We still need more miners!

WDC is at 125.47% profitability right now, come and join the fun!

Reduced fee to 0%

So far the beta has been going really really well.  No issues to speak of and for WDC we are getting a very low orphan rate.  Out of 43 blocks found only 2 were orphans.  I've seen reports of much higher orphan rates from other pools.  There may be some advantage in being on a smaller pool in this regard.

So far we've paid our beta miners two bonuses and more are coming.

Right now I am working on adding proper dynamic lastNshares calculation instead of using an arbitrary value.  This will have the result of shortening the ramp up and ramp down times for PPLNS and keeping them consistent even through difficulty changes.  Thanks to some excellent help from Meni Rosenfeld I have the necessary formula worked out and I just need to add it to the payout logic.

Just for comparison, at the current difficulty it will result in the ramp up and ramp down times being reduced by roughly 28% from what they are now.

the formula we are going to be using is 2 x (Block Difficulty / Share Difficulty).  Very few pools have this implemented correctly, most simply use an arbitrary value like us at the moment.  Not using a dynamic calculation means the results are pretty unpredictable.  It can take a very long time to reach your full payout if the value is too high or cause too much variance in payouts if the value is too low and the correct value needed changes depending on the Block Difficulty, which changes quite often as you know.

I plan to have this implemented this weekend.  We do still have plenty of server slots available, so if you are interested in helping us out go ahead and jump on the server!

Good work on this! Let us know how it goes. Some miner's don't seem to realize how PPLNS works and pool hop to quickly as a result. This should help.

That's part of the reason that I decided to implement this, and who can blame them for not understanding it ?  Most pools have a horribly broken PPLNS implementation, especially the ones based upon mmcFE because the default payout logic is also horribly flawed.  It's taken a tremendous amount of work (by many others as well as myself) to get it to the point where it is now but I  am getting very close to having a polished properly working base to build pools on, quickly and easily. 

In a related matter, I am planning on uploading the finished product to github or something like it so that others can use and continue to improve the source. 

Good to see.  I learned a while ago that leaving the lastnshares at the default is bad.

Dynamic lastNshares calculation is live!  I'll be watching it closely for the next few days to make sure it's working properly.

Also updated the left sidebar and the api to display the current lastNshares value and improved the descriptions and labels a little bit.

Also fixed a bug in the api and the left sidebar regarding the current round shares value.

Fixed the block stats graph to only display the last 15 blocks as that is all that will fit on a 15" LCD.

Fixed the zero variance line in the block stats graph to display the correct information.

Also, reduced the number of block details listed to 50 in the table.

Sent our BETA miners another bonus!

Took out the top 15 shares listing because it's mostly useless anyway and replaced it with the much more useful PPLNS status display which shows the current block payouts.

Also, updated the "Current Payout Est." display in the side bar to be MUCH more accurate.

I'm very pleased with the progress of the upgrades to the pool's front end.

Compared to a stock mmcFE install the main differences are :

Major Improvements to payout logic :
- No more missed Block Payouts (Silverwolf)
- No more overpaying some miners and underpaying others (Silverwolf)
- No more duplicated Block Payouts (Silverwolf)
- No more having two different and completely separate sets of code responsible for block payouts. (Silverwolf)
- Dynamic PPLNS lastNshares calculation 2 x (Block Diff / Share Diff) so PPLNS works the way it's supposed to.  (Silverwolf)
- Fast ramp/up and ramp/down of payouts so you don't have to wait forever to reach your full payout (See above line).(Silverwolf)
- PPLNS Status display (100% Transparency on block payouts, you can see exactly where the coins go) (Silverwolf)
- PPLNS lastNshares display in User Dashboard so you can see how many shares are currently being used to calculate payouts. (Silverwolf)
- Accurate Per Block Payout Estimates (Payout estimates are now generated by the same exact code as the actual payouts so no more inaccurate estimates) (Silverwolf)

Other Fixes & Improvents :
- Major Performance improvements (Charger)
- All Settings moved to a configuration.php file instead of being scattered throughout the code (Charger / Silverwolf)
- No more hardcoded values (Coin Name & Abbr, BlockValue, Confirmations Needed for payout, etc...) all of these have been moved to the configuration.php file. (Charger / Silverwolf)
- Corrected Dashboard Paid vs Unpaid & Current round shares display. (Silverwolf)
- Improved Dashboard item descriptions so they make sense (where applicable). (Silverwolf)
- Corrected ZeroVariance Line in Block Stats Chart to display the correct information. (Silverwolf)
- Orphan blocks are now displayed in the block list.

