What Is Immutability?

In this article, we shall discuss the topic “What is Immutability?”. Also, we will relate it to immutability, blockchain immutable, how is immutability achieved, benefits of immutability, etc.

ImmutabilIty is a state of data not being altered or changed.

Meaning Of Immutability

When talking about immutability in cryptocurrency, we are referencing blockchain. To be immutable means no one is able to alter or change data after it is made.

The immutability of blockchain networks is very vital for the validation of data. Also, there won’t be an incessant alteration of records on the blockchain. These records can be in form of contracts, sales, purchases, etc.

The Immutability Of Blockchain

The immutability of blockchain is from a special feature, known as cryptographic hashing. One will ask, what is hashing?

However, the word hashing is a way of protecting any material through the reconfiguration of plain text. This reconfiguration is done into a different hash value. It’s important to note that, the length of hashes is definite.

Carrying out hashing offers both an easy and stressful side. For instance, the implementation of SHA-256 hashing algorithm to the characters “the fast dog ran over the fat cat”, gives “9e107d9d372a5dcea0c3f78f5340d8d4”. To sum it up, to achieve credible data, make use of hashing.

Hashing serves as a digital signature. Also, its value serves as a fingerprint of data. This way verification and authentication can be done on the same data. If there is any contradiction, that means, someone has made an alteration to it.

Importance of Immutability

High security, data integrity, easy auditing, and fraud prevention on blockchains are all important to immutability.

  • The good thing about blockchain immutability is, that the nodes need to agree to perform an action. Any alteration will cause the nodes to readjust to accommodate that change. But, this doesn’t affect the data and records on the blockchain.
  • There is a high safeguard of data integrity. It is important to ensure that the hash value is consistently under calculation. This will authenticate the integrity of data. If they notice any irregularities, that means someone did tamper with the transaction. Therefore, it becomes invalid.
  • Also, a company’s functionality can improve with immutability. What it does for the company is to provide a competent ledger. With this, the company is free from any audit issues.

More Information On Immutability

If blockchain and digital assets like bitcoin weren’t immutable, many corrupt activities will consistently occur. Anyone can have access to records and falsify them.  On the other hand, immutability influences the process of audition. It makes audits very effective by making their time cost-effective.

A company can keep a credible documentary of its transactions and activities. Disputes can be resolved, evidences can be produced. All these are all that immutability can do.

Just like we said earlier, immutability doesn’t mean you are safe from attacks. A major attack on the hash rate creates a major problem for the network. This could lead to an attack known as a 51% attack. Consequently, it affects new and reverses transactions. In Bitcoin, it could be very exhausting to secure much hashing capacity. Also, it will require more resources to take possession of the hashing capacity.

On the other hand, there are networks that are prone to attacks. For instance, the Proof of Work network. This is because it records a minimal hash rate.

Accomplishment Of Immutability

Overview Of Cryptography and Hashing

  • Basically, hashing just has to do with the reconfiguration of data into another form. This current form now serves as a digital signature.
  • In a situation of two file inputs, and a disparity from one byte, the resultant product will be two full strings. The avalanche effect is responsible for this. That is why it is important to be careful while inputting values. Any mistake affects the output. However, there are speculations that the NSA is responsible for the building of SHA-2 and its associate.
  • When carrying out a hash, you ought to be careful. This is because, once there is an output, you can operate on it going back to determine the input. Most importantly, the combination of cryptography and blockchain hashing results in immutability.

The metadata, containing the hash result of the block worked on before, makes up the new block. This connection solidifies the security of the data in a blockchain. Now, the new blocks ward off any form of alteration to the data. Meanwhile, this feature is only unique to blockchain and not to other basic databases.

All the records, data, and information of transactions are in the blockchain. In terms of Bitcoin, it contains transactions between wallet addresses.

Explanation Of Immutability Benefits.

I believe we have seen the importance of immutability above. But, let us still throw more lights on it.

High Data Integrity

How does immutability, give high data integrity?. The movement of data and its activities are all in a ledger in the blockchain. Once they -ascertain the block hashes, they validate the chain’s integrity.

Simplified Auditing

Efficient auditing shall happen once a credible ledger is made available. So, it is important to ensure that nothing happens to the data. Some examples of the use cases are supply chain management, finance, and identity management.

High Efficiency

A credible and indisputable data engineers good analysis and enhances business functionality. A perfect example is the FlureeDB. It made use of the idea of time travel to propagate its business. Also, this application is time and cost-effective. All activities that may be performed like backup and restoring database state are well programmed. That’s the beauty of immutability, as most data issues have become less of a problem.

Proof of Fault

The immutability of blockchain creates room for presenting evidence. For any activity done on the blockchain, it saves it. This evidence can be based on transactions, work, or any form of business. So, at any point of conflict or dispute due to a fault, the blockchain produces the evidence. Because it is immutable, its evidence or information is undisputable.

Benefits Of Blockchain

The most predominant benefit of the blockchain is its ability to withstand data changes. If any source alters the data, the blockchain goes down. This is unlike like normal databases where anyone can alter the data.

Many people have this misconception about blockchain, that no one can alter its data. That is wrong. It can only prove difficult but that doesn’t mean it’s impossible. However, note that this innovation has its pros and cons as regards information security.

Future Purposes

The IIT-B has come up with upGrad. It procures courses relating to block chain in it. With this development, it is beneficial both for personal and technological purposes. Also, you can get access to experienced personnel who can impact knowledge.

With the way blockchain technology is growing, it will soon gain worldwide application. That is why everyone needs to key in knowing more about the blockchain. That is why we recommend ‘upGrad’ for learning purposes. Some of its courses are cheap while some are free.

We cannot over-emphasize the importance of blockchain. It offers a whole lot of qualities that aid the use of digital assets and platforms. On the other hand, companies and organizations can securely verify and transfer information around. Its value also cuts across maintaining financial structures. This and others are the importance of blockchain.


When talking about immutability in cryptocurrency, we are referencing blockchain. To be immutable means no one is able to alter or change data after it is made. This makes blockchain unique in relation to standard records or data sets.

You can still carry out more research on the topic. It will enable you to get more knowledge and a better understanding.

What Are the benefits of Immutability?

The benefits of immutability are numerous. However, some benefits of immutability are high security, data integrity, easy auditing, and fraud prevention on blockchains. Some other benefits of immutability, are contained above.

Is Blockchain Immutable?

Many people always ask is blockchain immutable. As blockchain is immutable, doesn’t mean its data can’t be altered. So the answer to “is blockchain immutable?” is yes.
