Decentralized Messenger

Zentalk

Trust Math, Not Servers, Powered by Human. Every message is encrypted on your device — nodes relay what they cannot read. No phone number. No central server. Open source.

01 · Security Model

Trust Math,Not Servers

Your privacy is enforced by cryptography, not promises. How Zentalk encrypts, routes, and hides your traffic — and what the network can never see.

Encryption

Signal Protocol

Every message, call, and file is encrypted on your device before it touches the network. Signal Protocol generates a unique key for every single message. Keys are deleted after use — compromising one message cannot reveal any other.

Architecture

Server-Blind

Nodes store and relay your data but cannot decrypt it. Messages, contacts, profiles, presence — everything encrypted. No master key, no backdoor.

Privacy

Multi Routing

Every message passes through three independent relay hops. The first knows the sender, the last knows the recipient. No single relay ever knows both sides.

Identity

Zero-Knowledge

Prove you belong to the network without revealing who you are. Spammers are identified automatically while legitimate users stay anonymous.

Stealth

Invisible Patterns

Decoy traffic when idle. Messages padded to the same size. Unique network address per message. Status delayed and randomized. Nobody can tell when you communicate.

Offline

6km Range

With a Zentanode nearby, Zentalk works without internet — up to 6km range. Local wireless mesh for direct device-to-device communication. Always encrypted.

Web3

No Phone Number

Sign in with MetaMask, WalletConnect, or any Web3 wallet. No phone, no email, no password. Your wallet is your identity.

Quantum-Safe

Post-Quantum

Hybrid encryption combines current and quantum-resistant cryptography. If one layer breaks, the other still protects. Both must fail for any compromise.

02 · Full-Featured Messenger

Everything You Need. All Encrypted.

Messaging, voice and video calls, groups and channels, stories and media, polls and location — plus the enterprise and compliance features.

Chat

Messaging

Text, voice messages, reactions, replies, forwarding, editing, and disappearing messages. Pin favorites, star important ones. The server cannot read any of it.

Calls

Voice & Video

Peer-to-peer calls with no server in between. Group calls up to 6 participants, each connected directly. Screen sharing in any call. All signaling encrypted.

Groups

Groups & Channels

Encrypted group chats with roles and permissions. Broadcast channels one-to-many. Group membership hidden from relays. Key rotation on every member removal.

Media

Stories & Media

Encrypted 24-hour stories with viewer control. Images, videos, GIFs, stickers — all encrypted. GIFs delivered through the mesh so recipients never contact external servers.

Features

Polls & Location

Encrypted polls where the server cannot see questions or votes. Location sharing with OpenStreetMap. Maps only load when you choose — no data leaks to third parties.

Enterprise

Compliance

GDPR, HIPAA, and SOC 3 compliant. Multi-factor authentication with hardware security keys. Manage sessions across devices. Safety number verification for encryption integrity.
