There are some other small demo projects, but pubky.app and Pubky Ring are the first major apps for the system.
Anyone can make any aspect of it they want. It's all open source and public data.
Discussion
Thanks, I take back my comment. I wasn't aware that the protocol was open sourced.
The main thing holding me back is the community and network that I have built on nostr.
Pubkey seems like an upgrade to nostr, why build it as an incompatible network instead of a few NIPs?
Sure, the main challenge with social graphs is their lack of portability. People call this "network effect" and believe it means that new networks cannot replace large networks...yet over time, they always do seem to get replaced ;)
