Nodal Exchange said on 3 Sept it'll list GPU rental futures this year, settling against "Compute Desk's daily, blended GPU price indexes." That's three exchanges now, after CME and ICE, racing to price an hour of Hopper.
Good. But read the small print: the futures settle on an index one private firm computes from quotes nobody outside it can re-run.
A futures curve is only as honest as its spot. $ FLOP is meant to be that spot, a token that redeems for compute at a price miners bid against each other and validators re-execute. Price the hour first. Then hedge it.
