Could you build this?
Partial Building a cross-platform chat UI with Nostr protocol integration (NIP-44, NIP-4E) is achievable, but reliable peer-to-peer Bluetooth Low Energy mesh/direct messaging across multiple mobile and desktop operating systems without internet is notoriously tricky to implement reliably.
What it would actually take: Built with Flutter, React Native, or Tauri/Rust, integrating existing Nostr client libraries (e.g., nostr-tools, rust-nostr) for relay communication and cryptographic handshakes (secp256k1, ChaCha20-Poly1305). The hard part is the cross-platform BLE multi-peer discovery and direct data transfer layer, which requires handling OS-level Bluetooth power management, background execution limits on iOS/Android, and MTU fragmentation issues.
