According to Popov, the IOTA DAG through GHOST protocol has made the Blockchain data structure from a chain to a tree structure which improving the confirmation times and overall security of the network (2018). Popov argument is merely improving from the Bitcoins Blockchain consensus and creation weakness and its data structure. As such, improvement the employment of DAG shall provide significant speed for the DLT protocol. 

On the other hand, it is not certain at this point, how IOTA DAG is able to improve the performance and moreover, the ioT devices are predominantly relatively smaller scale chip which could not support heavy hashing algorithm such as SHA256 with a Proof-of-work algorithm in solving the nonce.
