Verifiability

Definition ∞ Verifiability pertains to the ability to ascertain the truth or correctness of a statement or claim. In blockchain, this often relates to the transparency and immutability of transaction records, allowing any participant to independently audit and confirm data integrity. It is a foundational principle for trust in decentralized systems.
Context ∞ Verifiability is a constant point of discussion regarding blockchain security, smart contract audits, and the accuracy of on-chain data. News often highlights instances where verifiability is compromised or enhanced, influencing trust in specific protocols or applications. Developments in zero-knowledge proofs and formal verification methods are key topics that directly impact this attribute.
