IS BLOCKCHAIN (BY DEFAULT BITCOIN) THE FUTURE OF EVERYTHING?

[Ethan Manson]

What is the overall scope of change you expect blockchain to have on the world. Or any other distributed immutable open system. Hashgraph for instance?

[rgsnedds]

Isn't hashgraph completely closed-source?

For that reason, it'll go nowhere until it's an open source code.
DAG is the future, although blockchain databases will continue, as a cheaper option for companies who who cannot afford to invest in DAG protocols.
