DAG is a directed graph data structure that uses a topological ordering. The validation of a certain transaction is decided by the number of transactions behind it.
The rate of transactions coming back into the network is lower with more transactions behind it, which makes the transaction safer.
DAG is built with a blockless nature, the transactions run directly into the DAG networks. The whole process is much faster than those of blockchains based on PoW and PoS.

The project is simple to grasp. You can follow up with its development using the links i attached to the article. I will be making another post soon, stay tuned. :)
