A protocol and cryptocurrency using directed acyclic graph (DAG) architecture rather than blocks to confirm transactions. It is designed primarily for machine-to-machine (M2M) communication within the Internet of Things (IoT). It uses a proof-of-work (PoW) algorithm wherein each transaction must confirm two transactions preceding it to maximize efficiency and ward off spam.
