Very good video @heiditravels!
We need to explore more of similar technologies. All of them(Blockchain, DAG, Hashgraph and many more that are going to be discovered in the future) are implementations of a higher abstraction known as DLT(Distributed Ledger Technology). We still need to figure out if Hashgraph is either a sister or a child of DAG technology though.
Keep up the good work!
Thank you for the key word - Distributed Ledger Technology (DLT). I didn't realize how many new discoveries where happening!
