some clarification on those "facts":
1. Jihan supported before understanding the final SegWit Implementation code.
2. Extension blocks do not change the Coinbase references, only add new anchor txs.
3. This comment is jumping the gun. In depth investigations begin now.
4. This data set should be larger and go farther back in time. Likely prior to the patent dates.
The ASICBoost could be throttled from time to time to prevent obvious indicators.
5. Fees are irrelevant here. The exploit centers around gaining more block rewards.
In a future with less block reward and more fees, this exploit is worthless.
6. We need independent verification, which will begin now.
so your saying they did go back in time and made S9chips to include asic boost to attack segwit..
wow amazing.
or logic dictates that segwit wasnt programmed well to actually work with asic efficiency boosts.
Hint: which is easier
1. go back in time by 2 years and undo hardware changes to meet temporary software requirements just 6 months ago, just for some blockstreamer
2. get the centralist blockstream team to now change their code seeing as its only been in public for 6 months and not even active code yet
calling an efficiency boost an attack, even though the efficiency boost existed prior to the code that is supposedly being attacked.. has been the funniest twist of words by greg this month.
anyway
...
Bitmain in their recent statement admitted that there chips have ASICBoost
built in, but have not used them on the main chain. Are you calling Bitmain
timetravelers then? Obviously not. This means they had them for a longer
time than people assumed.
When SegWit was released, Bitmain and it's pool, Antpool, did not yet know
that the Coinbase reference is added to with anchor codes. When they learned
it did, they likely began to oppose SegWit on those grounds secretly but
declared publicly it was because there would be no 2MB blocks.
This is a reasonable premise and is being investigated.
If Maxwell is a liar or spreading FUD as you and Bitman believe, that will be
determined in time. All things come out in the wash in time.
