Hey guys,
I know there is no "from" address when we send bitcoins. However, is there any way to prove when B receives btc, it was sent from a particular party? If A and C both claim they sent btc to B with the same amount and B only receives one payment, how do we identify the sender?
Its actully simple thatn you think.
Ask a and c to give their transaction id.
That transaction id have a success full destination address of yours is the actual one who pays.
Also if anyone of them cannot send transaction id.
Surely he/she did not paid.
