I found this https://github.com/Marie673/Torrent_Proxy

Its in chinese so idk if its whats needed but if each instance also acted as a torrent proxy then thats decentralised domain agnostic file hosting that doesnt break frontends but also allows clients to update to do resource resolution themselves while helping to serve the fediverses files as a whole.

am I the only one who would advocate for text only storage: no. This comment also gets my point? There should be text only lemmy instances which only save text and do not allow any kind of image posting or storage.

• text is less offensive to consume and moderate than evil images or video
• text is way more information dense and can be even compressed more! Truly the green biosphere friendly data format. I would be willing to save text only data of strangers on my hard-drive, but not images or video. Could even be valuable llm analysis training data.

Yes people could post base64 encoded images, but that is a larger technical barrier and can be detected. If image storage is really need, images should be heavily compressed (webp 90% quality loss), provided as links to external sites, and whenever possible svg / vector graphics should be preferred.
