Solutions
Use cases
Evidence for the questions your systems will be asked.
What did the agent do, and in what order? Which notice did a person get before talking to an AI? Start from the need. Each page explains where the question comes from, how Trustvice 360 records the answer, and exactly what that record can and cannot show.
Every solution ends in the same kind of artefact: a signed, tamper-evident record that someone other than you can check against Trustvice's published keys. What changes is the fact being recorded.
The same receipt answers different people. These groupings are a starting point, not a rule: most needs touch more than one team.
Engineering
You build the agent, the pipeline or the integration, and you will be the one asked to show what it did. You want evidence that is produced by the code path itself, with no extra system to run.
You need records that hold up when someone else checks them: a regulator, an auditor, a customer’s counsel. You also need to know precisely where that evidence stops.
Use cases
Where the record matters most.
Three categories where Trustvice's artifact is the difference between an explainable AI deployment and one that breaks down under regulatory or customer scrutiny.
Whatever the need, a signed receipt has the same four properties. They are narrow on purpose.
01
Integrity
Change one character of any field and the Ed25519 signature stops verifying.
02
Time
The receipt existed no later than its issuedAt. It is an upper bound on when the fact was recorded, never a lower one.
03
Origin
It was signed by a Trustvice key published at https://trustvice.com/.well-known/receipt-keys.json, so a verifier needs no relationship with you or with us.
04
Content binding
Receipts carry hashes. Anyone holding the original bytes can recompute the hash and match it; the hash does not reveal the content.
What no receipt does
It does not make a reported fact true. Where you supply the facts, the signature makes your statement tamper-evident, not correct.
It does not show that nothing is missing. A missing receipt is invisible unless something else says it should exist.
It does not make anyone compliant with a law, and it is not a notarisation or a qualified timestamp.
