I bought an S7LN, that's the last new Bitmain miner I've purchased since the S3 days and that was so I could figure out how to hack it. Right now it's providing heat for the crapper at the shop. Figure I'll stick to mining on secondhand gear and stuff I build myself.
Not supporting nefarious actors would be nice. ASICBOOST itself wouldn't be too bad (I mean, it is a good idea) if it wasn't being patented and licensed out. That's pretty counter to Bitcoin philosophy in general. But Biodom, I figured out a long time ago that people who stuck to their ethics are a sore minority in the bitcoin world. People here really like to make money and don't often care how.

don't count on me, so there are at least two of us, hence NOT anyone.
Feel free to split hairs if it makes you feel good
I'll pay a premium, anything to avoid these criminals
No you wont, and neither will anyone else. Thats why the market is the way it is....

The reason it makes me angry is that I consider this practice unethical (not being open about it). I would have hesitated to buy their equipment had I known they do business like this. Their customers should be included in the "optimization".
Agreed and i don't think we heard the end of this story yet.
Lots of posts are floating or reddit re antpool and this feature.
Re btc and altcoins, I agree with Phil that btc mining reputation got damaged by nefarious actors.
It is not individual miners fault per se, but we all share some blame in a sense of unwittingly supporting them.
Personally, I regret buying their equipment knowing what i know now.
Commodity mining, where you don't rely on a single or dominant manufacturer, should avoid such problems.
Phil is just guessing that NVidia and AMD could do something to promote alts.
There is absolutely no evidence that this already happened or will happen in the future.
However, there is clear and accumulating evidence that asicboost/Bitmain screwup did happen in btc space.
So Phil - you're saying you want to mine a coin whose value is being held artificially high as a sales gimmick?
ASICBOOST is a hardware implementation. I wonder how they built it into the S9 in a way that would work with the typical. Maybe if I get time this weekend I'll go back over the whitepaper and refresh on some concepts. If Bitmain was doing something that wouldn't be surprising in the least; those guys really really like profits and don't seem to mind screwing people to get 'em. At least they always deliver the gear, got that going for 'em, but that's about it.

There's also the consideration that coin prices tend to drift toward the average cost to manufacture and there's no reason your favorite altcoin wouldn't do the same thing. And if you're trading your cheaply-mined alts for bitcoins you also have to consider those coins were generated by a miner somewhere getting the short end of the stick.
But anyways, a question about bitcoin mining hardware and protocols can't really be answered by saying "ignore it and mine something else instead".

I agree with Sidehack here, Phil. The better the profitability the more investment in mining the coin = more hash, less profit / miner and the trend towards equalization. This should always occur in any PoW coin as miners will shut off the machines when unprofitable (better to purchase coins), and will never sell their mined coins at < cost to acquire (this also pressure towards equilibrium and also stabilizes price).
Also Sidehack as per your question above, i'm sure you're up to date now, but there's allegations floating around (which appear accurate) that Bitmain has been using covert ASICBOOST, but not disclosing it, and gaining 20-30% efficiency gains. This shines a light on the whole reason they oppose Segwit etc. The reason it makes me angry is that I consider this practice unethical (not being open about it). I would have hesitated to buy their equipment had I known they do business like this. Their customers should be included in the "optimization".
Hopefully someone smart on this forum will post anhow-to guide to get our S9's to run ASICBOOST (I assume the pool would have to enable it + firmware update to the S9?)

nope as there are more then 100 companies with more then 1 trillion in assets that can simply buy some zec or eth or xmr.
this is the factor that is causing the rush to alts.
Take ZEC look at tiny market cap 60 million
it is so easy for a company like nvidia to pump the coin they do it.
this is not true for btc it takes heavy money to pump the coin
look at Nvidia worth more then 59 billion
for them to do a pump of ZEC one or two times a month to sell more gpus is a no brainer a very cost effective commercial.

Does not matter much anymore as the shift to other coins will continue.
Frankly bitmain should get its way with bu and use the boost giving a 20 or 30 percent edge for Thier miner.
This would simply drive mining into alts faster.
The segwit vs bu. is a moot point either one won't stop alt coin growth.
The companies that stand to gain from alt coin growth are many with huge wealth.
Intel,AMD,NVIDIA every mobo builder every ram stick builder every case builder every Psu builder.
ASIC builders can't subsidize btc like the companies above can subsidize alt coins.
This shift is not changing. Do the math on a Nvidia mining Zec power used is 1/4 that of power used with an s9
By power used. I mean this 350 watts earns the same as 1400 watts.
So segwit or bu or ASIC boost does not fix that difference.
See screen the s9 makes 7.86 usd a day using about 1400 watts.
boost it 30% it makes 10.21 usd a day
here is an s-9:
here is a 2 card amd using 310 watts it makes 4 bucks a day so 2x that it makes 8 bucks using 620 watts
3x it it makes
12 bucks using 930 watts
this kills the asic boosted s9 never mind the normal s9

I read that Asicboost is not possible if there is a soft-fork solution to Segwit and that would be the reason why Bitmain would love so much a hard-fork solution like Bitcoin Unlimited for example.
Last I checked, it was a means of paralleling multiple midstates under a single nonce. The most efficient means of generating multiple midstates relied on a change in bitcoin protocol, which is using a zero-padding field as an extra data field. If done right it ends up combining another step (or partial step) of the double-SHA calculation where the efficiency increases slightly the more parallel midstates are used per nonce. I forget the specifics because it's been six or eight months since I read the whitepaper.
I know nothing about the extra nonce operation you're talking about. I wasn't really concerned with chip functions back then.
What's the current Bitmain/ASICBoost fiasco? I seem to have missed that news.

I would like to see how some talented guy will develop a hack which will enable this "asic boost" an all Bitmain HW all around the world...
I will not become a millionaire because of that hack, I'd just like to see what will happen then... And what will Bitmain say...
Of course all those empty blocks generated wouldn't disrupt anything at all aside from increasing the rate of diff increase... I will not become a millionaire because of that hack, I'd just like to see what will happen then... And what will Bitmain say...
Query: Is this ASICBOOST the same idea as the "Golden Nonce" or extra nonce operation that HF and other miners from a few years ago used?

I don't want to jump the gun, I would certainly like to see Jihan / Bitmain comment, but this covert ASICBOOST fiasco has made me completely distrust Bitmain and it's entire brand.
Hey, millionaires around here(and I'm sure there's many) - maybe get together and build some industrial ASIC's for us little guys who want a fair chance? I'll pay a premium, anything to avoid these criminals
