1. Prediction of success

exist"

exist"[The righteousness of the world should be mixed into one] (Part 2) Computing power battle", based on my previous experience in computing power warfare, I made a detailed deduction on the various forms and development of computing power warfare. And predict that CSW will not have the determination to fight a frontal war that burns money, but will only fight guerrilla warfare (harassment warfare) that does not burn money.

When two conflicting blocks appeared at the height of 556768, I was still excited, thinking that CSW was planning to fight hard, but it turned out that it was just a normal isolated block: Bitcoin.com and Waterhole dug out block 556768 at the same time, and then Bitcoin.com dug first Out of the next block, the Waterhole block was unfortunately orphaned.

After that, until 11:00 am on the 16th when I wrote the article, no attack occurred, and no attack block was detected.The two sides are just mining on their own chains, there is no frontal battle, no harassment war, not even a single attack, What about the computing power war that CSW has been making high-profile publicity for several months? I am blind to write such a long article analysis.

3. The ratio of martial arts to text

Of course, the whole night was not without interest, but fighting (the two sides attacked each other to isolate each other’s blocks) turned into a text ratio (both sides buried their heads in digging their own chains, and the chain was longer than the other, and the cumulative mining difficulty was higher).

Up to now, the two parties have used a total of 6162P (ABC chain) + 3499P (SV chain) = 9661P computing power, which is equivalent to an output of 13 million yuan per day, and the total amount of pure money burned every day is nearly 10 million.

As a result of the massive computing power of both parties, the ABC chain is currently 42 faster than the SV chain, and the total mining difficulty of the ABC chain is 2.3 times that of the SV.

Note that this comparison is a text ratio. The long chain cannot cover the short chain. It is just that the two parties show off their muscles and show their respective computing power. Because according to the longest chain principle in the white paper, the longest chain (the chain with the highest cumulative difficulty) has a natural orthodoxy, such asBitstamp has announcedTrade ABC as a BCH trading pair.

We will only support Bitcoin ABC during the fork and the price of BCH at Bitstamp will reflect the price of Bitcoin ABC. Initially, we will not support any alternative chains, but will monitor the situation and decide about further courses of action at a later date.

4. CSW Errata

CSW has declared 'no division' for months

Even until a few hours before the fork, CSW was still claiming that "there will be no split"

A large number of fallacies and heresies have been caused, so the special corrigenda is as follows:

1. BCH has separated two chains, BCH ABC and BCH SV. The two chains are completely independent, with different rules and irrelevant to each other, just like BTC and LTC have mutually incompatible rules. ABC longer than SV cannot cover SV, and conversely SV longer than ABC cannot cover ABC.

2. "SV chain includes ABC chain", "SV chain is compatible with ABC chain", "SV chain can be connected behind ABC chain", "SV block can overwrite ABC block" are fallacies, think about it for yourself Can LTC blocks with different rules overwrite BTC blocks?

3、Now the ABC chain produces blocks quickly, but it is only a temporary result of the ABC chain’s large computing power mining. Under the DDA difficulty adjustment, the number of blocks of ABC and SV will be stable at 24*6=144 blocks/day for a long time. Comparing the lengths of the two chains is meaningless, and the cumulative difficulty of the two chains should be compared (cash.coin.dance, etc. are all listed in the cumulative difficulty statistics chart). The computing power of the ABC chain is higher than that of the SV chain, which is finally reflected in the cumulative block difficulty of the ABC chain. 2.3 times of SV.

4、The computing power of the mining pool can be adjusted between BTC and BCH in seconds. There is no such thing as "waiting for the ABC computing power to leave before attacking". The computing power is always there. Now ABC has accumulated a large amount of computing power. In order to obtain the cumulative difficulty & legitimacy far beyond the SV chain.

5. Limiting the maximum block reorganization height (max re-org) is a kind of mining rule, which is a neutral rule that can be used by all parties. It has nothing to do with the "alliance chain" (whitelist mining is the "alliance chain"). max re-org cannot increase the computing power and does not violate the principle of the longest chain of computing power. It just allows the party with the superior computing power to reduce the number of reorganized blocks and reduce the unstable time of the blockchain when faced with harassment from the weaker party. Of course, there is no attack on CSW at the moment, so we can't even talk about reorganization, let alone specific reorganization rules.

BTC and BCH checkpoint codes

Hard fork = open a new chain, so the first block (similar to the genesis block) needs to be determined, otherwise it may cause subsequent nodes to be out of sync. This is not unique to BCH. It is a technical practice formed by early altcoins for hard fork stabilization.

5. The impact of the computing power war on miners

The computing power war is definitely a good thing for miners, because the demand for computing power has increased.

First of all, the two parties mobilized a large amount of computing power to mine on BCH, reducing the computing power on BTC.The next difficulty adjustment directly decreased by 6.8%。

Secondly, both parties may rent a large amount of computing power in the market, raising the rental price of computing power.
