Um... a bit confused here. The link from
slushpool.com (see bottom of page) to it's maintainer Braiinz is to
http://www.braiins.cz/.
You're providing an entirely new domain - braiins-os.org - and that too from a newbie account.
How do users trust that you're actually THE Braiinz that's maintaining SlushPool? Maybe a linkback from
http://www.braiins.cz/ would help?
Frankly, with the number of scams going around, I would seriously think twice about installing non verified firmware, from a new source, on my antminers. Been bitten once already.
You dont have to install it, you just put it on an SD card and you can test it in whatever sandbox you would like to use.
Braiinz is the company that runs slushpool.....Braiinz OS is just a product they have put out. Is it really that confusing? Many many companies have a corporate website that is different from the website they offer products through.
