Definitely a cool project... Store of value with mechanisms to constantly increase price.
|
|
|
|

Check out Eclipseum. Anti fragile store of value that runs on the Ethereum network. Uses ETH volatility to generate price increases.

Looks like a unique idea!  |

Interesting but not a buy. Is 7 USD factual? What algo/coin?
https://whattomine.com/asicCurrent profitability is $9/day on DGB-Qubit Those numbers fluctuate quite a bit, so look at the top 5, which are all $7-9/day after electric. |

The efficiency isn't a huge improvement over the X10:
X10 @ 630W for X11 algo or 63W/GH
G28 @ 1300W for X11 algo or 46W/GH
The other algos seems to have a similar efficiency increase. Not insignificant, but not a game changer either. To give an idea what's possible efficiency wise for X11:
Spondoolies SPx36 @ 4400W for 540GH is 8.1 W/GH
Innosilicon A5+ @ 1500W for 65GH is 23W/GH
The one advantage here is there are multiple algorithms available, so Bitmain can't nuke the algo and make the miner worthless.

Please don't overprice this one... profit is only $7/day

Also interested in this if you know of lower cost / better ROI FPGA parts.
|

Gotta agree... 200-300 day ROI is too much.

I am close with the seller.
I can get these under retail, they will soon be available at bittawmart.com
how soon is "soon"? And how low is "under retail"? Available at a slight discount on Pangolin website now. Possibly interested in 1-2 units. |

Definitely interested in both developing for this project and building an FPGA rig.

From the new image: Start-Date: 2018-04-08 20:31:58
Commandline: apt-get install secure-delete
Start-Date: 2018-04-08 20:45:48
Commandline: apt-get install testdisk Covering their tracks this time, then making sure the secure delete worked using the same program used on this thread to extract deleted files. Hi Baikal!  LOL, that is hilarious! Too bad they forgot to securely delete the 3 earlier versions of the STM firmware on the fat32 partition. Nice find! Anything useful in the old firmwares? |

Yes I saw this.. Baikal is a Russian electronics company .. they produce the asic chips and I may be able to acquire them. The hashboard is what would be otherwise proprietary but according to prelminary discussions with my engineers, can likely be cloned or functionally matched. So my question is if someone has already photos or can make a bill of materials or components they see on the board.. or if they would sell me a working or non-working board and I'll get it done myself .. besides the asic chip listed (all the other transistors, etc.) I can put it through to see if they can source everything.
I suppose I was hinting for partners in what may be a much bigger project, as I've already decided I'm going to make the investment for the chance to get it done provided the required chips are available.. some of the skills and perhaps material that this group may have, could make it a reality in which case there would be a very small group of people with access to the resulting product. Yeah it's maybe a big dream, but it's worth it. Multi algo miners are the way to go and to understand and be able to create more efficient ones or more capable, isn't so far fetched.
In the meantime, my other question was a programming one. Isnt the firmware what is provided to flash the system or is there a rom that is pre-programmed with base functions that would have to be decompiled?
If you can source the chips, that would be a huge step toward cloning the whole miner, but I'm having a hard time picturing how you would do that ethically. I don't imagine Baikal is selling these chips on the open market. If you decide to develop your own systems however, keep me in mind. I have some unique ideas about how to design a multi-algo asic to target a group of algorithms, but don't have the experience or resources to implement it in silicon. I also have a good idea of which algos and networks to target without causing a D3-level fiasco. Keep me in mind if you actually kick off this project. |

I sent in an email asking them to release their firmware and software.
Senseless, did you ever get a reply on the software or firmware? |
|
|
|
|
Assuming this is a legitimate project, how does your product differ from Baikal's design?

There are thermal pads under the heatsink. I have replacements ordered, but I'm only running myr-gr, so not too worried about heat. You could probably replace the thermal pads with Arctic silver, but I'd be worried about it getting on the board.
There's a small heatsink on one side, and a large one on the other. The chips are all under the small one, so dont worry about taking them both off.

I've tried flashing the Giant B firmware to an X10 and running the Giant B image on the Pi but no luck converting an X10 to GB or using that firmware image to overclock (so far).
Interesting that the controller boards are the same, but not surprising. I can't find the difference between those two STM model numbers anywhere online. Could the last couple lines just be batch numbers?
I DID take the heatsink off an X10 and the model number on the asic is this:
[Baikal Logo]
BK177280
ND33U
I'd upload a picture, but the chips are too small for my potato camera.
<Your move Giant-B owners!>

First  Here´s the tmp-file from a Baikal Giant B. KLICK Is it possible , to add the hidden Algo to the Baikal B? Awesome! Thank you for the upload. I've been able to confirm that you can't re-image an X10 to a Giant B by simply pushing the STM firmware down and using the Giant B image for the Pi Zero. The structure of the firmware is very similar to the X10, but it looks like the algorithms are hard-coded into the firmware. I was hoping the firmware was just acting as a USB to SPI translator, but it looks like it's doing more low-level work for the algorithms and to drive the chips. I've also been able to get a successful decompile using Binary Ninja and the Thumb2-linux architecture, but this will only get you machine code afaik. Edit: Here's an upload of the GB and GX10 firmwares and binary ninja decompile databases: https://ufile.io/ues7gIf someone knows how to diff two SQLlite databases, that would be helpful. |

Bumping this thread up. If anyone has access to a Giant B, please run this command and upload the file somewhere. This will help significantly with overclocking both the X10 and Giant B. sudo dfu-util -a 0 -d 0483:df11 -s 0x08000000:leave -U /home/baikal/tmp.bin If you have access to a Giant B and need more explicit instructions, just let me know. |

If anyone has access to a Giant B and would be willing to upload the firmware, please let me know. I've been working on an overclock for a while, and from what I can tell the frequency multiplier is either hard-coded into the firmware of the STM32 chip, or hard-coded into the ASICs. I'm ordering parts now to try a hardware mod to see if an overclock is even possible.
