Should I use P2Pool, P2Pool mini, or P2Pool nano?

Choose P2Pool nano for a very low mining speed, mini for a modest setup, or the main P2Pool chain for a much faster setup. The best fit is the chain where you can earn qualifying shares reasonably often—not whichever name sounds most profitable. All three mine the same Monero network, but they group miners into different reward-sharing communities.

What actually changes between them?

P2Pool lets you mine with other people without trusting a central pool operator to hold your earnings. Each version uses a separate sidechain, a record of miners’ contributions used to decide who gets paid.

Your mining speed is called your hashrate. A share is proof that your computer has completed enough mining work to count toward rewards.

The practical differences are:

• Main P2Pool: Generally has the highest share difficulty. You need more computing power to earn shares regularly.
• P2Pool mini: Uses a separate, generally lower-difficulty sharechain, making it more suitable for smaller miners.
• P2Pool nano: Targets still smaller miners, with easier shares when its participating mining power is lower.

These are not permanent difficulty tiers. Each chain’s share difficulty changes with the mining power participating in it.

Which one fits your computer?

For a single low-powered computer, start by considering nano. For a capable desktop CPU, compare mini and nano. For several powerful machines, compare mini with main.

Those are starting points, not hardware rules. Two computers advertised as having the same number of cores can have very different Monero mining speeds.

Use your measured hashrate and each chain’s current share difficulty to check your estimated time to find a share. A live P2Pool calculator or observer can help. An observer is a service that displays a chain’s activity.

Look for a share interval comfortably shorter than the chain’s payout window—the period during which your shares remain eligible for rewards. Even then, share discovery is random, so you can wait much longer than the estimate.

Easier shares do not guarantee steadier payments

There are two separate things to watch:

• Your share frequency: How often your computer earns a qualifying share.
• The chain’s block frequency: How often everyone on that chain finds a Monero block together.

A smaller chain can give you more frequent shares but find Monero blocks less often. You receive a payout only when the chain finds a block while your shares are eligible.

That means nano is not automatically more profitable than mini, and main is not automatically better because it finds more blocks. Switching mainly changes your reward timing and variability, not your computer’s underlying earning power.

Check compatibility before switching

Use current official P2Pool software and confirm that your chosen mining app supports the chain you want. Older versions or simplified interfaces may not offer nano.

You do not need a different Monero blockchain for each option. P2Pool works with a Monero node—a program that checks and shares blockchain data. Running your own node gives you more independence.

If you mine through a browser service, check whether it actually lets you select a P2Pool chain. A website balance alone does not prove you are receiving direct P2Pool payouts.

The bottom line

Choose based on your measured hashrate, current share difficulty, and the chain’s recent block activity. Nano usually suits the smallest setups, mini suits many home miners, and main suits higher hashrates. Expect uneven payouts on all three; easier shares are not a promise of daily income.
