In computing and graph theory, a Directed Acyclic Graph (DAG) is a finite directed graph with no directed cycles. This implies that there is no way to start at some node and follow a consistently-directed path that eventually loops back to that node. In the context of blockchain technology, DAGs are employed to enable faster transactions and higher throughput by allowing multiple branches of transactions to be recorded simultaneously without the restriction of a linear transaction chain, as seen in traditional blockchains. This structure can theoretically accommodate a vastly scalable number of transactions, making it a compelling alternative for decentralized systems.
