VERDICT: A Cryptographically Verifiable Framework for Secure Data Lineage in Decentralized DAGs (opens in new tab)

Ensuring the integrity and traceability of data transformations in distributed systems presents significant challenges, particularly in environments where data privacy and decentralization are paramount\. This paper introduces a novel secure lineage verification system based on Directed Acyclic Graphs \(DAGs\) and homomorphic hash functions, VERDICT\. Our approach represents data artifacts and their transformations as two interconnected DAGs: a Data DAG tracking data dependencies and an Event...
