I see you Phil!!! Up to 10ph now! and the Pool is over 100ph!!! 

How does a rental work? I have heard of it but never looked into.
Who do you use?

Kano, 70hours no blocks.  I think it might be a good time to ask your Goddess for help, she helped us last time! 

[NomadGroup]

Last time I posted a BLOCK was found, so let's see if I have the magical touch. 

Please make at least a couple of posts then! 

[ordimans]

I have to say this is getting to be a very annoying Block.

Also, since I tossed this up in another forum and got no answer I am going to toss it up here, maybe one of you guru's knows what's up:

On the Antminer s9:

Model   GNU/Linux
Hardware Version   16.8.1.3
Kernel Version   Linux 3.14.0-xilinx-gb190cb0-dirty #57 SMP PREEMPT Fri Dec 9 14:49:22 CST 2016
File System Version   Fri Jul 21 05:15:25 EDT 2017
Logic Version   S9V2.23
BMminer Version   2.0.0

Does this model only have one set of chips with temperatures? The reason I ask is because all my other s9's, older, have two sets of chips with temps, but this one doesn't. But it is hashing the same speed.

s9-v.2.23



s9-v2.00

It's same that first screen on my two 13.5.
But on Awesome Miner, it seems i have all temperature.
Chip and PCB.

The strange thing, is the first PCB is higher than others.
And between my two S9, 8°C in difference, fan is not same...
One speed at 4300 and temperature is 57, others 5300 and 65....
I will post in S9 topic

It's a good idea to rent many hash power on Nicehash ?
Who is ready to donate

Man, you are my HERO

Awesome stuff... this block will be remembered once found

GO PHIL!!

Just curious if it is possible for a block to not be able to generate an answer (go through every possibility)?  I wonder if anyone has analyzed how many possible answers there are for the various difficulties?

Also a tech question / idea for Kano...  Are shares distributed sequentially or randomly to miners around the world?  It seems that randomly picking shares may improve our luck (may make it worse too).  I am a 30+ year web / c++ developer that has combined dedicated servers into a worldwide distributed digital signage solution.  I have a concept on how to code random share distribution to deal with the trillions of shares.  I am tempted to code up my own pool but have no idea where to start and have paying customers to keep happy.  Kano, if this is distributed sequentially, can we chat?

Is there a record for longest time without a block on this pool?

Is there a record for longest time without a block on this pool?

It's the longest one since I started mining I can say that. I dunno if it is a record for the pool.

Kano just mentioned the record one page up.

If it wasn't possible to find a block, bitcoin would stop

Each individual hash is pseudo-random.
You'll not be able to find an association between two sequential hashes other than to say 'double-sha-256'
i.e. no.

Also, shares aren't distributed, work is.
The base work is the same for everyone on the pool, but the coinbase transaction is slightly different for everyone and somewhat sequential.
Each individual work item can produce more values to hash than the size of the difficulty, so you expect all work to be able to produce a block, but of course no one is able to  actually exhaust a work item in 30 seconds unless they use a proxy to a VERY large number of miners (more than exist)

You wont be able to convince me of any effect due to the sequential client ids.
It effectively doesn't exist.

Time, again, for the Block Dance! it never fails BTC

OK time to call in another anime Goddess and request help from her - Nagi:

Thanks Kano.  Yes, this is all super deep stuff and thanks for your time explaining it. I've only been into mining / crypto for about 2 months, so super green on it all.  So based on your comment, the miner does not even complete the work that is assigned to them?  That must make things insane for the server software.  So does the remaining work get distributed back out to the miners again somehow or is it just ignored?

The basic explanations I have seen of mining on the web are to compute the sha256 of the block plus the number 1, then 2, then 3.  Firstly, I am not certain this is even close to what truly is happening.  If it is somewhat close, then I would assume that each miner is given the block info and a range of numbers to work on sequentially.  I have no idea of the starting and ending range for work (and I am sure it varies by miner), but lets say the first miner's work is 1 through 1000, then my thought is rather than sending 1001 to 2000 to the second miner, the pool would send a random unprocessed starting point.  For example, 1 trillion to 1 trillion + 1000.  The third miner may be 1 billion to 1 billion + 1000, etc.  Beyond that, each pool server would need to have their own range since the servers cannot communicate around the world fast enough.  On each server, a memory cache would be filled in with the next few hundred block ranges which would get mapped into a local database in the background after being assigned and repopulate more random blocks for future requests.  Of course that all gets even more insane since every miner has an individual difficulty but perhaps that could be figured in. 

Eventually someone will be assigned 2001 to 3000 when it randomly comes up.  Obviously if the block answer was found in the 2001 to 3000 work group, then this method dramatically slows what a sequential operation would do.  Anyway, that was my thought - but it is highly possible that is already happening on every pool in the world.  As I said, I'm green on this.  Thanks again and it was a pleasure to chat with you and be a part of your pool for most of my short mining life.

Not surprised we are struggling to get that block...at, 81hrs and 11 mins we only had 15 users...well we had 1111 and that's 15 in my book
