Take nobody’s word for it.
Not even ours.
On paid plans, every figure in a Vugo® Measure report is quoted from a signed receipt. A receipt is a small document that says what was counted, over what window, from which sources, with what grade, and it carries a cryptographic signature so anyone can confirm Vugo issued it and nothing in it has changed since.
Re-signed as data arrives. A correction is a new receipt that says why; the old one still verifies.
Everything behind the number.
The window
Start and end, the market timezone, the flight dates, and the cutoff rule that produced them.
Supported hours
The total, split by how each hour was established: an exact scheduled trip, or a scheduled route without a trip id.
Off plan, unknown, excluded
Hours on another route, hours the schedule couldn’t classify, and time excluded, with the reason for each vehicle.
Breakdowns
The same figures per market-local day and per assigned route. They always add back up to the totals.
Withheld
Any period or field held back for rights reasons, named as such. Withheld is never shown as zero.
Grade and lineage
The evidence grade, the measured inputs behind it, feed availability, and a digest of the observations counted.
No account. No trust required.
- Signed
- Each receipt is canonicalized and signed with an Ed25519 key. Change one character and the signature fails.
- Published keys
- Vugo publishes its verification keys, and keeps them published after they’re retired, so a receipt from last year still checks out next year.
- Anyone
- A buyer, an operator, an auditor, or a client of a client can verify a receipt without a Vugo account, using the public verifier, the API, or a command-line tool.
Check a receipt now.
Paste a complete receipt into the public verifier and get a plain answer: valid or not, and which published key signed it. No account, nothing stored.
Nothing is edited. Things are re-signed.
Receipts are append-only. As data arrives during a flight, a new receipt is issued and the previous one stays on record. If something has to be corrected, the correction is a new receipt that says why, and the original still verifies as what Vugo said at the time.
That is the point: the number you quoted to a client in week two is still provable in week ten, even if the final total moved.
