Published new Nostr Community Convention: ncc-05 - Identity-Bound Service Locator Resolution
NCC-05 update published
NCC-05 now clearly defines identity-bound, encrypted service locator resolution for dynamic ip:port endpoints, without DNS or public infrastructure.
What’s new and clarified:
Explicit anchored vs unanchored operating modes
Anchored mode (recommended): NCC-02 provides identity and trust, NCC-05 provides private reachability
Unanchored mode (permitted): supports ephemeral, P2P, and bootstrap use cases
Formalised endpoint object format with deterministic selection
Stronger guidance on TLS key binding (k) to prevent endpoint substitution
Clear TTL, expiration, caching, and refresh semantics
Deterministic record and endpoint selection to improve interoperability
Explicit support for private and invite-only services
NCC-05 remains client-agnostic, relay-agnostic, and fully compatible with existing Nostr primitives, while enabling private, low-cost alternatives to Dynamic DNS.

NCC Sidecar v1.2.2 is live
This release focuses on backup integrity, recovery, and more reliable discovery for self-hosted services.
Encrypted backups by default
Node backups (Kind 30001) now use NIP-44 encryption. Managed service lists and configuration data are no longer published in plain text to relays.
Improved admin recovery
A new two-stage bootstrap flow allows full recovery after reinstall. Logging in is enough. Sidecar locates your encrypted bootstrap keys linked to your identity and restores state automatically.
Updated resolution engine
Now running ncc-06-js v0.6.0, improving discovery resolution, protocol filtering, and overall reliability.
UI refinements
Standardised theming for cleaner dark mode transitions, relay management restored, and a new “Copy NPUB” shortcut added to the dashboard.
The goal remains simple: make Nostr services easier to discover without compromising privacy.
