SOVP Protocol Active

Messaging's
Freest and Most Secure
Form

Pulse is a fully anonymous, end-to-end encrypted P2P messaging platform powered by SOVP (Sovereign Open Vault Protocol) — P2P communication. No phone, no email, no central server. Just you, cryptography, and freedom.

ARCHITECTURE

The Anatomy of Privacy

Pulse's system architecture builds privacy as a foundational principle, not as a feature.

Ghost Mode — Absolute Anonymity

No phone number. No email. Just a username and a cryptographic Vault ID (VID) generated in your browser. Your identity lives entirely on your hardware, never sent to any server.

VID: x25519_pubkey_hash

Military-Grade E2E

X25519, Ed25519 & ChaCha20-Poly1305 (TweetNaCl).

cipher.suite

Blind Relay Server

Server can never read your messages. Only forwards encrypted packets.

zero-knowledge

Local-First (IndexedDB)

Database lives on your device. Offline messages queue in Redis, sync to device, then permanently deleted from server.

vault.persist(local)

Multi-Device Sync

QR code to link new devices. Fan-out routing delivers messages to all your devices instantly.

device_tags.fanout()

PWA & Push Notifications

Web Push notifications even offline via Service Workers. Native app experience.

service_worker

Massive Scalability

Fastify + Redis Cluster architecture handles 1M+ concurrent active users via WebSocket with zero latency. Infrastructure optimized for low-latency.

TECHNICAL ARCHITECTURE

How the System Works

Anatomy of data flow: every layer from IndexedDB to Relay, from TweetNaCl to P2P encryption is transparent.

Data Is Never Stored

Pulse's core philosophy: the server is just a relay. Your messages live encrypted on your device. If you're offline, they wait in a high-speed in-memory queue (Redis), and the moment you connect, they sync to your device and are permanently deleted from the server.

Blind relay that only forwards encrypted packets

On-device encrypted database (Local-first)
TweetNaCl
Industry-standard cryptography with NaCl library
WebSocket + Redis Pub/Sub
Low-latency channels for instant message delivery
