2.5% still leaves 97.5% for us greedy miners. I got no problem with that.
Every blockchain needs one 'miner' to run. 1 or 1000000 miners, coins generated daily stays more or less the same.

and his miner was released which cause an incredible increase in hashrate which did drop the price
I have been using claymore's miners and I still am sometimes. There just is no reason to do that anymore when there are faster opensource miners available for every 'big' profitable algo.
if his miners are more optimized in the future than there is more reason to use claymore's miner and pay him the 2.5% dev fee... it really depends on how much better he can make it. though i still think that fee is a little high and think the fee should be more like his eth miner at 1%.... but thats just personal opinion... his groupies are fine with it so all the better that claymore gets the money rather than them.
we can just use our opensource miners in linux and save ourselves the 2.5%

I like how you say "his users" as if we are one entity, a cult, a following of claymore and now are guilty by association under your premise. Apparently, since I use his miner and have used his miners in the past, I am guilty as well.
it is some of his users, and no need to be rude to each other here
some of his users do act like cult followers, and many of them were bashing linux miners which code of which was in the very miner they were using - that is ignorance...
and his miner was released which cause an incredible increase in hashrate which did drop the price
no need to be ignorant about it.. blame or not, they are the reason the price has had such a steady drop... its just the way it is...
if the truth is annoying,... just don't listen to it
and i did/do like his eth miner, no need to lie about it
but at the same time no need to be ignorant of what happened with the ZCash miner

Thats great claymore included the credit.
what really got me was that his users were using silentarmy in claymores miner but then bashing it and other linux miner zogminer in his thread... and it was going unchecked... that just set me off to be honest.... seemed very ignorant and rude of his users to be doing so. I was a little shocked at first from claymore and his supporters... as I was probably the first person to call out that silentarmy was in claymores miner (even though no one had found the blake2 info yet).
I hope he can continue to share part of the 2.5% fee as the fee is very large, and sharing it will help to continue development of the miner which is at the core of claymores work.
In my opinion he totally corrected any wrong that was originally done, priase to both marc and claymore fo handling this the way they did.
Alot of claymore fans were complaining about it getting removed at first, but it did not have to be removed as was originally stated, only credit had to be given, so I am glad that was done and the miner is once again available for all to use.
Thanks guys! looking forward to future miners from both, interested to see what Claymores V2.2 or V3 with Nvidia support will do in windows
And cant wait for marc's windows release.
I have always been a fan of claymores miners and will continue to be. Thanks again Claymore and thank you Marc.

Then you go on to say how you like his miner but in the zcash forums continue to blame his miner, his alone and him personally, as the reason for the price crash.
You're just annoying at this point.

Claymore copied a part of host code and round0 (blake2b) ? I think, only kernel rounds and solutions extract code is valueble, and it's not copied.

I have to say its amazing to watch this community. For you, mrb, to give your ok stamp on the issue shows your true light. HUGE bow to that.. in this day and age not many would do the same. So far its your code and expertise that has brought the current ZEC community to where it is and I think everybody owes you a TY. The terms of the license don't require any type of monetary compensation, and I don't think its any of anyone's business, however I think most would agree you deserve what you put in. I'm sure an agreement has been made, as it should.
Claymore's miners have always been more commercial (closed source) and typically based off other's base code. Don't get me wrong -- Claymore benchmarks, tweaks, and improves the base code and if I was coding miners I would do the same thing.

and do you get daily cuts of his dev fee? seems unfair if you dont.
You might need to read the MIT license a bit.
"Permission is hereby granted, free of charge, to any person obtaining a copy of this software and associated documentation files (the "Software"),
to deal in the Software without restriction, including without limitation the rights to use, copy, modify, merge, publish, distribute, sublicense,
and/or sell copies of the Software, and to permit persons to whom the Software is furnished to do so, subject to the following conditions..."
If he tried to force a payout on the grounds of the MIT license, it would invalidate the license itself due to the above clause. Honestly, considering the above clause, I'm not even sure why this situation escalated to the point it did. The condition for that clause is simply that the author is credited. Once done, it's free to use/copy/reverse engineer and rebuild. A name wasn't dropped where it should have been, and suddenly the world is on fire. I'm all for credit where it's due, but this is some grade-school chest-beating we're seeing here.
Edited for clarity on the condition of the clause.
It's more a matter of integrity than legality or claiming a licensing fee. An honourable dev does not sell SW he got for free, regardless of the
licensing terms. He should only charge for the value he adds. In this case it's trivial because the value of the copied code was minimal.
November 07, 2016, 08:21:37 PM
and do you get daily cuts of his dev fee? seems unfair if you dont.
Well it's the intent of my choice of the MIT license. I want to allow such uses, at the condition my copyright notice is included.

Let this thread serve as a public record to show that Claymore and I resolved this licensing issue. It is no longer a problem.
Some people ran "strings" on Claymore's Zcash binary and saw function names and variables that matched my SILENTARMY miner: https://forum.z.cash/t/silentarmy-v3-now-a-full-miner-multi-gpu-stratum/3580/629
I confirmed Claymore copied my code beyond doubt: https://forum.z.cash/t/silentarmy-v3-now-a-full-miner-multi-gpu-stratum/3580/641
Because SILENTARMY is released under the MIT license, Claymore was obligated to include my copyright notice, but he failed to do so. So I privately asked him to do so in a private message:
He first withdrew his package from the Internet, then later re-added them with his readme file updated to include the license:
I verified that he added the copyright notice and license as required by the MIT license:
Thank you for doing the right thing. I fetched your new tarball Claymore's ZCash AMD GPU Miner v1.1 Beta - LINUX - Catalyst 15.12.tar.gz and can confirm you included the MIT license as mandated in your "Readme!!!.txt" file, as quoted below.
You are in no way obligated to "pay" me. But if you feel this can help re-establish some of your image and reputation, feel free to publicly send to my donation address t1cVviFvgJinQ4w3C2m2CfRxgP5DnHYaoFC
You are now fully compliant with the MIT license. I hope my SILENTARMY code was useful to you

I had to remove v1.0 and v1.1 from google drive and mega, because I was pointed that I used a small part of mrb's work.
It will take up to 24 hours to revise my code and create own implementation, then I will upload updated version.
Details are:
[mrb's message]
Oh, you are correct, I really missed this point. I was in a big hurry to release first version asap, so I concentrated on main Wagner's algo,
blake is not interesting for me at this point since it takes only 10% of total GPU time and it's trivial in fact, blake algo is not that I can call something new.
But to make some start point asap I included your blake.c into my sources and then forgot about it and did not create my implementation. That's what happens if you are in a hurry.
It is very unpleasant situation for me, I will do the following:
1. I remove v1.0 and v1.1 versions of my miner. In fact, I already removed current packages from google drive and MEGA, I will upload updated versions soon.
In next version I will remove your blake.c from my sources.
2. I apologize, it's only my fault that I used this part of your code. I was not going to do it in public version.
3. I want to send you some compensation from my ZEC dev fee if you don't mind, just send me your ZEC address.
4. I'm not going to hide my fault in any way, I will post this message in my miner thread in first post.

He first withdrew his package from the Internet, then later re-added them with his readme file updated to include the license:
FILES UPDATED TO INCLUDE MIT LICENSE DETAILS IN README.
People started asking me about miner package in PM and some people started to share alternate links for downloading, it's not a good thing because of possible viruses.
So according MIT license I added notice to README and uploaded updated miner packages back to original links. You can also see a license notice in original post of this thread.
