"THE CODER CODED FOR 10% DEV FEE WITHOUT TELLING USERS--" INCORRECT
"THE PERCENTAGE AND SIZE OF THE DEV FEE WAS NOT REPORTED--" INCORRECT
"And, like I said, the sum of the Optiminer returns (miner net plus dev fee) is still reportedly less than Claymore's Zcash miner net. He charges a clearly stated 2.5% fee." INCORRECT
The crackers say the code is based on SilentArmy. INCORRECT
While I appreciate Optiminer's software, let me comment this from a side point of view.
Plain fact:
the devfee was first mentioned in the README only in version 0.3.1 (0.3.0 and below did not contain it).
Plain fact:
the size of dev fee still is not officially reported.I went to Optiminer after Claymore stopped Linux support. I found the name of the miner and looked at github to try it. I did not look at the source and was thinking that it is an open source (since github was made for open source projects, not binary releases). There
was no mention on github (original distribution source), neither in README, that it contains any dev fee. I was amazed with its performance and even more amazed when I read on forums that there is a dev fee in addition to hash rate shown. I can agree that it maybe was stated on forums, but shouldn't it be stated on the original source site and/or README, at last, if someone concerned about it?
If you look at the github, it contains original README evolved since version 0.1.1. Only in 0.3.2 change was declared "reduced dev fee" - then it was reduced from 15% to 10%. Please take a note that this percent still is not reported and never was in the README or forums by the author, and is the result of evaluation by curious guys.
So while I am not concerned about dev fee exact value, I should confirm that something said by your opponent was correct. I am not on someone's side, but for the true facts.
Talking about competition, at least now the statement is also correct after Claymore's v9 release. It mines at 212-215 Sol/s on my 470 4GB Hynix cards (downvolted, 915W from the wall for rig of 7 cards). Older cards have even better results: 234 for 7970 (and only 185 +10% fee = 203.5 for the same card with Optiminer), 200 for 7950, 312-315 for 390X. Claymore's miner was worse on Polaris vs Optiminer, but seems it is the winner now. At least while 0.7.0 is not released. Still, since Claymore doesn't like Linux, there is no other public alternative to Optiminer yet. Since hash rates were pushed to the top, all have to follow.
