Open-source. No phone number, no email, no metadata harvesting. Engineered to keep working on hostile mobile networks where other messengers are restricted.
PHANTOM is not another chat app with an encryption sticker. Every design decision assumes a hostile network and an adversary with state-level resources.
A custom Double Ratchet implementation over libsodium, with ED25519 identity keys generated on your device. The relay never sees plaintext.
Multiple transport paths reach the network, including traffic that blends in with ordinary HTTPS. When one route is blocked, another takes over.
No phone number, no email, no real name. Sealed-sender routing means the relay cannot build a graph of who talks to whom.
Licensed AGPL-3.0. Every line is auditable — no closed components, no hidden telemetry, no trust-us black boxes.
Each mode picks a different chain of transports to reach the network — trading latency for resistance. Ghost never silently downgrades: if it can't go through Tor, it fails visibly rather than exposing you.
Direct-first chain. Lowest latency for everyday use on open networks.
Reality-first chain. Hides your source IP from the relay behind cover traffic.
Tor-only chain. Never silently downgrades — fails visibly if Tor can't bootstrap.
Encrypted WebSocket over TLS for normal conditions.
Traffic indistinguishable from ordinary TLS. Validated through Russia's TSPU in production.
Text-only emergency fallback for hostile networks. Does not carry calls.
Short-poll delivery when WebSocket frames are silently dropped.
Peer-to-peer transport without infrastructure. Planned — not yet built.
PHANTOM is in active development (Alpha 2), Android for now. Text messaging is reliable across the multi-transport stack, and the censorship-circumvention transport has been validated against TSPU in production. Voice notes work; voice calls are experimental. Group chats are partial. iOS, channels, and offline mesh are in the next stage of development. We ship a release only when the claim has been tested on real devices.
