QUESTIONS about mining , Help please

[stigo]

Hello,

I have questions and I want to understand some points about mining pool:

1- If a mining pool wants to know the reference or serial number of my miner or GPU , is it possible for them to do this with a new firmware ? BTCtools can know the reference of the ASIC miner for example .
2- How mining pool ensures security ( I know it's complicated ,if you have articles or something not too technical it will be good for me ) , or what are the main issues with this.
3- The pool fees depend on the hash rate of my miner ?
4- Can a pool work for another pool ?
5- DO the mining pool receive all hashes of my miner ? I mean if i have 10TH/s then the pool will receive 10T hashes each second ? they store this or just check if a hash is valid ?

Thank you very much

1) Maybe I am not sure

2) This is very hard to give a good answer to. It would take a lot of time and effort to explain. Short answer is they are merely a tool to help or hurt is possible depends on how they are being used.
 
3) Yes if you are huge you can get discounts.
4) Yes Nicehash does that
5) No there can be rejects and invalid shares or stale shares. If you are send 10th and they are giving you credit for 9.8 th or higher you are okay.

Thanks ,
Do you know if the asic miner sends hash by hash to the pool or it sends batch every second ?

That would require massive bandwidth for the pool. Virtually all set worker difficulty to produce an average of 18 shares per minute.
You should checkout the various help topics this pool has. Going through the various Help topics there should answer most of your potential questions.

As far as miners sending serial numbers or a pool requiring you to provide that -- AFAIK that is unheard of and there would be zero need for it. BUT - yes a pool can within limits identify a miner as to what it is (and firmware running on it) because part of the response a miner sends out via Stratum has data fields assigned just for that. Kano does that to track performance of miners connected to his pool -- something it seems most other pool operators either do not do or if they do, do not share that information with the pool users. If you read through the Mining Details section of that Help area you will find that each worker has a unique ID generated that the pool uses to track your efforts.

edit: mainly fixed typos

Thank you for the link , very interessing . does a share means a batch of hashes or only one hash ?

[NotFuzzyWarm]

Shares are the work being sent to the miner and results sent from the miner back to the pool. They are one-shot data transfers, with the pool/miner talking to each other 18x per minute (on average). Read the Workers part of that link for details.

Ok ,I get it ( may be ) :
In theory , every miner must send ALL hashes to the pool , but this needs a very huge bandwidth. So to limit this amount of hashes, the pool applies a FILTER to eliminate non-interressing hashes. The pool sets an initial difficulty to the miner and forces it to send only hashes that meet this difficulty.
The pool adjusts this difficulty according to the performances of the miner ( hashrate ) in order to get 18 shares per minute. In the meantime, this can be a metric to estimate the hash rate of the miner .

Is it like this ?

Yep. Spot on
