Altcoin.pw P2Pool

As of 5/4/2013, the pool is going to be shut down due to a DDoS attack. My provider can't handle it. Sorry guys, I guess someone doesn't like the CNC. Find another pool.

CNC Tips: CVQM7VKF4Bi4sVg2ScCGcWTaUzyzQvvYKL

Thumbs UP! :)

Restarting it really quick.
Done.

Wierd, shares are getting accepted but no payout. Same with all the pools i have tried.  :-\

Payout takes time. It's the way P2Pool works. First the pool has to find a "Share", then P2Pool has to find a block.

Expected time to share: 0.361 hours

Okey. I mined for 16 hours today tho with 2Mhash/s. Tryed 3 different pools but i have only gotten 100 ish coins, and those I got within the first 10 minutes of today. After that I havent recived anything :/

Orphan rates are high due to the low difficulty. That's probably the reason you got so little.

If it makes you feel any better, I had over 45 orphans when I got home and only 1 accepted block. That was with solo mining.

Still nothing, maybe i need to use cgminer instead of guiminer for it to work? My payment adress is not listed on the site atm.

If you don't show up as one of the many miners on the Graphs Page (http://altcoin.pw:1024/static/graphs.html?Day), then something is wrong.

Added a guide to the OP about lower difficulty shares. Smaller miners may find that useful.

Removing the fee. Going down for about 15 seconds.

Pool is back up. Fee is removed.

I am mining since almost 30 minutes and I am not in the list.
Does it take a while to be in it ? or is there any problem ?

I see.. Nice of you to remove the fee.

Is it better for a pool to have many workers or few workers and lower hashrate? How will that affect each individual's reward?

So many little 1.5 CHN transactions coming from you lol

Take a look at the OP. Yes, it depends on how fast you find a P2Pool share (not regular share). The difficulty of the actual P2Pool share is 0.498 right now.

After you find your first accepted P2Pool share you will pop up on the list.

Don't worry though, you aren't loosing anything. Keep tugging along until you get lucky.

That's how P2Pool works.

I have at least 115 accepted..
Is it because I use the +0.00025 ?

You'll make less per block on a pool with a higher hashrate, but in turn there will be more blocks.

A pool with a smaller hashrate will find blocks less often, but you will get a bigger chunk.

Eventually, either will even out. You will make no more on a small pool then a big pool.

Doesn't matter. Those are lower difficulty shares. You'll have to wait until you get a share equal to or over the P2Pool difficulty. Doesn't matter if you mine with +0.00025 or without, it makes no difference.

Yeah that's how I figured it'd work out. Hopefully with my 4 MH/s at this pool I'll get bigger payouts per block now lol

Where can we contact the developers of ChinaCoin ? We need to motivate them to promote it, translate their damn website, rebrand logo, etc.

Sorry for that restart, I had to fix a small problem.

Upgraded P2Pool to the latest commit. Your stats on the website were probably reset, but because there are still other nodes on the older version you will receive all the CNC you mined.

I have 3 rigs mining, they are all showing good hash rates but one is showing very low to no shares being accepted. Any ideas?

The pool is working great. Just keep it like this =)
It's the best one so far.

Try restarting it. I should have just fixed that problem.

Thanks! The update just fixed quite a few bugs regarding share difficulty.

Don't know about the update. But it's been going great since I started. Now it's dying down a bit but still receiving some small payments :)

You should start seeing much less tiny 1-3 coin transactions. You will now see 8-30 coin transactions instead, but much less often. This should help relieve high transaction fees.

Edit: Keyword is should, I don't have any idea what the changes will actually do. Now I'm getting half coins. :D

Can this pool be ran with a no-longpoll option?

Why would you want to disable longpoll?

I have a CPU that does 10 k/hash/sec.

I just thought that I'd get some shares if I disabled longpoll.. :)

Disabling longpoll won't help you get shares. Even if you did get a share, without longpoll it would more then likely be stale/orphaned.

I started getting larger transactions like 18, 22 but it fell back to the smaller ones now.

I'm not getting anything now anymore... :(

That was because you were getting transactions from two separate versions. One with the small transactions, and one with the big ones.

Update: I downgraded back to the old version with the small transactions. The latest version had stales that were too high for my tastes.

Yeeesss... Yeeessss... Good Good.. The old version gave me like 1000 CHN in 30 minutes ^_^
Which is nice...

Bob's pool barely gave me that in 3 hours...

EDIT: is adding+0.00025 to the end of the CHN address more effective for lower hashrates like I've got with that CPU computer I'm using with 10 k/hash/sec ?

I think you just got really lucky earlier, the version had nothing to do with it.

