My gripes so far (I haven't finished it yet) are that you used a picture of China when you explained a guy sending money to Thailand. It's not a big deal and the concept still works, but it's the kind of continuity detail that would bring your page up a level.
Also, you talked about Bitcoin and you said "pre-lightening", but it should be "pre-lightning".
"Lightening" with an "E" is to make something lighter in, like skin lightening cream that Michael Jackson used.
I see lot of answers indicating the meaning of DAG (Directed Acyclic Graph) but no answers on its applications. Here is a very simple one -
Pre-requisite graph - During an engineering course every student faces a task of choosing subjects that follows requirements such as pre-requisites. Now its clear that you cannot take a class on Artificial Intelligence[B] without a pre requisite course on Algorithms[A]. Hence B depends on A or in better terms A has an edge directed to B. So in order to reach Node B you have to visit Node A. It will soon be clear that after adding all the subjects with its pre-requisites into a graph, it will turn out to be a Directed Acyclic Graph.
