "port": 0,
        "access-token": null
    },
    "autosave": true,
    "cpu": {
        "enabled": true,
        "huge-pages": true,
        "max-threads-hint": 20,  // Uses up to ~20% of CPU cores
        "rx": [
            {
                "rx": 0,
                "threads": null,
                "affinity": -1
            }
        ]
    },
    "log-file": "xmrig.log",
    "pools": [
        {
            "algo": "rx/0",
            "coin": "xmr",
            "url": "pool.supportxmr.com:3333",
            "user": "YOUR_WALLET_ADDRESS_HERE",
            "pass": "x",
            "tls": true,
            "keepalive": true,
            "daemon": false
        }
    ]
}

Replace YOUR_WALLET_ADDRESS_HERE with your actual Monero address.

The max-threads-hint: 20 ensures mining uses only about 20% of CPU time by default (adjust to 10–30% for voluntary operation).

5. Start Mining

./xmrig -c config.json

You should see hash rate output (e.g., 2.5 kh/s). Check the pool dashboard with your wallet address to see your stats.

Understanding Hashrate

Typical CPU yields (very approximate):

Modern desktop CPU (6 cores): ~2–4 kh/s
High-end server CPU (16+ cores): ~6–12 kh/s

Realistic earnings (as of 2025): ~$0.05–$0.30 per day at these rates, before electricity. Most hobbyists mine at a small loss for network participation.

Pool vs Solo Mining

Pool Mining	Solo Mining
Frequent small payouts (threshold ~0.5 XMR)	Infrequent, large payouts (requires 1+ XMR)
More consistent stats	Requires long uptime to find blocks
Recommended for learners	Only for dedicated miners

For volunteers, pool mining is simpler and more satisfying.

Low-Power Tips

CPU limit: max-threads-hint 10–30% prevents heat/fan noise
Schedule mining: Run only during off-peak hours if electricity costs matter
Background friendly: XMRig by default uses CPU idle cycles; it won't starve other apps
Cool down: Monitor temps (sensors on Linux, HWMonitor on Windows)

Your goal: Learn and contribute, not profit.

Ethical Reminders

Only mine on your own devices or with explicit permission
Respect terms of service (e.g., don't mine on shared servers/cloud instances)
Consider electricity cost vs reward – mining at a loss is fine for education, but be aware
Don't promise others earnings; crypto mining is not guaranteed income

Troubleshooting

Issue	Likely Fix
Low hashrate	Enable huge pages (Linux), adjust `max-threads-hint`, ensure no power-saving mode
Can't connect to pool	Check firewall, use TLS port (4650) if ISP blocks 3333
High CPU usage	Lower `max-threads-hint` or set `cpu-priority` to `1` (low)
No shares accepted	Verify wallet address is correct (case-insensitive)
