blockchain fork what is it and what are the benefits

The hardware, the running device, and all of the packages that enable the networks on which cryptocurrency investments are made require regular updates. This is due to the fact that software development is an ongoing process as technology evolves.

Blockchain development is no different, and both Bitcoin and Ethereum have undergone numerous changes over the last decade, which may result in cryptocurrency forks.

Blockchain networks are governed by guidelines codified within the protocol that allows nodes to validate blocks of transactions in the same way and maintain consensus. These guidelines ensure that the shape of the block and the transactions contained within it, as well as the block size (quantity of available area), are correct.

Sometimes the consensus guidelines are changed to include updates or protect the community from attacks or modified for specific purposes, such as introducing a new cryptocurrency.

What is a Blockchain Fork

Forking refers to the process of updating a cryptocurrency protocol or code. As a result of the fork, a chain of blocks is divided into branches. This can happen when community members cannot agree on the consensus algorithm (unanimous on the future state of the Blockchain) and new rules for validating transactions.

A fork in software development is the creation of a unique program from the main or legitimate program from the supply code of the current one. This exercise is frequently used in open supply or free software tasks. Forks are used in Blockchain networks to create new tasks that start from a previous one and replace a project.

Types of Blockchain Forks

There are two types of forks: soft forks and hard forks.

Soft Forks

A soft fork is a software upgrade compatible with previous versions of the software. This means that individuals aren’t required to update the software to continue participating in transaction validation and verification.

Implementing a soft fork is much easier because it only requires the majority of people to replace their software. Everyone, whether or not they’ve completed the update or not, will continue to learn new blocks and maintain their compatibility with the community.

However, skipping the update has a negative impact on miners’ capability. A soft fork would be the implementation of a brand-new rule requiring a block length change from the current 1MB (1,000KB) to 800 KB.

Participants who avoid the update should save to validate new incoming transactions. In the process of mining new blocks, the community could reject the blocks (and thus the work) of these miners who had updated their software.

As a result, soft forks constitute a slow update mechanism, the goal of which is to encourage people to execute the update to no longer see its functionalities reduced.

Hard fork

A hard fork is a software update that is incompatible with previous versions. As a result, in order to continue collaborating and validating new transactions, it would be necessary to upgrade to the latest version of the software.

Those who reject the update are disconnected from the network and can no longer validate new transactions. This split causes the Blockchain to diverge indefinitely.        

As long as the minority chain maintains support – that is, there are still people mining on the said chain – the two chains will coexist. (Examples include Ethereum Classic and Bitcoin Cash.)

Examples of Forks

  1. Bitcoin Cash (BCH)
    Because no BCH crypto pockets could be given bitcoin transactions and blocks, the BCH foreign money became separated from the main bitcoin Blockchain in August 2017. Compared to bitcoin’s 1 MB block size, BCH allows an eight-megabyte block size for faster transaction processing. BCH can process transactions faster and handle more transactions than the bitcoin network, but one minor issue is the risk of security breaches due to the longer block length.Furthermore, Bitcoin remains the world’s most important cryptocurrency based on market capitalization, so BCH customers may find its liquidity and value lower than bitcoins.
  2. Bitcoin Gold (BTG)
    In October 2017, BTG forked from Bitcoin. The new algorithm BTG used an algorithm that produced equality among all bitcoins. BTG is available on 40 cryptocurrency exchanges and in 11 different coins.It is also compatible with cryptocurrency wallets such as the Ledger Nano X and the TREZOR one hardware wallet.
  3. Bitcoin XT
    Bitcoin XT changed into one of the first fundamental bitcoin forks. Mike Hearn launched the software program in overdue 2014 to deal with a few new functions he had planned. First of all, Bitcoin XT did well, with over 1,000 nodes strolling its software program via way of means overdue summer season of 2015.
  4. Classic Bitcoin
    When Bitcoin XT fell in value, some public members continued to advocate for larger block sizes. In response, in early 2016, a group of developers launched Bitcoin Classic. Unlike XT, which proposed increasing the block length to eight megabytes, Classic intended to increase it to just two megabytes. Bitcoin conventional, like Bitcoin XT, saw preliminary interest, with around 2,000 nodes over several months in 2016. The project is still active today, with a few developers strongly supporting Bitcoin Classic. However, the cryptocurrency network appears to have moved closer to general options.
  5. SegWit2x
    When SegWit was completed in August 2017, the developers proposed the second component of the protocol update. This enhancement, known as SegWit2x, may inspire a hard fork requiring a 2-megabyte block size.In November 2017, SegWit2x was announced as a hard fork. However, a few businesses and individuals on the bitcoin network who initially supported the SegWit protocol decided to revert the hard fork into the second component.Some backups resulted from SegWit2x, including (rather than required) replay protection; this will have a significant impact on the types of transactions that the new fork can accept.

How do Blockchain Forks work

A fork in a Blockchain can occur on any cryptographic technology platform, not just Bitcoin. This is due to the fact that Blockchains and cryptocurrencies operate in the same manner regardless of the crypto platform they are on.

