Home » Glossary » Immutability



The term immutability means unchangeability and is one of the key features of Bitcoin and blockchain technology in general. It refers to a blockchain network’s ability to remain an unalterable, indelible, and permanent history of transactions. 

Understanding the term

Immutability makes blockchain networks resistant to any efforts to manipulate, replace, or falsify data by a third party. Immutability enables a high degree of data integrity as all historical transactions can be audited at any point. The immutable properties of public blockchain networks can enhance their trust and audit system.

Blockchain is an immutable database as its data cannot be manipulated. This is possible due to hash values being unique which depend on the block’s content. It makes verifying information much simpler as the time and cost of audits are reduced.

While immutability is one of the core advantages of cryptocurrencies and blockchain technology, the data stored on blockchains aren’t fully resilient to vulnerabilities. Immutability can potentially transform the existing auditing process into a quick, efficient, and cost-effective procedure. This will bring more trust and add integrity to data-driven businesses.


Immutability is described as one of the core benefits that cryptocurrencies and blockchain technology in general offer. Because of this, public blockchains can enhance the current auditing system and reduce the time and costs of audits. A high degree of data integrity is thus achieved since it allows all historical transactions to be audited at any point in time.
