Even if you don't use Nostr as a microblogging social network, it can provide a useful layer. For example Trystero https://oxism.com/trystero (MIT licensed) can use it to establish P2P WebRTC connections without requiring a central server.

Thats cool I have been thinking of using nostr , Bittorrent DHT and Mastadon as a cencership resistant multi channel redundant broadcast beakon. All methods must go down before your nodes can't find each other anymore.

This is very interesting. In a similar vein, I was wondering a while ago if either Nostr or ATProto could potentially work as part of a peer-to-peer instant messaging system, specifically as a way to have persistent storage and offline messaging. (But using it to establish connections is pretty clever, too.)

wow this is amazing. was thinking about whipping something similar for my own project but glad that someone had same problem before. saved me some time.
