Hedera comparison to Aleph Zero
I randomly stumbled on this project when researching Hedera's TPS for a FUD conversation I was trying to shut down.
Very interesting project. They specifically call out Hedera on their FAQ page:
How Aleph Zero is different from Hedera Hashgraph?
A subtle but crucial structural difference is that in Hashgraph, each communication between two nodes creates an ‘event,’ which is a container for potential queued transactions. In Aleph, we decoupled communication between nodes (i.e., gossiping) and the creation of units (how we call our ‘containers’) since we believe that the 1:1 ratio between these actions is suboptimal by far. Besides that, Aleph provides a constant bound on the average number of rounds necessary to validate each transaction and put it into total ordering even during times of total asynchrony of the network. In Hashgraph’s white paper, the average number of rounds is not bounded and their liveness proof is based on a coin round, which provides for a probability of achieving liveness as less than one in a billion for validating a transaction during each round in an asynchronous scenario (assuming a committee size of 39).
There are also differences in the governance model. Aleph is fully permissionless, whereas in Hedera Hashgraph part of the committee (39 members) is chosen by the Hedera Hashgraph team. In Aleph, it is the coin holders who elect all of the validators of the network. Also, the Aleph algorithm is not patented. Most importantly, Aleph does not require license fees for users to build an application on the platform.
What are the "license fees" they mention here?

They are erroneously talking about the fact that swirlds is able to license the tech out for private implementations.
Hedera will never charge fees (other than the transactional ones) for anyone to build on the only public implementation of Hashgraph that will ever be authorized by swirlds.
Also, by their own admission, whoever controls the bulk of the Aleph tokens will control the voting rights for who is elected as a validator. This poses several problems of which who's to say an elected validator will even want to be one and if they are you won't know if there's been some form of collusion among Aleph whales to put a given validator in place.
The council Hedera is putting together is meant to balance Democratic process with speed of development and iteration. Aleph tries to paint the council as a weakness where in actuality it is a MASSIVE strength of which literally no one else in the entire space has.
This is why you see so many projects attack it.
