We have considered three scenarios:

The first scenario is hosting images and videos used in chat rooms. These need to be end-to-end encrypted and stored for about one or two weeks. Users typically access them only once within the chat room. No separate interface is needed—configuration can be done in the chat settings.

The second scenario is hosting images and videos for microblog posts. Since they are meant to be viewed by followers, encryption is not necessary, and the files should be stored for a long time. No separate interface is needed—configuration can be done in the microblog client, similar to setting a relay.

The third scenario is backing up important files. These must be end-to-end encrypted, stored for a long time, and require a dedicated interface to display all saved files.

For the third scenarios where files need to be end-to-end encrypted, our idea is to perform the encryption on the client side before uploading. We hope to see a Mini App like this, where users can log in using their own key pair and optionally pay with their wallet.
