Topic: [POOL][Scrypt][Scrypt-N][X11] Profit switching pool - wafflepool.com - page 275. (Read 465567 times)

I have no real reason not to remove any, but it seems like a large percentage of coins to remove at once. Why not remove the "extremely" now, then give it a week or two before removing the "very".

Just restarted with h=128 on uswest. Will probably test 256 and p=128/256 over the coming days depending on reject %.

Thanks for the updates!

Personally I'm fine with these choices, but I've seen a few people giving reasons for keeping LTC in the equation.  It's never the most profitable, but it tends to stay at its middling profitability even when everything else drops, so on dismal days (like last weekend) it might be the lesser of two evils.  That's its only use I can see though - as a fallback. 

Sorry for posting multiple in a row, just a decent number of things happening at a time, and don't want to keep you guys in the dark

Later tonight (6hrs from now or so) we'll start removing some coins (see previous post for reasons: https://bitcointalksearch.org/topic/m.4976961).

The expected coins to be removed, unless someone has a good reason not to (please post!):
Coin, Removal Likeliness, Reason:
Fastcoin, extremely, block times are too fast to do with any latency whatsoever - pooling pretty much kills it.
Galaxycoin, extremely, hasn't been profitable since Jan 5th, diff retarget way too fast to actually switch to it...
Hobonickles, extremely, fast block times, rarely profitably by more than a slight margin when it is, daemon is very heavy (huge blockchain)
Emerald, extremely, very fast block times (20s), difficult to pool mine...
Bitbar, very, hasn't been profitable since Jan 15th
Casinocoin, very, fast block times (30s) and highest orphan rate that we have (12%)
Feathercoin, very, hasn't ever been profitable (since pool up) - unlikely to change
Worldcoin, moderate, fast block times (30s) and 2nd highest orphan rate (10%)
Litecoin, moderate, hasn't ever been profitable (since pool up) - unlikely to change, can add back if it does

Comments?  Reasons I shouldn't remove any of these?

Just updated my worker with the new h= data, and eu server. So good it looks fine.

Definitely think it has something to do with coin switches at the same time as diff switches (during the grace period).

That said, 2 new password features have been added and spooled up on NEW endpoints (not on old endpoints, they're being phased out in a day or so).

On the new endpoints (useast, uswest, eu), you can now set your password as "d=XXX" or "h=XXX".

XXX being the difficulty you'd like to use.  In the case of "d=" it is a hardcoded value, and your difficulty should never change (hard-locked difficulty), in the case of "h=" it is given as a HINT, instead of starting at the server default on start (16), you'll start at the XXX, but still use vardiff.  "h=" uses vardiff, "d=" does not.

Valid values for XXX are 64, 128, 256, 512, 1024.  Don't want to add lower to avoid flooding with tons of low difficulty shares.

A good rule of thumb for difficulties (rough values) for mining speeds:
0kH-500kH: default
500kH-1MH: 64
1-2MH: 128
2-3MH: 256
3-5MH: 512
5+MH: 1024

Let me know if these are working for you guys.

Working on the new difficulty locking/hinting on the new endpoints as we speak (couple hours or so).

In the meantime, can someone seeing this issue ("share above target") restart a miner that normally has a reasonably high difficulty (128+), and try their best to get a log of what time the difficulty adjustment is requested, and what time it takes before the miner starts using the new work difficulty?

Should see something like:
xxx Accepted X/64
xxx Accepted X/64
xxx Accepted X/64
AAA Difficulty changed to 128
xxx Accepted X/64
xxx Accepted X/64
BBB Accepted X/128

I'm looking for the timestamps listed as "AAA" and "BBB" above (when we request a change, and when that change gets applied).  Also, in the same post, cgminer/bfgminer + version + command params (intensity, etc) would be super helpful

This is what I have in cgminer, EU endpoint ...

Ahh okay, didnt know that. Thanks.

The unexchanged amount there was bugged due to casinocoin, they were literally coins that didn't exist (I had a banner up at the top of the site for a while, a block got processed incorrectly, but has been fixed).

I've been making sure that everything that can be exchanged is exchanged before we actually do a payout.  A lot of the time the unexchanged amount is just delayed by exchanges. Takes X number of confirmations, and that network is slow, or the exchange is slow (looking at you cryptsy), or in the case of some coins (mooncoin specifically), it takes (I think) 50 or 60 confirmations for a block to mature (before we can exchange it), and at 4min per block, you're looking at close to a day and a half before we can convert (and theres really nothing we can do about it).  Essentially, if unconfirmed values miss a payout, they'll be in the next one...

