Hey, we're back!

Ha! no, just thought about it a bit more.

lol

Did you change that because the pool boss just showed up?

I think I found the bug that was causing the crash under some limited circumstances (which happened last night), so hopefully that shouldn't happen again. 

I also changed the way the watchdog behaves, though I'm not sure why that failed still.

Well, I'm not sure why the getwork server crashed.  The one miner that was still mining was one of mine at 400 MH/s on a test server. 

Yes, it's correct that the pool is on "pause" if it goes down like that.  Shares do not decay and we pick up where we left off.  There's suppose to be a watchdog that brings it back up if that happens, but apparently that didn't work and I am looking into why.  I am no pleased about that.

Some of the new double geo code must have been the cause, as that's the only change, but I can't imagine why that would be.  I am also investigating that.

Don't know about phoenix - check the thread. As for backup I'd use PPS or a PPS variant double-g scored pool.

If I understand correctly, you won't lose your rewards unless the pool comes back up again and everyone except you starts mining. This is because no (or in this case, very few) shares are being submitted. So the pool is kind of on "pause". I may be wrong, so someone please correct me if I am.

What kinda irks me is that some shares are still being submitted which is in fact eroding everyone elses rewards at the moment.


Is it possible to do this at all with phoenix? poclbm was too slow for me and so I stopped using it.  Also, any recommondations on a backup pool? I'd rather backup to a pool that won't let my shares decay after I leave them when Eclipse comes back online. lulz Oh, the hypocrisy!

scoring system is based on shares submitted not time elapsed so downtime won't have any effect on them.

I don't really understand these things so I'll probably get jumped on for saying...

I think we'll pick up where we left off...

unless we spend too much time mining elsewhere.

EMC has been down for over 5 hours now, so I guess under the new scoring system I loose all my rewards?

Use poclbm with backup pools. It'll go to a backup pool if the main one is down. If you used it you'd not be bothered if the pool was down, you'd just start mining elsewhere. Set and forget.

That's a waste of time and energy that could be used elsewhere in the meantime. The longer my miners sit idle, the potentially longer they may never pay themselves off. They need to be crunching 99.9% of the time 24/7

Uh, leave your miner running?

Is there a method to notify us when the pool is back up again? Or do I have to keep checking the website? I would really prefer to not have my shares decay once the pool comes back up again.

Somebody wake up Inaba

dang it broke good 

Pool went down for a minute or two, then went down again. DDOS? Or pool and website updates?

Website now say "Could not connect: Too many connections".

Website back after 10 mins or so.  

Well, the tl;dr version is "For every share you submit, you will get on average exactly your fair reward, with lower variance than other methods."

Still techinical imo, hybrid between pps and pplns? what's this?, If thats for the website you will have to make it more simple and treat them like they are completely new, assume they dont know any other payment method and just sell your own.

ran it by my friend and he actually tried but concluded with tl;dr.

A word about the new Double Geomtric Scoring (DGS) system:

EMC will be moving from the Geometric Scoring system to the Double Geomtric Scoring system.  Twice the GEOMETRIES!  ZOMG!!11!1one!!

But seriously the new system will be somewhat different than the old system, and perhaps a bit unfamiliar to some people, so want to go over some of the major points and answer any questions people might have.

First off, this system is a hybrid between the current geometric system and the PPLNS system.  In our current system, your shares geometrically decay, becoming worthless after a period of time (in our case, about 5 hours) - if you stop mining, after ~5 hours you will no longer receive a reward.  This has the advantage of making the pool hopper proof, but the disadvantage that there would be a chance you would not be paid due to your shares decaying.

With the DGS, your shares decay much more gradually, over not only the number of shares but also the number of blocks. What this means is that there is effectively a sliding window of time where you will be paid for shares submitted.  Each share submitted is paid a score which will eventually be converted into BTC but over time (shares AND blocks), the score decays.  This happens at a much slower rate than with the geometric system, thus reducing variance on a per share basis and spreading your score decay over several blocks.  A consistent miner will eventually reach a point where your hashrate is in proportion to the pool and your payout will be the same as an unhopped proportional pool on a per block basis.  If you are inconsistent, your payout will also be inconsistent - however, you will always eventually be paid for the work you've done regardless of when or how consistently you have submitted that work, until your score decays past the point of value.

To be a little more technical, your score is an estimated average pending reward.  When a block is found, some of your score is converted into BTC up to the total amount of BTC generated (50 BTC basically), once everyone has been paid evenly up to 50 BTC amount, the rest of your score is stored going into the next round and the process will happen again.  On really long rounds, this means that the pool will pay out a bit of extra from it's own pocket to pay off everyone who contributed and on short rounds the BTC will be stored for future unluck rounds.

This method is completely hopping proof, so there will be no losses to pool hoppers.  You can jump in and out of the pool and expect to be paid fairly for what you've contributed, like a PPS pool.  The variance is much lower than the geometric method and similar to proportional while the maturity time is much shorter than the *SMPPS methods.  Because the risk to the pool is greatly reduced, we also are not forced to charge exorbitant fees to hedge future losses on long rounds.

For a more technical explanation of the system, you can see this thread: https://bitcointalksearch.org/topic/double-geometric-method-hopping-proof-low-variance-reward-system-39497

I welcome any questions or comments you all have in regards to this new system.  I plan on making it live within the next block or two, after I have verified that it is paying out properly vs the current system. Currently it is running in tandem with the geometric scoring so that I can verify the output and payout.