Been mining for over 2 hours with the lower difficulty. Over 200 shares but no payout yet :(

!!! Someone mining either screwed up their address or didn't set one! You will not receive coins by doing that, you are basically donating to me. !!!

Double check your miners if you think this is you.

I have multiple 650 k/h cards at your pool.  Is it better to be at the smaller share size?  I was at the larger share size buy most blocks I didn't even submit a single share.

Even if you are mining with the lower difficulty, you are still just waiting until you get to the P2Pool difficulty. You won't recieve anything until you find a P2Pool share. Keep mining, it is just luck. Once you find one, you will be paid a consistent amount for a total of 120 P2Pool shares (I think that is what the PPLNS is set to).

What if we don't get 120 shares and stop mining after having just 10-20 shares. Will we still get the reward?

High difficulty and low difficulty really make no difference since you don't make anything until you mine a high difficulty share anyway. Your shares aren't consistently what you set it to, you just set the minimum that you want to generate.

In the end, it makes zero difference. I'd just leave it.

Is there a time limit?

Sadly, I do not think so. If you really want to stop you should wait for your next P2Pool share, then stop right after.

What do you mean?

I'm not 100% sure on how P2Pool works, It's been a long time since I've used it. From my knowledge all shares are pooled, and for every share you mine you will get a slice of a block until your share expires from said share pool. Looking at the code I think that share pool is 120 shares in size.

I'm talking about P2Pool shares, not low difficulty shares. (Again, I think)

Cheers

Wait a minute, this is only for +0.0025 setting right?

The best way I can explain it is with an example.
https://i.imgur.com/b8EINRI.png

Notice how none of those shares are actually difficulty 16.

Even if you are sending more shares, you won't actually make anything until you get a share that is equal to or higher then P2Pool's difficulty. That share in the middle over a thousand was one I think.

You aren't loosing anything though, don't misunderstand.


Lets say it took you an hour, but you finally got a P2Pool share. It wouldn't have mattered if your difficulty was 16, or set by the pool, because you still had a share worth enough to be a P2Pool share. The setting basically tells cgminer "Don't send any shares lower then this difficulty".


It's hard to explain, if you read up on the bitcoin wiki about how shares and pools work you may understand better. The point is, wait until you start receiving money in your wallet before you stop mining.

And I sort of forgot to answer your question straight out. Yes, that statement was only for those using smaller shares.

If you are using +0.00025 you should wait until you see transactions coming into your wallet before you stop mining, because that means one of your shares was a high enough difficulty to be accepted.

If you aren't using +0.00025 you should stop mining as soon as you get a single share, because that means you mined a P2Pool share.

Will the transactions ever get higher? I'm sending 550kh/s and only getting 0.3473112 CNC per payout.

Was getting 2-8CNC earlier with different pool.

Well, the difficulty went up about an hour ago. Meaning you will make 4 times less money than before.

And with the other pool you might have gotten 3-8 CNC but it was less often so all in all, about the same really..

Throwing around 17,500 KH at it overnight...for the heck of it. We'll see how this goes. :)

https://i.imgur.com/mCOAIEp.png

That's nothing I can't handle. ;)

Just keep the pool going, it's going great. Don't stop it for any reason :P

Bob's second pool I was getting 2-8 CNC I was getting the transactions every minute or 2

Here I'm getting them every minute or 2 as well just SIGNIFICANTLY less.. so all-in-all no where near the same.

Yeah, I stopped getting CHNCoins too... kinda sucks tbh!

:-S

Do bob's pool still work?

It depends on luck. There is a high variance with P2Pool. Sometimes you will make more, sometimes you will make less. Over time it evens out to what you should make depending on your hashrate. Switching pools doesn't change luck. :P

Some people can't take variance though, it's understandable.

The difficulty is 1 now as well, it is 4 times less profitable to mine.

Variance would be nice.. This is what I'm getting https://i.imgur.com/nspGNZm.png

The EXACT same transaction over and over and over not a single number change anywhere.

Do I show up? - CWwB3nYYkkseLo8TyyNJJr9pqHA49G9KWQ

Been pumping shares your way.

same here...i was at passion node and payout stopped altogether, so I switched here.  I am averaging about 1.5 CHN per minute. And I couldn't tell if the payout changed on passion's pool because of difficulty retarget or if there was an issue with the pool. But I'm happy with how things are going so far with this pool.  And just an fyi, your website's front page is still showing diff at 0.54, or is that effective diff? 

What is your hashrate?

1.5 m/hash/sec something?

How often to you get paid? I have been at it for a while now and haven't received anything. Is my hash rate (100 khash/s) just too low to generate anything?

You won't make much with that. I'm averaging one payment/minute.

