Bitcoin cash (BCH) hard fork before and after situation explanation

BCH Hard fork occurred.

And the difficulty has been fixed, but the https://fork.lol/ site you saw before is no longer meaningful.
This is because the difficulty algorithm compares the hash values ​​of all 144 blocks mined and adjusts the difficulty per block, so the next difficulty prediction is performed in real time.

The reason for the change to 144 blocks is as follows.

• This is the content of the bitcoin in the white paper.
  Bitcoin network is a P2P system. Transactions should be spread to all networks.
  If the network is cut off in the middle and the network is fast only in the United States and the network is slow due to the firewall in China, the transaction of the US will spread only in the US and the transaction will spread only in China.
  If the network between the United States and China is not smooth, the United States and China will keep their bitcoin transactions on their own.
  Then, once the network becomes smoother, the transaction details are verified by mining.
  If there is a problem in this process, the problematic block is discarded.
  If the US and Chinese internet networks are disconnected for 10 minutes, the US and China will have their own transaction history and can cause problems with the bit coin system.
  So I set it to 10 minutes at the first development.

• That is, a day block mining = 144 blocks = 10 minutes (1 block in 10 minutes) X 6 X 24
  As a result, the BCH algorithm has been changed so that the difficulty adjustment is adjusted to 1 block compared to the previous mined hash.

This is before the hard fork.

When one block was mined for six hours, EDA was triggered and the difficulty was greatly reduced. The reason for the EDA was that it gave the miners an economic incentive to recover the chain by securing the city by lowering the difficulty in order to secure the instability of the chain. The BCH inflation was caused by the huge amount of money.

Now let's look at the process before and after BCH's hard fork.

1. Someone pumped the price for a variety of reasons ahead of the hard fork.

2. Since the price was pumped, the diggers obviously increased the hash as they did BCH mining.

3. As the hash has increased, the difficulty of mining has increased.

4. But before the hard fork, the miners' hash moved to BTC.

Of course, you can not be 100% sure of the stability of the hard fork chain, so it is natural to go to BTC during that time.
However, EDA was not triggered because the time to trigger the EDA was cut off because the EDA time was calculated and the price was pumped.

5. The hard fork is up and checks the hash of the previous 144 blocks as described above.

I checked it and of course I ran to BTC, so the hash of 144 previous blocks based on hard fork was decreasing.

6. That's why the difficulty of hard forking has decreased.

7. After the hard fork had been reduced in difficulty because the number of hash has been increased again, the difficulty has been increasingly increased at around 8 pm was quite a state. As a result, I did not know whether it was pumped or pumped, but as a result, the price has risen slightly (5-10%) again.

We will analyze the impact of BCH's hard fork on various relationships with BTC in the future.

It may not be accurate, but you can just look at the big picture.

Thank you. :)
