401  Bitcoin / Pools / Re: [ANN] Stratum mining protocol - ASIC ready on: December 24, 2014, 09:06:28 PM
Could someone explain me what is the purpose of the mining.get_transactions stratum extension  ?

I am the developper of the stratum proxy https://github.com/Stratehm/stratum-proxy and someone reported me that the last BFGminer versions does not work with my proxy due to this extension. What should the pool respond if it does not support this extension ?

Thanks and merry Christmas  Smiley
A normal stratum error is fine.

Try BFGminer version 3.1.1,that one worked very well....way back when  Wink

http://luke.dashjr.org/programs/bitcoin/files/bfgminer/3.1.1/
Good idea. If 3.1.1 works, it makes troubleshooting 5.0 much easier Smiley

I just bought this miner a few days ago from eBay for the sake of getting 30+ GH/s.



I hooked this thing up to a 200W PSU and an Ubuntu Server box.
I can't seem to get it past 8Gh/s. The only time I see above 8 is when I first boot up bfgminer and it warns me about the temperature.
I have plenty of cooling for this thing, so I dunno what's wrong.

If someone can help me on this issue, that would be great.
The hardware error rate looks really high - is it possible that it may be defective?
Maybe try cgminer (you'll have to mess up your drivers with Zadig if you use Windows... Sad) and see if it performs any better with that? (if it does, let me know and I'll see if I can help fix BFGMiner..)

Hi all,I have a small question and I have not been able to find the answer in the read me files.

How do I use bfgminer to mine scrypt_n? I use the --scrypt but it just rejects every share submitted.

Sorry to be ignorant but I am not an experienced miner so any help is much appreciated. If it matters,I am on win7x64 and using GSD orbs and Gaw\Zuess miners.Thanks :-)
scrypt-n is not supported at this time.

Edit: Also, the only hardware I am aware of supporting scrypt-n is KnCMiner's Titan, NOT gridseed or zeusminer...

Feature proposal: client report hashing speed

It would be very useful for stratum protocol to include a client message to report hashing speed. Today's miners (SHA256, Scrypt and others) vary a lot in terms of speed. For efficient initial vardiff handling, initial miners distribution in dependence of speed, etc. it wold be very useful for a pool to be informed by the client at what speed it is hashing. It would be nice if this would be implemented in the stratum protocol.
slush proposed a mining.get_hashrate for this a while ago... not sure if there's any specification/documentation of it though.

Is it possible to point BFGMiner Proxy at another BFGMiner Proxy as to aggregate hashrate from multiple sources and redirect toward intended target?

I thought I had done this in the past using slush's proxy..  but it doesn't seem to want to work.

I get "ssm: Failed to subdivide upstream stratum notify!"

Anyone know?

thanks in advance!
You'll need to hack the code for one of them.

work2d.c:work2d_init assigns work2d_xnonce2sz = 2

If you assign this to 3 on your pool-side proxy, it will divide 4+ byte pool extranonce into 3 byte chunks, and then the normal BFGMiner can divide that into 2 byte chunks.

Hey Luke, any luck with rockxie and his "New R-box"? im not sure if its my hardware doing the bad hashing (i suspect it is) or if its the lack of information you're getting from rockxie
Nope.
hm.. having the hardware wouldn’t help you much ether, am i correct?
They did send hardware... which is part of why it's confusing that they stopped communicating.

I haven't tried them, but there are a number of GUIs available for BFGMiner (yes, including BFL's EasyMiner - which should work for any supported device).

The public interview was not the important part of the conversation.  I for one would welcome Gavin's field report.

You'll be waiting on that one for a while. He starts these news threads then hardly ever returns to them. The only ones that warrant a second look are the ones where he's being attacked. I doubt he really looked at those twice. Most likely someone told him, "hey dude, LukeJr is talking shit about you in your thread" so he responded.
Uh, what?

The other software (OSCAM with USB Easymouse) runs the USB device /dev/tty0 (/dev/EM-ICE) but after a USB scan or other messages the OSCAM los the USB device on USB0??

regards
So don't scan USB0...?

I think something small like Rock Miner did was pretty cool (the 100GH unit). Maybe make a pod like Bitmain...something that does not require a computer PSU to run.
To not require an external PSU means they have to put in an internal PSU.
Which means additional certifications are needed, and can sometimes delay customs/shipment...

(that being said, I agree it's nice to have)

10Gh USB miner? Cheesy Maybe?

Maybe this could be a return of the super cheap USB miners.
The component overhead of USB miners is still a problem.

1 MCU, 1 DCDC, 1 USB-to-UART chip, for each 2 chips, is so much cost to take.

If we make a 8 to 9 chip USB miner (about 40G), DCDC cost can be saved. But USB2.0 does
not have enough watt capability to power it.
One could drop the MCU and use a USB-to-GPIO (or similar, depending on chip interface) to offload work onto the host....

After the thorough testing of single chip boards, we are going to test boards with chained chips.
Do you have enough test units to send one so I can try to have BFGMiner support at time of production shipping?
How about specs?

so question, I know that BFG works with the gridseed 5 chip pods for scrypt mining. What about dual mode with the gridseed device?  I am pretty sure the first comment to come my way might very well be why would you want to do that.  I realize profit for sha/scrypt mining on the little buggers is nonexistent. I am just at war with the pc at the moment trying to do it.  currently I am running cpu&cgminer to accomplish this, but it is not getting the results i think it should be.
AFAIK only the DualMiner ever supported SHA2, and on the GridSeed devices, the PCB design was such that SHA2 overheated it.
In any case, the BFGMiner driver for gridseed only supports scrypt, and nobody has mentioned plans to add SHA2 support, so unless you're prepared to write/contribute code, you won't get very far with that Wink

Hello,

you know about when the Bfgminer support the Technobit HEX8A1 miner?

regards

... &  other Technobit hardware.
Only support for HEX16A is planned at this time, and possibly only for Mac/Windows since they're incompatible with Linux.
We'll need samples of the newer hardware to support them (although maybe it's possible they use the same interface and would just work).

forgive me for forgetting, what is it about them that makes them incompatible with linux?
I don't entirely remember at this point...

All I can say is your OS appears to be broken.

Why are you trying to install debs manually? Did you run aptitude update before starting??
