Why Hard Fork a Blockchain

Why Hard Fork a Blockchain
5 min read

Bitcoin was divided into two coins in the summer of 2017: bitcoin (BTC) and bitcoin cash (BCH). A hard fork is what's known as a split like that, and later that year, more forks appeared using blockchain development company.

A hard fork (or hard fork) is a major change to a network's protocol about blockchain technology that makes previously invalid blocks and transactions valid, or vice versa. After a hard fork, every node and user must update to the most recent protocol version.

Understanding Fork

When the majority of blockchain users cannot agree on an upgrade, a fork in blockchain results. Hard forks have occurred in a number of blockchain/cryptocurrency networks, including Bitcoin and Ethereum, as a result of disagreement over polarising software upgrades. 

One can distinguish between accidental and purposeful forks. Accidental forks occur when two or more blocks are discovered at once. They are resolved when new blocks are added and one of the chains becomes longer than the other.

Intentional forks, or the second class of blocks, come in two varieties—hard forks and soft forks—and modify the blockchain's rules.

Understanding Hard Fork 

A hard fork is a rule modification that has significant effects on a blockchain network's whole protocol. A fork can be made by the developers of a blockchain or by users in the community.

All nodes intended to operate following the new rules must update their software because, in comparison to the old rules, valid blocks produced using the new rules may be viewed as invalid or invalid blocks will be viewed as valid. 

Since a hard fork permanently diverges from the prior version of the blockchain, it effectively creates a brand-new currency. The new, improved blockchain will be followed by a new path and the old path by the other. The users of that specific blockchain have the option of upgrading and taking one path, or not upgrading and continuing on the other. The term "backward-incompatible" describes this.

Reason to Hard Fork a Blockchain 

Add New Functionality 

The Blockchain code is upgraded regularly. People from all around the world construct public blockchains because the bulk of them are open source. The improvements and issues are created, resolved and new versions must be released when the time is suitable.

Address Security Issues

Compared to traditional money (notes, coins, and checks), blockchain (and cryptocurrency on top of it) are relatively new technology. And research is currently being done to properly comprehend them. New versions and updates should be made available to remedy the security flaws that emerge during the process.

To Reverse Transactions 

If the community discovers that a certain period's transactions were compromised and malevolent, it has the power to nullify them all.

Some Instances of Hard Forks

Since the launch of blockchain technology with Bitcoin in 2009, there have been several notable hard forks. Think of Bitcoin as an illustration. 

In 2014, when Bitcoin XT split apart from Bitcoin, it underwent one of the first hard splits in history. A suggestion was made to enhance Bitcoin's maximum transaction rate from seven to 24 per second. To do this, each new block's size was increased from one megabyte to eight. The Bitcoin XT project, however, lost interest quickly after the fork and is no longer in use. 

Following the failure of Bitcoin XT, a new proposal to increase Bitcoin's block size was made. Another hard fork occurred in 2017 and gave rise to the new cryptocurrency Bitcoin Cash (CRYPTO: BCH). A hard fork in Bitcoin Cash occurred in 2018, resulting in the creation of Bitcoin Cash ABC (the original version) and Bitcoin Cash SV (CRYPTO: BSV), a brand-new parallel network.

For the bitcoin development industry to advance over time, hard forks are essential. They spread in popularity over time and make sure that the crypto industry develops following community opinion. Good coins like Litecoin or Bitcoin Cash have emerged from numerous hard forks. Therefore, in the long run, these forks are crucial for better crypto offerings. The key is to conduct research before investing.
