Immutability

Immutability in the blockchain context refers to the characteristic of data that cannot be altered or deleted once it has been recorded on the blockchain. This ensures that all transactions and data stored are permanent, transparent, and resistant to tampering. Immutability is one of the core features of blockchain technology, offering trust and security in decentralized networks. For instance, once a Bitcoin transaction is confirmed and added to the blockchain, it cannot be undone or modified. This makes blockchain an ideal solution for applications where the integrity of data is critical, such as in financial services, supply chain management, and digital identity systems.
