MyZubster: Secure, Private & Decentralized Service Exchange with PGP, Tor, and Geolocation
The Privacy-First Ecosystem
MyZubster is more than a Monero payment gateway. It's a complete ecosystem for private service exchange, designed with security and privacy at every layer.
What Makes MyZubster Different?
- 🔐 PGP-Verified Marketplace – Every order is signed and verified
- 🧅 Tor/Onion Support – Full anonymity with Orbot integration
- 📍 Geolocation – Find service providers near you
- 💬 Encrypted Messaging – End-to-end encrypted chat between users
- 📡 Offline Support – Basic functionality works without internet
- 💰 Monero Payments – Private, borderless transactions
🛡️ Three Layers of Security
1. PGP for Market Integrity
Every order in the marketplace is PGP-signed and verifiable.
How it works:
- Seller creates a service order → signed with their PGP key
- Buyer makes a purchase → order is verified
- Dispute resolution → PGP signatures provide proof of authenticity
javascript
// Example: PGP signature verification
const isValid = await verifySignature(message, signature, publicKey);
if (isValid) {
console.log('✅ Order verified – authentic seller');
}Why this matters: No one can impersonate a seller. Every order is cryptographically linked to the seller's identity.
2. Tor & Orbot Integration
MyZubster connects to the marketplace via Tor for complete anonymity.
How it works:
User opens the app and taps the 🧅 Orbot button
Orbot connects to the Tor network
The app connects to the .onion address of the marketplace
All traffic is anonymized
In the app:
javascript
// DashboardScreen.js – Orbot button
const handleOrbot = async () => {
const result = await connectOrbot();
if (result) {
setOrbotConnected(true);
Alert.alert('✅ Connected to onion marketplace');
}
};
On the VPS (Tor service):
bash
# Tor hidden service configuration
HiddenServiceDir /var/lib/tor/marketplace/
HiddenServicePort 80 127.0.0.1:4000
Result: Your identity is hidden. Your IP is never exposed.
3. End-to-End Encrypted Messaging
All chat messages between users are end-to-end encrypted.
🔑 Public/Private Key Exchange – Each user has a unique key pair
🔒 Messages encrypted before sending – Only the recipient can decrypt
📱 No middleman can read – Not even the server
How it works:
User A sends a message → encrypted with User B's public key
Server stores the encrypted message (cannot read it)
User B decrypts with their private key
Why this matters: Even if the server is compromised, your messages remain private.
📍 Geolocation – Find Services Near You
The app uses geolocation to help you find service providers in your area.
📱 Real-time location – Shows professionals near you
🗺️ Map view – Visualize service providers on a map
🔍 Filter by distance – Find providers within a specific radius
📍 Offline availability – Works without internet connection
Use case: Need a plumber? A web developer? A tutor? Find them near you in seconds.
💬 Encrypted Messaging – Private Communication
Messages between buyers and sellers are end-to-end encrypted.
Features:
🔒 End-to-end encryption – No one can read your messages
📎 File sharing – Attach images, documents, and files
✅ Read receipts – Know when your message was read
📱 Push notifications – Real-time alerts for new messages
📡 Offline Mode
The app works even without internet connection.
📱 Browse cached services – View previously loaded services
📝 Draft orders – Create orders offline, send when online
💬 Cached messages – Read previous conversations
🔄 Auto-sync – Automatically sync when reconnected
