If Bitmain opposed SW because of asicboost, why did it agree with the Hong Kong consensus of SW first and 2M later?

About ""Verified chatlogs: Why Jihan and Jiang want to block segwit at all cost." – WhalePanda"
Chat record, I want to say a few things

1. Source of chat records:
This is a conversation in a public 15-person discussion group that includes all Chinese LTC mining pools and LTC developers. WhalePanda edited a part of it in an attempt to create the illusion that "this is a secret conversation."

2. Controversy about LTC SW:
Our demands have always been clear: implement the Hong Kong consensus, agree to SW first, and then vote on the 2M block one year later.

However, Core opposed the Hong Kong Consensus. After failing to promote SW on BTC, Core introduced the expansion dispute into LTC, attempting to promote SW on LTC first and set an example for BTC.

As I stated in my open letter “Why I Haven’t Voted for LTC’s SW Yet?”:

A mysterious new developer Shaolinfry (I don’t want to guess who he is) appeared in LTC. He was very familiar with SW and helped LTC develop the SW version in a short time. Later, he proposed UASF to BTC as an LTC developer. After UASF was strongly opposed, he proposed UASF on LTC again, trying to use Charlie Lee’s identity as the founder of LTC to force the promotion of UASF.

Our requirements were very simple: SW+ large blocks, and passed at the roundtable meeting. Fortunately, there was no Core on LTC opposing large blocks, so we successfully reached the "LTC Roundtable Consensus".
Everyone can see that this is the Hong Kong consensus of "SW first, then big blocks". This fully proves the broad support of the Hong Kong consensus in the industry . I don't know why Core has been opposing the Hong Kong consensus.

3. What is “greater cost” ?
The next sentence of the dialogue has already given a positive answer:

This will have a direct impact on BTC's soft fork SW activation, a very clear demonstration effect. (This is going to have a direct impact on BItcoin's adoption of Segwit soft-fork, Very clear precedence).

Both sides were vying for this demonstration effect. Core sent Shaolinfry, and we organized the "LTC Roundtable". Fortunately, Core had no reason to oppose 2M. In LTC without Core, the community reached the "LTC version of the Hong Kong consensus".

WhalePanda ignored the direct answer and made a baseless guess that the "greater cost" was asicboost. If so, why did the "greater cost" disappear after the "LTC version of Hong Kong consensus" of "SW first, then big blocks" was reached? This shows that the "greater cost" is the "demonstration effect on BTC" in the next answer, not the asicboost that WhalePanda made a baseless guess about.

4. Regarding the rumor that "Bitmain opposes SW because of asicboost":
The simplest and most powerful rebuttal is:
If Bitmain opposed SW because of asicboost, why did it agree with the Hong Kong consensus of SW first and 2M later?

Then let's talk about technology and logic. The known situation is as follows:
A. AsicBoost requires the cooperation of mining pools and mining machines to take effect <br/>This means that the Antminers currently sold on the market do not have the asicBoost function activated. Anyone can use any Antminer to test in any mining pool, or mine on the test chain where Core has activated SW, and get the same computing power and 110w/T power consumption . Bitmain has not gained any advantage from the sale of mining machines because of asicBoost.

B. AsicBoost theoretically reduces power consumption by 30%, and actually reduces power consumption by 20% (due to implementation costs) Data source <br/>Here, most people have a misunderstanding, thinking that this is equivalent to a 20% advantage. In fact, electricity costs only account for a small part of mining output. Anyone can calculate that according to the current coin price and mining theoretical output, the electricity cost of 0.25 yuan/kWh accounts for 15.36% of S9 mining output, which means that if power consumption is reduced by 20%, the proportion of electricity costs will be reduced from 15.36% to 12.29%, which only increases output by 3%.

Do you feel cheated? Where is the huge 30% advantage you were promised? How come it’s only 3% when you actually calculate it?

The 3% advantage also dispelled another rumor: Bitmain secretly deployed mining machines with activated ASICBoost function in its own mining farms and mining pools. It should be noted that Bitmain is not a secret military organization, but a commercial company. If it were to do anything, hundreds of employees would be involved. Every mine maintenance worker knows that the S9 mining machine in this mine is not the usual 1.2kw, but 1kw, and every mine manager knows that this 3000kw mine is not equipped with 2500 S9s, but 3000.

Bitmain doesn't offer millions of dollars a year to every employee, so how could they keep such a secret? How could they go to such lengths just to gain a 3% advantage?

C. Bitmain supports Hong Kong consensus (SW first, then 2M), and supports EXTBLK (also incompatible with asicboost)
Core likes to say "Bitmain opposes SW because of asicboost", but in fact asicboost is just an unused optimization of Bitmain with only 3% advantage. Without this optimization, Antminer is already the mining machine with the lowest power consumption and has achieved the highest sales.

Bitmain's support for Hong Kong Consensus and EXTBLK also shows that the only thing Bitmain wants is big blocks - which is exactly what Core opposes, even the 2M Hong Kong Consensus. I hope Core can give a clear reason to oppose the Hong Kong Consensus, especially when LTC has already reached an agreement through the Hong Kong Consensus and is moving forward.

Of course, if Core continues to oppose the 2M consensus of the Hong Kong consensus, we are not without solutions. EXTBLK is a solution that can satisfy everyone: it has both large blocks and SW (BIP141), supports lightning networks and rootstock, and is implemented through soft forks.

If you don’t want BTC to split due to Core’s UASF (DASF, Dev Activated Soft Fork) coup, if you want big blocks, lightning network and rootstock, then please support EXTBLK.

The expansion dispute is a very complex issue, involving a lot of technical content, which leads to the first reaction of everyone when seeing this issue: chaos, and no one knows what the two sides of the expansion dispute are arguing about. This lecture uses language that ordinary users can understand to make an objective and comprehensive explanation of the expansion dispute and the views of both sides.
If you have questions about the following:
1. Why did Satoshi Nakamoto set the block size at 33.5M at the beginning and later added a temporary 1M limit?

2. Satoshi Nakamoto gave the plan and code to remove the temporary 1M in the future. What is the reason why Core does not expand according to Satoshi Nakamoto’s plan?

3. What is Core's expansion plan? Why does Core think hard fork expansion is risky? How does the Lightning Network work?

4. Why do the expansionists oppose transforming Bitcoin into a settlement network of "1M+Lightning Network"?

5. What is the root of the disagreement between the expansionists and the Core group behind the apparent block size debate?

6. What kind of compromise process did the expansionists and Core members go through, and how did they eventually part ways?
What are the mutual accusations and conspiracy theories on both sides?

7. Why do the expansionists want a hard fork? What will happen if there is no hard fork?
Why does the hard fork not split into two coins as ordinary users speculate?

8. After the hard fork, what impact will it have on users, miners, exchanges, and wallets, and what measures should be taken?

9. What impact does the hard fork have on prices? What should investors do?
