Data Immutability

Definition ∞ Data Immutability signifies that once data is recorded or written to a system, it cannot be altered or deleted. This property ensures the integrity and permanence of information, making it resistant to tampering or unauthorized modification. In the context of blockchain technology, immutability is a foundational characteristic that underpins the trustworthiness and security of distributed ledgers. Transactions, once confirmed, are permanently etched into the chain’s history.
Context ∞ Data Immutability is a core principle discussed when evaluating the security and reliability of blockchain protocols and decentralized applications. News reports often emphasize this attribute as a key differentiator from traditional databases, highlighting its role in preventing fraud and ensuring data provenance. Debates may arise concerning the practical implications of immutability, particularly in scenarios requiring data correction or privacy controls, leading to discussions about potential solutions like zero-knowledge proofs or selective data obfuscation. The absolute permanence of recorded data is a significant factor in building trust within decentralized systems.
