Hashgraph thousand times faster then blockchain, limited only by bandwidth and much more secure.
they claim that ´In hashgraph, every container is used, and none are discarded. So all the branches continue to exist forever, and eventually grow back together into a single whole. This is more efficient. Furthermore, blockchain fails if the new containers arrive too quickly, because new branches are sprouting faster than they can be pruned. That is why blockchain needs proof-of-work or some other mechanism to artificially slow down the growth. But in hashgraph, nothing is thrown away. So there is no harm in the structure growing quickly. Every member can create transactions and containers whenever they want. So it is very simple, and tends to be very fast.
Really interesting development thanks to the massive dedication of more and more individuals to regain bits of freedom
