Question: Hashgraph

[cptElijah]

Tested hashgraph for 4 users. 40 transactions per second, given that they are empty. Pretty bad result. Until more like mysticism... imho

How exactly did you test it?
IIRC it's closed source and you need a licence from Swirlds to run it.

SDK is on the website hashgraph.

They are totally different, are not they? Blckchain vs hashgraph. They are both a means for distributed ledger, but technically are different. Besides them, there is also a structure, naming DAG. Both DAG and hashgraph are blockless technology.

It is important that this distributed ledger. The idea is to eliminate the middlemen and to exclude the governing body.

Does anyone have a good understanding of the benefits / drawbacks of DAG based systems v all the hype going on around HashGraph? For example, Nano (formerly RaiBlocks) is DAG and says its infinitely scaleable. Other than the fact that the hashgraph is controlled by an private entity (which in itself makes it a non starter for me). Specifically from a scaleability, speed, or security, and privacy perspective.

This is a good article on the matter comparing scaling Blockchains and scaling DAGs.

DAGs have their own drawbacks with respect to DDOS and transaction propagation latency during high load periods.

Thanks. That was a very good article. However, I am not deeply skilled at the level of math or programming needed to know if there are differences between different DAG models (i.e. is there a difference and the same limitations between IOTA, Byteball, or Nano, for example). Any thoughts?

There are differences in the implementations.
This article compares IOTA and Raiblocks (now Nano)

Although they're all DAGs their consensus algorithms are different: Byteball is a "main chain" DAG, IOTA works with POW, and Raiblocks/Nano is a modified version of dPoS.
