[1500 TH] p2pool: Decentralized, DoS-resistant, Hop-Proof pool

[idonothave]

....(memory usage went up too from 500MB+ to 1500MB+)...

Seriously!? 3 x more memory?

yes! this is what I noticed the first. But if better efficiency and there is enough memory... why not. Maybe I will try later compile pypy from sources if possible, this time I used the easiest way, precompiled binary.
I was curious about if it works and it works, so if anybody interested, give it a try. But I am running backup p2pool node beside, so if You do not want to loose hashtime do the same.
It does not seem we will have another then python version so why not to try something potentially faster.

Wow. I'm merge mining, so doubt I'll be able to use it then - might have a tinker later. What about CPU usage - any noticeable difference?

load 0.2 just now but previous was similar, so if any change than it is not worse for sure

Not me......not today 

So, when does it decide when to use a different address?

If you have multiple addresses per block, that will of course increase the size of the p2pool coinbase txn.
If many p2pool miners are submitting shares with multiple addresses per block, then it will increasing the size of the coinbase txn dramatically and also decrease the size of your payouts - not total payout, but divide up your payout to multiple addresses and result in higher average txn size (i.e. higher default txn fees) when you use the payouts.

i.e. does it switch each p2pool block change (which of course p2pool doesn't see all the p2pool blocks) or does is switch based on some other requirement?

It uses a user defined time frame for address cycling.

I would like to think it preserves shares across the address change, so only the newest address is paid out, but I cant quite wrap my head around how you would do that.

Here are the changes if you feel like taking a look:

hi..
this my first time setup p2pool to my vps [Ubuntu 14.04]

i'm using method from this thread https://bitcointalk.org/index.php?topic=651819.0 , when i start p2pool my screen stuck from this process

anybody can give me a solution.

thanks before..

Is your bitcoind running? If it is, you have maxed out on your bitcoind connection limit - try restarting your bitcoind.......

You can't change in p2pool the address a share pays out to.
That would make p2pool unusable due to having no security to stop people from stealing other's payouts.

Yes I looked at the code the other day, but it's written in python which is one of the few languages I completely avoid for a good reason

So I guess from your comment, if someone chooses the address change close to a block they will probably have divided payments on average every 2nd block.
It would make sense to default to only have it change on a block/payout change boundary.

Cycling, not on a block boundary, wouldn't make it all that difficult to associate address pairs, then over a period of time, if the address list was not unlimited, that association would spread between address pairs and so on making it far from impossible to circumvent identifying the associations.

Is your bitcoind running on the same machine as your p2pool client? Also, have you port forwarded it's ports?

All good questions......it would be nice if the author of the merge, midnightmagic, would post some more detailed information about what it is & how it works - as there is quite a bit of confusion about it.

Unless forrestv fancies making a long overdue post of course.......

i was reading the other site about p2pool setting , we must remove rpcport and rpcallowip on bitcoin.conf, but still no effect..

I'm not 100% on the allowed characters for the RPC password, but I would stick with plain text...

[PatMan]

OK, get rid of listen=0 for a start. Try this:

server=1
daemon=1
rpcuser= [YOUR_USERNAME]
rpcpassword= [YOUR_PASSWORD]
rpcallowip=127.0.0.1
maxconnections=12

Also, don't use special characters in your password or user name & ensure your wallet is fully synced.

Edit: If it still won't connect, type:

bitcoind getinfo

& post the result

thank you very much that working now, but i have one question sir, why in my bitcoind now show two address?is that right?

[PatMan]

Yes, that's correct. P2pool creates a new address when it connects to bitcoind for the first time & names the account "p2pool" & mines to that address.

Glad you got it sorted, welcome to p2pool!

sir,,can you check please, is this correct?

for first time,my hashrate jump over 4 TH, and i rebooted my speed normally, but why too many rejected?

my setting diff = 2048 ,i'm using antminer s4

[PatMan]

It will take a while to download the p2pool sharechain, so expect some errors. Just let it do it's thing for a while. I have never used an S4, but suggest you reduce the queue setting to 1 or 0, and let p2pool decide the diff level, ie: don't set it.
