Directed Acyclic Graph (DAG)

CoinGecko | 更新日: Mar 03, 2020
Directed acyclic graphs refers to a data structure that is built in one single direction, yet branches out and never repeats. Directed = Connections between two points (nodes) have directions such that A -> B is not the same as B -> A. Acyclic = Opposite of cyclic where you’ll end up where you started from after some time. In an acyclic system, you’ll never encounter the same point (node) twice. Graphs = A structure consisting of points (nodes) that are connected. Compared to a regular blockchain data structure which operates in one straight chain, DAG based systems have more breadth as the network is similar to a expanding tree rather than a straight chain.
