What is a DAG?

I noticed that Byteball and IOTA both use it and I was wondering how that differentiates the two from say BTC or ETH

Directed means A->B instead of A<->B, one-way. Acyclic means no loops, no path back to A from B. A graph is a bunch of nodes and edges, A and B are the nodes and the arrows are edges.

asynchronous transactions so much faster in the long run with more nodes. Does two previous transactions so weighted and more trusted nodes are less likely to accept shitty (doublespend) transactions. better tech, timestamps and contracts coming for iota

DAG looks like pic related. Most blockchains use a nondirected graph, in which all nodes are verifying each other, instead of this one-way graph. Both methods prevent a central authority.

Thanks guys, this was probably one of the more informative threads I've seen in a while

ETH uses DAG.
