It's my understanding that labeling UTXOs are not on chain but shown with wallet software. As wallets become more compatible with each other, these labels should be fairly easy to import from each other. While this makes management easier it got me thinking a bit and made me realize I don't have a clear idea of the boundaries of these labels.
- From a privacy standpoint, can someone see your labels if they had your pubkey to pop into wallet software?
- When combining UTXOs, the label gets destroyed correct? In transaction history in wallet software would that show your previous label still before combining?
- When splitting a UXTO, does your label stay with the remainder?
Basically I was curious to how easy it would be for an interested party to see a person's labeling.
