Verify a Proof — Verafile Sentinel

Verify a sealed package

Upload the original file(s) and the sentinel.proof.json to confirm the package is unaltered and anchored on Base Mainnet. No account required.

Step 1 — Upload the original file(s)

Choose files to verify

Step 2 — Upload sentinel.proof.json

Choose sentinel.proof.json

Verification runs the same procedure printed on every receipt: each file is re-hashed with SHA-256, the salted root preimage is reconstructed and hashed, and the result is confirmed against the transaction on Base Mainnet. This can also be done entirely by hand — no Verafile account or software is required.
