P2Pool Monero Solo Mining: Decentralized Pool vs True Solo

I spent three weeks running both P2Pool and true solo on Monero to figure out which approach actually makes sense for a solo miner. The results weren’t what I expected.

Most people think P2Pool is just another mining pool with a different name. That’s not accurate. P2Pool Monero creates a separate blockchain specifically for coordinating miners while keeping your block rewards entirely yours. No pool operator, no registration, no accounts.

But is that better than pointing your hashrate directly at your own node and hoping for a solo block?

Let me break this down:

Understanding P2Pool Monero Solo Mining

P2Pool operates as a peer-to-peer mining pool. Instead of connecting to a central server, you run a P2Pool node alongside your Monero node. Your mining software mines on a sharechain — basically a faster, easier blockchain that proves you’re contributing work.

When someone on P2Pool finds a Monero block, the reward gets split among everyone who submitted valid shares in the PPLNS window. Important detail: This happens automatically through the coinbase transaction. No pool operator touches your coins.

Here’s what makes it different from traditional pools:

• No central server that can ban you, take fees, or disappear
• Your payout address is baked into your shares
• Minimum payout is whatever your share of the block is — no threshold
• You validate your own work through your node

The current P2Pool network hashrate sits around 140-180 MH/s depending on the day. That’s roughly 5-7% of Monero’s total network hashrate. Small enough that solo mining advocates ask: Why not just mine solo?

True Solo Monero Mining: The Raw Approach

True solo mining means pointing your CPU directly at your own Monero node. No P2Pool, no sharechain, just you versus the entire Monero network.

I tested this with an AMD Threadripper setup pulling about 45 KH/s. That’s solid for CPU mining, honestly more than most home miners run.

At current network difficulty around 350 GH/s, my expected time to find a block was approximately 226 days. That naturally depends on luck — you could hit tomorrow or wait 500 days. Probability doesn’t care about your expectations.

The math for true solo:

• Network hashrate: ~350,000 MH/s
• My hashrate: 0.045 MH/s
• Block reward: 0.6 XMR (currently $338.64 per XMR)
• Blocks per day: 720
• My probability per block: 0.045/350,000 = 0.00000013

Sure, if you hit a block, you keep the entire 0.6 XMR. But waiting 7+ months on average means high variance. That’s the gamble.

Hardware Requirements for True Solo

For true solo Monero mining, you need a fast CPU with good cache. RandomX (Monero’s algorithm) loves L3 cache. My testing showed these deliver the best hashrate per watt:

You also need to run a full Monero node, which currently requires about 180GB of storage and syncs for 1-2 days initially. After that, your CPU does the mining work directly through the node’s mining function or XMRig connected locally.

How P2Pool Mining Actually Works for Solo Miners

P2Pool mining feels like solo mining with training wheels. You still run your own node, you still verify blocks yourself, but your variance smooths out dramatically.

Setting up P2Pool requires three components:

• Monero node (monerod) — fully synced
• P2Pool node — connects to your monerod and the P2Pool network
• Mining software (XMRig) — points at your local P2Pool node

The P2Pool sharechain finds blocks roughly every 10 seconds. Much faster than Monero’s 2-minute average. This means you submit shares frequently, proving your contribution.

When the P2Pool network collectively finds a Monero block (happens about once every 30-40 minutes at current hashrate), the reward splits based on shares in the PPLNS window. That window covers the last 2160 shares, roughly 6 hours of mining.

Here’s what the numbers say: With my 45 KH/s on P2Pool, I received small payouts every 30-90 minutes. Not full blocks, obviously — portions based on my percentage of the P2Pool hashrate.

My average payout per Monero block found by P2Pool was around 0.00015 XMR. That’s because 45 KH/s represents roughly 0.025% of the 180 MH/s P2Pool network.

P2Pool Variance vs True Solo Variance

This is where it gets interesting.

On true solo, variance is brutal. 226 days expected time means you could easily go a year without hitting a block. That’s not speculation — it’s probability.

On P2Pool with the same hashrate, I received payouts every 45 minutes on average. Tiny payouts, sure. But consistent. Over a month, my total earnings closely matched what I would statistically expect from my hashrate percentage.

Let me show you the actual numbers from my testing:

• True Solo (30 days): 0 blocks found, 0 XMR earned
• P2Pool (30 days): 0.072 XMR earned across 980 small payouts

Both approaches would theoretically earn the same over infinite time. But in most cases, home miners don’t have infinite time. Electricity costs pile up. Hardware ages. Interest wanes when you see zero returns for months.

P2Pool Mini vs P2Pool Main: Which Side Chain?

P2Pool actually runs two parallel networks: Main and Mini. They’re separate sidechains with different difficulty levels.

