Hi,

thank you for the response, here are my impressions on the youtube link:

~3:30 — No, DAG and blockchain do not differ in that point. For a DAG and for a blockchain the consensus algorithm can be exchanged. It is claimed here that blockchain is interwoven with the consensus algorithm but in fact, Nakamoto consensus can be exchanged for byzantine fault tolerant consensus or something else. The fundamental difference is the synchronization. Blockchains synchronize by agreeing on a set of transactions in one block, for IOTA, the consensus is asynchronous (without coordinator) and even heterogenous in space, so a transaction might be part of consensus in one part of the network, but is not yet part of the consensus in another part. In Bitcoin this cannot happen, because only the transactions within one block are asynchronously ordered, the blocks to each other are synchron.

~30:30 — Here is a very typical argument of IOTA enthusiasts. But why is it that more users equal more transactions and faster processing? The only thing I see is less statistical variance until your tx gets picked up by another tx, but for global consensus, I think this point is just wrong.
