Sure! We are using Blockstack for authentication; it is a platform to have your identity safe with the help of blockchain. Scalable? It is easier as all the works are done in the client-side, so no server pressure there, and your data will be stored on the storage provider of choice although we have a default one with 10GB free storage for all the news users. (Always encrypted!) In the future, we will provide extended options like self hosting for enterprises.
