Well, well, well, now we know what Jihan Wu’s been up to.

[FiendCoin]

Apparently, Jihan Wu has been covertly using some patented exploit called asicboost to gain 20%+ efficiency on his hardware that’s incompatible with SegWit. It all makes sense now. Hope he gets his ass sued off.

Shills care to chime in?

So far it's been crickets from Roger, Jihan and the shill army. Hopefully this is the nail in the coffin for these bad actors.

[manselr]

That's something I would expect from Jihan Wu, such a sneaky weasel. Im sure Roger Ver knew about this too and they were all profiting from this. BU was obviously a way to keep segwit out of the picture. Bastards!!!

[FiendCoin]

Now we know why he has been blocking SegWit. There's a battle a brewing on r/btc over this very topic. Hopefully, more people will open their eyes.

I knew there was something more going on than just blocksize.

WOW, that is one hidden motive against segwit revealed. I wonder how the community will react to this? One man holding up development of Bitcoin to further his own personal agenda (and wallet).

This also puts other miners at a disadvantage such as Bitfury, I bet there're pissed hearing this 

[FiendCoin]

Still nothing from the shills? Come on guys, I want your opinions 

[jonald_fyookball]

FUD.  Asicboost been known about for a long time and Bitmain holds the patent in China.

Fucking over everyone using bitcoin is great... Potential user sees a group that's able to game the system with an advantage, and want's to run the other way. Was it illegal, who knows. Amoral, unethical, fucked up central banker shit absolutely.

Well I would agree that given the context of Bitcoin that everyone should be able to compete fairly, a patent should be unenforceable, but I wouldn't blame Jihan for trying to mine.  Everyone using ASICs is trying to gain an advantage.

Ridiculous imo to try to change the PoW... its the last thing Core should be doing. 
If Core tries this, there will be a network split guaranteed.

[BitcoinNewsMagazine]

tl;dr for someone just learning of the controversy. Please correct if I make any factual errors.

Greg Maxwell discovered by reverse engineering that a Bitcoin ASIC manufacturer had implemented in hardware a covert, hard to detect version of the AsicBoost algorithm developed and patented by Timo Hanke. Proprietary software is needed to take advantage of the hardware boost and can result in an energy cost savings of up to 30% which is a huge advantage over competitors. Kyle Torpey claims that the ASIC manufacturer is Bitmain.

The covert version of AsicBoost is hard to detect but would explain the odd behaviour of mining empty blocks by Antpool. The improvement in energy use is countered by SegWit, which could explain why Bitmain has been so opposed to adoption of SegWit: it would neutralize the competitive advantage they have from their covert use of a patented technology.

The whole BU drama appears to be nothing but smoke to allow the manufacturer (Bitmain?) to enjoy an unfair advantage over the competition for as long as possible. Greg Maxwell is working on a BIP that would render the advantage useless. 

[gentlemand]

Aren't we constantly being told that seething miner greed is to Bitcoin's advantage?

I've never quite been able to figure out why, it seems painfully obvious to me that individual advantage isn't going to automatically align with the greater good, but that's beyond my pay grade.

your link looks fishy no hostname? whatever
They Patented this?
so only they can produce chips with this hack-like-optimization?
we knew about this for how long?

Still nothing from the shills? Come on guys, I want your opinions  

BU shill here.

this is the free market at work... if you want to mine less effectively go ahead and mine with your CPU.
Its ALMOST as if they created a new chip that simply mines bitcoin more effectively and all of you are like WELL THAT'S UNFAIR!

Yup. Now everything is clear and now we know why everyone must buy LTC.

FUD.  Asicboost been known about for a long time and Bitmain holds the patent in China.

https://www.asicboost.com/patent

All ASIC manufacturing will be in China.

Sorry Bitcoin will never get SegWit nor LN, because Bitmain will block it on Bitcoin. And the whales of Bitcoin will always block larger blocks for the reasons I have explained else where.

But Bitmain is unable to block SegWit on Litecoin, even though they tried to.

Now we know why the other ASIC manufacturers are not against SegWit. They don't want to pay patent fees. Perhaps Baron Wu offered some deals to some others to get them to join his efforts.

Press Release
March 25, 2016.
 
A breakthrough invention in Bitcoin mining named AsicBoost allows to improve the total cost of hashing  20%. The patent-pending invention by Timo Hanke and Sergio Demian Lerner is applicable to any type of chip design for Bitcoin ASICs.
 
AsicBoost is a patent-pending method to improve the efficiency and cost of Bitcoin mining by approximately 20%. Through gate count reduction on the silicon AsicBoost improves two essential Bitcoin mining cost metrics simultaneously and by a similar factor: the energy consumption (Joule per Gh) and the system cost ($ per Gh/s). With the system cost being proportional to the

Note to miners: We, the core devs, discovered a patented optimization in your ASIC. We will make it obsolete in the next update. Thank you.

[iamnotback]

Now that Jihan and Bitmain have been outed as exploiting a vulnerability in Bitcoin's PoW and that SegWit would have made it impossible for them to continue exploiting this vulnerability the motivations for blocking SegWit and supporting BU have now become very clear. We're going to see a shift in SegWit support in Bitcoin very soon and LTC is also helping here by activating SegWit first. I can see some more room up for Litecoin until around 0.02 or $25, but this will change as soon as Bitcoin starts to make progress towards activating SegWit as well and people start moving back into BTC. If you think BTC will stay behind and never activate SW or LN you are sorely mistaken. Let's see what happens and see who turns out to be right.

We can't get 95% to activate SegWit on Bitcoin without Bitmain's approval. They have every right to protect their patent's value. Those who think Bitcoiners will rally to fight him are socialists and communists, who deny capitalism, game theory, and economic reality.

We can't lower the 95% threshold for Bitcoin, because it will cause too much risk and wild price swings.

Also we shouldn't be putting such experimental shit on Bitcoin. Bitcoin is supposed to remain reliable.

Sorry Bitcoin will remain unmodified, as Satoshi (aka Nash) intended its equilibrium game theory to be a clusterfuck of politics insuring the immutability of the protocol which is what gives Bitcoin its trust and value.

wait...
if his asicboost is rendered invalid, doesn't that make all his ASIC+asicboost hardware useless ( totally useless) ?

[iamnotback]

As I understand the whitepaper, yes it would because the logic gates for avoiding the optimization have been eliminated which makes it 20% more efficient.

All those who own Bitmain hardware for mining SHA2 coins, must fight SegWit.

oh this shit is unreal!
EXTRA EXTRA
SegWit turns millions of dollars worth of hardware into bricks.

so what's the risk in forking

we can fork and there's no chance all this hashing power can be used against us.

Having an exploit and using it is one thing. Especially when that thing is a sizeable advantage. But an entirely different thing to manipulate the environment, in order to maintain that advantage. You should evolve, not.stagnate everyone else.  I hate this about DC politics, hate to see it in BTC as well
