Pirl will run 3 separate Masternode types. Each of these serves a different purpose. Premium masternodes encompass the features of both of the other masternodes, while also supporting aspects of the Pirl Network such as peering, and consensus.
Content Masternodes provide publicly accessible file storage for the media needed for dApps and the marketplace to function.
Storage Masternodes provide digital downloads for the marketplace and can be used as a backup file server for individuals and organizations. The storage nodes are not released yet.
