ECU Contract

ECU = 1 kWh × 1 GPU-second. Energy × compute.

Gradient-based capacity becomes purchasable. Price locked on allocation.

Spend Path

ECU Spend Path

quote → allocate → receipt → settlement

Settlement Path

gradient execution → ECU emission → currency settlement

ECU SETTLEMENT SURFACE

  • Gradient-based capacity becomes budgetable
  • Capacity becomes comparable across actors
  • Capacity becomes contractable at scale
  • Settlement produces recurring extraction
