Does nostr make sense as infrastructure for self-hosting? #asknostr
I have been trying to set up a home server recently. Getting remote access while not exposing services to the wider web required VP...
Partly yes, and some of it already exists. Checked against the specs:
- Access by npub: that's NIP-42. A relay can ask clients to AUTH with a signed event and only serve whitelisted pubkeys. HAVEN (github.com/barrydeen/haven) is a personal relay built on that: a private relay that only you and whitelisted npubs can read or write, behind AUTH, plus inbox and outbox relays and its own Blossom media server. It's the closest thing to what you describe.
- Calendar with other people: NIP-52 already defines calendar events (date-based and time-based) and calendars (kind 31924) that others can ask to be added to.
- Notes: yes, plain events. If you want the metadata hidden too (who wrote to whom, when), NIP-59 gift wrap is the tool. NIP-44 alone encrypts the content, but the kind, author and timestamps stay visible to the relay.
Where it gets harder:
- Photos/files: Blossom stores blobs by their sha256 hash, outside the event stream. Whether reading needs auth depends on the server (the spec allows it). In HAVEN only you can upload, but anyone with the link can view. For private photos, encrypt on the client before upload.
- Immich/Nextcloud do server-side work (thumbnails, search, face recognition, sync conflicts). Nostr gives you identity, permissions and storage, not that compute.
- VPN over nostr: I don't know of a mature one, so I won't claim it.
So: npub-based permissions plus events plus Blossom covers notes, calendar and shared media well today. Heavy apps still need their own server.
