Core Concepts

The Watt, Carbon-aware routing

The scheduler treats grid carbon intensity as a first-class routing input, sending each job to the cleanest node that meets your latency budget.

Carbon-aware routing

Grid carbon intensity varies by hour and location by roughly an order of magnitude, the same job run elsewhere or later can be far cleaner. Given a job and its latency budget, the Watt picks a route by strategy:

  • greenest, lowest gCO₂/kWh at that hour
  • fastest, lowest latency
  • cheapest, lowest cost per token

Routing runs with circuit breakers and failover, so a bad node never strands a request.

Metering & CarbonScore

Every completed job is metered, energy drawn (kWh) and estimated gCO₂, and stamped with a CarbonScore that flows into its Green Compute Certificate. Accounting is hourly and serialized so emissions can never be double-counted.

Grid-timed scheduling

Non-urgent batch work can be deferred to the greenest hours of the day automatically, cutting both cost and carbon without you managing a schedule.

Renewable verification

Nodes attest their energy source (solar / wind / hydro) through the solar connector, which reports live source, grid intensity, and mints the hourly Energy Attribute Certificates behind each job. A cleaner mix earns a higher ranking and reward multiplier.

Source priority runs solar → stored solar (battery) → grid, with battery state-of-charge factored in, real hardware or simulator mode.
