What waiTransport will sign, and how each figure will be assured.
- Group receipts for every track waiTransport will deliver: a content hash per object, a Merkle root per group, and a signature linked to the previous receipt.
- Energy measured on waiTransport's own encode, packaging and relay work, with hardware meters where the hardware has them. Every figure labelled with its acquisition class.
- Energy assurance, figure by figure: each figure published with its measurement report (the meter, its acquisition class and what the figure covered), so a reader can check how it was obtained.
- The stage claims and session claims that sinks sign, kept beside the delivery receipts they name.
- A C2PA manifest for each reconstruction waiTransport will measure, binding its energy figure to that reconstruction.
Open components, each with its WAI label.
- In the standard
Group receipts: a content hash per object, a Merkle root per group, an Ed25519 publisher signature and a link to the previous receipt, chained per publisher key and track.
- In the standard
Typed receipt classes (delivery, energy, lawful-basis, log-inclusion, stage, delivery-gap and session), with an independent verifier and differential tests.
- In the standard
A relay cannot splice, replay or hold back a track's receipts unnoticed.
- In the standard
Energy acquisition classes, signed beside the figure: CalibratedInstrument, OnChipCounter, ModelBased or Estimator.
Notes Unmetered work carries no figure and reads as not metered.
- In the standard
Energy meters: a hardware counter meter, or a calibrated instrument with its calibration reference, and a model meter that only ever yields a modelled figure.
Notes A meter that cannot measure returns no figure; it never falls back to a fabricated one.
- In the standard
Measurement claims report on an energy figure without changing the receipt that seals it, and ratios are derived by every reader, never stated.
- In the standard
A power reader counts only while its rail advances: a rail that stops advancing is refused, and unmetered work is never a figure of zero joules.
- In the standard
C2PA manifest emission that binds an energy figure to the reconstruction it was measured over.
Notes An optional build feature. The manifest validates; signer trust comes from the verifier's trust list.
- In the standard
Stage claims: a sink signs the stage it presented for each unit, the stage delivery reached and each refinement object's fate.
- In the standard
The signed session claim: what a sink presented when, what arrived and what was missed.
Notes Timings, missed deadlines and switches remain the signer's statements, as do the facts of an encrypted envelope that only its payload shows. A sink that received a multi-rendition envelope only as byte ranges cannot yet state its classical length.
- In the standard
A key log at a web origin the signer names, so verifiers confirm receipts and claims offline.
In active development in the standard.
- Building
Receipts served over HTTP, with a receipt index a client follows by hash to an object's group receipt, its stage claim and its chain.
Planned, in the standard and in the service.
- Roadmap· waiTransport
Attested energy measurement on waiTransport's own hops, with a measurement report for every figure.
- Roadmap· WAI
Energy receipts for origins, hops and relays, and steering that reads them.
What this page does not claim.
- Energy figures cover the work measured. They do not cover displays.
- A modelled figure is labelled as modelled and is never presented as measured.
- Fleet and period totals, and energy and carbon reports across an organisation, belong to waiOS: Energy and carbon reporting.
- No energy saving is stated on this site.
