When changing the difficulty for one of my miners on Slushpool, how long will it take to come into effect? I have an S9 and am trying to decrease the bandwidth consumption. I understand if I increase the difficulty I should use less bandwidth because I will be submitting my shares and requesting work less frequently (am I right about this?).

Also, does anyone have any suggestions on how I can reduce my total bandwidth / traffic use if I have multiple (20+) S9's running on the same network? I will be using a cellular data plan, so it is important to minimize my data usage.

Thanks Smiley

I can't tell you about the difficulty settings as I have tried to change mine and have never gotten them set satisfactorily. So I just put them back at the minimum. Whatever vardif Slush talks about, I don't see it working or at least I'm not doing something right and there is almost no real information to make good judgement implementations - at least that's my take. Wink

As for reducing bandwidth for multiple miners, you may want to look into a proxy. I know Kano has one available for his pool and I would guess that Slush probably has one too. But I don't know how to implement it and really have no need as I'm only running 7 miners.
But I think a proxy is what you should look into.
Let us know what you find out. It could benefit others, myself included.

Good luck! Smiley

Transactions must be included in a block to be properly completed. When you send a transaction, it is broadcast to miners. Miners can then optionally include it in their next blocks. Miners will be more inclined to include your transaction if it has a transaction fee.

As wmabern suggested, a proxy will dramatically decrease your bandwidth. You can use ckpool (linux only) in ckproxy mode to put as many miners as you like to connect to one worker on your pool. The ckpool link is in my signature.

Any idea what's going at slushpool only 3 blocks found at 07-Feb-2015 with 171.7 PHS and no block for 12hours!

Is it bad bad luck or because the difficulty is higher or something is not right with the pool!

Thanks

Hi VentMine, you can set the minimum difficulty to 28 000 which should decrease the bandwidth consumption by half. Let us know if it helps.

Hi abonami, thanks for mining with us. Currently there is no reason to believe it is anything more than just a bad luck.
Therefore the best thing to do is to stay mining.

Yeah, that would be a mild way of saying it.  Tongue

It makes me wonder about the "quality" of hash pointed at the pool. But since we have no way of seeing what miners are hashing with what hash rate, we have no way of looking for any kind of pattern. Not that the pool members would be able to discover something "fishy", but at least with the additional information we would have a chance of spotting something out of the ordinary - if it was there.

--snip---

I had written a good bit more but decided it was probably best to keep my "mouth" shut. It would at least be nice to see what miner hits a block. But for some reason, I guess that it's for the best to keep that information confidential.

In the mean time, since there's no additional information to go by, I guess I'll stick with the company line: bad luck.  Tongue

I hope it turns around quickly.  Huh

Well after close to 10 hours we just found another block. Good luck is returning. Hurray! Shocked LOL

Hmm, not sure what to say about that as I'm not really an expert on how so called "low quality hash" can affect the pool. I suspect you're referring to botnets or deliberate sabotage or high latency miners or? I'm sure the pool admins can see aberrant behavior on the pool. They do mention in the FAQs that they actively look for botnet activity and other such low quality hash being pointed at the pool. I dunno, let's hope that is not the case. Without knowing more details or feedback from the pool admin(s) I'd say it was just plain simple probability - ie pool luck. Luckily Wink it has returned and the goddess of coin fortune has blessed us with a recent streak of high luck. *does a little dance* Smiley

You're most probably completely correct, of course. I just needed something to occupy my time while waiting for the next block. I like to think of it as my complaining jolted the wheels of fortune a little jarring the clogged up blocks loose!   Grin
Happy mining to you!!  Cheesy Cheesy

Hi Guys,

I have been running for 3 months with an S7 which ALWAYS shows a stable speed of 4700Gh (NEVER seen it lower)

BUT on Slushpool it ALWAYS averages about 4550Gh-4600Gh ??

I have the difficulty on Slush as standard 8....Would altering this make a difference ??

I also read some where that you can add 'details' to the 'Miner Configuration' to alter is difficulty at the miner, by adding +500/500 (for a dificulty of 500) or similar to adjust it there also ?

Ayone help

Thanks

An

Hi VentMine, you can set the minimum difficulty to 28 000 which should decrease the bandwidth consumption by half. Let us know if it helps.

Hi SlushPool, yes I've got it figured out now. At first I made a small change to the difficulty so I didn't notice a significant variance / bandwidth change. I've since moved it from difficulty 25,000 to 250,000 and it didn't take long to verify that it did indeed work wonders at reducing bandwidth. I'm now at diff 500,000 for my S9 (max difficulty) just to see how low a bandwidth I can get (without running my own proxy as CK mentioned above).

So my variance, as expected, has increased dramatically. Should I be worried about increased stale shares or anything that will reduce my average hashrate, considering I am working at a ridiculously high difficulty of 500,000? I'm imagining my S9 working on a difficult share for a while before it finally realizes the pool has a new block to work on (just want confirmation from a smart person).

Thanks

It doesn't work quite like that. The discards are reported mostly from your machine throwing away current work because it's received the signal from the pool that the block has changed and it has accepted the new work parameters.

Question is how much can we trust the pool own autodiff mechanism and do certain miners fail to work properly with this? When I check some S7s of mine they do seem to report appropriate difficulty - same for S9s.

OK gotcha, so difficulty will have 0 effect on long term average. Thanks

If you set the difficulty excessively high for the asic, you will decrease your bandwidth usage, but, there is a tipping point wherein you begin to see something known as VARIENCE, your hashrate may look lower than you expected then awhile later it will look really high, like an exaggerated roller coaster.

SlushPool,

Hypothetically speaking here, what is to stop your pool from artificially creating workers and the hash rate associated with them.  For instance, the pool has stayed at around 17,000-17,300+/- workers while the combined pool hashing power has gone up 10-20PH?  Would it be possible for a pool to artificially increase their ghost workers hashing rates up by 10-20PH?  Are ghost workers or artificial hash rates plausible? 

I do not know anything about the backend operations of a mining pool, just generally curious?  Is this something that could be done on other mining pools?  I love your pool, just a little worried about the huge increase in hashing power and not an increase in workers that I would assume would come with that big of a jump.

How can I be sure a pool is not doing some shady stuff or do I just have to believe the stats from the pool? 

Again, this is all hypothetical and I am just curious.  Some backend pool experts school me to some knowledge please.

Thank you Gentlemen!

I can't offer any technical answer to your question but I do believe doing something like this would be a horrendous business decision, Slush has built a great brand and this kind of thing would destroy it forever. I think you could take notes on Hashrate and block frequency + block reward and figure out yourself if anything seemed off. Probably easier ways of doing it too
