What to check

Each claim, word for word, and where you see it.

Tari's partWhat we claimWhere you see it
Stealth paymentsThe chain shows a payment with a hidden amount and a hidden owner.
The fee is public.
What the chain sees, on the pay page after you pay
A split keyWe keep half of the key and give it to you once the chain shows your payment.
The other half is in the link, which we never see.
Neither half opens it alone.
The pay page
A key inside a paymentSend by Tari: the key rides inside a payment to their address.
Only they can open it.
Share, One Tari address
View keysA view key can't spend, but it can read everything sent to this address, including files.
Give it only to someone allowed to see those.
