  • I've read the intro to grin but I'm still missing something. When a transaction is posted on the blockchain, how does the payee learn r (i.e. the blinding factor)? Is it sent through an encrypted channel directly? In that case, do the sender-receiver need to be online at the same time? And if encrypted, under which key does the sender encrypt r?
