1  Bitcoin / Pools / Re: [40+ PH] SlushPool (slushpool.com); World's First Mining Pool on: March 19, 2016, 10:10:06 PM
Something similar happened early last year if you look back once the hash rate went above a certain threshold blocks started taking forever.

The interesting part was people started to get fed up, so they started mining elsewhere and the hash rate dropped off substantially, then blocks started coming left and right. I even dug out some old Block Erupter cubes at the time and set them up. Obviously this was short lived then things reached a middle ground and now it seems we're right back at that point.

and three in a row just that quickly. Variance is a lovely name for a woman as well Smiley

And another 4 after that.

Quite a lot of miners do not know what variance is. They pick the biggest pool because it is the biggest. If it is the most popular then it must be the best. People pick their bank (and basically anything) the same way.


Pretty much, but your share of the payout is less with the bigger pools.

I stayed put through the whole low luck period with a few miners just to see what happened. The rewards almost doubled so the end result was roughly the same. The only thing I was unable to do was time the payout as precisely.

Hash rate is LOW. Not sure what to do though, they hit a block because of it the reward is impressive, 15% to my payout per block is crazy! When the hash rate was way up you got a lot of blocks but the end result was similar.

It's almost like Triplemining, I'd wait until they were around when they usually cracked a block (kind of the gambler's fallacy), go all in for a few days then reap the benefit. Of course if luck was like this I'd be over there now.

As of this typing the hash rate was 8.3 so I powered up another miner I hadn't been using. Feel like I'm at the Casino.

Slow few days hopefully will end soon Smiley

Repeat of last week, slow couple of days hash rate was low so they hit a few blocks so I'm right on the threshold of my payout setting then check it to find this. Then last week I ended up waiting and because of the hash rate they hit a couple and I'm back up to 50%. Probably gonna end up in the same boat again. Guess you can't win them all. I'm not even sure how I should readjust my payout, I had it pretty well timed for 7 days for a while, now it's hard to determine.

It seems worse than the end result really was though. Hash rate was low so I ended up getting payout in almost the same time because the rewards were higher. It just feels worse. When hash rate was in the 15-16 range they were hitting a lot of blocks but at 8.5 I'm getting double the reward (well not technically double by hash rate but I double for me as I did toss another miner on because the payout per block was better).

I haven't checked the graph in a while but clicked on it anyway. I'm surprised people were complaining about Slush's luck, BW.com is running about 3 times the hash rate 9 vs 30) as Slush right now but didn't find 3 times the blocks (16 vs 39), ouch!

I agree though a little decentralization never hurt.

How the hell are we at 200% for the day?

It's because between the longer blocks you seem to hit 3-4 in short succession which skews the percentage based on the way they compute it. So if a block takes an hour and a half which is 400% and the next block takes 12hrs which would be probably about 50% you'd still end up with something like 200%.

Another victory for centralized mining.
Finally, I have been growing concerned for some time now about attempts to defraud pools. The pool's luck has been on a decline for over a year. The luck on a few other pools has also shown a negative trend. While it is not impossible that it's a coincidence, this is something I have been constantly made aware of and am helpless against. There is no way to know whether it's just bad luck, a small bug in older miners (BTC Guild probably has the highest percentage of first/second generation ASICs) resulting in a few % of block-solving shares to disappear, or a large pool trying to hurt the competition (many of the largest pools have large private mining operations now). It would only take a fraction (1 PH/s or less could do it) to cause significant harm to a competing pool, and that activity could be masked by proxies and multiple accounts to be impossible to catch.
What do you mean with this?

I mean the pool's luck for the last 3 months has been 88~89% of expected block solves.  Eligius' 3 month luck is almost identical to that last I checked in their thread.  Slush doesn't give a 3 month luck but his 1-month luck is pretty close to that.  I do not know if that is statistically bad enough (Guild + Eligius pools in aggregate) to point towards something other than variance.  Both pools combined are only about 5% of the network, so 12% under expectation over 90 days might be something that could happen 1 in a hundred samples.  I'm sending organofcorti a message about it since that's his area of expertise.

