## Show Notes
### Introduction
Episode 3 of the Nostr Compass Podcast celebrates five years of Nostr development with a comprehensive retrospective of December milestones from 2020 through 2025.
### Featured Topics
#### HODL Invoice Escrows in Shopstr
Shopstr's new trust-minimized payment system for physical goods using HODL invoices. The architecture locks buyer funds in their own wallet using Alby's `makeHoldInvoice`, with settlement triggered only after merchant inventory verification. The handshake flows through NIP-17 encrypted DMs with multi-merchant cart support.
#### Five Years of Nostr Decembers
**December 2020: Genesis**
- fiatjaf releases Branle, the protocol's first client
- One or two experimental relays serve early adopters
- The Telegram group @nostr_protocol launches
- Core architecture established: secp256k1 public keys, signed posts, dumb relay storage
**December 2021: Early Development**
- Nostr hits the Hacker News front page (110 points, 138 comments)
- Network runs on approximately seven relays with fewer than 1,000 users
- Branle receives private key import and multi-relay support
- Command-line client noscl provides terminal-based interaction
**December 2022: The Tipping Point**
- Jack Dorsey donates 14.17171699 BTC (~$245,000-$250,000)
- Twitter suspends journalists, announces bans on Nostr/Mastodon promotion
- NIP-19 merged, introducing bech32-encoded identifiers (npub, nsec, note)
- Client proliferation: Damus, Astral, Snort, Amethyst development begins
- 36+ commits to NIPs repository
**December 2023: Ecosystem Maturation**
- NIP-44 revision 3 merged after Cure53 security audit (10 issues found)
- ChaCha20 and HMAC-SHA256 replace flawed NIP-04 encryption
- OpenSats fourth wave of grants funds Lume, noStrudel, ZapThreads
- Nostr Wallet Connect v0.4.1 extends NIP-47 methods
- jb55 posts that 2024 may be "the last year of Damus"

- NDK achieves 162x faster cache queries
### Current Developments
#### Amethyst Desktop Module
PR #1625 creates a full `:desktopApp` module using Compose Multiplatform, with login and global feed screens functional. The architecture converts `:commons` to Kotlin Multiplatform, enabling shared UI between Android and desktop while laying foundation for iOS.

PR #1622 adds dedicated voice reply screens with waveform visualization, re-record support, media server selection, and upload progress indicators.
#### Direct Messaging and New App Features
Notedeck gains messaging in PR #1223, expanding beyond timeline browsing into direct communication.
#### Local Relays and Offline Functionality
Citrine can now host web applications, turning phones into local-first Nostr web servers. Automatic reconnection and event broadcasting when network connectivity returns.
#### Data Resilience and Synchronization
Discussion of patterns for maintaining data integrity across distributed relay networks.
#### Nostr as an Address Space
Exploration of Nostr's identity and addressing model beyond social applications.
#### Developer Tools and Ecosystem Growth
The Nostrability Developer Toolkit Registry maintains a curated list of SDKs and libraries across TypeScript, Rust, Python, Go, Dart, Swift, and more.
### NIP Updates
- **NIP-54** - Critical internationalization fix for wiki d-tag normalization, preserving UTF-8 letters for Japanese, Chinese, Arabic, Cyrillic, and other scripts
- **NIP-54 Djot migration** - Proposal to switch wiki content format from Asciidoc to Djot
- **NIP-XX Quorum** - Threshold multi-signature governance using FROST signatures
### Releases and Tools
#### ZapStore 1.0-rc1
Complete UI refresh, rewritten package manager, App Stacks for curated discovery, background update checking, infinite scrolling.
#### Messaging Innovations
KeyChat v1.38.1 adds UnifiedPush support for Android and Linux push notifications, plus biometric authentication.
#### Infrastructure Projects
- nak v0.17.4 - CLI tool update with Blossom mirror functionality
- Mostro v0.15.6 - Dev fee audit events through kind 8383 Nostr events
### Security Audits and Best Practices
Discussion of security patterns across the ecosystem: Marmot audit findings, Applesauce signature verification by default, proper key handling.
