Hello fellow steemians
I have been following the IOTA project since it got listed on Bitfinex .
I myself have had some uncertanties regarding the "Tangle", in comparison to the distributed ledger. However listening to this interview really gave some answers and i would recommend you check it out.
Enjoy.
