Vext Labs and Theron: frequently asked questions

Question 1

What is Theron Receipts?

Accepted Answer

Theron Receipts seals every action an AI takes into a signed record anyone can verify yourself, offline, against an open-source verifier, with no Vext account. Drop one line into any AI or agent app and every action it takes emits a receipt your customers and auditors can check.

Question 2

What is Theron?

Accepted Answer

Theron is the AI by Vext Labs that shows its work. Every action it takes is sealed into a receipt you can check yourself, offline, against our open verifier, with no account.

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?

Every audit log on the market is written by the company you are auditing, so you have to trust them. Theron Receipts flips it: the proof travels with the receipt and you run the math yourself, offline, against an open verifier. No trust required.

The verifier is free and always will be.
