The Directed Acyclic Graph is a synonym for Distributed Ledger Technology (DLT). The data structure of DAG is different which connects different pieces of information together. DAG helps solve various problems such as data processing, finding the best route for navigation, scheduling, and data compression. 

The Directed Acyclic Graph looks similar to the image. The DAGs are made up of vertices and edges. The direction of the lines heads in one direction as shown in the image. They are acyclic, which means that the vertices don’t loop back on themselves. It means that if you start at one point in the graph, you cannot return to the same point. Such data structures are used in the scientific or medical field to analyze the connection between variables and determine their impact on each other.
