Microsoft and IOTA partner for crypto IOT

IOTA is an interesting take on distributed consensus. Instead of a blockchain architecture, IOTA uses a Directed Acyclic Graph ("DAG"), which they call the "Tangle". A unique property of this configuration is that the network scales linearly as the number of nodes increases - in other words, the more people use the network the faster it becomes. This would seem to be a great way to solve the scaling issue that has come to the forefront of blockchain engineering challenges, but questions remain around security and performance.
