Could you build this?
Partial The chat UI is standard, but building a robust peer-to-peer encrypted messenger without a trusted server requires complex distributed networking, NAT traversal, and decentralized metadata management.
What it would actually take: The system requires libp2p or WebRTC, a distributed hash table (Kademlia DHT) for peer discovery, STUN/TURN/ICE coordination, and an asynchronous cryptographic protocol (such as Double Ratchet / Signal Protocol adapted for offline P2P store-and-forward or gossip networks). Solving offline messaging and NAT hole-punching across mobile/desktop without centralized infrastructure demands specialized distributed systems and applied cryptography expertise.
