# Nostr Compass #6
Nostr infrastructure levels up this week. Bitchat migrates to Rust's Arti for memory-safe Tor, eliminating crashes and battery drain. nostrdb-rs adds streaming queries for zero-allocation database ops. Listr returns after a year dormant with NDK 3 beta and pagination. Zeus merges 17 NWC fixes while Primal Android ships wallet backups and NIP-92 media dimensions.
Draft NIP for Trusted Relay Assertions proposes scoring relays 0-100 across reliability, quality, and accessibility metrics. NIP-11 self-reported relay docs combine with NIP-66 independent monitoring (kind 30166 events) for informed relay selection beyond hardcoded defaults.
Open PRs signal major architectural shifts: Damus embeds Arti for native Tor, implements Negentropy for efficient sync (megabytes to kilobytes), and adds Low Data Mode. Marmot's MIP-03 solves distributed chat race conditions with deterministic commit ordering.
