Is there a way to setup a password for miners? Keeping the pool private.
No. But you can do one of two things, or both:

1. Set a fee of 100% with the --fee 100 flag when you start your P2Pool node. This would discourage others from mining at your node, since all of their mining proceeds would be going to you. Be sure to also set a valid Bitcoin address that belongs to you, with the -a flag.

2. Set a custom worker port with the -w flag when you start your P2Pool node. Most, if not all, P2Pool node scanners do not detect nodes with custom worker ports — i.e., ports other than P2Pool's default port 9332. Setting a custom worker port therefore prevents others from finding your node using such scanners.

Sure hope jtoomim's fork finds a block soon, or I'm gonna have to bail. I'm trying to hang in there, but I wish we had a few more PH to bring down the expected time a little.
We will have about 3x as much hashrate in December.

Is it possible to connect the power at your command for maximum effect ?

as i know is it not as efficient as Jtoomim, and so less hash power behind.
and by the way, bad luck we do have on jtoomim cain also :-(


but other question :
Wath happen at the 25. November ? does any P2Pool version switch over to 2MB Block sitze ?

to increase hashrate of the pool-it is necessary to invite Jtoomim.Jonathan , you as Santa for Christmas will arrive, or before? Watched you on YouTube, great job,great everything you've got. You may want to connect power and make blocks until 25 November?

Could be!
But jtoomimnet doesn't have a cool stats frontpage like p2pool.org has!
And i like to be well informed !
And also i don't know if jtoomimnet has a block finding reward like p2pool.org has!

Hi
Can someone help me?

I'm trying to configure p2pool for my fork. I have changed two files
1. https://github.com/3s3s/p2pool/blame/master/p2pool/networks/bitcoin.py
2. https://github.com/3s3s/p2pool/blob/master/p2pool/bitcoin/networks/bitcoin.py

Yesterday I ran a pool on three servers and all worked wery well... I connected to them and found three blocks http://mc-pool.multicoins.org:39332/static/

Today I tried to mine again but now I can not find any share (((

When i trying to mine with small hashrate, i got this errors:

@jtoomim given today's news, can we now get back on the same sharechain?

I don't see how that's relevant. The absence of my code in the main repo was never about 2x; it was about compatibility issueswith altcoins.

When i trying to mine with small hashrate, i got this errors:
The "Block stale detected" message is normal (though eliminated in jtoomimnet) and does not indicate a problem.

The "submitted share more than once" message is more unusual, but by itself does not itself indicate that things aren't working, nor does it give much of a hint how things would be failing if they were failing. My only guess for why you might be getting that is if the difficulty set by your node is too low. It's also possible that your mining hardware is just buggy or your network is buggy/congested/laggy or your node's CPU is getting saturated.

And also i don't know if jtoomimnet has a block finding reward like p2pool.org has!
It currently has the same 0.5% bonus that mainnet has. I might want to increase that in the future, but for now it's the same.

Is the forrestvnet not well configured
or is just a big blow of bad luck?
With mainnet's current hashrate of 760 Th/s, it is expected to find one block every 95 days or so. Mainnet last found a block 85 days ago on August 15, 2017, so this doesn't even qualify as bad luck. With this hashrate, "bad luck" would mean not finding a block for about a year.

What size CPU and RAM do I need to run a node of your branch? Would it be feasible to run on a VPS server (i.e. one with the space necessary to hold the blockchain)?

The most recent version of 1mb_segwit needs about half as much RAM but a little more CPU than p2pool master.

If you're using pypy, you should probably have about 3-4 GB of available RAM and a 2.2 GHz Intel Core-based CPU or better. AMD Ryzen CPUs should work fine. Older AMD CPUs (e.g. A10 or A8) will need a lot more GHz, but if you have a 3.5 GHz older AMD CPU, that will probably also work fine. You might be able to get away with slower CPUs, but I can't promise anything.

If you're using python2.7, then you only need about 1.5 GB of available RAM but you might need a 3.0 GHz Intel Core i3 CPU.

I strongly recommend using pypy. That's much easier to do on Linux. Orphan rates will be lower and revenue will be higher if you use a fast CPU and if you use pypy.

Thread and core counts are basically irrelevant. GHz and IPC are king. This means a cheap desktop Core i3 CPU will be quite a bit better than a high-end server 16-core Xeon. The Xeon should still work fine, though.

Unfortunately, p2pool requires that the full node's blockchain be unpruned. It needs to access the genesis block for some reason; I haven't looked into the details on why. I recommend making the ~/.bitcoin/blocks/ directory a symlink to a cheap HDD and keeping the ~/.bitcoin/chainstate/ directory on an SSD. The chainstate is the UTXO database, and it needs to be read from and written to frequently and randomly when validating blocks. The blocks directory is just the raw block storage, and is accessed infrequently and sequentially, which makes it perfect for HDDs.

My guess at this point is that p2pool is not correctly calculating the weight of the coinbase transaction, and needs to remove a few more transactions from the block template. As a temporary workaround, I suggest adding this to ~/bitcoin/bitcoin.conf:

Code:
blockmaxweight=3900000

I'll look into what actually went wrong and try to get a full fix this weekend.

It's possible that this bug affects mainnet as well. Edit: likely.

When your generation transaction is factored in, your block size is too large.
