Chain Integrity

Definition ∞ Chain integrity refers to the assurance that a blockchain’s historical record of transactions remains unaltered and consistent. This property is maintained through cryptographic linking of blocks and consensus mechanisms, making past data resistant to modification. It guarantees the immutability and reliability of the distributed ledger. Preserving chain integrity is paramount for the security and trustworthiness of any blockchain network.
Context ∞ News concerning chain integrity often reports on successful network upgrades, security audits, or, conversely, on potential vulnerabilities or attacks. The situation highlights the ongoing efforts by blockchain developers to strengthen network resilience against various threats. A critical future development involves advancements in cryptographic techniques and consensus algorithms that further reinforce the immutability and tamper-proof nature of distributed ledgers, ensuring data remains verifiable and trustworthy.
