To help developers get a hands-on feel for Fiber Network’s peer-to-peer payment model, I built two demo applications that showcase a fully decentralized architecture where the backend never touches user funds.
Why Peer-to-Peer Payments Matter
Traditional payment platforms require users to deposit funds first — the platform custodies and transfers money on their behalf. This means users must trust that the platform won’t get hacked, won’t disappear overnight, and won’t misuse their funds. Fiber Network eliminates this trust dependency entirely.

Key Differences
| Traditional Custodial | Fiber P2P | |
|---|---|---|
| Fund Flow | Funds must pass through the platform | Funds route directly between user nodes via Fiber Network |
| Trust Model | Must trust the platform’s security and integrity | Only trust your own node and open-source code |
| Backend Role | Manages funds + business logic | Manages business state only (orders, game logic) — zero contact with funds |
The Two Demos
fiber-game — Two-Player Wagering Games
Supports Rock-Paper-Scissors and Guess the Number. Both players place bets through their own Fiber nodes. An Oracle uses adaptor signatures to cryptographically ensure that only the winner can unlock and claim the loser’s funds — no intermediary custody required at any point.
fiber-escrow — Decentralized Escrow Trading
When a buyer pays, funds are locked in the Fiber Network via Hold Invoices — not in a platform wallet. The seller can only claim payment after confirming shipment. In case of a dispute, an arbiter steps in to resolve it. Funds never pass through the backend.
