i didnt know that they did merged mining .... ive got some payouts coming, 
jumped to btc.com pool a while ago before the 6.4 eh down to 4.9 eh 
it did seem i had higher payouts with them even with the longer then usual times
with the merged setup paying out id prob come back  Shocked

well slush pays pplns not pps so the smaller the pool the more you get per block found. so if luck is good you do ok. I do not think slush is sitting with good luck atm - I just looked and they are at over 13 hours for their current block.

Yeah, 16+ hour blocks are getting the new normal it seems. I wonder when the day comes we will only find 1 block or no block at all.

For every period with the same difficulty I calculate what I should have gotten and what the payout on Slush was.
For 11.890.594.958.796 it was 91,6%, for 12.759.819.404.409 it was 90,0% and this period with only 2,5 days to go it will probably even be lower.

But hey, April, May and June were good months, and we don't even have to go back that far to "even out".
But I have to admit, on Slush three periods around 90% is a really bad stroke of luck judging from my experience.


I never really cared much about the NMC, but after this post:
The NMC rewards for the previous year will be paid out within a few weeks.
We are very sorry for the delay.
And with the luck being what it is, an extra payout would be very welcome.

Come on guys, I really like what you are doing with Braiins OS, but please give the pool some attention too.

hi total newb here, bitcoin fan and miner, i have join slush pool seem to me at the worst time to see there luck... im just trying to understand something if there is 57eh mined at this time (from google) and slush pool has 4.5 eh witch represent 11% of the world mining power why does slush only end up on average with 7 block a day (from my own statistic) rather than 15 block (11% from is hash power). i know the luck is bad but that much?? i mean it is half the expected return no?
as i said im a total neb so maybe i dont understand how thing work...   
thank you

None of the pools (except mine) show the statistics related to multiple block results on the pool that would tell you if anything is ok or not.

It's not hard to do and I guess you could do it yourself, but I guess either they're all statistically challenged, or like to hide what's going on.
These stats also show to the pool operators if something is going wrong.
Though none of them clearly understand how to do a reasonable level of analysis to determine problems.

Even slush's so called 'proof' is not an actual proof of hash rate.
Slush has multiple cases where things have gone wrong and they've ignored it, even since they added their fake 'proof'.

Though I guess since all the other pools are just as bad or worse (some have no statistics at all and you could never know if anything was wrong) you have to put up with the poor quality service you get ...

this is why i make my own statistic... i keep a journal of how much block was mined everyday since in join slush 1 month ago. and maybe i dont calculate right but from the hashing power of the pool 4.5eh (slush pool) vs the total hashing power of the bitcoin community 57 eh (from google) it seem to me that somehow and somewhat those number should be at least related. and from the month i have passed on slush pool, it seem like that hashing power of slush pool does not bring its share of blocks and i wonder why. but like i said maybe it is me who doesnt calculate right. i am new to mining but i would think that 11% of hashing power would bring 11% of blocks and not 5%.
No?

A simple example, if a pool was to get 80% luck for 250 blocks, The CDF[Erl] of 250 events with a mean of 80% luck (1.25) = 0.999886
https://www.wolframalpha.com/input/?i=CDF%5BErlangDistribution%5B250%2C+250%5D%2C++1.25%5D
This says that should happen about once in (1/(1-x)) * 250 = 2.19 million blocks the pool finds Smiley

I, of course, don't keep track of this pools luck or the number of blocks it has for that luck, but ... if it is having 80% luck over 250 blocks ... well, not sure why anyone would be mining here ...

I think you'll find your 50% luck figure is wrong though, since 80% luck is already far beyond likely what you would expect to happen.

... since redoing the calculation with 50% instead of 80% gives ...
CDF[Erl] of 250 events with a mean of 50% luck (2.0) gives .... about 1 in 2.1x10^37 blocks
So yeah that will never happen in the life of the universe Smiley

The assumption of luck is that all gear mining at a pool works with proper firmware and submits shares correctly.

So plain and simple mining gear with bad firmware does exist and could be pointed at slush or at other pools.   

What can a miner do to combat this?


