Bitcoin Cash (BCH) was created through a hard fork of the Bitcoin blockchain. A hard fork is a permanent change to a blockchain's rules that makes the new version incompatible with the old one.
Here's how Bitcoin Cash was created:
1. Developers changed Bitcoin's software.
They modified the Bitcoin code to increase the maximum block size from 1 MB to 8 MB initially (it was increased further in later updates). Larger blocks could include more transactions.
2.The new software was released.
Miners and node operators who agreed with the changes installed the new software. Those who preferred the original Bitcoin rules continued running the original Bitcoin software.
3. The blockchain split
On August 1, 2017, at Bitcoin block 478,558, the network divided into two separate blockchains:
Bitcoin (BTC) - Continued under the original rules.
Bitcoin Cash (BCH) - Began following the new rules with larger blocks.
4. Balances were copied.
Because both blockchains shared the same history up to the split, anyone who owned 1 BTC before the fork also owned 1 BCH on the new Bitcoin Cash blockchain.
A SIMPLE ANALOGY
Imagine a group of people writing in the same notebook. One day, they disagree about the rules. One group photocopies every page of the notebook and continues writing with new rules, while the other group keeps writing in the original notebook. Both notebooks have the same history up to the split, but after that they become completely independent.
WHO CREATED BITCOINCASH (BCH)?
Bitcoin Cash was created by a group of developers, miners, businesses, and supporters who wanted Bitcoin to handle more transactions directly on the blockchain. Early supporters included people such as Amaury Séchet, who developed the Bitcoin ABC software, and Roger Ver, one of the cryptocurrency's most prominent early promoters.
In short, Bitcoin Cash was created by copying the Bitcoin blockchain's history and launching a new network with different consensus rules, allowing it to evolve independently from Bitcoin from that point onward.
