Special thanks to: TheSeven for getting stratum working :)

We will be offering early withdrawals after 20 block confirms (instead of 520) with a small additional fee. They will enabled once pool has enough reserves.

Been mining here for a while, earned 20 PPC with only 40 MH/s, lucky pool I should say :P Everything works nicely except for the long rounds, but nothing a decent hashrate can't fix.

oh and good job implementing Stratum to PPC! :D

Thanks for feedback!

We're glad you liked it :)

Finally... a Stratum PPC pool!!
Count me in!!   ;D

Added worker performance graphs!

Update:

• Added twitter news feed https://twitter.com/D7Pool
• Added pool hashrate chart
• Fixed worker performance charts

cgminer says the pool is dead

What version cgminer are you using?
Try pinging stratum.d7.lt

2.11.3

Ping responds fine. Just checked again and it's working now!

Love this pool wish others would join in.

Nice to hear that you got it working :)

Most people are now pumping other cryptos as ppcoin difficulty was driven very high by asics. Once it stabilises people will come back  :P

Time to pump some GH/s into this place enjoy seems my TRC pool is acting up maybe you should add TRC to mine on too :)

How long does it take for retarget? What are the difficulty intervals?

Unlike bitcoin, ppcoin difficulty adjustment is continuous. It adjusts difficulty on each block.
In the last 4 days difficulty dropped from 310k to current 243k

Update:

• Implemented minimum difficulty!

We have reached 10 GH/s!

Added shoutbox to the website! You can ask for help there :)

Do you have any intention to add TRC too ?

We might add other coin pools but we firstly need to make sure that ppcoin pool runs stable enough ;)

We have hit 600 GH/s and 100 active users :o

Updates:

• Changed N to diff * 1.25
• Adjusted hashrate calculations

oh there is a god, the place i was looking for since 12% on another pool.

Got sick of Coinotron so dropping in here. All seems good, can access website no issues and GPUs are mining away happily in no time.

You can say it...  Steal-o-tron...  That also happen to require 520 confirms if you want 2% fee (that's like half a week...)

I just tried this new pool...  Looks very polished.  I have 5 workers and no problem so far :)

THANK YOU! Been mining at coinotron, but others have eluded to the high fees/long confirmations there. In addition, my miner would drop out every few minutes for a few seconds. With this stratum enabled pool, I don't see the drop outs any more.

Thanks for positive feedback :)

As we know ppcoin requires a 520 confirmations which is a drawback for PPLNS pool. So we decided to allow withdrawals after 10 confirmations for those who are in an immediate need of funds. Since this involves risk for us the fee is 5% :)

Love your pool. Easy to change the shares difficulty.

Update:

• Added port 80 stratum mining on stratum.d7.lt:80
• Added getwork proxy on stratum.d7.lt:8080

I'm a-little confused over your PPLNS, is it if I stop mining and the total number of shares to complete the block passes Difficulty * 1.25, anything I did before that is unpaid? I only ask as shares I had in block 44278 dont show in recent blocks even tho i had some accepted before powering off for bed

Block 44278 was quite unlucky and shares submited that round exceeded N limit almost two times. Round started 2013-04-22 00:40:55 UTC and ended 2013-04-22 11:04:35 UTC so if you mined just before round started all shares have been likely discarded by the N limit.

Thanks for the great pool, guys :) I think you're the only decent PPCoin pool around.

Updates:

• Verified SSL!
• User specific timezone selection.

D7 is my fav pool when I mine for PPC, what I really like is the fact that I can choose the minimum difficulty of the requested shares.

Please, put more graphs for the graph junkies among us  ;D

great pool but the round confirmations is just waaaay too long for me...i don't know if that's something that be improved... it takes like several days..

Well, that is PPCoin thing. It requires 520 confirmations for block which is 2-4 days on average.

For those who are very anxious to get their coins we have early withdrawal feature. But since it involves risk for us there is a fee.