88-89% doesn't seem anything out of the ordinary for variance for a 3 month period. Slush has had a bad run of luck in the last two weeks or so and the drop in hash rate certainly hasn't helped. Of course the drop due to summer certainly won't help hash rates any.

I don't know if older ASICs would have anything to do with it, an old 1th/s is going to do the same but use more electricity to do it.

Wow, low hashrate and many hours between blocks.  I have just a 50 ths mine, but have had to cut it back to about 40  due to the heat in my area.  But, I've definitely seen a drop in the payouts.  I may have to switch pools if the whole week ends up this way...

good luck with that.  Not like there are other pools with better luck.  Also, as soon as you switch the blocks are liable to come rolling in.

Yep, 3 blocks in the last 5hrs
11  Bitcoin / Pools / Re: [9000 TH] Slush's Pool (mining.bitcoin.cz); TX FEES + VarDiff on: June 15, 2015, 04:32:02 AM
Hit my payout and then quite a bit of the next due to the larger payout with the low hash rate. I ended up staying on as I had a migraine most of the day and didn't feel like reconfiguring pools. So of course there is another long block.

Has anyone noticed wild up and down hash rate fluctuations on these long blocks? I was watching and when they were hitting the blocks the hash rate was very steady on the two miners I was using on Slush's, with the long block it started going up and down in wild swings in short intervals. I noticed this the last few times they've had a long block. This doesn't impact rejected work, I think I only had 24 rejects in the last 12hrs, but I did notice that my best share stats are considerably lower than typical.

Low and behold I turned on another miner when I got home this afternoon since I was close to my payout then they hit 4 blocks before I checked again this evening.
13  Bitcoin / Pools / Re: [9000 TH] Slush's Pool (mining.bitcoin.cz); TX FEES + VarDiff on: June 13, 2015, 04:22:30 PM
I'm about 2 blocks from my set payout after that I'm taking a break too.
14  Bitcoin / Pools / Re: [9000 TH] Slush's Pool (mining.bitcoin.cz); TX FEES + VarDiff on: June 13, 2015, 01:08:02 AM
Almost 24hrs again... Luck has been bad.
15  Bitcoin / Mining support / Re: Visionman VP-1100 power supply dead on: June 10, 2015, 02:55:48 AM
As long as you know the voltages you could just lob the harnesses off and connect them exterior on the new PSU. I'd check eBay, sometimes you can snag a decent PSU on the cheap. I'm not entirely surprised by custom connectors, Visionman is a longtime server manufacturer and might have been using the same PSU for other things at one point.
16  Bitcoin / Pools / Re: [9000 TH] Slush's Pool (mining.bitcoin.cz); TX FEES + VarDiff on: June 09, 2015, 08:45:20 PM
Still dropping now below 10 Ph/s.  Maybe the recent slip in the BTC value has made some of the big players think hard about the cost of running their rigs, although BTCguild hasn't dropped as much hashing power.

9.8 now just checked. Helps smaller players like myself, if they hit a block payout is more. I'm actually tempted to go plug a few old rigs in in my basement.
17  Bitcoin / Pools / Re: [9000 TH] Slush's Pool (mining.bitcoin.cz); TX FEES + VarDiff on: June 08, 2015, 05:17:34 AM
If the luck goes up but the hash rate stays the same I have 3 miners ready to hop on at this rate of payout.
18  Bitcoin / Mining support / Re: Just starting mining today - Is 140-160 MH/s good? on: June 08, 2015, 03:02:57 AM
If you just want to try it for fun just get a few USB miners or cheap ASIC. Not that I suggest it, but as an example I bought a block erupter cube for $2 recently, which is substantially more powerful than your setup. $.10 per kW/h is way more than what I pay and I still won't run things that inefficient unless I'm using it for a space heater, but it would still be better electricity spent than running the computer for the hash rate.

After the 22hr block the next one was 47 seconds go figure.
20  Bitcoin / Pools / Re: [9000 TH] Slush's Pool (mining.bitcoin.cz); TX FEES + VarDiff on: May 31, 2015, 05:16:43 PM
Luck is dropping, it was artificially high because they had three blocks before the current long one and one was only 52 minutes which they consider 438% or something. Plus the long block caused the hash rate to drop, which probably doesn't help either.
