How does it work?
In a P2P BTA system a "Bus" exchange node would cycle through and collect orders from P2P "home-server" nodes mentioned in the above posts. "Home-server" nodes house user accounts and wallets in a P2P network.
1. The Bus exchange server node would collect orders from home-server nodes 1 through 25 (for example).
2. Matching orders (if any) are fulfilled in a mini exchange. Receipts are generated. All unfulfilled orders and receipts are then stored for pickup by an "Train" exchange node.
3. On a predetermined cycle the higher Train exchange node would pick up all of the unfulfilled orders and receipts from all four (for example) of the Bus exchange nodes in the P2P network. All matching orders are fulfilled in a medium sized exchange and more receipts are generated. Again, All unfulfilled orders and collected receipts are then stored for pickup by an "Airplane" exchange node.
4. Finally, on a predetermined cycle the higher Airplane exchange node would pick up all of the unfulfilled orders and receipts from all four (for example) of the Train exchange nodes in the P2P network. The Airplane exchange is the highest exchange on our example P2P network. All orders would attempt to be fulfilled here. Collected receipts are used to generate reports and to display fulfilled orders.
In our example P2P network, if no orders were fulfilled by the Bus or Train exchange nodes then the Airplane exchange node would have picked up 400 orders.
