How to purchase a license for antminer z11?

What I dont understand is bitmain zec miners work with every pool but not with nicehash which is basically just forwarding the hash and why they cant open a port just for antminers all other bitmain algo miners work why not equihash

My guess is he is upset I keep disagreeing with him publicly on his blind blanket statement that only OEMs make trustworthy firmware.

But what do I know... I currently a have a 104F degree fever and may be delirious.

Wonder why Kano doesnt go after Bitmain?

Bitmain sent me link to the standard cgminer source repo. I will pass along the same.

Have a nice day.

YOU are distributing it.
So YOU must ensure that what you are distributing is properly licensed before YOU distribute it.

You make some claim about knowing about GPL licensing (GPLv3 in this case) yet seem ignorant of the above fact ... ... ... ...

jeez people...

efudd sorry you are having to go through all that bs ^^^
not sure what everyone is on about

anyways, thanks for the firmware, i have sent a pm for a license...

i was wondering if anyone else is still having problems with nicehash though?

i still get high rejection rates, and there are reddit posts from nicehash staff saying the z11 is just not compatible...


We have concluded that the Z11 is not compatible with our platform. The software in the Z11 is limited and if the server nonce changes/is different/different size the miner will not work or it will work just for some orders. Unfortunately, we cannot do anything about this so we ask that you contact Bitmain with this issue. Kind regards,

NiceHash Team

thanks for any help on that

*yawn*

You really should talk to bitmain if you believe they have some customizations that are not upstream.

Otherwise, here you go!

Nope.

I've requested you supply the source to something you distribute and that I have received.

If you wont supply the source (for whatever excuse you may come up with) then you do not have the rights to distribute it.

End of story.

Please supply me with the source.

0 dev fees, fully disabled.

PM me with count of units for mini/z9/z11.

I hope he didn't merit someone for breaking a license either. I also hope he didn't merit someone for not understanding more advanced things...

I'll give you an example of how you are wrong in your statement of "... cannot add [change/functionally modify/blahblah] without blah blah code..":

https://www.microsoft.com/en-us/research/project/detours/
... and here is an example of that type of capability in use in other works:
https://docs.microsoft.com/en-us/windows/msix/psf/package-support-framework

A significantly simpler way to look at what is going on here is that my work is effectively a custom debugger.

cgminer in Z9_2.3.tar.gz is exactly what bitmain ships, bit for bit and in the example of Z9_2.3.tar.gz, is built on
Antminer-Z11-fixed-718M-201904231321-sig.tar.gz downloaded from bitmain. So, If you want the source to the cgminer in Z9_2.3.tar.gz, then I suggest you do the same thing I've done, and request it from Bitmain.... they've ignored my request, maybe they will not ignore yours.

After that, you can go dig into the GPL faq at #MereAggregation, #GPLCompatInstaller, #DRMProhibited, #GiveUpKeys, and #GPLPlugins, among others for the relevant portions of how the portions which are "my" firmware (which is not anything bitmain ships, that is on them, legally and ethically) are not applicable. Other portions which are, you already have the source code to by proxy of downloading the bundle itself (javascript/html in /www/pages/*).

Two short examples are that my work does not "make function calls to each other" or "share data structures", and by proxy of #GPLPlugins, are not in fact covered by "form a single combined program". Further, ".. communications between them is limited to invoiking the main function of the plug-in with some options and waiting for it to return, that is a borderline case".

Further, if my loader (read: installer) and associated work (read:  drm, giveupkeys, etc.) only use the publicly documented APIs (which it does), then it is not a GPL derived work (also, GPL FAQ, but I haven't had my coffee yet this AM and am missing a quick location to the reference).

Hi,

What are the benefits of a license?
How much is the license and how can I obtain a license?

Thanks

You CAN NOT add or modify #xnsub in a firmware without modifying the cgminer code.
Also, all bitmain miners are built off the cgminer code.

Your Z9_2.3.tar.gz uses a version of cgminer in it - 4.9.0 - I've downloaded it and checked.
You've stated

Where is the source code to your miner running in your firmware?
That is mandatory if I request it, since I downloaded your binary.

Hopefully frodocooper didn't merit someone for breaking the cgminer license ... ... ...

Yes you did 
Thank you for your kind help.

Pretty sure I responded to you on the mini thread. Follow the instructions for installing the z11 firmware linked from https://releases.broked.net — the SD card base method... just install whatever non-signatured firmware you want as the last step. The same recovery image will work for v9/Z9/z9mini/z11....

Hi,

I by mistake updated to the new antminer z9 mini firmware from Bitmain's site. Now I am stuck with Antminer-Z9-Mini-fixed-500M-201905171644.tar.gz.
If I try to change the firmware it says the file is not signed. I even tried the lastest Efudd's firmware but the same problem.
I cannot even SSH to the miner like before.
I am stuck.
Any help is highly appreciated.

Thanks.

Darn... I responded in your thread about the problem. Hope it helps you!

Hello Dear efudd
recently I have bought 3 second hand miners (m3 ) after I connected them to my farm everything messed up, I tried installing firmware which I have been using last 2 months without any problem , but it didnt work , even I isolated each miner ( turn off all others ) and install firmware using whatsminer then turn off updated miner  , and went to the next miner... but this didn't work too , Is it possible that my lap top is infected? or maybe i should use sd card to flash them ? how can I solve this problem ?
here is the topic  : https://bitcointalk.org/index.php?topic=5151878.new#new
i will be happy if you can help me

These are crazy power hungry when pushed. Join the discord as others may have some views and experiences to share there in the z11 channel as well... but the trick at that point in your testing would be to see how much power you can pull back out while maintaining a given hashrate. Tuning each board may help you optimize the power draw as well.

Some folk have cheap power and don’t mind the draw, others are undervolting to maintain stock rates with lower power draw.

Hi,

what settings do you use on Z11?

I hava a problem with large power comsumption.

791 mhz /960 and i get 2100-2200W with 155-160 kh/s

Does anyone get better results? I have 2000W PSu so its problematic

on a new Bitmain firmware I get 135-140 kh/s and 1500W only.
