The blockchain platform is based on the exact mechanism for updates and improvements. Decentralized applications, such as cryptocurrencies on a blockchain platform, require a separate, more complex methodology. In contrast, centralized network operators can rapidly upgrade their software with innovative elements at the click of a button. A fork is a distinct method of updating or improving a blockchain. Forks are divided into two types based on their function: soft forks and hard forks.

But first, let’s define what a blockchain fork is and the differences between a soft fork and a hard fork.

1. What is a Hard Fork?

A hard fork, also known as a (hard fork), is a radical change to the protocols of a blockchain network. In simple terms, a hard fork divides a single cryptocurrency into two, which results in the validation of previously invalid blocks and transactions or vice versa. Following a hard fork, all developers must upgrade to the most recent version of the protocol software.

This implies that the outdated nodes won’t accept the recently updated blocks, and the new blockchain will operate under new rules that will indefinitely reject blocks from the old blockchain. This is known as a “backward-incompatible” software update.

2. What is a Soft Fork?

A hard fork is a blockchain update incompatible with previous versions, whereas a soft fork is a forward-compatible rule change. The soft fork is a forward-compatible modification, so the outdated blockchain will continue to accept blocks from the brand-new blockchain protocol, even though the rules have changed due to the new software.

Simply put, a soft fork tricks the old blockchain into accepting the new rules and, as a result, takes both the updated and old blocks of transactions. In contrast to a hard fork, a soft fork preserves the old blockchain by retaining two lanes with distinct rules.

Soft forks are another type of fork that evolved from intention forks. Hard and soft forks are similar in that when a blockchain rule is changed, the old version remains in the network alongside the new one.

Soft forks allow old nodes to accept invalid data from new nodes without the user’s knowledge. Nodes in hard forks will stop processing blocks after new rules are added.

Soft forks typically keep the two versions of the software compatible, whereas hard forks do not. While both forks result in a split, a hard fork results in two blockchains, whereas a soft fork results in one.

Because of the differences in security, almost all users and developers prefer a hard fork over a soft fork. Overhauling all of the blocks within the blockchain takes a significant amount of effort and computing power, but the privacy provided by a hard fork is an important differentiator.


Whatever the type of fork, it is clear that much work remains to be done to ensure a smooth transition of blockchain updates and upgrades. Most blockchain miners and buyers favor hard forks because they reduce the risk of validating or mining invalid blocks.

By using hard forks, blockchain miners and merchants are protected from being left behind or duped, especially when they are in the process of running. On the other hand, hard forks consume many computational resources and are considered detrimental to the future of cryptocurrencies.

Despite their inherent risks, soft forks provide a much faster solution to blockchain software upgrades without consuming excessive computational resources. The ability of soft forks to introduce updates without fracturing the community is also praised. Contact us if you are seeking a full-service blockchain development service.