There is more, but I can't recall the rest at the moment.

 At the moment the PPLNS status display and payout estimates are 200 network blocks or about 50 minutes behind realtime due to an oversight on my part last night when implementing the new PPLNS system.

Going to make some tweaks tonight to fix it.  In the meantime, mine for at least an hour and you will appear on the PPLNS payout status.

Payouts will be properly credited, just about 50 minutes late... :(

Sorry about that.

Edit: FIXED

The issue with PPLNS data being 50 minutes behind has been fixed.  Also, the PPLNS Status display is now properly sorted.

Joined your pool, looks good so far! Need a few more miners.

The fix for the PPLNS delay caused an issue with the current round shares display.

This doesn't effect anything other than this display and I will fix it shortly.

edit : FIXED!

Glad to have you with us !

Fixed an issue with the current round shares display that was caused by the new upgrades to the PPLNS system.

Also, updated the dashboard a bit.

And upgraded the API to use the new accurate PPLNS payout estimates instead of the old half-assed calculation that was in there before.

Issued another bonus to our miners!

Also, just FYI the pool is entering the final phase of it's BETA status, won't be making many additional changes, mostly just fixing issues that crop up until the pool is stable enough that we remove the BETA designation.

Won't be long now... 

We still need more miners!  Give us a try would you ?

Thanks for the bonus!!

Your welcome !  ;D

Still looking for more miners!

Why don't you give us a try ?

Silver, just wanted to make sure if you haven't patched the pool, ask erundook about it. I think it was just an exploit for the stratum software that litecoin folk detected. Later :)

Also, looks like the pool distribution monitor is helping spread some hashes to you guys! Cool beans.

I patched the stratum server on 05/31/13, but thanks for making sure!

Still need more miners guys !

We have a Banner Add !

Our ad is running here : http://worldcoinsfaucet.info/

I'm not much of a graphic guy but I think it turned out pretty well. :)

We still have plenty of server slots available!

Give us a try !

The worldcoin pool is nearing shutdown due to lack of interest.

http://silverwolf.ath.cx/wdc

Doesn't anyone want to mine worldcoin anymore ?

I'm in, I love the 'PPLNS Status' window and 'PPLNS lastNshares' value. You have done very nice work !

Thank you!

It has been a lot of work and it's nice to hear that people appreciate it!

P.S. Tell your friends!  We need more miners!!!!

Finding blocks, but we still need more miners!

Hop on guys!

Silverwolf's Worldcoin (WDC) Pool!

* 0% Fee
* Accurate, Fast Payouts
* Stratum or Getwork

What Else is there ?

http://silverwolf.ath.cx/wdc (http://silverwolf.ath.cx/wdc)

Manual withdrawal functionality has been reworked to prevent exploitation and has been enabled again.

How it works now :

When you click the "Cash Out" button, instead of sending the money immediately it "Schedules" the withdrawal request.

Withdrawal requests are processed every minute when the cronjob runs.

Enjoy

Its closing down. So withdraw your WDCs now if you have still some left there.

All operating pools exiting BETA status as the code is working well and quite stable.

I'll leave it up as long as people are mining there.  There just isn't much interest at the moment.

Update: All the miners have quit mining on the WDC pool.  I will keep it open indefinitely in case someone wants to come back and mine.

Eventually I may pull it down completely, but as users still have balances I will not do so without at least a 7 day advance notice on this thread so that people have time to withdraw their coins.

I do hope people decide to come back and mine though, the pool's working perfectly.

Tweaked the DB to improve the performance of the stats page as it was getting a little sluggish.

We still have lots of open slots on the server !!

Increased share diff to 63 to match my other pools.

Restarted the stratum server to effect this change.

The hash rates on the pool will be wonky for a few minutes until it catches up with the change.

Thanks the1silverwolf, you are providing one rock solid pool !

Yep, this is my favorite WDC pool for sure.

Your welcome !

I'm glad you think so!

Tell your friends, we still have plenty of slots open.
