The financial system is a network of closed networks.

Sovereigns, banks, dealers, custodians, members — each runs its own ledger and hands assets across at the seams.

ƒxyz is the graph.

One substrate covering the physical, electronic, and digital realms — queried, not assembled.

Functions run on the substrate.

Routing, matching, scoring, governance — every function is a query against the same graph.

Members open closed circles.

Introductions cross the seams. Cryptography keeps the closure intact while the network widens.

Enter by introduction.
