What is a Blockchain Hard Fork and How It Affects Bitcoin

In software development, a fork or bifurcation is understood as the creation of a project in a direction other than the main or official project through the use of existing source code . This practice is very common in open source or free software projects .

  • What is the Hard Fork in Bitcoin?
  • What types of hard forks or forks do we find?
  • What are the differences between soft and strong forks?

When we talk about forks or forks in blockchains, we refer to the creation of projects starting from a previous project . Therefore, we could talk about a kind of update.

It is important to keep in mind that blockchain networks are governed by codified rules , which allow nodes to validate transaction blocks in the same way and remain in consensus. Therefore, these rules verify that the structure of the block and the transactions included in it, such as the size of the block, that is, the space it has, are correct.

With this little introduction, we are going to delve more about what hard forks are , what types are there and how they work.

Hard Fork in Bitcoin

A fork can be defined as a fork . In programming this refers to the process that is carried out to copy the source code of a program , in this case it would be the bitcoin platform. The forks can be given two different utilities, on the one hand they are used to clone the bitcoin code to create a new cryptocurrency . And on the other hand, to make an update to the existing code .

However, whatever we use it for, as it is an open source system, anyone can have access to the code . Hence, all those with advanced blockchain knowledge can run a fork.

Also, to create a new blockchain project based on the open source bitcoin there are no impediments. But, on the other hand, to update an existing code and implement it in a definitive way, a prior consensus is necessary .

Therefore, having seen what we have seen, we can define the hard fork as an intentional fork with the aim of updating or redesigning the code . This can lead to various results, such as increasing the size of the blocks , or a change in the rules of the system .

Types of Forks or forks

We find several types of forks or forks that we will use for one thing or another, depending on what we want to do.


Soft fork or soft forks

A soft fork is a consensual update of bitcoin’s open source . When we talk about soft, we refer to soft, therefore, it is used to identify when changes in the code do not have an exaggerated impact on the system , and even the result is compatible with previous versions, therefore, they can coexist in the same network bitcoin without problems.

This type of forks are more difficult to implement in code than strong ones , since compatibility with past versions of the software must be taken care of, which adds limitations when programming.

Bumpy fork or strong forks

Crash forks occur when system developers make mistakes while re- forking to repair the errors. This error causes the creation of a second chain of blocks that is based on the new version of the software. Therefore, the blockchain accidentally forks .

Differences between soft and strong forks

In both soft forks and hard forks , users are the ones who must participate in updating the network , either by downloading new software and launching updated nodes, or by abstaining from doing so, if they so decide. However, it should be noted that soft forks do not exclude those who do not update, while strong ones do.

For example, when the forks are used to update the network in question , it is necessary to reach the threshold of adoption by the nodes of the network, previously agreed and implemented in code by the developers of the protocol.


On the other hand, if what you want is to create a new cryptocurrency , consensus is not a problem. The developers of the new blockchain specify the new parameters and a starting point regarding the bifurcated chain. Either zero as happens in the case of Litecoin or a specific block height as in the case of Bcash.

As for hard forks, once these are activated, it is possible to start a kind of market game, which can end in one of the following scenarios:

The old or new chain is left desolate

When the old or new chain is desolate and the remaining ones are active, with nodes and miners mostly migrated to the chain , it is possible that the miners remain in the minority chain or take time to move to the longer ones . If this happens, money is likely to be lost . This is a common scenario when it comes to a scheduled update .

The two chains survive by dividing the value of each cryptocurrency

We find cases in which cryptocurrencies survive, and the processing power and value of each of them is divided according to what the market determines . This scenario usually occurs in contentious or controversial hard forks cases . An example is found in Ethereum and Ethereum Classic.

The chain that initiates the fork is foreign to the main chain

When the chain that initiates the fork is totally foreign to the main chain, it gives life to what is known as altcoin , and this does not necessarily affect the processing power or market value of the original chain.


Therefore, to make a summary and make it clearer to us what the forks of the blockchain are, we must bear in mind that:

Soft forks:

  • They are difficult to program.
  • They lower the consensus rules.
  • Deployment does not imply updating by all nodes on the network.

Strong forks:

  • They are easier to program.
  • Add or change current consensus rules.
  • Its implementation includes a mandatory update of the nodes or exclusion from the network. If you don’t, you can derive to independent strings.

Thanks to hard forks, we will be able to modify our chain of blocks without having to create a new project, since this new blockchain will start from an existing project.

Creating forks is not an easy task, but if you want to learn how to create your cryptocurrencies through the use of blockchains, we recommend our Master in Blockchain and Fintech , with which you will learn how to create a blockchain and a fintech network from scratch. You can now train in the technology of the future!