Love the pool chemicstry, it's been running well. Thanks for all the work you do!

Great pool, wish iit had graphs and more security when it comes to withdrawals or changing addresses.

If you want an unchangeable withdrawal address, you can use my pool  ;)

Holy crap, D7 is about 60% of the whole network right now :)

Is the pool under attack or down right now?

Looks DB related  :-\

Pool is back online ...  awaiting any info on what caused the outage 

ill start working here too  ;D

We had problems with server connectivity. Everything is online now :)

We always report issues and their resolving progress on https://twitter.com/D7Pool

Perhaps you could help me out as I'm having difficulty registering. Every username I input a username, even if it is me randomly smashing the keyboard returns, "Username is already in use."

nice pool, thnx

Hashrate is through the roof now, over 1TH/s!

Server down?

port 3333 seems to be offline

now both port 8080 and 3333 is offline.  :-[

Pool is offline again:

Jul 28: Recent power outage in the pools server room was the cause of the downtime. We are sorry for such an extended delay.


We are also working on a new open source high performance poolserver written in C++

Source: https://github.com/Intel/poolserver

Currently it is just bare bones, writing all libraries.
CMake is used for this project. Based on Boost libs.

Planned features:

• Speed. This is what C++ is for.
• Cross platform (Mainly Linux, Windows and MacOS)
  
• Multi database support (MySQL is 80% implemented with multithreading)
• Stratum (Maybe getwork too? Or separate proxy?)
• Statistics Daemon (Including different payment types)
• *Maybe* Frontend (php + caching)

If anyone is interested in collaborating pm me on here/github/skype.

Hello

Just set-up an account.

Pool looks good.

Mining now for few days. Pool is nice, although I have problem with Dynamic Diff.

It makes USB Block Erupters pretty much useless. I must restart miner frequently if I want to keep 8 Diff which is more than enough for my setup barely scrapping past 10Gh.

Blast! Pool switched now diff to 20!!! And I thought that switching to 12/13/14 was bad. That is less than 100 shares /BE daily. If this persist I really must return to BTC-Guild.

Pool Down : http://ppcoin.d7.lt/. My miners stopped mining at 12:24 PM New York time.

My browser says: Failed to connect to MySQL: (2003) Can't connect to MySQL server on '84.240.24.209' (110) when I try to open up the website.

Is it known?

My miners are still working on the pool.
latest stats: "height":71507,"timestamp":1380251527,"value":255.34,"finder":"tintinz","difficulty":2351765.06315,"confirms":18,"n":2939815

I just started mining on this pool, and the vardiff seems weird, jumping all over the place and doesn't seem to respect my minimum diff setting.

I'm running bfgminer 3.3.0 with two jallys and six usb block erupters, total 17 GH.  I set my minimum diff at 8 but the difficulty seems to jump rapidly from 1 to 5 to 25 to 125 to 625 and back down to 1 again.  With the sudden diff changes, I get a lot of rejects but shares seem to still be counted well.

Is there anything I need to do on my end to stabilize the diff changes?

hi, i'm interested to mine PPcoin,
Where can i find help to config my blade asic miner?
I test a lot of configuration but no one work.
Thanks,

loving the new android app, kudos

Pool & website seem down.

It's running fine. How are you connecting?

Website came back up for me about an hour later.

I've continually had problems connecting via stratum however, as have many of us on the pool.

Website been down for about 20 hrs for me again, in U.S. Still able to mine to us.d7.lt fine though.

Is D7 down right now? It appears to be

What's going on guys?

I posted a ticket with regards to a password reset over 2 weeks ago and you have still to acknowledge my request.

You claim to reply to all requests within 48 hours, but that is not true.

I cannot ask for a reset using my wallet address because I have not yet created a wallet address for my account.

Why the delay?

Does they admin still exist  :P

First pool I mined Peercoin on. Sad to see it go. Thanks for the years of service!
