Having observed Iota a bit and being a bit disappointed by Byteball, I must say that I haven't understood the exact advantages of a DAG with respect to a blockchain, at least of a DAG based on the "transactions as blocks" paradigm like Iota and Byteball (instead, a limited DAG-based approach like in Ethereum seems to have some advantages).
Iota cites scalability (mainly, as far as I understand it, because of fast transaction propagation/validation), but small-block blockchains should have the same advantages. Iota's zero-fee paradigm seems specific to its design and not to a DAG (Steem, for example, being blockchain based also has zero fees). And then there is the issue to get transactions confirmed that looks pretty difficult in Iota. In both Iota and Byteball, as far as I know, also still centralized servers work as the "clock" of the system.
So I would be really grateful if someone could explain the advantages of a DAGcoin and what is its real potential. (
This thread also was not helpful, but I have some hope that in this subforum there are more technically skilled people than in the altcoin forum.)
Also, I have heard also that research is going on to integrate the concept into Bitcoin in the far future. If someone knows more, I'd be grateful for links about that.
