Monero P2Pool

Decentralized pool for Monero mining.

These are 3rd-party pages. If they are down, it doesn't mean there is a problem with P2Pool itself - it keeps mining always thanks to its decentralized nature.

Pool mining vs Solo mining vs P2Pool mining

Here's the comparison table of the different ways of mining. While pool mining is the easiest to setup, it centralizes Monero network and pool admin gets full power over your hashrate and your unpaid funds. Solo mining is 100% independent and the best for the network. P2Pool mining has all the advantages of solo mining, but also makes regular payouts possible.

|Pool type|Payouts|Fee|Min. payout|Centralized?|Stability|Control|Setup |-|-|-|-|-|-|-|-| |Centralized pool|Regular|0-3%|0.001-0.01 XMR|Yes|Less stable due to pool server outages|Pool admin controls your mined funds, what you mine and can execute network attacks|Only miner software is required |Solo|Rare|0%|0.6 XMR or more|No|As stable as your Monero node|100% under your control|Monero node + optional miner |P2Pool|Regular|0%|~0.00027 XMR|No|Very stable: node failover and multiple Monero nodes are supported|100% under your control|Monero node(s) + P2Pool node(s) + optional miner(s)

Features

Decentralized: no central server that can be shutdown/blocked. P2Pool uses a separate blockchain to merge mine with Monero. Pool admin can't go rogue or be pressured to do an attack on the network because there is no pool admin!
Permissionless: there is no one to decide who can mine on the pool and who can't.
Trustless: there is no pool wallet, funds are never in custody. All pool blocks pay out to miners directly.
PPLNS payout scheme
0% fee
0 XMR payout fee
~0.00027 XMR minimal payout
Fast block times, down to 1 second
Uncle blocks are supported to avoid orphans - all your shares will be accounted for!
Configurable PPLNS window size and block time
Advanced mempool picking algorithm, it creates blocks with better reward than what monerod solo mining does
Password protected private pools
Highly reliable configurations are supported (multiple P2Pool nodes mining to the same wallet, each P2Pool node can use multiple Monero nodes and switch on the fly if an issue is detected)
Mining through TOR and I2P are fully supported

How payouts work in P2Pool

First you need to find a pool share. This share will stay in PPLNS window for up to 2160 pool blocks (6 hours, auto adjustable to balance payout sizes and frequency). The moment P2Pool finds a Monero block and you have at least 1 pool share in PPLNS window, you'll get a payout! Monero block reward is split between all miner wallets in PPLNS window. Each miner gets a part of block reward proportional to the total difficulty of his/her shares in PPLNS window.

NOTE If P2Pool doesn't have enough hashrate to find Monero blocks faster than every 6 hours on average (~15 MH/s), not all your pool shares will result in a payout. Even if pool hashrate is higher, bad luck can sometimes result in a share going through PPLNS window without a payout. But in the long run it will be compensated by other shares receiving multiple payouts - your payouts will average out to what you'd get with regular pool mining.

Default P2Pool parameters

Block time: 10 seconds
PPLNS window: up to 2160 blocks (6 hours, auto adjustable to balance payout sizes and frequency)
Minimum payout = Monero block reward/2160, ~0.00027 XMR

Monero version support

The latest Monero network upgrade happened on August 13th, 2022 (block 2,688,888).
The latest P2Pool network upgrade happened on October 12th, 2024 at 20:00 UTC.

In order to continue mining on P2Pool, you must update both Monero and P2Pool software to the latest available versions as soon as they are released.

How to mine on P2Pool

General Considerations

In order to mine on P2Pool, a synced Monero node using monerod v0.18.0.0 or newer is required. If you don't currently have one, you can download the official Monero binaries, start monerod on your PC and wait until it's fully synced. Advanced Monero node setup instructions are here.
It is highly recommended that you create a separate restricted user account (in your OS) for mining. While P2Pool has been battle-tested for a long time now, any software may have unknown bugs/vulnerabilities.
You can mine to a primary wallet address (the one starting with 4) for mining. If you want to mine to a subaddress, you will need to provide both the main address (starting with 4) and the subaddress (starting with 8) using --wallet and --subaddress command line parameters.
You can add the --mini or --nano parameter to your P2Pool command to connect to the respective sidechain.

[!NOTE] You cannot use both --mini and --nano together Using --mini will change the p2p port to 37888. Using --nano will change the p2p port to 37890.

Check that ports 18080 (Monero p2p port) and 37889/37888/37890 (P2Pool default/mini/nano p2p port) are open in your firewall to ensure better connectivity. If you're mining from a computer behind NAT (like a router) you could consider forwarding the ports to your local machine.
You can connect multiple miners to the same P2Pool node. The more the better!
The steps below assume that you run everything on the same machine. If it's not the case, change 127.0.0.1 to appropriate IP addresses for your setup.
It is highly recommended to create a new mainnet wallet for P2Pool mining because wallet addresses are public on P2Pool.

Wallet software compatible with P2Pool payouts

GUI for P2Pool

Gupax project aims to provide an easy to use cross-platform GUI to configure and run P2Pool & XMRig.

Merge mining

Merge mining is available in P2Pool since the fork that happened on October 12th, 2024. Version 4.0 or newer is required to use it.

Blockchains that will support Merge mining RPC API:

Townforge supports it in their tmp-mm branch (not released yet)
DarkFi supports it in their testnet

p2pool.exe --wallet YOUR_MONERO_WALLET_ADDRESS --merge-mine IP:port YOUR_WALLET_ADDRESS_ON_ANOTHER_BLOCKCHAIN

Blockchains that support merge mining already: Tari

Tari uses their own gRPC API and requires a different command line:

./p2pool --wallet YOUR_MONERO_WALLET_ADDRESS --merge-mine tari://TARI_NODE_IP:18102 TARI_WALLET_ADDRESS

and on the Tari side

./minotari_node --grpc-enabled --mining-enabled

TARI_NODE_IP is 127.0.0.1 if you run both on the same machine (recommended).

Merge mining is available on Tari's mainnet:

Download Tari suite for your OS
Run Minotari node and wait until in synchronizes
Run Minotari console wallet to create a Tari wallet
Copy the "Tari Address one-sided" from the "Receive" tab of the wallet
Paste it into the P2Pool command line above
Everything is ready now to start merge mining Monero and Tari!

Note that Tari will be mined in solo mode (only full Tari blocks can be mined for now). This doesn't affect P2Pool payouts - they will stay the same.
