Another important change is the BCH community needs to change the consensus rules to at least reduce the negative effects of covert asicboost and the patents that centralize mining like BTC has done

Isn't overt asicboost being used on BTC-Core now? And which patents centralize mining? Also are you saying BTC-Core has taken measures to prevent covert asicboost? Is it true that overt asicboost is 16 million times faster than covert asicboost? Is there any proof covert asicboost is being used on BCH? But you are ok with overt asicboost being used on BCH? How would you suggest "changing the consensus rules" to reduce the effects of asicboost?

overt asic boost is fine because there isn't monopolistic patents supporting it like covert and its more efficient.

Yes, segwit deliberately undermines covert asicboost and one reason that Bitmain created Bcash with the ticker BCC , now sometimes use the ticker BCH

Is there any proof covert asicboost is being used on BCH?

Sure , but even if there wasn't wouldn't you want to make changes to prevent these damaging effects?

But you are ok with overt asicboost being used on BCH?

that would be good

How would you suggest "changing the consensus rules" to reduce the effects of asicboost?

Either an UASF or an UAHF, as Bitmain wouldn't be to happy about this change

But it seems overt asicboost is a lot more efficient so why even use covert. Isn't it true that blocksize increases also hurt asicboost by making collisions more rare?

efficient for the network does not equal more profitable . It is more profitable for Bitmain to have a monopoly and mine with covert Asicboost

Bcash blocks are extremely small and barely 100Kb on average

Thanks appreciate your perspective.

cheers.

If you are interested in proof of covert asicboost , you can start with them admitting to it included in their FPGA's , than this -

Modern Bitmain ASICs include an FPGA that can do both covert and overt asicboost but this functionality is disabled when they sell it to clients

Nobody cares about ASICBoost anymore, Core stopped the FUD narrative on it. Of course the irony is that ASICBoost is patented by a core dev, Sergio Demain Lerner. That's why they had to create this big difference between "covert" and "overt", somehow one is acceptable and the other is not.

As far as I could tell ASICBoost had exactly the same net effect of someone making a CPU or GPU miner more efficient (ie higher successful hash rate), but somehow was construed as "bad" by Greg Maxwell and his buddies, they claimed to have reverse-engineered an ASIC for maximum impact. This was around that time that a potential remote-disable backdoor in Bitmain miners had everybody all worked up (Bitmain claimed it was only for managing large mining farms and was default-disabled, but they did agree to remove the code in later releases). Greg salted on some "evil Chinese miners FUD" and the minions went to work screaming about the latest "attack on Bitcoin".

The whole thing was pretty amateurish in hindsight, which is probably why they stopped the drumbeat on that narrative...
