Sometimes, when I click to check, I see a lot of addresses. I have a vague idea that it is for processing the payment(correct me if I am wrong). The question I have is: how are the payment transactions processed? What actually goes on there?
Transaction inputs are used for the payment
Transaction outputs are the addresses which the inputs are sent to. The output can consist of change address (the address that the remaining changes goes to after paying all the addresses included).
