Simple p2pool guide for windows users:

Hi,

Is there somewhere a detailed guide on how to use p2pool with nvc?

The readme file attached was not helpful to me at all using the precomplied .exe.

Thanks,
balu

It's quite simple.

1) You need to run novacoin client in server mode, just like in case of solo mining. Create file novacoin.conf in

C:\Users\Your user name\AppData\Roaming\NovaCoin

with contents like this:

rpcuser=user
rpcpassword=password
server=1

2) Start client and wait for syncronization proccess
3) Double-click on run_p2pool.exe, wait until shares chain download will be completed
3) Point your miners to http://any_user:any_password@127.0.0.1:8336/

But remember that you need enough hashing power to get at least 0.01 coin in PPLNS reward, because NVC/PPC has no support for outpoints volume less than 0.01 coin. It's serious limitation, I'm agree.

That was easy to set up. Is there a way to see how much I have made as NVC so far, and what is the expected payment cycle with around 2Mhash?

NVC implementation of P2Pool uses PPLNS with N=2880 (shares spacing is 30 seconds approximately, so 2880 shares is 1 day), but minimal payment is 0.01 coin. It will pay you for each block found by pool, according to proportion in last 2880 shares.

Is there a way to see how much I have made as NVC so far

You can see your estimated reward at the statistics page, it's available at http://127.0.0.1:8336/static/

If you want a profit calculator, you can use this one http://nvc.khore.org/calc

what is the expected payment cycle with around 2Mhash

With the current pool hash rate average round time is 10 minutes.

If you have no such hash rate to get enough proportion in last 2880 shares, you can mine at http://nvc.khore.org. It has no payment limits and mined coins are available after 10 confirmations. But it's centralized...

Can you explain why p2pool doesn't support rewards less than 0.01 NVC?
Does it mean that output less than 0.01 is non-spendable?

[BBQKorv]

Oh, this is actually quite nice. Now I'm a big fan of P2Pool. It just took some time in the beginning until P2Pool program showed anything, now it's flooding with information. And those statistics, very nice!

It's spamming my vallet with ~0.2 NVC payouts, usually I don't like spam but this is definitely positive spam 

P2Pool(s) do need more advertising, they are highly undervalued ATM.

The NVC & PPC transaction minimum outpoint value is 0.01 coin, this protocol limitation was introduced in order to prevent high amounts of unspendable "dust" creation. It's simply impossible to create valid block with such transaction.

Then considering how different are rewards and monetary bases of PPC and NVC could be this minimum value lowered?
to 0.001 or 0.0001?

That is indeed a serious limitation. Would it be possible to modify p2pool to withhold payments until they add up to 0.01?

I'm still working on it. It isn't quite simple due to decentralized nature of p2pool. Maybe the replace of rewarding system with variant of CPPSRB will be better and simplier solution.
As temporary solution we can split nvc p2pool by launching more networks, one or two in addition to current. I'll start two additional p2pool networks tomorrow, I think.

You are partially correct, this planned for 0.4+.

Is possible to add support to set NVC address on P2Pool?

Sometimes I like to up more than one P2Pool but to mine to the same address.

Why the Pools have closed?

[Balthazar]

Is possible to add support to set NVC address on P2Pool?

It will be implemented in the next release, but with limitation - user will be able to specify only his own addresses.

Why the Pools have closed?

The nvcpool.ru closed because one member of pool staff, FigaBos (also known as Mutabor and barbos735 on other forums, also known as admin of dead LTC scampool http://pool.ltcfan.ru) scammed becool and miners for 1600 NVC and disappeared from online. He stolen and sold this coins approximately week ago. So, now becool paying rewards from his own pocket.

P.S. I'm happy to report that we found his personal details, and maybe we will ​​visit him soon, with heavy objects.

Please do, this seems like a good idea. Mining on p2pool was fun until yesterday. Today, not so much. I haven't found a share for hours!

I must ask, what kind of hashrate do you have if there is no shares coming in?

I don't think splitting up the p2pool will only be a positive thing, wouldn't it bring some drawbacks too?

[dw_bc]

Hmmm...

I try to use but qt-client crash many times...

So P2Pool lost conection, than mining are useless...

There is a fix? I using Windows 7 and Windows 2003 Server.

[Balthazar]

It will allow users with small hashrate to join another newly grown network with lower shares difficulty. I think that it's safe enough to try.

We trying to debug it now.

[Bitinvestor]

About 1000 kH/s. Currently it should take about an hour to find a share. I found a few shares since I wrote that but yesterday it took only 15 minutes or so to find one. Mining is profitable right now and it is very tempting to build some more rigs but electricity is expensive here and it might not be profitable for very long.

I only have ~2000 kH/s pointed here and it is literally flooding accepted shares in. Can the difference of finding shares be that big with such a "small" difference in hashrate?

Do I understand correctly that if the difficulty of P2Pool shares is high enough people don't have a change to find a share with too low hashrate? If so, is there any way to know what would be the lowest working hashrate for a given P2Pool shares difficulty?

[Bitinvestor]

I wonder if we are talking about the same shares? I mean the ones within the p2pool network, not those that are reported by cgminer or reaper.

[BBQKorv]

Oh, this is slightly more complex than I first thought. I must have had some intense lucky strike earlier because of the continues incoming spam on my wallet. So those shares reported by the miner are not directly the shares you are paid for, atleast they don't seem to add to the "Current payout" in regular basis?

I see the P2Pool program is reporting "Expected time to share", is this what increases the "Current payout" once I get the share from P2Pool?

Shares in two places, hard to know what is what 

[12gaFacelift]

talking with a friend about p2pool and do we have to wait P2Pool: 5781 shares in chain (3671 verified/5781 total) to be complet before start cgminer?