I was getting paid every two minutes for a while .8 each time usually. It's now stopped even though my miners are chugging along fine. What's going on? Haven't had a payout in 20 minutes. I forgot to mention. My address appears in the graph section, but no longer am i among the miners. I was there a couple hours ago.. I'm pretty confused.

This pool gave me 70% stales...

use this 1 instead

http://pool.dillavouws.com/stats

I'm only getting 5% stales and payout is consistent so staying put for awhile.

Did you restart your miners? Send the op a PM.

Restarted miners. Still showing up, and updating on the graph page. No payouts and not on the miner page anymore. Sent pm but he's offline.

Same here ...seems payouts have halted and shares accepted even after restarting miners.  I'll give it 15 more minutes before I switch.

I have mined for 5 hours with 110kh/s and got 13 shares, but till now no payment for me.
Is it right?

I am not sure.  Maybe check your address.  You can also post your address in this forum and he can check if your miner is showing up.

Yeah, my miners aren't showing up on the miner list anymore either.  Very strange.

Guys, that is how P2Pool works. You only find a P2Pool difficulty share every once in awhile, and when you do, you get paid for awhile. When you disappear off the mining page that means that your payment run is over and you need to mine more before you will appear there again.


For smaller miners, it will take up to 1-4 hours depending on how lucky you are (variance) before you appear on the site again.

https://i.imgur.com/3oEgA7i.png

Look at that gap. I only have 200kh/s, and it took me over an hour to find a P2Pool block. Don't worry! That is normal. You will still be paid what you earned.

Awesome, thanks for clarification.

Glad to see it kept running throughout the night.

Someone is still mining with the incorrect settings. Whoever it is, you are basically donating to me. You should really make sure your miner is setup up right.

Is it normal that my address doesn't show up in the miners list? http://altcoin.pw:1024/static/mine.html

my CNC address: CPzXY82jtQVGDXvwSA4SRvEVXvq7bt3f66

Is this normal? After running for 30 minutes I have 5, 3, 10 & 6 shares accepted. 4X 7950 rig.

so i ran through the night, my address shows up in the pool fine. however my wallet still is updating so i cant see any transactions.

in any case it seems like i have a fairly low number of shares...

715 accepted, 174 rejected

i notice in cgminer i see this line 90% of the time:


should i modify my settings or is this looking okay?  i am getting 2.5MH/s and im worried ive only mined a few coins in comparison to what i should have mined!

Your p2pool node is working great for me, just wanted to say thanks. After setting my own up locally and on my server, I give up on trying to get blocks without rejects. You've cracked the problem it seems, all my shares are being paid via your pool nearly as fast as I can mine them.

How are you checking to see if you're getting paid?  Your wallet?  If so how long did it take for your wallet to sync?  Mine's been syncing for 9 hours and still isn't even remotely close.

Yes. Those are high difficulty P2Pool shares. The small shares people are talking about in this thread are much lower difficulty.

Ok, I'm at 2.79 per payout with about 7.5 mhash. I checked a couple addresses above me and they were making close to double with same or less mhash. Also, when I click through on my address it says address not seen on the network, is that normal?

It is just variance, so it will even out. And the address thing, its because the links lead to a litecoin block explorer. This isn't litecoin, therefore the address doesn't exist on the site.

It seems like it is much easier to mine now that the difficulty rose to 4, so I may update once again to the latest commit since stales will be much lower now. No more tiny payments. Sometime later probably.

Are you restarting now?

Since the pool crashed I decided to apply the commit again. Lets see if it does well this time. If it doesn't, I think we have a high enough hashrate that I can apply my own fixes. The downside to my own fixes is that we will be a single node, not connected to other ones.

Should I switch pools/will I be paid for my work thus far?

What do you mean by a "commit"

Github.


I'm having a few issues, hold on.

Having major problems since that crash. Every single miner who was still pointed at the pool kept generating shares for the dead pool. Now P2Pool is using up an entire cpu because hundreds of stale shares are being sent at it at once.

Speak english. I got a buy order to fill...

The pool is down and I just fixed it. The new port is 2048.

any input is appreciated. again i do appreciate your hard work!

getting tons of stales on the new port

Pool is updated.

Changes:
- Fixed memory leak.
- P2Pool difficulty shares should be easier to find for small miners. <---- Not 100% sure I fixed this issue.
- WE ARE NOW A SINGLE NODE. No longer are we part of P2Pool. Our hashrate is large enough to be a single node.
- Payments will be far fewer then before, but they should be bigger sums. <---- Not 100% sure.

They'll fix themselves, give it a few minutes.

Is there a reason why the shares are at 15 difficulty by default now?

Just applied another fix:

Stales should be greatly reduced. I increased the share time from 15 to 45 seconds. This may take some time before it becomes noticeable.

