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

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.

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 Wink

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.

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

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.

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.

How to add support quark_hash in stratum-mining?

So I gave the windows binaries a try, I installed the proxy on my Windows 7 64bit VM and connected my Avalon miners and ASIC USB key machine to the proxy. I noticed I get around 109ms and a lot of rejects show up on the avalons, yet if I connect direct to Slush's site I don't get nearly as many rejects on my Avalon's.

Is there a reason for this?

My network consists a Dell 6224 Gbit switch, CAT6 cable and a Cisco Gbit firewall.

A 30s refresh (vs a 60s refresh) will increase your chance of getting higher transaction fees ...

Thanks Kano.

Will try reducing the refresh interval. Right now, I'm running with 150.
I just found my first block: 255822 !!! Only 0.0667 in transactions.

Slush's document stipulated that it should refresh at least every 60 seconds. If it's much longer than that, since you're dealing with raw sockets that can quietly die, there is no way for the miner software to know if the socket has disappeared, so cgminer uses 90 seconds between messages to say the pool has died so you cannot increase it to much more. Updating it more frequently includes newer transactions but requires more refreshes on your mining software, and vice versa.

Thanks Con. I appreciate your explanation. I'm trying to understand how this works.

So basically, miners work on solving a block and server gives them new "merkle_branch" when this refresh interval is reached or a new block is detected., right? The previous work is discarded on the miner side or is submitted? It should be valid if prevHash has not changed (ie new block was solved), no?

Would faster refreshes give miners a slight edge of finding easy blocks? If everybody and their mother is getting merke_branches every 60 seconds, and you get them every 35 seconds, if there is easy block to find, you would have a better chance of starting to work on it first. But then again, it might be a toss since working longer on a given merkle_branch might actually help miner solve the block.

Running at 150 seconds now, no issues so far.
