ƒxyz — the graph
Every economy is a network.
Nobody had drawn them as one.
A network begins with one edge.
Two counterparties sign an agreement. Repeat a million times. You get a network.
Money takes three forms.
Paper in bags. Electrons in wires. Digits in blocks. Three rails that rarely meet.
Counterparties clear each other.
Every bilateral agreement is an edge. Add enough counterparties and the matching network forms on its own.
Ask for a route.
Name the currency. Name the counterparty. Name the corridor. The network returns the route.
Observe a vertex.
Every node opens into another graph. A bank is a correspondent chain. A sovereign is a treaty net.
The network closes.
Every currency. Every counterparty. One network.
The network is live.
Value moves along the route. Enter by nomination.
