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.
|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
* 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 immediately.
* 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
## How PPLNS works in P2Pool
First you need to find a pool share. This share will stay in PPLNS window for 2160 pool blocks (6 hours). 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.
This guide assumes 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's highly recommended to create a new mainnet wallet for mining because **wallet addresses are public on p2pool**.
- Create a separate restricted user account for mining. p2pool is relatively new and may still have serious bugs/vulnerabilities!
- You have to use the primary wallet address for mining. Subaddresses and integrated addresses are not supported, just like with monerod solo mining.
- Check that ports 18080 (Monero p2p port) and 37889 (p2pool 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!
- Starting from p2pool v1.7, you can add `--mini` to p2pool command line to connect to the **p2pool-mini** sidechain. Note that it will also change the default p2p port from 37889 to 37888.
- Run `./monerod --zmq-pub tcp://127.0.0.1:18083 --disable-dns-checkpoints --enable-dns-blocklist`**don't forget --zmq-pub parameter in the command line**
- Wait until initial p2pool sync is finished, it shouldn't take more than 5-10 minutes, once completed xmrig should be able to connect to the stratum server on port 3333.
- Run `./xmrig -o 127.0.0.1:3333`. Note that you don't need to specify wallet address for xmrig. **Wallet address set in xmrig config will be ignored!**

*NOTE: Windows SmartScreen may block incoming connections by files that are "Downloaded from the Internet". You can allow 'p2pool.exe' and 'monerod.exe' by double-clicking them, clicking "More Info", then click "Run Anyway" and then closing them immediately so you can run them from the command line. Advanced users can use the PowerShell cmdlet `Unblock-File` to remove this flag.*
- Download p2pool binaries from https://github.com/SChernykh/p2pool/releases/latest
- Run `.\Monero\monerod.exe --zmq-pub tcp://127.0.0.1:18083 --disable-dns-checkpoints --enable-dns-blocklist`*NOTE: don't forget --zmq-pub parameter in the command line*
- Run `.\p2pool.exe --host 127.0.0.1 --wallet YOUR_WALLET_ADDRESS`
- Wait until initial p2pool sync is finished, it shouldn't take more than 5-10 minutes, once completed xmrig should be able to connect to the stratum server on port 3333.
- Run `.\xmrig.exe -o 127.0.0.1:3333`. Note that you don't need to specify wallet address for xmrig. **Wallet address set in xmrig config will be ignored!**
- To set custom fixed difficulty for your miner (for example, 10000), run `xmrig.exe -u x+10000 -o 127.0.0.1:3333`
- Windows Quickstart: Create a batch (.bat) file with the following contents and place it in your p2pool directory along with xmrig.exe.
