Five questions. Five different proofs.
The model is split on purpose. The five steps are not a chain where proving A proves B, C, D and E. Each answers a different question and rests on different assumptions, which is why each one below says what it proves AND what it does not.
Proof model
The five steps, side by side
Signature
Signed by the company itself
What it proves
Shows the seal can be traced back to an organisation that enrolled with Atestan.
What it does NOT prove
That the request was received, carried out, or legally valid. And it proves the ORGANISATION, not the person at the keyboard.
Who it was for, on the day it was sent
Addressed to your organisation
What it proves
Evidence about who the request was for: that it was meant for the party it names, not a generic item anyone with a copy could reuse.
What it does NOT prove
Receipt, action taken, or legal validity. Being addressed to someone is not the same as reaching them.
Confirmed receipt
Receipt confirmed
What it proves
Evidence that the named party actually received it, a separate question from who it was addressed to.
What it does NOT prove
That anything was done about it. Receiving a payment instruction is not paying.
Closing the record / proving it did not happen
Action not carried out
What it proves
Evidence about whether the request was carried out or closed off.
What it does NOT prove
That the action was the right one, or that anyone was entitled to ask for it. Receiving a contract does not prove it was signed; signing it does not prove it should have been signed.
Public anchor, when the record closes
Locked into a public record no one controls
What it proves
That the whole record can be re-checked later by someone who trusts neither side. That is the point of locking it into a public record no single party controls.
What it does NOT prove
That keeping your own internal record is enough. A record one party controls is not something an outsider can rebuild independently.
Five separate methods, not one chain
These five steps are not links in one single chain. The signature, who it was for, the confirmed receipt, the closed record and the public anchor each work in their own way and rest on their own assumptions. Anyone who tells you “signed, therefore received, therefore not carried out” is selling you a chain that does not exist.
The checker reports evidence, not optimism
An incomplete proof is never rounded up into a confident verdict. What you see is what the evidence proves at the step actually reached, more useful than one green word that hides which part was proved.
Where we are today: In this order, and it stops where the proof stops. Two of the five are BUILT AND TESTED; the other three are specified and not built. And none of them answers a reader today: the service is running, but no organisation is enrolled and no seal has been issued, so the page establishes nothing for anyone yet — it says which is which every time it answers.
