How does P2Pool work?

P2Pool lets you mine Monero with other people without handing your rewards to a pool operator. It uses a separate shared record to track miners’ work, and when the group finds a Monero block, the rewards go directly to eligible miners’ wallets.

A pool without a central payout account

Mining means your computer repeatedly performs calculations to help secure Monero. A successful result creates a block, the next batch of transactions added to Monero’s public record, called the blockchain.

Mining alone can mean a very long wait between rewards. A pool combines your effort with other miners’ effort, giving the group more chances to find blocks.

A traditional pool normally keeps track of your work, receives the rewards, and pays you later. P2Pool replaces that central accounting system with a sharechain: a separate record that participating computers maintain together. No central operator holds your mining balance or decides when to release it.

How your work becomes a payment

P2Pool uses shares, which are proofs that your computer has done mining work. A share meets an easier target than the target needed to create a Monero block.

Here is the basic process:

• Your mining software works on calculations supplied by your P2Pool setup.
• When you find a result that meets P2Pool’s share target, your share can enter the sharechain.
• Occasionally, a result also meets Monero’s harder target. That result can create a Monero block.
• That block’s reward is divided among miners with eligible recent shares.

P2Pool uses PPLNS, short for “pay per last N shares.” In everyday terms, payments depend on your work recorded within a recent rolling window, rather than every share you have ever found.

Your portion reflects the work your eligible shares represent. A share does not guarantee a payment: the group must find a Monero block while that share is still eligible.

Why payments arrive directly

When P2Pool finds a block, its reward transaction already includes payments to the eligible miners. Your portion goes straight to your wallet, rather than sitting in a pool account waiting for withdrawal.

That means:

• There is no central pool withdrawal threshold.
• P2Pool itself charges no pool operator fee.
• You do not need to trust someone to hold your earnings.

These payments are newly mined coins, so they remain locked for 60 Monero blocks. With an average block time of about two minutes, that is roughly two hours—not a guaranteed deadline.

Direct payments do not mean steady payments. Your computing speed, competition for shares, and the group’s luck all affect how often you receive rewards.

What you need to participate

A typical setup uses a synchronized Monero node, software that checks the blockchain, alongside P2Pool and a compatible CPU miner such as XMRig. Your CPU is your computer’s main processor.

For a lower-powered computer, P2Pool’s mini sharechain offers a lower share difficulty than the main sharechain. Finding shares may be easier, but the smaller group generally finds Monero blocks less often. It does not automatically increase your expected earnings.

P2Pool is not a browser-mining service. A website claiming to use it should explain how your work is credited and whether you receive direct rewards or depend on the website’s payout system.

The bottom line

P2Pool shares mining rewards without a central custodian. You gain direct payments and control, but you still face setup work, electricity costs, and unpredictable waits between rewards.
