Let’s talk about the term Fork in Cryptocurrencies!
Cryptocurrencies like Bitcoin and Ethereum work on open-source software called blockchain, where anyone in the community can contribute. Imagine the blockchain as a linked series of data blocks, like cars on a train, with a history tracing back to the first transaction. Because they’re open source, these cryptocurrencies rely on their communities to maintain and develop their basic code.
A fork occurs when a community implements a modification to the protocol, the fundamental set of rules governing the blockchain. This results in a split in the chain, leading to the creation of a second blockchain. This new chain retains all the historical data of the original but embarks on a divergent path.
Significance of Forks – Fork in Cryptocurrencies
Most digital currencies have dedicated development teams responsible for enhancing the network through changes, similar to the way internet protocols evolve for improved web browsing. Forks are undertaken to enhance security, introduce new features, or, in some cases, give rise to entirely new coins and ecosystems.
Soft Fork – Fork in Cryptocurrencies
Conceptualize a soft fork as a software upgrade for the blockchain. Once universally adopted by users, it becomes the currency’s new set of standards. Soft forks often introduce new features or functions at the programming level, maintaining backward compatibility with pre-fork blocks. Examples include enhancements to Bitcoin and Ethereum.
Hard Fork – Fork in Cryptocurrencies
A hard fork occurs when code changes are so substantial that the new version is no longer compatible with earlier blocks. This leads to a split in the blockchain, resulting in the original and a new version adhering to the altered rules. This process gives rise to a completely new cryptocurrency, exemplified by well-known coins like Bitcoin Cash and Bitcoin Gold emerging from the original Bitcoin blockchain via a hard fork.
Difference between Soft Fork and Hard Fork?
A soft fork is a minor rule change still compatible with the old rules, while a hard fork is a major rule change that creates a totally different game, splitting the community into two groups.

Causes of Forks – Fork in Cryptocurrencies
Similar to any software requiring upgrades, blockchains undergo updates for various reasons, such as adding functionality, addressing security risks, or resolving community disagreements about the cryptocurrency’s direction.
Impact on the Crypto Landscape:
In the realm of cryptocurrencies, the Ethereum blockchain is tailored to execute “smart contracts,” which are coded instructions automatically triggered upon meeting specific criteria. Analogously, Ethereum forks, such as Ethereum, Ethereum Classic, and Ethereum 2.0, can be likened to newer versions of an operating system, introducing features or efficiencies lacking in previous iterations.
Soft forks are comparable to ‘software upgrades,’ akin to updating your phone’s operating system, while hard forks represent an entire new operating system, similar to the evolutionary progression from UNIX to Linux and Mac OS. Older and newer forks may coexist as stable platforms or diverge further as they continue to evolve.