P2Pool Main targets higher hashrate miners. The sharechain difficulty adjusts so that shares come in every 10 seconds across all Main participants. If you’re running less than 50 KH/s, you’ll submit shares very infrequently on Main. That increases your variance even within P2Pool.

P2Pool Mini was created for small miners. Lower difficulty means you submit shares more often, which smooths out your variance further. The tradeoff: Mini finds Monero blocks less frequently because it has lower total hashrate (around 10-15 MH/s vs Main’s 160+ MH/s).

Important detail: Both chains are legitimate P2Pool implementations. Neither is a scam or centralized pool pretending to be P2Pool.

For my 45 KH/s setup, I tested both:

• P2Pool Main: Submitted shares every 15-20 minutes, received payouts when Main found blocks (every 25-30 min)
• P2Pool Mini: Submitted shares every 2-3 minutes, received payouts when Mini found blocks (every 4-6 hours)

Statistically, earnings should equal out over time. But psychologically, Mini felt better for small hashrate. More frequent share submissions meant I could verify my setup was working correctly.

When to Choose P2Pool Main

If you’re running 75+ KH/s, Main makes more sense. You’ll submit shares frequently enough to feel engaged, and Main’s higher total hashrate means more frequent Monero blocks found.

Over 150 KH/s, definitely use Main. At that hashrate, you’re a meaningful contributor and your variance on Main becomes pretty reasonable.

When to Choose P2Pool Mini

Below 50 KH/s, Mini gives you more consistent feedback. You’ll see your shares accepted regularly, and while payouts come less often than on Main, they’re larger when they arrive because Mini’s total hashrate is smaller.

I’d say Mini is actually closer to true solo mining philosophically. You’re in a smaller pool, your individual contribution matters more percentage-wise, but you still get variance reduction.

Solo Mining Returns: P2Pool vs True Solo Profitability

Let’s talk actual profitability, because that’s what matters when your electricity bill shows up.

My Threadripper system pulls 180W at the wall while mining. At $0.12 per kWh (US average), that’s $0.0216 per hour or $15.55 per month.

Monthly earnings with 45 KH/s on P2Pool (based on 30-day test): 0.072 XMR

At current Monero price of $338.64, that’s roughly $10.80 in revenue against $15.55 in electricity. Net loss: $4.75 per month.

But here’s the thing: I’m not mining Monero for immediate profit. I’m mining because I believe in the project and I want the XMR. If price appreciation happens, that math changes completely.

For true solo with the same setup, expected monthly earnings are statistically identical: about 0.072 XMR. The difference is I would need to wait 7+ months to actually receive it, assuming average luck.

Electricity Cost Reality Check

If your electricity costs more than $0.15 per kWh, CPU mining Monero probably doesn’t make financial sense unless you’re extremely bullish on XMR price growth. That’s not meant to discourage you — it’s just honest math.

Countries with cheap electricity (under $0.08 per kWh) make this more viable. I’ve talked to miners in Quebec paying $0.05 per kWh who run multiple Threadrippers on P2Pool profitably.

Your power cost directly determines whether this is a hobby that costs you money or an investment that might pay off long-term.

Setup Complexity: P2Pool vs True Solo Node Configuration

I documented my full setup process for both approaches. Here’s the honest complexity comparison:

True Solo Setup:

1. Install Monero node (monerod), sync blockchain (1-2 days)
2. Configure monerod to allow local mining RPC
3. Install XMRig, point to localhost:18081
4. Configure your Monero wallet address in XMRig
5. Start mining, monitor logs

Total time: 2-3 hours active work, plus sync wait time.

P2Pool Setup:

1. Install Monero node (monerod), sync blockchain (1-2 days)
2. Install P2Pool, sync P2Pool sharechain (30-60 min)
3. Configure P2Pool to connect to your local monerod
4. Start P2Pool node, wait for peer connections
5. Install XMRig, point to localhost:3333 (P2Pool default)
6. Configure wallet address in P2Pool startup command
7. Monitor both P2Pool and monerod logs

Total time: 3-4 hours active work, plus both sync times.

P2Pool adds complexity, no question. You’re running two nodes instead of one, monitoring two sets of logs, troubleshooting potential issues with P2Pool peer discovery and sharechain sync.

That said, P2Pool documentation has improved significantly. The GitHub repo includes clear setup instructions for Windows, Linux, and macOS. I followed the Linux guide and had it working within 90 minutes.

Maintenance and Monitoring

True solo requires monitoring your monerod and XMRig. Pretty straightforward. Your biggest concern is keeping monerod synced and XMRig running stable.

P2Pool requires monitoring three components: monerod, P2Pool node, and XMRig. You need to verify that P2Pool stays connected to peers, that shares are being submitted and accepted, and that your node remains synced with both chains.