There are also two types, as previously stated. Consider the blocks contained within the Blockchain as cryptographic keys that flow memory. Because miners on a Blockchain set the guidelines that flow reminiscence across the community, those miners recognize the brand-new guidelines.

A hard fork is a complete change within the protocol of a Blockchain community that results in two branches, one following the vintage protocol and one following the brand-new version.

However, all miners must agree on the new guidelines and what constitutes a legitimate block on the chain. So, while you must change those guidelines, you must “fork” it, like a fork in the road, to indicate that a change or deviation from the protocol occurred. The developers can then update all software to reflect the new guidelines.

Many virtual currencies with similar names to bitcoin have emerged due to this forking system, including bitcoin cash, bitcoin gold, and others.

Why do we need Forking in Blockchain?

We need to fork in Blockchain for the following reason:

  1. Security updates: Forks can be used to improve network security and address flaws in the original Blockchain, which is why many think forks benefit cryptocurrencies. Investors now have more options for diversifying their portfolios, especially in the case of hard forks, where new forms of currency are created.
  2. To prevent emerging cyberattacks on the current Blockchain.
  3. To improve functionality by updating the software.
  4. Forking is paramount when there is a disagreement between developers regarding the protocol.
  5. Forking in Blockchain becomes paramount when there is a move by the community and developers to reduce the potential of crypto miners.
  6. To curb and truncate an attempt by developers to invite multinationals to enforce regulatory measures.

What are the benefits of Blockchain Fork

Most digital currencies have unbiased development teams in charge of editing and improving the network, in the same way, that changes in Internet protocols allow net surfing to improve constantly.

As a result, forks occur regularly to make a cryptocurrency more stable or include new features. However, developers of a brand-new cryptocurrency can use a fork to create entirely new currencies and ecosystems. So, we can rightly say that due to the fork, so many digital currencies have emerged.

How do Forks affect crypto price

User groups frequently oppose hard forks because doubling their currency will unavoidably devalue it, it’s far less desirable competition, and all of the disruptions will affect the prices.

However, this is not always the case in practice. In most cases, a successful fork ends up being fantastic information for investors. And these are some of the ways forks can affect crypto prices:

  • News of an upcoming fork airdrop and new coin regularly causes a buying frenzy, driving up prices.
  • If public opinion is overwhelmingly opposed to the new forked coin, customers will frequently use it to purchase more of the old coin. This could push prices even higher. User groups frequently oppose hard forks because doubling their currency will unavoidably devalue it, it’s far less desirable competition, and all of the disruptions will negatively affect prices.
  • If the coin becomes valuable in its own right, the users/holders who held on to it were genuinely given free money.

How do Forks affect the cryptocurrency landscape?

The Ethereum Blockchain is intended to carry out “smart contracts.” These lines of code execute a predetermined sequence of moves while certain criteria are met. Smart contract packages cover various topics, from video games to logistics equipment.

The Ethereum Blockchain serves as the platform for those applications. Consider it to be similar to a computer operating system. Using this analogy, the unique forks of Ethereum (Ethereum, Ethereum Classic, or Ethereum 2.0) could represent more recent variations of a working system, which upload capabilities or compensate for the shortcomings of preceding variations.

An older fork can still be a solid and effective platform, whereas a more recent one can provide developers with entirely new ways to interact. (Old versions may merge with new ones or evolve on their own over time.)

For starters, consider soft forks as a “software program substitute” (much like what occurs when you update your smartphone by replacing the former model of the working system with the current one).

On the other hand, hard forks may constitute an entirely new working system (simply as Linux and Mac OS are the evolution of the half-century-antique UNIX platform).

What to do before, during, and after a Fork

If an exchange or wallet brings up a newly forked coin, it will usually freeze transactions before and after the coin is onboarded.

As a general rule, you should avoid buying and selling at some point in a high-quality fork:

  • Do not conduct any transactions with a newly forked currency until it is deemed safe and functional.
  • Use extreme caution when downloading the new wallet to accommodate a forked coin. As a rule, you should no longer believe a wallet or forked coin that isn’t open supply and hasn’t been thoroughly examined by means of different people.

The effect of Fork on the user

A cryptocurrency’s breakdown no longer implies that you will lose your digital money. After copying the Blockchain, you retain ownership of a cryptographic key in your wallet. The new currencies allow you to transact unless you use an intermediary or third party to apply.

Following a hard fork, all owners of the original currency receive the same amount of the new currency. This does not, however, mean that the value of the currencies you keep has doubled.


Soft forks are a significant step forward for a generation that is still in its early stages. On the contrary, hard forks are typically encouraged by disputes among developers and this result in the division of project, which isn’t always effective at all.

Being a decentralized technology, the conflict of egos creates circumstances in which precedence is given to personal or business interests rather than technological progress. A coin created through a hard fork appears to be created by a group of people who have strayed far from the original concept of a specific cryptocurrency.

If funding a digital property is already a high risk in those cases, this risk is magnified. Therefore, investors need to thoroughly research before investing in a new cryptocurrency emanating from forks.
