Immutable Records

Definition ∞ Immutable Records are data entries that cannot be altered or deleted once they have been added to a system. This characteristic is a core feature of blockchain technology, ensuring the integrity and permanency of recorded information. Once a transaction or piece of data is committed to an immutable record, it is permanently preserved and auditable. This property is fundamental for establishing trust and accountability in decentralized systems.
Context ∞ The concept of Immutable Records is central to the value proposition of blockchain technology, underpinning its use in applications requiring high levels of data integrity. Discussions often center on the technical mechanisms that ensure immutability, such as cryptographic hashing and distributed consensus. Current debates also address the implications of immutability for data privacy and the right to be forgotten in certain regulatory contexts.
