is it possible to create a system which one can create a wallet and people can exchange messages to btc addresses?
Let says I own 1YSdmjsodjcioahciafkjf89u and so i write a message going to 3dfadvjvq0rifsmvksdmvlasmdvkj using the client software. so to the end side, one can read the message once he open his wallet.
Do you mean like transaction notes?
If you make it on the Blockchain, it must be take a fee right? And you have to wait for some minutes for the message to be deliveren, just like the transaction confirmations.
That would mean you will have to send an amount to the btc address to simply send a message to that recipient btc address as well.
I'm not sure if it really exist, let say a btc address exists which has tons of btc into it but the funds were gotten by fraud and what i could do is send a message to it.
but this will not fetch any purpose because if he has done fraud then he wont even reply your message, ya but atleast if anyone genuinely sent it by wrongly then he can request the person to sent it back. but message sending process is very good. and i think in every wallet if you are sending coins their is a message box below where we can send the message to the coins sender address.
