This week we cover Bitchat's security audit by Cure53, which found 12+ security issues including uncleared Diffie-Hellman secrets and signature verification gaps. The team responded with 17+ pull requests fixing forward secrecy, thread safety, and memory exhaustion vulnerabilities. NIP-71 merges bringing addressable video events with update-in-place metadata. A post-quantum cryptography NIP proposes ML-DSA-44 and Falcon-512 signatures with ML-KEM key agreement to protect against future quantum attacks. We also discuss the BOLT12 offers debate and the Audio Track NIP for standardizing music and podcast events. Our NIP deep dive covers NIP-51 bookmark lists and NIP-65 relay metadata, explaining how both use replaceable events for organizing content and connections. Amethyst v1.05.0 ships bookmark support, voice notes, Web of Trust scores, Quartz database migration, and an early desktop release. Nostur v1.25.3 improves NIP-17 DMs with reactions, replies, and NIP-46 remote signer support.