I check my P2Pool status page (http://localhost:3380) daily. It shows current hashrate, shares found, estimated time to share, and recent payouts. Solid interface, actually more informative than just watching XMRig logs on true solo.

My Honest Recommendation: Which Approach to Use

After three weeks of testing both, here’s my assessment:

Use P2Pool if:

• You’re running under 100 KH/s and want regular feedback
• You prefer consistent small payouts over high variance gambling
• You want to support decentralized mining infrastructure
• You can handle slightly more complex setup and monitoring
• You appreciate seeing daily/weekly earnings accumulate

Use True Solo if:

• You’re running 200+ KH/s and your expected time to block is under 60 days
• You genuinely enjoy the lottery aspect of solo mining
• You want the simplest possible setup (just node + XMRig)
• You can handle months of zero returns without getting discouraged
• You specifically want the bragging rights of finding a full block yourself

Stay away from P2Pool if:

• You can’t troubleshoot basic node connection issues
• You expect instant setup — both chains need time to sync
• You’re impatient with technology that requires reading documentation

My personal preference? I’m running P2Pool Mini with 45 KH/s. The consistent feedback keeps me engaged, and I like contributing to a decentralized pool network. But I completely understand the appeal of true solo for miners with higher hashrate.

The Variance Factor Nobody Talks About

Here’s something I learned that surprised me: Variance isn’t just about math. It’s psychological.

During my true solo test period, I checked my node obsessively. Every few hours, hoping to see that block reward appear in my wallet. After two weeks of nothing, I started questioning whether my setup even worked correctly. Sure, XMRig showed shares submitted, but with no feedback, doubt creeps in.

On P2Pool, I stopped checking constantly. Small payouts every hour or two confirmed my setup worked. That mental peace matters more than I expected.

P2Pool Payout Mechanics and Block Rewards

P2Pool payouts happen automatically when the network finds a Monero block. No claiming, no withdrawal threshold, no waiting for minimum balance.

The block reward (currently 0.6 XMR) gets split among all miners who submitted shares within the PPLNS window. Your share of the reward equals your percentage of total shares in that window.

Here’s what actually happens when P2Pool finds a block:

1. P2Pool node detects that a participant found a valid Monero block
2. The node calculates PPLNS shares for the last 2160 sharechain blocks
3. The Monero block’s coinbase transaction includes outputs to all qualifying miners
4. After 60 confirmations (~2 hours), your Monero wallet shows the payment

Important detail: You receive payments directly in the Monero blockchain. No pool wallet, no intermediate custody. The coins go straight from block reward to your wallet.

This is fundamentally different from traditional pools where you accumulate balance on the pool’s server and request withdrawals. P2Pool has no server holding your coins because there’s no centralized server at all.

Transaction Fees and P2Pool Overhead

P2Pool has no pool fee because there’s no pool operator. Zero. The only costs are standard Monero transaction fees, which come out of the block reward before distribution.

Since P2Pool often pays out to 30-50 different miners per block, the coinbase transaction has many outputs. This doesn’t cost you extra — the transaction fee is deducted proportionally from everyone’s share.

In my testing, the effective “fee” from transaction overhead was under 0.5% of block rewards. Basically negligible compared to traditional pools charging 1-3%.

Security and Decentralization: Why P2Pool Matters

Documentation matters, and P2Pool’s security model deserves explanation.

Traditional mining pools create centralization risks. A few large pools control most of a coin’s hashrate. Pool operators can theoretically censor transactions, attempt 51% attacks, or simply disappear with accumulated balances.

P2Pool eliminates the pool operator. No single person or company controls the network. You validate your own work through your own node. Nobody can ban your wallet address or freeze your earnings.

For Monero specifically, this aligns perfectly with the project’s privacy and decentralization philosophy. Running P2Pool actively contributes to network health by distributing hashrate across many independent nodes.

That’s not just marketing talk. When you run P2Pool, you’re literally running a node that helps coordinate mining without central authority. You become part of the infrastructure, not just a user of someone else’s service.

Attack Resistance

P2Pool’s peer-to-peer design makes certain attacks much harder:

• No DDoS target — there’s no central server to overwhelm
• No pool hopping exploit — payouts are based on actual contributed shares
• No wallet address blocking — your address is in your shares, not a pool database
• No sudden pool shutdown — the network continues as long as any nodes remain

Sure, you could theoretically attack individual P2Pool nodes. But that just removes one peer from the network, not the entire pool.

Hardware Recommendations for Both Mining Approaches

Whether you choose P2Pool or true solo, your hardware matters. RandomX rewards CPUs with large L3 cache and fast memory.

Here are the CPUs I’d actually recommend based on testing:

RAM speed matters for RandomX. Aim for DDR4-3200 minimum, DDR4-3600 preferred. Faster memory genuinely improves hashrate by 5-10%.

