Just a short piece about the differences between two type of devs.

James Hilliard contributed to segwit2x btc1 repo and the effort:

Gregory Maxwell on the other hand:
1) Lies about not being invited to NY meeting:

2) Do whatever he can to harm it:

3) His only “contribution” is around the ASICBOOST-BS-GATE:

Someone send me the following link, putting it here to give a more balanced view on Gregory Maxwell:

I consider myself Core supporter (but I object Core supporters methods).
I want to help hard liners ideological core supporters to set in advance a minimum value for future UAHF coins (what they call “Bitmain Coins” in a derogatory way). I offer to buy, in advance, future UAHF coins for $1…

We found ASICBoost independently in the beginning of 2014. We called it Merkle Collisions and patented it also, but only later. ASICBoost saves about 15% in electricity once you actually implement it in a chip.

If we assume that BitmainTech directly control 500 PH/s (they control less in my estimation) of S9 machines (power efficiency at the wall of about 0.1 J/GH), then assuming they deploy in their data center in Sichuan (sub 0.03 $/KWh), the total annual savings are:

500 / 0.1 X 15% X 24 X 365 X 0.03 X 1,000 ~= $2M

Those numbers are easily verifiable. I believe their claim about not activating ASICBoost. It is very small money for them.
