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

[jonnybravo0311]

Patience is required with p2pool - I am using less hashrate than you on a couple of different nodes, sometimes I can go without a share for 12 hours or more - then 2 or 3 shares will appear within 5 minutes of each other. Hash rate & diff is going up on every pool - this is the way of things.

Just sit tight - it'll come 

Difficulty going up... boy is that the truth.  I'm looking at 9.7M right now... any bets on when it crosses 10M?

How about the fact that the cgminer dev said should use at least 1 not zero?

M

Yeah, ck said he recommended a setting of 1 - that's why I used it to start with, but as you can see, setting it to 0 works better for my setup 

Can confirm that using --queue 0 on my S3's results in less DOA also    (also running a local node)

That's interesting data.  I'm actually using the default values of 4096 on my local node and get 1-2% DOA.  I never really noticed much difference when I set the queue values to 0 or 1 or left it alone at stock.

As the difficulty reaches 9M and touches 10M, I am switching back to Eligius.

I love the idea of P2Pool but with the difficulty increasing and me just having 1TH/s, I don't think it is very lucrative for me too keep mining on P2Pool.

At this point, P2Pool has basically become an altcoin with lower difficulty than Bitcoin that's immediately redeemable for BTC.

He has 1.5GH/s, take a look at the graph again.

i've look at the graph in this moment, but he has the same reward...

Yes but patience apart, I have mined for about 2 weeks and in the last 4-5 days my reward decrease and go to 0.

On http://p2pool.info/ the lowest active user speed is over 1900th/s

I believe that using --queue 0 puts more load on the asic cpu, but I'm not sure tbh - it might be the other way round - maybe ck can chime in here. Using a queue setting of zero has generally been regarded as the way to go with p2pool since the early days, although obviously the tech has changed since mining with 5 series GPU's 

Works good for me though.....

I know how you feel, I'm guessing your expected time to share is somewhere around 12 hours?

For me, if I was getting at least 1 share every 24 hours (and keeping ~3 in the active share chain) p2pool would still be worth it; the variance may be a bear and patience is very important, but I still believe p2pools payout will be higher over time then any other pool.

He has the same payout because he hasn't found another share, and his share is still on the chain.  If he doesn't find another share before that one falls off the chain, his payout will go to zero.  With the increasing difficulty, you're going to find fewer shares.  The theory is that the pool will find more blocks, meaning the fewer shares you find will be paid more often.

If it works for you, then have at it.  Personally, I saw no difference with the different queue settings.  To be honest, I have no idea why Bitmain sets the queue value so high, and to understand it would require having their driver code.  Bitmain uses an older version of cgminer that they have customized, so expectations of queue settings based upon the latest version of the software may not apply to Bitmain's fork.

No  share?

Look here

lol 


It must be remembered that he .

I believe there is something wrong with that node - according to the info bar on the left of the main page, the expected time to find a share is 49.4 days!!

If this is correct for a node that has 9GH/s, it's a seriously sick node - drop it immediately.

Nothing's wrong... the expected time to share for 9.01GH/s right now is:

Code:

Difficulty * 2^32 / hash rate / 86400
8538174.25 * 2^32 / 9010000000 / 86400 = 47.107 days

47.107 days.

[windpath]

47 days?! For a share? On a 9GH node?

One of my nodes is less than 2GH - expected time to share is 5.5 hours...........

I think your probably mixing up GH/s and TH/s At 2 TH/s you would be around 5 hours...

For Bitcoin?  The math doesn't work out that way.  Expected time to share is the formula I posted.  If you've got a Bitcoin p2pool node with only 2GH/s showing expected share time of 5.5 hours, something's wrong.  2GH/s expected time to share:

Code:

8076919.15 * 2^32 / 2000000000 / 86400 = 200.753 days

You should see a share every 200.753 days, not 5.5 hours.  I've got near 4TH/s mining on p2pool, and my expected time to share is about 2.5 hours.  No way should your 2GH/s be anywhere near that.

EDIT: Of course, you could be mixing up your "G" and your "T" .  He's got 9 Gigahash per second.  I presume you meant you have 2 Terrahash per second, in which case your expected time to share is 4.82 hours.

Ain't I the fool - I take it all back  

Must. Learn. To. Read.

Not used to seeing a node in Gh anymore........

hi wlz2011, care to share what is the secret behind?

Patience + love p2pool

I don't see how the part in bold can be anything other than belief.  How can p2pool payout more than Eligius?  Unless you have your own node and get merged mine blocks, Eligius with 0 donation comes out ahead of p2pool with 0 donation.

And when you throw in variance for small miners, you are likely to lose, possibly bigtime, as difficulty continues to increase.  Yes, it would even out in the end if difficulty remained the same, but it doesn't.

Well, it's a little more then belief, I have mined on every big pool that is publicly available, for me p2pool was the winner hands down.