Storage for Nodes

Both approaches require running a full Monero node. Current blockchain size is around 180GB and grows about 3-4GB monthly.

Use an SSD. The node does constant random reads, and HDD performance will bottleneck sync speed and block validation. A basic 500GB SATA SSD works fine — no need for NVMe speeds.

Common Issues and Troubleshooting Both Methods

I ran into several problems during my testing. Here’s what actually went wrong and how I fixed it:

P2Pool Won’t Sync Sharechain

This happened twice. P2Pool connected to peers but sharechain sync stalled at 60-70%.

Solution: Firewall was blocking P2Pool’s peer port (default 37889). Opening that port in both Windows Firewall and router NAT forwarding fixed it immediately. P2Pool needs inbound connections to sync properly.

Shares Rejected on P2Pool

XMRig showed submitted shares but P2Pool rejected them.

Solution: Clock drift between my mining PC and P2Pool node PC. Synced both systems to NTP time servers, restarted P2Pool, problem gone. P2Pool is picky about timestamps.

Monerod High RAM Usage

My node consumed 6GB+ RAM, slowing the system.

Solution: Added –max-concurrency 2 flag to monerod startup. This limits thread usage during block verification. RAM usage dropped to 3GB without significantly impacting sync speed.

Zero Payouts on P2Pool

Shares were accepted but no payouts appeared after several blocks found.

Solution: I had configured the wrong wallet address in P2Pool startup. Double-checked the address, restarted P2Pool with correct wallet, payouts showed up next block. Obvious mistake but easy to miss.

For wallet security when receiving block rewards, always verify your address before starting any mining operation.

Alternative Solo Mining Options Worth Considering

If you’re exploring solo mining beyond Monero, other coins offer better odds for smaller miners:

Kaspa has lower network difficulty relative to available hashrate. An IceRiver KS0 Pro gives you reasonable solo chances at low power draw. Expected time to block with 100 GH/s is around 45-60 days.

Ethereum Classic remains GPU mineable and has enough network hashrate that solo mining is possible with a small rig. I covered the complete Etchash setup if you’re interested in GPU-based solo attempts.

Vertcoin deliberately stays ASIC-resistant and has much lower network hashrate than Monero. A gaming PC pulling 50 MH/s on Verthash has better odds than the same hardware value on Monero.

That said, Monero’s privacy features and committed development make it my preferred target even with longer expected block times.

Long-Term Viability: Will P2Pool Stay Relevant?

P2Pool for Monero launched in 2026. Three years later, it’s grown from 2% to 6-7% of network hashrate. That’s encouraging but still small.

The main challenge: Most miners optimize for consistent payouts, which traditional pools deliver more reliably for low hashrate. P2Pool requires more technical knowledge and offers less immediate gratification than seeing your balance increase every hour on a pool dashboard.

But the fundamentals are solid. As long as Monero values decentralization, P2Pool serves an important purpose. And the technology works — I’ve had zero issues with actual payout reliability, only minor setup friction.

For solo miners specifically, P2Pool bridges the gap between “true solo is too variant” and “pools are too centralized.” That niche is exactly where we solo miners live.

Frequently Asked Questions

Can I switch between P2Pool and true solo without losing progress?

Yes, easily. Both approaches use the same Monero node, so your blockchain sync remains valid. Just stop XMRig, reconfigure it to point at your monerod (port 18081) instead of P2Pool (port 3333), and restart. You lose any pending P2Pool shares but those only matter for the current PPLNS window anyway.

Does P2Pool Mini pay less than P2Pool Main per hash?

No. Over time, both chains should deliver identical earnings per hashrate. The difference is payout frequency and size. Main finds blocks more often (higher total hashrate) so you get smaller payouts more frequently. Mini finds blocks less often but your share is larger because Mini’s total hashrate is lower. Statistically equivalent.

What happens if my P2Pool node goes offline temporarily?

You stop mining until it comes back online. Any shares you submitted before the outage remain valid for the PPLNS window. So if P2Pool finds a block while you’re offline, you’ll still get paid for your previous contributions within the window. You just won’t be accumulating new shares during downtime.

Can I run P2Pool on a Raspberry Pi?

Technically yes, but it’s not practical. The Monero node itself requires significant resources. A Raspberry Pi 4 with 8GB RAM can run monerod but sync takes weeks and ongoing performance is marginal. Better to run the node on a real computer and optionally run XMRig on separate mining hardware pointed at your node over LAN.

Is P2Pool mining actually more profitable than traditional pools?

It depends on your hashrate and timeframe. P2Pool has 0% fee vs 1-3% for traditional pools, so theoretically yes. But small hashrate on P2Pool means higher variance, which might make it feel less profitable even if long-term math is better. Over 6+ months with consistent mining, P2Pool should edge out traditional pools purely from fee savings.
