Kiyeovo is a decentralized, end-to-end encrypted messenger. It requires no accounts, no email, no central servers. Peers find each other and talk directly over libp2p. kad-DHT stores messages for offline peers and handles finding other users by their username/peerID. After almost a year of solo development, this is the first release.More details are in the repository README, but in short, here are the features:- realtime end-to-end encrypted messages- Direct & group video and audio calls with screen sharing options- messages securely persisted when the other side is not online- group chats, group calls- fast mode is for normal day-to-day use: lower latency, relays, audio/video calling- anonymous mode is for Tor-routed messaging. Better anonymity, but slower and no call support- encrypted file transfers- trusted profile import/export- identity backup- no central account or message server -> use trusted bootstrap/relay servers or self-hostThis is a single developer effort. It has not had a formal security audit so please don't rely on it where your safety depends on it. Feedback and bug reports are very welcome.P.S. The repo contains addresses of infrastructure nodes that I published, so for a quick start and no friction, you're free to use those. Try it out!

Could you build this?
No Building a serverless, peer-to-peer, end-to-end encrypted messaging system with offline message delivery requires deep distributed systems, cryptography, and network engineering expertise.
What it would actually take: The architecture relies on libp2p for peer routing, transport multiplexing, and NAT traversal (STUN/TURN/AutoNAT), combined with a Kademlia Distributed Hash Table (DHT) for peer discovery and store-and-forward offline messaging. The hardest challenges are reliable message replication across ephemeral DHT nodes without spam exhaustion, alongside a secure cryptographic protocol like the Double Ratchet. This requires seasoned systems and security engineers experienced in distributed peer-to-peer protocols.
