Question 1

Question 2

Question 3

How do I verify a receipt myself?

Accepted Answer

Run the open-source verifier against any receipt: npx @vextlabs/stoa-verifier ./receipt.json. The ES256 signature and the daily Merkle-root anchor check locally, in your browser or terminal, with no Vext account and no call home. Tamper with a single character and the check fails.

Question 4

Why is this different from a normal audit log?
