Topic: BS在segwit里有专利，这使过去三年里所有的怪现象得到完美的解释 (Read 221 times)

这篇文章值得一读，尽管只是推测，但中间提及的政治经验，远胜过在技术细节里抓瞎。

One thing that was quite clear in these negotiations was that everybody was trying to get as much as possible of their own patent portfolio into the industry standard, while still trying to maintain a façade of arguing purely on technical merits. Some were good at it. Some were not very good at it at all.
这些（有关电信标准制定的）讨论中有一点是非常清楚的，就是每个参与者都想把具有自己专利的技术埋入新标准里，但又要表现的像仅仅是在讨论技术方案的优劣一样

One of the dead-sure telltale signs of the latter was that somebody would argue that feature X should use mechanism Y (where they had undisclosed patent encumbrance) based on a technical argument that made no sense. When us technical experts in the room pointed out how the argument made no sense, they would repeat that feature X should absolutely use mechanism Y, but now based on a completely new rationale, which didn’t make any sense either.

这种现象的一个很明显的表征就是：有人说功能X需要技术Y来实现（当然Y里包含了他们的专利），但提出的理由不合逻辑。当技术专家们指出这不合逻辑时，他们会坚持功能X确实需要技术Y来实现，但给出了另外一个完全不同的理由，同样也不合逻辑

The real reason they were pushing so hard for mechanism Y, of course, was that they had patents covering mechanism Y and wanted their patented technology to go into the industry standard, but they were unable to make a coherent argument that withstood technical scrutiny for why it was the preferable solution at hand, with or without such encumbrance.

他们鼓吹技术Y的真正原因，当然是因为他们在Y里有专利，希望把带有专利的技术埋入行业标准里，但他们无法给出一个前后一致的说法来说明为什么该技术是必要的



这里顺便说一下，Core所指责的比特大陆因为asicboost而反对SW，属于典型真中夹假的谣言

1、根据Core自己的分析结果，asicboost效果是理论降低30%功耗，实际降低20%功耗（由于有实施成本）

2、电费只占挖矿产出的一小部分。任何人都可以计算，按现在的币价和挖矿理论产出，0.25元/度的电费占S9挖矿产出的15.36%，也就是说如果功耗降低20%，那电费占比将从15.36%降低到12.29%，仅仅提高了3%的产出。

认为比特大陆为了区区3%优势（而不是Core一再宣传的30%优势）而大动干戈，非常可笑。

3、比特大陆支持香港共识，同意在有2M代码的前提下，先激活SW，1年后再投票2M，这就产生了一个悖论：
如果比特大陆因asicboost反对SW，那为什么又赞同先SW后2M的香港共识？

然后又有人说，那时候比特大陆不知道SW和asicboost不兼容，
那不就更简单了？这更说明比特大陆反对无大区块的SW，和asicboost一毛钱关系都没有，仅仅是想要大区块而已。
而BS因为SW专利，以及在侧链开发上的利润不想主链壮大，Core因为BS不想要大区块，这才是关键。
