Blockchain achieves immutability through cryptographic hashing and consensus mechanisms: Every block contains a hash of the previous block — altering any data changes the hash, breaking the chain. Consensus protocols (like PoW or PoS) ensure all participants agree on the same valid chain. This makes tampering virtually impossible without controlling a majority of the network (e.g., 51% attack). |

Key point: Immutability arises from cryptographic linkage + decentralized consensus.
