In the context of blockchain, 'immutable' refers to the characteristic of data being unable to be changed or altered once it has been added to the blockchain. This means that once a transaction or record is added to a block and validated by the network, it becomes part of a permanent and unchangeable record that is stored across multiple nodes in the network. This feature ensures the integrity and security of the data on the blockchain, as any attempt to alter or tamper with the data would be immediately detected by the network.

Immutable in the context of blockchain refers to the characteristic of data stored on the blockchain being unchangeable and tamper-proof.
Once data is added to a blockchain, it becomes a permanent part of the record and cannot be altered or deleted. This is achieved through the following mechanisms:
- Consensus Mechanisms: Distributed consensus mechanisms, such as Proof-of-Work or Proof-of-Stake, ensure that all nodes in the network agree on the validity of transactions and data added to the blockchain.
- Cryptographic Hashing: Transactions and blocks are linked together through cryptographic hashes, creating a chain of data. If any data is altered, the hash will change, invalidating the block and any subsequent blocks built on top of it.
- Decentralization: The distributed nature of blockchain networks means that no single entity has control over the data stored on the blockchain. This makes it difficult for malicious actors to alter or delete data.
The immutability of blockchain provides several important benefits:
- Security: It ensures that data is protected from unauthorized modification, preventing fraud and data manipulation.
- Transparency: All data is publicly available and verifiable, providing a transparent record of transactions and events.
- Trust: Users can trust that the data on a blockchain is accurate and reliable, as it has been validated by the decentralized network.
Examples of immutable data stored on blockchains include transaction records, smart contract code, digital assets, and identity information.
