I was doing a test today...for no real particular reason. I have a CLN and LDK node running. First I made a bolt 12 offer on my CLN. Using a coinos.io account, i made a 5 sat zap to it. Before I executed the send, coinos show the node ID / alias of who you are sending to. This did not surprise me, I've seen this before and it showed the node ID info of my CLN.
I then sent a 5 sat zap from my coinos.io account to an offer I made on my albyhub LDK node. Before the send executed, the alias ID was not my LDK node's ID. I sent the sats, they did indeed go to my LDK node. It's a 10-digit string of numbers and letters that didn't look particularly recognizable as say a short channel node ID or something.
Does anyone know why that would be? Are LDK offers blinded, but CLN offers are not ? Thanks for any insight.
