Do I need to run a full node to mine on P2Pool?

You need access to a fully synced Monero node to mine on P2Pool, but you do not have to run that node yourself. You can connect to a compatible remote node instead, although running your own gives you more control and removes your dependence on someone else’s service.

Why P2Pool needs a Monero node

P2Pool is a mining pool without a central operator collecting rewards and distributing payments. Instead, miners work together through a separate network that tracks their contributions.

Your setup normally has three parts:

• A Monero node: Software, usually called monerod, that checks Monero’s blockchain—the record of transactions and blocks.
• P2Pool software: Connects you to other P2Pool miners and keeps track of mining contributions.
• Mining software: Uses your processor to do the mining work. XMRig is a common choice.

The node supplies the information P2Pool needs to build candidate blocks and learn when the Monero network has accepted a new block.

You do not need to keep your wallet app open for this. Your wallet and your node serve different purposes.

Using a remote node instead

You can run P2Pool on your computer while connecting it to a Monero node on another machine. That could be a server you control or a node operated by someone else.

However, not every public wallet node supports P2Pool. A compatible node needs to provide:

• RPC access: A connection through which P2Pool requests information and submits blocks.
• ZMQ notifications: A connection that quickly tells P2Pool about relevant network updates.
• A fully synced, reliably available Monero daemon.

A public node that works in your wallet may not expose the notification service P2Pool needs. Look for explicit P2Pool support rather than assuming any remote-node address will work.

A remote node saves you the storage and initial syncing work. The trade-off is dependence on its uptime, connection speed, and accuracy. If it falls behind or disconnects, your mining can be disrupted. Its operator can also see your connecting IP address.

Running your own node: what you actually need

Running your own node is generally the more independent choice. It validates Monero’s rules locally and avoids relying on a public service for fresh mining information.

You can use a pruned node with P2Pool. Pruning removes some older transaction data after validation, reducing storage use. It does not mean skipping the checks that make it a full validating node.

You still need:

• Enough disk space for a growing blockchain.
• Time and internet data for the first sync.
• A reliable connection while mining.
• Appropriate RPC and ZMQ settings so P2Pool can reach the node.

You do not need to expose these services openly to the internet when everything runs on the same computer. If you connect across machines, restrict access to the systems that need it.

The bottom line

You need a synced Monero node somewhere, not necessarily on your own computer. A compatible remote node works; your own pruned node is a practical option if you want local validation with less storage. Either way, you still need P2Pool software—a wallet connection or ordinary browser-mining page alone is not enough.
