How to tell it was really us that signed your receipt

Imagine a friend forwards you a receipt from your assistant and says "this is what it did for me six months ago." You want to know it is real. Here is how you can check without trusting our website.

Receipts carry a stamp. The stamp is registered in public.

Every receipt your assistant produces carries a stamp. The stamp is made with something only we hold. To check the stamp, you need the matching public counterpart.

The convenient place to find the counterpart is our website. Click a button, the stamp checks out. That works, but it asks you to trust that our website is telling the truth about which stamp is ours.

The durable place is a public record. We own a public name (operatoruplift) on the same chain we use for the rest of the trust stack. It works like an internet domain, but registered on a chain anyone can read instead of in a private company's database. The name points to one address, and that address matches the stamp we sign with.

Why this helps you

Three reasons, simplest first.

You can verify a receipt without our website. Open a public explorer for the chain. Look up the name. Read the address it points to. That address matches the stamp on the receipt. If somebody tried to fake a receipt with a different stamp, the lookup gives them away.

You can verify a receipt years from now. Websites change. Companies pivot. Public records stay. If you keep a receipt on disk and check it in 2030, the public record still tells you which stamp our name was registered to at the time.

You can tell when the stamp has changed. Companies do rotate stamps, for security or after staff changes. When we do, we update the public record. Anyone watching can see the change. It is never silent.

What this looks like on your security page

You do not have to think about any of this to use the product. Open the security page, you see your receipts. Under the header there is a small "Signed by operatoruplift" line with a link. Click it and the public record opens. If you are not curious, the assistant works the same way it always did. The option to check is always one click away.

Why a public record at all

Two reasons we keep coming back to. First, no single company owns the public record we use, so nobody can rewrite it after the fact. Second, the receipt itself, the record of who signs them, and the backup copy of the bytes all sit in different places, owned by different people. To fake your assistant doing something it did not do, somebody would have to break all three. We made that hard on purpose.

You did not sign up to learn about cryptography. You signed up for an assistant that does the parts of your day you would rather not do. The public record is there so the assistant feels safe to trust when you are not watching.
