Immutable Record Keeping

Principle

Immutable record keeping refers to the practice of storing data in a manner that prevents any alteration or deletion once it has been recorded. In the context of blockchain, this is achieved through cryptographic hashing and distributed ledger technology, where each new block contains a hash of the previous one. This creates an unchangeable chain of data, ensuring the integrity and permanence of information. It is a core feature of decentralized systems.
