The Directed Acyclic Graph (DAG) is a new structure of Distributed Ledger Technology (DLT) which has been marketed recently as Blockchain 3.0. It holds immense possibility for the future of DLT, solving many key issues associated with Blockchain and providing the platform for speedy transactions that could challenge the likes of Visa.

DAG technology is comprised of two fundamental concepts – its “directed” nature which means that the graph has direction, so that moving from node 1 to node 2 is not the same as moving from node 2 to node 1, and its “acyclic” nature making it impossible, starting from a particular node, to find a path back to that same node while following the direction of the system. This structure allows us to create a system that can run several transaction…
