### NIP Updates
- **01:01:34 NIP-34 (Git Stuff): Add nostr:// clone URLs (PR #2312) — Merged**
PR #2312 adds nostr:// clone URL patterns to NIP-34 for repository discovery and cloning via git-remote-nostr helpers. It defines direct, human-readable, and relay-hinted formats and tightens repository identifier handling.
- **01:03:43 NIP-63a: Minimal Payment Gateway Descriptor (PR #2315) — Open**
PR #2315 proposes kind 10164 replaceable events for describing creator payment gateways, pricing models, and subscription rules. The goal is client interoperability without provider-specific hardcoding.
- **01:05:30 NIP-XX: Relay Self-Declaration Manifest and Retention Horizon (PR #2314) — Open**
PR #2314 proposes kind 10100 relay manifests and a HORIZON message for explicit retention boundaries before EOSE. It aims to replace opaque empty responses with machine-readable retention limits.
- **01:08:11 NIP-TPLD: Transient Private Location Data (PR #2309) — Open**
PR #2309 introduces kind 20411 for encrypted per-recipient geolocation sharing using NIP-44 payloads, ttl hints, and ephemeral relay handling semantics.
- **01:09:37 NIP-5C (Scrolls): WASM programs update (PR #2281) — Open**
PR #2281 advances Scrolls conventions for publishing and discovering WebAssembly programs as Nostr events, with runtime interface refinements and browser demo alignment.
- **01:12:35 NIP-44 large payload support (PR #1907) — Open**
PR #1907 proposes backward-compatible support for payloads beyond the 65,535-byte limit, primarily to unblock large NIP-46 remote-signing responses such as large kind 3 lists.
- **01:16:59 NIP-C7: Restrict kind 9 to chat views (PR #2310) — Open**
PR #2310 requires clients rendering chat views to fetch only kind 9 messages, reducing context loss when mixed with kind 1 notes or kind 30023 articles.
### NIP Deep Dives
- **01:21:18 NIP Deep Dive: NIP-29 (Relay-based Groups)**
NIP-29 defines relay-managed groups where membership and moderation are enforced by the relay, using IDs in `'` format and `h` tags on group events. It introduces moderation and config kinds, including 9000-9022 for role and membership actions and 39000-39003 for group metadata and policy publication. The model prioritizes operational simplicity over confidentiality, because the relay can read content, so it targets public and semi-public communities rather than end-to-end private chat use cases.
- **01:36:22 NIP Deep Dive: NIP-90 (Data Vending Machines)**
NIP-90 standardizes request, result, and feedback flows for paid computation on Nostr across kind ranges 5000-5999, 6000-6999, and 7000. It defines structured job inputs, outputs, bids, parameters, payment-required statuses, and chaining semantics so multiple providers can fulfill pipeline steps. Current implementations and client support include growing DVM tooling and invoice rendering, with encrypted request options available when customers target a specific provider.
