Certified DAG Structure

Definition ∞ A certified DAG structure refers to a Directed Acyclic Graph where the integrity and order of data elements are cryptographically verified. Each node or transaction within the DAG is confirmed as legitimate, preventing tampering or unauthorized alterations. This certification process ensures the reliability and immutability of the data structure.
Context ∞ In distributed ledger technologies that utilize DAGs instead of traditional blockchains, a certified DAG structure is paramount for establishing transaction finality and data consistency. News in this sector often discusses advancements in certification methods to enhance scalability and security without compromising decentralization. This structure is a key differentiator for certain next-generation digital asset platforms.
