Peergos is an open alternative to Proton Drive offering end to end encrypted filesystem where the server is entirely a dumb host/storage. Put so far it relied on a centralised identity layer similar to Bluesky.

Mlkut.org is my personal effort to port that e2ee filesystem to Rust, simplify it, and replace the centralised identity with Pkarr.

As for why is that helpful, it is because Pkarr tells every client exactly who hosts your data at any moment in time giving you unbroken URLs and strong consistency, while the rest of Mlkut gives you full control over who can read and/or write to any folder or file in your filesystem.

That allows you to use wide variety of open source apps to author and share and publish, but it also allows for collaboration and you can compose these folders to build an emergent community, like forums or groups with moderation etc... there are things that you can't do with only these primitives, but for small world usecases, you can go so far with only this.

Let me put it this way; if you can imagine building it with Proton Drive / Google Drive, you should be able to build it with Mlkut, but also no vendor lock.
