What is Immutability?

Immutability is among blockchain’s key characteristics, meaning that data recorded on a blockchain network cannot be manipulated. The immutability offers a high level of security because the blockchain network is an immutable or unchangeable database. Due to their immutable nature, transactions registered on a blockchain cannot be altered, replaced, or falsified. Transactions on blockchains can be easily audited, which augments the trust in the particular network.

The immutability feature enables organizations and companies to increase their efficiency by allowing them to keep a historical record of their transactions, activities, and processes. In theory, immutability is vulnerable to the so-called 51% attack. However, executing this attack requires a lot of resources and would be very expensive. Nevertheless, networks with lower hash rates may be more vulnerable to the 51% attack because the required hashing rate can be obtained at a lower cost.
