This week the builders explore Bitchat's transition from C to Rust for memory safety, the emerging role of AI in reviving abandoned Nostr projects, and the ongoing debate around quantum-resistant cryptography. The panel dives deep into relay trust mechanisms, NIP standards, and the latest client releases.

### Infrastructure & Security

- **Bitchat Rust Migration** - The transition from C Tor to Rust Arti brings memory safety to secure messaging, with significant mobile stability improvements

- **Digital Kevlar** - Discussion of hardened communication layers and what memory-safe code means for financial applications handling Cashu ecash

### AI in Development

- **AI-Assisted Maintenance** - How AI tools are changing software maintenance and upgrades across the ecosystem

- **Reviving Abandoned Projects** - JeffG discusses using AI to resurrect Listr after over a year of dormancy, touching every file in the codebase

### Protocol Updates

- **NIP-29 Clarifications** - Important clarification that relay keys use WebSocket URLs, not pubkeys like other NIPs

- **Trusted Relay Assertions** - New draft NIP building on NIP-66 for standardized relay trust scoring (0-100 scale)

- **The Trust Problem** - Extended discussion on who watches the watchers and the economics of relay reputation

### Post-Quantum Cryptography

- **Quantum Resistance in Nostr** - Current proposals for ML-DSA-44 and Falcon-512 signatures

- **Timeline Reality Check** - Google Willow has 105 qubits; breaking current crypto needs roughly 1 million

- **Crypto Agility** - Why the narrative matters as much as the implementation

### NIP Deep Dives

- **NIP Standards and Relay Information** - How NIP-11 and NIP-66 work together for relay discovery

- **New Architecture Patterns** - Building applications on top of the evolving protocol stack

### Client Releases

- **Amber v4.1.0 Pre-release v3** - Android signer updates

- **Zeus Pull Requests** - 17 merged PRs focusing on NIP-47 and Cashu improvements

- **Primal Android** - Wallet backup flows and NIP-92 media dimension support

- **White Noise & Marmot** - Privacy-preserving push notification developments

### Code Changes

- **NIP-3 Rework** - OpenTimestamps attestation improvements

- **NostrDB Streaming Queries** - Zero-allocation fold queries for relay performance

- **Damus Open PRs** - Current development focus
