The main innovation behind IOTA is the Tangle. It’s a novel new distributed ledger architecture that is based on a DAG (Directed Acyclic Graph). IOTA was created is to enable and to be the backbone of the Machine Economy. We envision a future where Machines trade resources (computation, electricity, storage, bandwidth, data etc.) and services with each other without the involvement of any third party —purely Machine-to-Machine. As the Internet of Things starts unleashing itself, the need for “Smart Decentralization” is apparent.
