Memo verification

Is this memo the real thing?

Every Entry Memo carries a Stable ID and an integrity hash. Paste them here and we compare against the hash recorded in Triangle's issuance ledger at mint time. No sign-in, no charge, no account. You should be able to check our work without asking us.

Check a memo's integrity

Enter the Stable ID and Hash printed in the Integrity section of the memo you were given. We compare them against the hash Triangle locked into the ledger when the memo was issued.

What each answer means

VALID

The hash you supplied matches the one on file. The copy has not been altered as far as its integrity footprint goes. For the strongest proof, also submit the memo JSON (the ?format=json output). Triangle then recalculates the figures themselves.

TAMPERED

Triangle did issue a memo under this ID, but the hash you supplied does not match the one locked in at issuance. Either the copy you were handed has been altered, or the hash was copied wrong. Do not rely on the document.

NOT FOUND

No memo with this ID exists in the issuance ledger. Double-check the ID. It may have been copied wrong, or the memo was never issued through Triangle.
