O Coin needs two kinds of truth in code: (1) local water price in each fiat lane where we can observe it, and (2) a connected graph of cross-country references so every currency lane stays defined and checkable even when a direct measurement round fails. We do that by treating the network as a measurement scheduler: the chain picks who gets invited not only to fight spam, but to fill geographic holes, close FX triangles…
