EMPT is consented and mined from a mobile device. And the block chain data is stored on the mobile device. It's a project that started with the goal of a mobile-based network. Systematical cluster of devices enable to minimize resource use and it is possible to secure a lot of nodes by the widely distributed mobile devices. The network of EMPT is a very large network vertically with high availability, high data reliability. Also continuous scale-up is possible.
