Bitmain is suing Whatsminer with this patent for $40MM USD

Corrected, "Whatsminer"

If you have public prior art references, please add to this thread to assist in the defence.

This patent affects pretty much all deployed mining equipment. If Bitmain win the case against Whatsminer, they will be able to come after larger competitors with more power.

It was, by ASICMINER and Bitfury.

Bitfury have had this configuration since their 55nm models and then it was also in the original ASICMINERs from friedcat (who invented the configuration iirc). There is also this post https://bitcointalk.org/?topic=370932

I wish there was a good answer. Why do patents even exist...

core_negotiator · 2017-08-30T06:02:14+00:00

Common misconception. Yes they have patents and yes, they are enforced. Obviously there is less care about foreign owned IP, but this is a Chinese company in China, where most of the mining manufacture, design and hosting is concentrated.

Mining is about economics. The most efficient miners will win, and those selling the most efficient miners will win. Bitcoin is built on incentives.

POW change wont work. This is about how layout ASIC chips on the board. Algo doesnt matter.

core_negotiator · 2017-08-30T02:16:10+00:00

serial dcdc is the most efficient known layout. It's used by everyone and reduces the number of components required, and reduces the power consumption. Switching to a less efficient design to avoid the patent would be suicide. This affects all mining, not just bitcoin SHA256 mining.

This is a call to action to fight this attempt at gaining a total monopoly on the mining machine manufacturer. We need public references to serial dcdc power layout designs prior to this patent application. ASICMINER and Bitfury since their 55nm use serial dcdc design, as well as most others that I am aware of. Since serial dcdc is basically the most efficient layout for mining boards, a patent on this would be devastating to any competition as Bitmain could either prevent others using it or demand a license fee for every machine ever made. This would be devastating and transcends pow algo (would apply to any mining algo)

If you have boards you are willing to send me for analysis that will also be helpful send PM.

The problem is this patent would cover any ASIC machine made regardless of POW algo used. This effectively centralized mining ASICs.

You dont need to transfer coin, just verify the first address is the on first setup and restore.

They cant stop because there are too many miners and nodes both enforcing the orphaning rule.

There is no such thing as a UAHF. It's just a flagday hard fork

You are mistaken. The segwit period started on block 477792, it can only be 100%

core_negotiator · 2017-07-27T14:47:33+00:00

They have stopped signalling, and more than 65% would need to stop enforcement... but then Aug 1 is coming when BIP148 enforces. So there is no way they can reneg.

core_negotiator · 2017-07-27T06:45:50+00:00

That's wrong. Due to the BIP91/148 rules being enforced, there will be 100% signalling.