Just to confirm port went from 1024 to 2048?

Yes. Too many miners were sending waaaay overstale shares to 1024. It was overloading P2Pool.

I guess it wasn't made to handle these many clients.

Sorry define "overstale shares"?

nice one!

The stale shares were 30+ minutes old.

Seems to be working fine, good job

Yup working here too, thanks Tittiez (always wanted to say that)

You might want to update the original post with the new port?

Thanks, done.

Believe it or not, I didn't actually increase or decrease stales.
I just changed it to accept shares up to 45 seconds late instead of 15 seconds late.
Really, we are probably all mining about 30-40% stales right now, but so is EVERY OTHER POOL.
So really, we aren't loosing anything!

Does that make any sense? :P

I just did it so people will stop bitching about stales, something every other pool has a problem with right now due to the low difficulty.

I'm hishashing away but not seeing any flow of CNC.

@Liberty
http://altcoin.pw:2048/static/mine.html

We are mining with about 6.5MH/s right now as a pool. It will take longer to find a block until more miners switch over. The good thing about this though is that the payout is higher for us.

No blocks found yet since the port got changed, am I reading the 'Blocks' page right?

Yes you are. The pool has been unlucky. :-[

Just thought I'd check!    :D

We wouldn't have this problem if the miners came back. We've been at 10MH/s for the last hour or two.

.... then 2 out of the next 3 blocks   ;D

Much Better! :D

the next port are very good . I got less rejected . Just put 10Mh in your pool . Good job . Respect :)

I'm not getting any shares...

I just put inside some big guns ... Let's find those blocks ...

Joining... Lets get there a lot seem to be having trouble finding block already

Im sorry for a possible noob question, but can you let me know I'f im doing this ok?

https://i.imgur.com/SjqBdGr.png  this is my stats. Any other coin  this thrives. The hash is there, but the Ultility rate is basically non existent, and the progress seems overall just very slow. Granted it's only been mining for 10 mins or so, I understand I wont see payment quickly. But  I'm seeing 35 shares, with 5 rejected. 2.71 utility, and 60% Efficentcy,

On every other coin, LTC and FTC specifically. I'm looking at 100+ Utility, and over 9,000% Efficenticy. And the Accept/Reject display is moving a mile a minute, and my shares skyrocket every second.

Again, I just wanna make sure Im doing this correct, I used the values you provided and I'm about to go to bed now. I'll be up in 3 hours for work, so hope to hear a reply soon to fix any problems (If there is some) before I go into work so I can dump all my rigs into this before I leave :D

Thanks!!

I've been busily mining on this pool (with my modest setup)... working great, thanks Tittiez!

Anyone got ideas for converting these CNC into LTC?  Are there any exchanges up yet?

I've put a WTT post up, but no takers yet.

Thanks!

Difficulty rises as more people join the pool. It's normal for you to see less shares.

You are better off trading with someone here on the forums.

fix your web and your pool plz. The web cant connect and the pool seem dont accept the shares....

Yep! You are down buddy!

Switching to backup pool....

I'm not home right now. I'll see what I can do.

I think I got it.

Saved by my phone.

Seeing this message:

Warning: LOST CONTACT WITH BITCOIND for 10.1 minutes! Check that it isn't frozen or dead!

I keep getting the message:

Stratum from pool 0 requested work restart

I this normal?  I am accepting a couple of shares but this message keeps popping up as well.  Just want to make sure this is normal and i am not wasting my time.

Thanks

Yep totally normal.

Did the pool just go down?

Looks like it had a small hiccup, back up for me.

I can get to the pool page , but my client still has not been able to stay connected for long

not responding...

Yeah went back up for a sec for me but definitely back down now.

My VPS provider suspended my server because they believed it was under a DDoS attack because I had so many IP addresses connected to me. I sent a ticket in.

Or, possibly, it actually was under attack. I don't believe it was though.

My VPS provider said it was an attack, and looking at the logs he is right. Sorry guys, I can't keep this running if people are going to ddos it.

chncoin.no-ip.biz says he's being DDos'ed too

So are you going to help me setup my p2pool ? I've sent you a PM. It's not really nice to hoard :D

seems to be the theme for this coin. /sigh

Seriously, I can setup a ddos proof mining pool... only if you people would actually help us, lower skilled ppl to do it.

Tittiez :(

What do you need help with?

PM

please don't say we're to use blastbobs incredibly unstable pools or go solo :(

My pool is running, yet to be DOSed I guess....

You could use my pool... If I could actually find a good git source and set it up =) I have the perfect low latency server for it.

I must have made someone mad, because I'm still getting hit with a ddos. I mean, I shut down the pool. I was planning to eventually anyway, I can't keep it up forever. It must be something personal?