He or she can mine solo with their own gear.

He or she can mine at a pps+ pool which pays no matter what.


Do I know slush has been attacked with bad gear that is with holding blocks no i do not.

but i do know mining at a pps+ pool that  protects me from this attack.

i do pay more in fees for this protection which is my choice.

I see BTC as the super highway and alt coins as taxis and trucks needed to move transactions.

No?

A few months ago the total hashrate was 57 Eh/s, the total hashrate is much higher now: https://www.blockchain.com/charts/hash-rate (and remember that the numbers in this graph are estimates).

If you calculate how much bitcoin you should get with your hashrate on a site like Coinwarz, and you compare this with the 10/50/250 block numbers on Slush, you will see these numbers are correct. (And yes, we are on a really bad stroke of luck right now.)

Or mine on a pool that does keep track of this and make sure the effect on miners is minimised ... which is easy enough (for me) to do.

so looking around found  Found

https://www.multipool.us/     


looks like they pool hash and point it to slush pool but have a diffrent payout system.

Look at the block explorer on their web page and compare it to slush pool blocks

Identical ?? or what are they doing ?

It doesn't look like it, from their wiki page it seems that they wait to get rewards from slush before sharing it out to their users.

So ... I had a discussion with gmaxwell about ... a while ago ... and he said that the large pools don't purposely make empty blocks any more since it's no longer necessary due to bitcoind being fast enough to not need to do it

(though my pool has proven it was never necessary anyway by never having empty blocks, due to never ignoring all transactions if any are available)

Anyway, today slush produced an empty block 603351

They also found the block before it, 603350.

Now when they found block 603350 and 603351, my bitcoind debug.log shows:
Code:
CreateNewBlock(): block weight: 3965699 txs: 2506 of 8755 fees: 0.43025836 sigops 17480

CreateNewBlock(): block weight: 3965648 txs: 2468 of 6252 fees: 0.20234402 sigops 18841

UpdateTip: new best=000000000000000000136973e9bfdfc7151d9929d33fa95827a4107ec5115eed height=603351 version=0x20400000 log2_work=91.322681 tx=473721414 date='2019-11-11 20:31:41' progress=1.000000 cache=79.0MiB(579654txo) warning='56 of last 100 blocks have unexpected version'

CreateNewBlock(): block weight: 3965469 txs: 2463 of 6290 fees: 0.20634536 sigops 18749
i.e. there were at least 8755 transactions available before they found block 603350, of which they used about 2500, and over 6200 transactions available for block 603351 after processing block 603350.

i.e. they purposefully created an empty block 603351 value 12.5 BTC instead of it being at least 12.70234402 BTC and using over 2400 transactions.

So I beg to differ with gmaxwell about his claim that slush pool doesn't code to find empty blocks during a block change Smiley

Or, they are running hardware that is stressed to the max and cannot keep up. Or they have something very poorly configured.

I believe in the concept of never believe people are doing something wrong deliberately. It's usually just incompetence. (Look at the Trezor vulnerabilities)

They might not want to generate empty blocks, they might not even be trying to. They just are.

This could be the case but it's still a poor excuse not to improve. Their entire service is based on mining blocks and the transaction/rewards to be as profitable as possible for their miners. Transactions are the biggest reason for a miner to choose a PPLNS pool, so not doing everything possible to avoid empty blocks is just letting down your clients. On the flip side of that Miners exist to process these transactions, so if there is even 1 in the mempool it should damn well be in the block. I haven't been on slush for quite some time, but I think the problem has been they are big enough they don't care. There have been a lot of complaints about things like the merged mining rewards, and nothing has come of it. Unfortunately a lot of people just get complacent and don't reevaluate often enough, and if they are still make mad bank on the fees for the blocks mined without facing any real consequence where's there incentive to improve.

I didn't say it was an excuse for them not to improve. IF it's anything I listed it's a WORSE reason not to improve.
Nothing was particularly difficult to fix. Hardware is simple, to stressed add more. Configuration check around till you find the issue.

I started on slush a looong time ago. Left and never looked back. As you said between the merged mining and things like this it looks like they just don't care.
