Hi HN!

Nostr-CRDT is an experimental project that connects Yjs [1] (a proven, high performance CRDT) with Nostr [2].

I wanted to learn about the Nostr protocol and see if it'd be possible to send updates to state (e.g.: edits of a rich text document, updates to a todo list) over Nostr.

Nostr describes itself as "The simplest open protocol that is able to create a censorship-resistant global "social" network once and for all.".

I like the idea of a decentralized social network, but what if we can decentralize more kinds of apps and create decentralized, local-first collaborative applications? I've been exploring this area for a while and earlier shared a Show HN post that does this over Matrix [3].

There's still lots to figure out, but imo it's a very exciting and rapidly developing space - looking fwd to your thoughts already!
