TL;DR — This Week
- Nostr Web of Trust (WoT): New nostr-wot GitHub org and nostr-wot.com site launch open-source tools for trust graph computation, visualization, and social-distance spam filtering; integrates follow lists (NIP-02), mutes, reports for decentralized reputation.
- Group Messaging & Marmot/Concord: Marmot spec adopted with ongoing MDK/White Noise/Amethyst work; Vector shifts to Concord protocol; NIP-29 cluster clarifications for group relays; focus on larger groups, signing, interop.
- Mesh & Offline Identity: Bitchat 1.6+ adds NIP-13 PoW, opt-in gateways; Sonar spins off as cross-platform mesh client; real-world event use for permissionless BLE multi-hop pseudonymity.
- NIP Evolutions: NIP-29 refinements, NIP-46 timeout fixes, kind:10011 favorite follow sets merge; trusted relay assertions debated.
- Portable Keys & Clients: Zapstore 1.1.0 introduces portable encrypted device keys with Amber backup; Amber v6.3.0 groups bunker approvals; Iris nostr-social-graph 2.0; NostrKey and remote signers mature.
- Deployments & Ecosystem: Satlantis/BTCHEL Nostr npub check-ins; P2P marketplaces (Mostro) default to seed-derived identities; grants and client updates emphasize AI/agent identity and discovery.
Freedom-tech takeaway: Nostr's key-based pseudonyms (npub/nsec or NIP-06 seeds) are gaining sophisticated WoT reputation systems for organic spam/Sybil resistance, portable hardware/remote signing, and mesh bridges—enabling identities that persist across failures, platforms, and attacks. Momentum in trust graphs and group primitives points to production-grade sovereign social/payment/mesh infrastructure.
The Week in Detail
Nostr Web of Trust & Reputation Systems
Nostr WoT infrastructure advances with dedicated tooling for decentralized trust and filtering: - nostr-wot GitHub organization and nostr-wot.com site provide open-source tools for building, querying, and visualizing trust networks based on social graphs. - Core mechanism: Social distance from trusted seed pubkeys via follow graphs (NIP-02), augmented by mutes/reports; enables client-side spam filtering and reputation scoring without central servers. - Use cases: Marketplace reviews, content recommendation, Sybil resistance in governance/airdrop contexts; extends classical PGP WoT concepts to Nostr's broadcast model. - Related: Discussions on extending WoT for AI agent verification and trusted assertions.

Marmot Protocol, Concord & Encrypted Groups
Group pseudonymity via MLS-over-Nostr continues evolving: - Marmot spec formally adopted; MIPs and MDK library receive updates for signing proofs, capabilities negotiation, state convergence. - Client shifts: Vector moves group chats to Concord (community protocol); Amethyst implements clean-room Concord support alongside Marmot interop. - NIP-29 updates clarify group relay migration, forks, and cluster behaviors for better scalability. - White Noise and Amethyst integrations emphasize iOS/Android bindings, external signers, and larger-group optimizations. - Ties into Nostr and remote signing for compartmentalized group identities.
Bitchat, Sonar & Mesh Pseudonymity
Offline-first identity layers advance: - Bitchat enhancements (NIP-13 PoW for channels, prekey bundles, transitive verification, mesh-to-Nostr opt-in gateways) enable robust event coordination and geohash presence without accounts. - Sonar emerges as cross-platform spin-off from Bitchat, focusing on BLE multi-hop store-and-forward with Nostr fallback. - Real deployments: Hybrid online/offline at Bitcoin events, journalist tools stacking with Tor/Nostr for surveillance resistance. - Complements 08-Mix-Networks and off-grid sections.
NIP Proposals, Portable Identity & Signers
- NIP-46 remote signing fixes (timeout handling); NIP-55 bunker support in Amber.
- New: kind:10011 favorite follow sets for curated trust lists; debates on NIP-47 wallet simplifications and trusted relay assertions.
- Portable keys: Zapstore adds encrypted device key portability with Amber backups and auto-updates; emphasis on "your keys, your identity" across devices/apps.
- Broader: NostrKey extensions, biometric/hardware signers; early post-quantum explorations alongside secp256k1.
