Hey Nostr! I've been building Obelisk for nostr:nprofile1qywhwumn8ghj7mn0wd68ytnzd96xxmmfdejhytnnda3kjctv9uq3qamnwvaz7tmwdaehgu3wd4hk6tcpz4mhxue69uhhyetvv9ujuerpd46hxtnfduhsqgqlyngdnf7mkgsmqgr2sejssd60gjcq6uz2xn5trvlun29uzspcqckcm47g 's IDENTITY Hackathon and the public server is finally live. It's a Discord-style group chat (servers, channels, categories, roles, voice), but identity is 100% Nostr.

WoT-gated registration. Spam resistance comes from your follow graph, not captchas. If the server's reference Nostr account follows you, you're in.

  • Zaps in every message via Nostr Wallet Connect (NIP-47).

  • Archon, a resident bot + admin CLI that any AI coding agent (Claude Code, Codex, Cursor) can drive to run the community.

  • Games built in. Play Chain Reaction, Chess, or Tic-Tac-Toe against other members right inside the server.

  • Kind-0 profiles. Your Nostr identity just shows up correctly.

  • Real-time messaging over Socket.io, voice channels over a WebSocket audio relay, self-hostable via Docker.

Next on the roadmap is Nostr relay-based groups, so the whole thing becomes interoperable with the wider Nostr ecosystem instead of a walled garden.

It's fully open and the public showcase server is open to anyone with a Nostr key. Come log in and break things:
