If the amount is different then it’s easy. For the same amount? Public key of the sender? If so, shall I trust my local copy of the blockchain? (I know the “balance” can be faked albeit nobody can steal or send bitcoins in your behalf)
What about big merchants which process large amount of transactions?
Of course I’m not asking how to find out the identity of the senders
