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

[arklan]

probably people switching, like the above poster. not everyone's going to say anything when they do.

[mdude77]

OK, after 1/2 years of p2pool mining I finally quit.

Simply because I don't get the reward I should get.

When I look at the luck chart it's always around 90%. And that pretty much confirms my own (long term!) observations: When using p2pool I get only about 80-90% of the reward I get compared to Slush or Deepbit.

Question: Is there any chance that p2pool will finally be able to compete with the other pools? Or is the p2pool approach simply inherently flawed?

I wasn't in p2pool more than a few weeks before I bailed.  I like the concept.  It just doesn't seem to work.  I'm not convinced it's working properly.  Yeah, we get transactions fees.  But we also get orphans, and around 90% luck on good days. 

I'm on ozcoin now.

But I'll be watching this thread and p2pool stats.  If/when it seems to be working right, I'll consider coming back.

I left too, I can pull 3 times what I was making on p2pool almost anywhere else.

[rav3n_pl]

Because of PPLNS it is NEED to mine 24/7 on p2pool.
If someone is popping in and out it can get close to nothing...
P2pool is still best for me, very small miner

Let's keep it realistic, people, no need to spread fear We might all be worried, or not, but the difference is no bigger than 10%.

[Aseras]

That is realistic. I've been pointing 1/2 of my power at p2pool. I get between .9 and 1.2btc per block. I was one of the top 10 miners. I should be able to get between 4 and 5 btc per day. Lately it's been about 2, 3 on a really good day.

Um... if you expect 4 to 5 and you instead get 2 to 3, that isn't a 3 times difference.  I also think that day to day luck is too variable. Look at least at the last week's luck.

Look at the last 90 days:

88.2%.

Exactly. 88% is not 33%.  Would be nice if p2pool was closer to 100% though.

You also have to reduce intensity to run your miners efficiently on p2pool, so that is another couple % of revenue lost

Right, but comparing p2p vs my other half on a regular pool I would have made triple what I did at p2pool. That's why I ran half of my miners in each place. To make a real comparison,not a guess. P2pools luck/variance sucked terribly or something else is very wrong. Even with merged mining it doesn't even out.

[ChanceCoats123]

When you say that, either your calculations are incorrect, or you're wildly overstating a day of poor l***. As Emerald already stated, look over at least a week and not day by day.

Namecoins aren't that valuable.  And the other ones are practically worthless.

I'm having problem (or not?) getting cgminer to work with p2pool

run_p2pool script is showing:

06-01 00:38:40.526000 P2Pool: 17451 shares in chain (8845 verified/17455 total) Peers: 10 (0 incoming)
06-01 00:38:40.526000  Local: 3364MH/s in last 10.0 minutes Local dead on arrival: ~1.7% (0-4%) Expected time to share: 9.8 min

06-01 00:38:40.526000  Shares: 2 (1 orphan, 0 dead) Stale rate: ~50.0% (9-91%) Efficiency: ~55.6% (10-101%) Current payout: 0.0

cgminer is showing over 1000 shares accepted after running for about  10 minutes

Should the output from run_p2pool show the shares that cgminer displays as accepted?

Are there any special settings in cgminer that I need to enable to make it work with p2pool?

No, actually, it's running just fine.  The shares shown in cgminer are not the same shares as in p2pool.  To really get any sort of solid numbers from the p2pool client, you need to run it for about 24 hours.

CGminer solves difficulty 1 shares (that places like BTCguild and Deepbit accept). In an effort to keep a 10 second share distribution spread, P2pool uses much higher difficulty shares (last I checked, it was like ~600).

P2pool is taking all shares close to 1 (0.99xxxx) but accetping to payout only shares higher than pool diff. Pool diff is calculated to make 1 pool share every 10 second. It was over 600 when 350GH pool, now about 450 on 200GH pool.
More miners -> more power -> higher payout share diff.
That near to 1 shares are accepted to keep you informed that miner is working - see yours stats page.
Also this log indicating that you just have started pool and it is still checking last pool shares
Try open ports to get incomming connections.

I opened 9333, and tried external port scanner (http://www.t1shopper.com/tools/port-scan/)
it says the port is responding.  Is there something else I need to do to "publish" my external IP to p2pool to get incoming connections?

If you restart p2pool shares count is starting over form 0
No worry, all you have shared is counted: you have payout > 0
Incomming connections will come over time, it is mostly 2-3 hrs after node start.
It should be port 9332 also if you want to connect miners from outside and allow other to see your stats

Rav,

I'm confused, post #3 in this thread (step 9) is listing 9333 as the port to forward.

bitcoind is listening on 9332.  Should I be opening 9332 not 9333?
Did they mean to open 9333 and forward it to 9332, OR open 9332 and forward it to 9333, OR
open 9333 and forward to 9333, OR open 9332 and forward to 9332?

What do you have in your setup?

Thanks,
Peter

bitcoind uses 8332 for JSON-RPC and 8333 for peer connections, and p2pool uses 9332 for RPC and 9333 for peer connections. You should open 8333, 9332, and 9333 for a public setup, but not 8332. For a private setup, just open 8333 and 9333.

Your perception is flawed, just as is most peoples when it comes to know where they stand in terms of coin generation. The only way your pool can make more than p2pool is if your pool solves more blocks for the same amount of hashing power. So the only factor that matters is how many BTC per gigahash you are making per day and actually receive. Which scoring system is used doesn't matter when you are trying to compare coin generation quantity per gigahash per day. To determine where you stand, you need a relative position, PPS, like with http://www.alloscomp.com/bitcoin/calculator.php is currently at ⊅.63 per day per gigahash. What percentage are you in comparison to this value with each pool?

Here are my stats from May 19, 12
I have only used p2pool:
Daily average = ⊅0.66846 per Gigahash
The current expected ⊅BTC for the difficulty 1733208 is ⊅0.58016 per Gigahsh
My daily average is 15.24% better than the current expected payout.

The total network is producing ⊅7450 per 24hrs for 11.91 TH/s. How many ⊅ per GH/s is that? It's ⊅0.62552 per GH/s.
That means the total network is paying out 8.4% better than expected.

Where you at?

Edit: This is where you are at in the last 24 hours:

In the past 24 hours Deepbit has found 18 blocks at 3177 GH/s, giving them a value of ⊅0.28328612 per gigahash.
In the past 24 hours P2Pool has found 5 blocks at 229 GH/s, giving them a value of ⊅1.09170305 per gigahash.

How much worse is p2pool now?

[rav3n_pl]

Maybe all our "troubles" are from badly coded luck chart?
