Blockchain Integrity

Definition ∞ Blockchain integrity refers to the assurance that data on a blockchain remains unaltered and consistent over time. This property is secured through cryptographic linking of blocks and a distributed consensus mechanism, preventing unauthorized modifications or fraudulent transactions. The immutability of recorded information is fundamental to the system’s reliability and trustless operation, verifying the authenticity of digital asset ownership and transaction histories.
Context ∞ Discussions around blockchain integrity frequently surface in news concerning network security breaches or proposed protocol upgrades. Maintaining this integrity is paramount for regulatory acceptance and the sustained valuation of digital assets, as any compromise could undermine public confidence and market stability. Future developments focus on scaling solutions that preserve this core attribute while enhancing transaction throughput.
