When I want to transfer ppc from my wallet to another wallet, is it possible to add a “note to the payee”, so that the receiver of the coins can relate the transfer somehow?
In the peercoin-cli client I don’t see an option to do that, hence my question. In the transaction list (‘peercoin-cli listtransactions’) I see that there is a “label” field, which looks like it could serve the purpose, but I don’t know whether it does. It is empty in all my transactions.
The next question then: if it is possible to add note to payee, is it possible to execute a predefined callback when a transaction comes into the wallet? I would need some function that is executed on an incoming transaction, takes the transaction as parameter and does something useful based on it, i.e. notify some web service… programming language doesn’t matter. Is that possible?
