How to add support quark_hash in stratum-mining?

[Blisk]

I have also problem of updating database, I use mysql and when I check logs from stratum it all shows ok.

Code:

but I when I look at my website MPOS pool in Finder, Round, Blocks, etc. All is empty, except dashboard where all is ok, pool is on about 8000 Khash.
all database user and password is ok

I am having an issue when I try to connect to other pools. I can connect to Slushs pool fine but when I try to access another pool using a bat file to start up the stratum proxy I get this error:

Failure: stratum.custom_exceptions.TransportException: SocketTransportClientFactory connection timed out


Any idea what the problem might be ?



*Edit: I figured it out. You need to remove the 'stratum+tcp://' when adding an address that has it.

Hi,

I'm testing out the latest git version of the slush0 mining_proxy in Linux, and I receive the following error when trying Scrypt:

[fmarcosh]

I need help for configuring the stratum proxy and the workers in the pool.
Currently I have a KnC Saturn working at 320 GHps and 2 Antminer S1 working each @ 193GHps, with 3 separate workers in btcguild using eu-stratum.btcguild.com:3333 as stratum server for each worker. All 3 workers has 256 difficulty set in the pool settings.
I'm trying to use the Stratum mining proxy but I have some doubts on the proper settings.
I think I should use another new worker that was responsible of all the shares with a new difficulty of 512, so the stratum mining proxy should point to this new worker with the -cu USER_ALLWORKERS -cp any.
So with these settings the traficc between the proxy and the pool should be restricted to shares with 512 of difficulty and minimize traffic.
First of all, are my guess ok?
The problem is that it doesn't work as expected in a windows version of the stratum proxy with the 2 Antminers connected because all shares appears as rejected by low difficulty.
Any suggestion?
Thanks in advance.
Regards.

[Gamer67]

Why are you using a proxy for the Ants ?  They have stratum built in.

[fmarcosh]

I'm trying to use a stratum proxy only for lowering traffic

Is there a way to let the server force a new 'extranonce1' on the miner without letting it disconnect ?

I'd like to know this, too.

Hello guys,

Are there any plans to introduce p2pool compatibility?

Cheers.

Why are none of the questions in this thread about the stratum mining protocol, which is what the thread is about?

Fine, I've got one

If someone (me) wanted to draft a proposed extension/standard stratum message, who would be the appropriate "body" to submit an RFC-like proposal to?

This thread is as close to an RFC like body you'll get since the pool operators and mining software authors worked from it. Thus the defacto standard for stratum is developed and discussed from here. Of course if you're interested in doing something for the sake of some altcoin's benefit only, I'm not interested...

Thanks for the quick reply - it is actually somewhat alt-coin related, but not tied to any coin specifically.  Once I have my idea fleshed out, I'll post it here.

Hi,

can somebody explain me what is the session in stratum?

{"error": null, "id": 1, "result": [["mining.notify", "ae6812eb4cd7735a302a8a9dd95cf71f"], "00000001", 4]}

Can I ignore this parameter? What is it? Can I set this parameter?

Thanks for reply

Analyzing stratum myself and it looks like this one isn't being used anywhere. Maybe reserved for later usage?

Anyway, could someone explain to me how many hashes are solved if difficulty by stratum is set to 32.

I found this: http://bitcoin.stackexchange.com/questions/3621/how-do-mining-pools-figure-out-the-hashing-speed-of-the-connected-miners

I can count number of shares and I can determine share difficulty out of protocol. If I have recorded shares (+difficulty for each one), how would I go on and calculate total amount of hashes? And does it depend on hashing algorithm?

[djeZo]

I do find only old threads, that are not related to stratum mining, like this one: https://bitcointalk.org/index.php?topic=63273.0

All these calculations yield wrong result.

The closest one I came to was when using following formula: H = num_shares * pool_diff * 2^16 / time_in_sec

This is in case pool_diff = 32

Bad guess.

A 1 diff share has an expectation of occurring, on average, once every 2^32 hashes.

So it's 2^32 not 2^16

So if you submit S shares at difficulty D over T period of seconds, your calculated hash rate would be:

S * D * 2^32 / T

Which I have called in other threads: Your "Paid GH/s" (if you also divide by 10^9)

Edit: FYI
S * D = DiffA

[djeZo]

I thought this would be the solution too, but I get extremely high value, 500.000.000, when in fact doing only <200kH/s. So this formula can't be correct (at least not for scrypt mining)
