Bitcoin was the first cryptocurrency established when a mystery software engineer going by the name of Satoshi Nakamoto published a program in early 2009. There have been many other digital currencies since then that have been inspired by bitcoin’s success. Many of these currencies make use of Satoshi Nakamoto’s original program and concept technology.
The bitcoin model is by others who modify or seek to enhance upon it. Though they share the same fundamental vision and protocol, various Bitcoin variants differ from one another. Forking is a process that occurs when the bitcoin blockchain diverges in multiple ways. Forking causes a split in the blockchain, dividing it into two separate systems.

Hard Forks in Bitcoin: What You Need to Know
The first block of the bitcoin blockchain was mined by Satoshi Nakamoto in 2009, not long after the cryptocurrency was released. Because it marked the beginning of cryptocurrencies as we know them, this block has become known as the Genesis Block.
While Satoshi initially could make significant modifications to the bitcoin network, this has proven increasingly difficult as the number of people using bitcoin has increased dramatically. Because no single person or organization can decide when and how to update Bitcoin, doing so has become increasingly difficult. It’s possible to create a new part of the blockchain by performing a hard fork on the existing network.
Bitcoin Hard Fork Timeline
The timeline of the bitcoin hard fork is as follows:
- The XT version of Bitcoin
That is one of the earliest significant Bitcoin hard forks when it came to Bitcoin XT. Several additional features offered by Mike Hearn were incorporated into the software when he published it at the end of 2014. Bitcoin XT aims to achieve 24 transactions per second, compared to the previous version’s seven transactions per second.
To do this, it recommended raising the block from 1 MB to 8 MB. 3 In the midsummer of 2015, Bitcoin XT was a big hit, with over 1,000 nodes running the software. 4 However, after only a few months, consumers began to lose interest in the project, and we mostly forgot about it.
- Classic Bitcoin
Some members of the Bitcoin XT community desired larger block sizes even after the network’s popularity waned. Bitcoin Classic was established in early 2016 by a community of developers as a reaction. The block size would be increasing day by day to eight megabytes in XT, but only two in classic. 3 Bitcoin Classic, like Bitcoin XT, had a burgeoning community of around 2,000 nodes for some time in 2016.
Some developers continue to promote Bitcoin Classic, even though the project is no longer active. Despite this, it appears that the majority of the crypto-community has shifted its attention to other currencies.
- Amount of Bitcoins in Existence
Since its launch in early 2016, Bitcoin Limited has remained a mystery. The project’s creators did not indicate what fork was required to run correctly despite releasing code. Bitcoin Unlimited differs from other cryptocurrencies in that it gives miners complete control over the size of individual blocks, up to a maximum of 16 gigabytes. 3 While there is still considerable enthusiasm for Bitcoin Unlimited, it has been generally unsuccessful in gaining support.
- Witness Isolation Protocols
Bitcoin Core programmer Pieter Wuille introduced SegWit (Segregated Witness) in late 2015. SegWit’s goal is to make bitcoin transactions smaller to process more of them at once. Although technically a hard fork, SegWit was a soft fork.
- SegWit2x
When SegWit came into the market in August 2017, they anticipated the protocol update to include a second part. With the inclusion of SegWit2x, the block size would be increased to two megabytes, resulting in a hard fork. 11 In November 2017, a hard fork to SegWit2x was planned.
However, several businesses and individuals therein the bitcoin community who had initially endorsed the SegWit protocol have opted to withdraw from the second hard fork. SegWit2x’s opt-in (rather than required) replay protection significantly influenced the sorts of transactions that that new fork would just have accepted, which contributed to the reaction.
- Cryptocurrency Cash
Some Bitcoin developers opted to start a hard split in reaction to SegWit to escape the protocol upgrades it brought about. The hard fork of Bitcoin that has had the most adoption is Bitcoin Cash. Market capitalization ranks it at number 11 in June 2021 due partly to the support of several notable people in cryptography and numerous popular exchanges. The Bitcoin Cash protocol does not use SegWit and enables blocks up to 8 gigabytes in size.
