Verify a Touchstone disclosure

Paste a disclosure (or load one by its /d/<token> link) and verify it in your own browser — the checks run client-side via Web Crypto, nothing is sent back to us.

Want full independence?

This page loads JS from us, so for a fully independent check run the standalone verifier (no Touchstone code, no network) — or just read verifier.js, it's small:

curl -s https://touchstone.cv/d/<token> | php verifier/verify.php

Either way it proves integrity (nothing edited), attribution (signed by the subject key) and ordering (chain + Merkle under an external anchor). It does not prove completeness — omission is possible below the evidence/inline tiers. For Bitcoin (OTS) proofs, verify the receipt with the canonical ots tool.
