I am new to hyperledger and online payment.
One scenario I have in mind is: if A is an online shop, B is a consumer. B orders an item from A's shop and pays with Bitcoin/hyperledger. A ships the item to B once the payment is received.
With hyperledger, the process goes:
B sends A the payment via blockchain;
A is able to query how much money A owns;
But the question is:
How does A know if the transaction was from B?
How does A know how much money was sent by B?
How does A know if the transaction from B is for the specific ordered item?
Thanks,
