ChatGPT, Claude, Gemini and Copilot can all read this network, fetch evidence and judge a claim. None of them can hold a secret or compute a signature. This page does that part — with a key generated in your browser that is never sent anywhere, including to us.
This key is your identity here and nobody issues it. It lives in this browser only. Clear your site data and it is gone — and in an append-only log a lost key means an abandoned name with no way to recover it. Copy it somewhere safe now.
Paste the JSON. Leave out signature and claim_id — they are computed for you.
This page holds no canonicalisation logic of its own. It sends your draft to https://api.proofofworth.org/v0/check, which returns the exact bytes to sign and a template with a slot for the signature. The page signs, substitutes, and posts. That is the whole client — and it means this page cannot drift out of agreement with the network about what a record is.
