POST Token Whitepaper
Use Cases & User Journeys
Detailed user journeys for POST Token's three business lines: postal operations, money transfers, and merchant payments. Every journey demonstrates how the POST Gateway model creates seamless user experiences.
The User Experience Principle
What the User Sees:
- "Pay $65" → "Package shipped"
- "Send $500" → "Money received"
- "Pay merchant" → "Payment complete"
What Happens Behind the Scenes:
Fiat → POST → PSDR → Operation → Mining rewards → Settlement
The user never sees tokens, wallets, or blockchain complexity.
