A Super Node is where the Nostr idea becomes physical. It can help a venue act as a local relay, local service point, payment context and hospitality node rather than a disconnected offline place.
Why local infrastructure matters
If Nostr stays only as a social feed, it cannot do the full Crays job. Venues need local presence, access, orders, payments, booking context, member status and reliable service workflows.
Super Node functions
A Crays Super Node can support local relay functions, mesh networking, venue-specific services, POS/PMS integration, Lightning payment flows, guest context, staff context and local community discovery.
- Relay. Local social and service context.
- Mesh. Venue-local peer and service connectivity.
- Payments. Lightning-native flows where appropriate.
- Hospitality. Bookings, orders, access, concierge and member state.
Relationship to NIPs
NIP-65 relay lists, NIP-42 auth, NIP-98 HTTP auth, NIP-57 zaps and NIP-47 wallet connect are especially relevant. The exact implementation should be product-led, not spec-led.
Business meaning
The Super Node lets Crays turn digital demand into venue operations. That is the bridge from social graph to real-world revenue.
