Eric Wall has run through some of the marketing smoke from the Hashgraph team and laid out a pretty thorough trouncing of the protocol. Its a good fun read if you like that kind of thing:
Has anyone here the knowledge (and inclination) to lay out the differences parsec has from Hedera’s data structures and consensus scheme? Also perhaps more interestingly the reasons for similarities and deviations from the design. I’m afraid I’ve never got my head around it.
With Hashgraph about to launch a ‘public’ network it may be about to receive a lot more scrutiny.
