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?
transaction id will give more clarity about the transaction has been sent or not. If the transaction shows as pending or waiting you should wait until the bitcoin transaction. Now number of confirmation has been increased from 2 to 6. However, transaction will be get confirmed faster than now.
There are many bitcoin explorer in the Google results use one among to check the transactions.
