How the meter works

Aquadrio is a four-stage pipeline that turns a running compute job into a signed, per-job record of its embedded carbon and water, and mints a credit on the rare window that clears both gates.

01
Sense

An Oracle reads the live grid mix and facility state and computes the window's carbon intensity and water figures. The grid feed is delayed, never real-time, and labeled as such.

02
Gate

A Matchmaker applies both gates: the clean-energy gate (≤100 gCO₂/kWh) and the water gate (facility WUE ≤2.0 L/kWh). When a window fails either, it holds. Holding through dirty and peak windows is the restraint the instrument certifies, so the everyday state is a hold, not a mint.

03
Stamp

A Provenance Stamper measures the job, aggregates every execution window into a composite record, and seals it with a sha256 hash over a fixed canonical form. An optional signature is additive to the hash.

04
Mint

On the rare window that clears both gates, one Renewable Compute Credit is minted per certified GPU-hour, referencing the record. There is no volume counter and no celebration.

The unit: 1 RCC

Definition

The RCC is the umpire's call made durable: one credit per GPU-hour that ran certified clean.

The credit is a direct analog to a renewable-energy certificate: a wind farm produces clean energy and a certificate at the same time; a facility produces clean, water-passing compute and a credit at the same time. The GPU-hour is the headline unit, hardware type and form factor are mandatory attributes, and no cross-hardware equivalence is asserted. Water never changes the count; it only determines whether a clean window is eligible to mint.

The certificate, as an object

Every field on the credit traces to a source, and the whole record recomputes from its own inputs. This is the anatomy; the downloadable sample and the offline verifier are on the verify page.

The uncoolable upstream figure: the water consumed generating this job's electricity, recomputed from the certificate's own per-window generation mix using the Standard's published factors. It is derived, off-hash, and shown with the recompute recipe on the verification page. Water consumed, never withdrawn.

Specified and severable, not built yet.

What is real, what is modeled, what is deferred

The honesty legend is first-class, not fine print. Every surface on this site and in the app carries these tags, and they never blur.

REAL

Measured or computed from live data now.

MODELED

Derived from published figures, labeled as modeled.

DEFERRED

Specified and severable, not built yet.

REAL the live delayed grid carbon signal; the indirect water computed from grid factors against the live mix; the measured energy basis; the gate, restraint, and mint logic; the provenance and sha256 hash; the ledger; and the offline-verifiable bundle.

MODELED direct and cooling water via published water usage effectiveness benchmarks; facility profiles; and the simulated demo workloads the public meter runs, each labeled.

DEFERRED tradeability and any exchange; real facility water metering, which arrives with a pilot; the retired-GC reference (the granular_cert_ref field is null on every certificate today); and signing-key custody.

The parked endgame

The credit is designed so that it could, later, become a tradeable instrument with a market on top. That is the endgame, and it is deliberately severable and parked. It is specified and deferred, not in progress. There is no price, no counter, no forward-value framing anywhere on this site, because none of that is what the instrument is for today.

The standing line

The RCC is not for sale.

Aquadrio mints credits to demonstrate the rarity and to record the embedded cost. It does not offer them to anyone. Any future offering would follow legal review; until then the answer is no.