Here seamaster is actually doing a side by side comparison with 6 ants on each p2pool, Eligius and BTCGuild (spoiler alert, p2pool is on top...):

https://bitcointalk.org/index.php?topic=416933.0

As I have a number of different mining hardware I decided to make some practical comparison of mining pools.

So I get two antMiners 180Gh each and pointed one of them to BTCGuild and other to p2pool node. Initial results of mining (180Gh) for period:
from 1 January till 14 January 2014: p2pool - BTC0.952269785 VS btcguild (PPS) - BTC0.77025336

Now is running continuous benchmark  6 antminers total 1080Gh on each pool:
14-31 Jan 2014:     p2pool - BTC2.99025045 VS btcguild (PPLNS) - BTC5.0158
1-14  Feb 2014:      p2pool - BTC3.2248 VS btcguild (PPLNS) - BTC2.7164 VS Eligius BTC2.5137
15-28  Feb 2014:    p2pool - BTC2.5711 VS btcguild (PPLNS) - BTC2.4763 VS Eligius BTC2.0456
1-14 March 2014:    p2pool - BTC1.1336 VS btcguild (PPLNS) - BTC1.7816 VS Eligius BTC1.7655
15-31 March 2014:  p2pool - BTC2.0796 VS btcguild (PPLNS) - BTC1.7523 VS Eligius BTC1.7838
1-14 April 2014:      p2pool - BTC1.0615 VS btcguild (PPLNS) - BTC1.1026 VS Eligius BTC1.2293
15-30 April 2014:     p2pool - BTC1.2836 VS btcguild (PPLNS) - BTC1.2097 VS Eligius BTC1.2339
1-14 May 2014:      p2pool - BTC0.7297 VS btcguild (PPLNS) - BTC0.7750 VS Eligius BTC1.0017
15-31 May 2014:     p2pool - BTC0.9148 VS btcguild (PPLNS) - BTC0.7351 VS Eligius BTC0.7290
1-14 June 2014:     p2pool - BTC0.4106 VS btcguild (PPLNS) - BTC0.5750 VS Eligius BTC0.5481
15-30 June 2014:   p2pool - BTC0.9081 VS btcguild (PPLNS) - BTC0.6732 VS Eligius BTC0.5135
1-14 July 2014:      p2pool - BTC0.6109 VS btcguild (PPLNS) - BTC0.3858 VS Eligius BTC0.4402


Total from 1 Feb 2014: p2pool - BTC14.9283 VS btcguild (PPLNS) - BTC14.183 VS Eligius BTC13.8043

Benchmark is goin on:
1080GH = 6 x AntMiners pointed to p2pool node
1080GH = 6 x antMiners to Eligius.st
1080GH = 6 x antMiners to btcguild

While I cant verify his numbers, I see no reason to not take them at face value...

[mdude77]

That could still be luck.  6 months ago 1 TH/s was HUGE.  Now, on p2pool, you're looking at 12 hours on avg for a share.

It also doesn't account for the NMC you get from Eligius, which you won't get from p2pool unless you have your own node and blocks are found.

But isn't the NMC you would get from Eligius barely anything?

It's all relative.  Wizkid advertises it as 105% PPS, so that should mean the NMC is 5% of what you get with BTC.

Overall, my point is there is nothing to explain why p2pool could come out ahead of any other pool with equal fees for the average user.  If you have a large enough hashrate for the variance to not be so bad, you'll come out even.  If you have a REALLY large hashrate you'll come out ahead if you use your own node because merged mining proceeds.  If you're a small miner, variance will likely hurt you.

Don't get me wrong.  I like p2pool.  I like the concept.  But statements like "you'll come out ahead with p2pool" I take issue with.

There are a few reasons p2pool might be better for a given miner then other pools, for example there is an edge for the miner who maintains a stale/DOA rate lower then the pool average.

But that really was not my point what I said (and you quoted) was "I still believe p2pools payout will be higher over time then any other pool." and I do believe that. You asked me to substantiate my belief and I did. As I stated, its my belief, I'm not claiming it to be a fact, and I certainly never said "you'll come out ahead with p2pool", your results may vary.

[PatMan]

Just a heads up - new S3 firmware is available.  Slight improvement & it's now possible to adjust the freq from the GUI.

Peace  

Oh, it breaks mdudes Antmon.........boooo!

Hi new to P2P,

A quick setup question:

1. I have downloaded bitcoin core 0.9.2.1
2. I have downloaded the whole blockchain (i.e. updated my bitcoin core)
3. I have downloaded p2pool win32_13.4
4. I setup the bitcoin.conf
5. I have runned the bitcoin and p2pool together

6...

Now I need to connect my miners to the pool, how?

forum says "http://HOST:9332/"
but then if my computer is behind router, how ?

is it "http://IP address:192.168.1.xx:9332" ?

[squashpile]

try 127.0.0.1:9332 for local machine or internal IP of local network node.
