In a blockchain context, immutability refers to something that cannot be changed. This characteristic allows data to be irreversibly codified into the shared ledger of a blockchain network after transaction execution. Most non-blockchain computer networks are mutable, meaning that the information inside them can be modified, censored, or changed. Immutability allows a blockchain network user to send and receive crypto transactions that can't be reversed. It also can ensure the integrity of data for a decentralized application (dApp), blockchain cloud storage platform, and various other blockchain network applications.
