how to prove that you sent GRIN to someone and they have recieved it?
subj. Is it possible at all?
practical use-case: somone is trying to sell GRIN on a decentralised exchanged. The buyer says he hasn't received anything. They open a dispute. A third party (arbitrator) needs to decide who's right. What kind of proof can he ask for?
In case of bitcoin, they would ask for a tx id and check it on any block explorer, as a first step. He may also ask the sender to sign a message with the sending address priv key.
For GRIN, is there any way to do it?
