- **01:52:28 Small new surfaces: relayk.it and Brainstorm Search**
relayk.it is a browser relay discovery client built with Shakespeare, and Brainstorm Search ships as a single-page Nostr search UI.
### NIP Updates
- **01:53:26 NIP-67: EOSE Completeness Hint (PR #2317) — Open**
NIP-67 PR #2317 proposes an optional third EOSE element to signal whether a relay returned all matching stored events. The extension is backward compatible and helps clients stop pagination when completeness is explicit.
- **01:55:01 NIP-5D: Nostr Applets (PR #2303) — Open**
PR #2303 proposes NIP-5D applets as sandboxed interactive front-end payloads, positioned between static NIP-5A sites and executable NIP-5C scrolls.
- **01:56:05 NIP-29: Subgroups spec (PR #2319) — Open**
PR #2319 extends NIP-29 with subgroup hierarchy and moderation scoping while keeping compatibility for plain single-h tag messages.
- **01:57:05 NIP-29: Explicit role permissions on kind 39003 (PR #2316) — Open**
PR #2316 defines explicit operation grants and optional expiries on kind 39003 role events so relay and client permission semantics are machine-readable and consistent.
- **01:57:56 NIP-11: access_control field for gated-relay discovery (PR #2318) — Open**
PR #2318 adds optional access_control metadata to NIP-11 relay documents so clients can surface gating mode and access request endpoints.
- **01:58:35 NIP-63a: Minimal Payment Gateway Descriptor (PR #2315) — Open**
PR #2315, previously covered in Newsletter #18, continues iterating on kind 10164 descriptor structure and subscription-tier field layout.
- **01:59:09 NIP-XX: Agent Reputation Attestations (Kind 30085) (PR #2320) — Open**
PR #2320 proposes kind 30085 attestations for service and agent reputation, including bounded scores, evidence references, and signed target attribution for market filtering.
- **01:59:58 NIP-TPLD: Transient Private Location Data (PR #2309) — Open**
PR #2309 continues work on kind 20411 transient location data, with ongoing tuning around NIP-44 per-recipient encryption and ttl retention semantics.
- **02:00:43 marmot-ts 0.5.0 release PR (PR #70) — Open**
PR #70 prepares @internet-privacy/[email protected] with breaking API and storage changes, including dual key package event support and invite/group management moved onto MarmotClient.
### NIP Deep Dives
- **02:01:10 NIP Deep Dive: NIP-72 (Moderated Communities)**
NIP-72 defines communities as kind 34550 addressable events with metadata and moderator sets, where submissions carry community `a` tags and moderator approvals are published as kind 4550 events. The design keeps moderation transparent and portable across relays because approvals are signed, auditable Nostr events and community identity is replaceable but stable via `d` tag coordinates. It trades strict gatekeeping for broad compatibility: submissions are publicly writable, while curation happens at the client read layer through approved views.
- **02:07:06 NIP Deep Dive: NIP-57 (Zaps)**
NIP-57 standardizes Lightning-linked zap requests (kind 9734) and receipts (kind 9735) with verifiable linkage between request intent, invoice amount, and settlement preimage. It relies on LNURL callback coordination and requires clients to validate wallet-server signatures, invoice description hash commitments, and payment proof before counting receipts as real zaps. The model also supports private and anonymous zap variants, split payouts, and higher-level goal tracking as used by NIP-75 and Amethyst’s PR #2469.
