Verification
Check a proof
Paste a Cachet proof link or open the file. The checking happens in this browser, against the NEAR chain. You need no wallet and no account, and nothing is uploaded.
What gets checked
- The invoice details are hashed again and compared with the seal on chain.
- The payment is read from the contract: amount, token and settlement time.
- Each payment's signature is checked against the key that owns it, over the statement naming you.
- The chain is read through 3 endpoints run by different operators, and a payment counts as confirmed only when 2 of them agree.
The third check is why a client who paid one of these invoices cannot present it as their own income. The fourth is why no one endpoint can tell you a payment happened when it did not.