I dont think its worth it, we are getting a nice btc per mhash atm, so i dont think its worth your time, or our hashing.


You didnt reply to my last question;

Wouldnt it be possible to make it so, before a payout, it converts the majority of the coins?  I missed a payout with 0.0005 because you moved the payout from 14:30 to 12:00, and had 0.007 unexchanged at the time.

Looking through the coinmarket thread/site, it doesn't look like they have any trade API available yet (point me in the right direction if I missed it).

Which brings up another question.  I'm OK (a bit hesitant) with adding those coins that have to be manually traded (only listed on exchanges without an automated api), but it is doable.  The problem with it is that I really wouldn't be able to trade them off more than once a day (lose too much working time constantly trading), which opens up a TON of market risk on those coins.  And since most of them (since they're not traded on larger exchanges) have low depth, the price change risk is a very real one.

How do you guys prefer to handle these?

Obviously varies by day, but our stats page has each of the last 14x24hr periods listed on a per-day, and on a rolling total basis.


Looking at it further (and hearing that its happening more on uswest rather than main), my guess is its an odd interaction between coin switches (which are a bit more aggressive on new endpoints) and vardiff switches.  Just guessing because I haven't personally seen it here as it happens, but guess is that if a vardiff switch happens, and you'd normally be given a grace period of 30 sec, and then a coin switch immediately happens, that it might not be respecting the grace period.  The vardiff d=xxx option in auth will help, so I'll try to get that out today, as it seems like the quickest fix.


A few others are in testing, but haven't been actively tested in the last few days since stuff has been coming up.  I was looking at coinmarket.io yesterday, but when I checked, they were down, and then turned into an email mailing list page.  I see they're up now, and I'll see what their API lets us do (see if it does everything we need).  I'd love to get a better exchange in than cryptsy, but every one that I've looked at either has really bad depth (poor prices), or doesn't have a realistic api (coinedup), or doesn't have a bunch of coins that we really need.  Long story short, on the list


Yep, these will be hard locked to a few allowed values (don't want someone passing d=1 with a 10MH/s rig), probably allowing 128, 256, 512, 1024 to be passed.  Working on it today, might see some quick cutovers on the new endpoints as they add the functionality.

Yes i think this too.
There are some altcoins more profitable, i think, than others added in the pool( kittehcoin for example? ), but we don't know if add a coin is so fast, and easy, as we can think.

PoolWaffle: when you implement the ability to specify starting vardiff in the password field, can you please make it a minimum value.  e.g. I say d=512, and that means my vardiff should never change (because max is also 512).  This would be rather ideal for larger miners, as vardiff is quite useless to me, and is just causing rejected shares on occasion.  Having a fixed diff also makes certain rig stats easier to calculate.

Also are you currently only using one exchange? I think the sooner we get more active the better. There are a fair few now, some are slower than others but  I'm sure users are willing to sacrifice an hour or so wait for better btc/mh. https://www.coinmarket.io/ is one such recent exchange.

The more new coins you add the better, I think that is what will set the best multipools out from the mediocre, ability to quickly adapt to maximise profit.

I'm at 2% rejects after restarting last night (uswest). Used to average less than one on the main server. As soon as the minimum vardiff option goes live I'll restart again and see what happens.

As far as profits vs middlecoin, it has been pretty similar. I'm waiting for the fix on the website, but if the numbers are accurate, my wafflepool hash is doing better than my middlecoin hash for the first time. I've been testing off and on, but tomorrow will be my 6th payout here.

I have consistently had comparable or better earnings from this pool.  Wafflepool has higher variance to some extent (one day a little lower, one day higher), but it has overall been a much better experience then middlecoin for me.  And when I ran side-by-side tests, I was pleased with the earnings here.


Looks like I spoke too soon.  Poolwaffle: something is borked here.

Hi Guys!

I have been reading the posts and the replys of the Operator of the pool.
I might say im impressed with his support on the questions and adding / fixing stuff to the pool.

I have currently a mini-farm pointed to MiddleCoin with a good success rate of earnings.
What can i expect if i move my operation to this pool?

How are the earnings currently?

I like this kind of support, and a much better and fair fee.

Thanks in advance...
