SPK will use Hive to store CIDs in order for the PoA system to work. The token system will also be built on Hive. Account names, etc everything will be Hive based except the video and image storage. Basically, we will use Hive as our immutable ledger of truth as the skeleton that makes up the entire network. IPFS will be used for the storage of video/images/text. The unique thing about the SPK network is users can have permanent data and be able to delete that data from the network if they choose. In fact, they will be paid to delete older videos.
