Still very much in development (and will be for a long time before I release anything publicly), but Arx is a Closed Community Network Building tool built on Nostr that integrates everything any community needs, and it does so within a secure framework:

- Forums for large-scale discussions

- Voting and decision-making systems

- Member-to-member payments within the CCN (via Cashu)

- Community pools (multisigs that CCN members can vote to spend from)

- Microblogging (kind 0: similar to current Nostr applications)

- An integrated, community-wide WoT + ELO-based reputation system

- File sharing and synchronization

- Real-time chat (akin to Keychat, Simplex, or Signal)

- Offline and local-first capabilities (allowing you to work offline with automatic synchronization once reconnected to the network)

- and obviously 100% e2e encryption
