You should watch your language and be respectful...at least when you use your moderator account.

Obviously anyone opinion is welcome, but better to keep one user account for moderation and another for your own opinions.

No. I only use one account for everything, both for my opinions and when I moderate. It is very clear when I speak as a moderator because the only time I do is when I moderate, and right now, I have not done any moderation action on this thread. Staff members using alt accounts is frowned upon.

I think you have been the only one to mention "asicboost". Do you have any statistical evidence for the possibility you claim?

Reverse engineering has found that the mining chips used in Bitmain's Antminer S9's and R4's (and perhaps more, I don't know off of the top of my head) contain the circuitry necessary for asicboost to work. It was also found that antpool and the publicly available firmware for the antminers contains the codepaths and api calls necessary for overt asicboost to work, and in fact people have managed to get their miners to use overt asicboost. See https://www.reddit.com/r/Bitcoin/comments/63yo27/some_circumstantial_evidence_supporting_the_claim/dfy5o65/

That's not statistical evidence of blocks mined by that procedure.

The entire point of covert asicboost is that it is covert, you cannot detect it and there is no statistical evidence that it is being used. The only evidence you can have for it is to examine the software and hardware being used by the suspected party. So far, the hardware and publicly available firmware has been examined and confirmed to be capable of using covert asicboost. Greg has examined a private software and firmware and confirmed that those software came from Bitmain and that they had covert asicboost implemented. Regardless, there is proof that asicboost (covert and overt use the same hardware) is implemented in production hardware and the overt version can be made to work with production hardware and software. Whether Bitmain is using covert asicboost privately is unknown, but likely given the available evidence.
