That is two questions, however I will try to reply each:
The “receiver” of a bitcoin transaction is de facto simply an deal with that in your case occurs to be a peson and the place that deal with is related to a Pockets, e.g. a software program app, put in on a SmartPhone.
The pockets app could have an space inside it permitting customers to view transactions. Relying on the pockets, it’s going to both show as cash despatched and acquired, or present a hyperlink to an exterior service corresponding to https://blockchain.information the place information in regards to the transaction may be seen. Utilizing the latter, the receiver (truly, anybody) can see that the deal with you used to ship cash to, has been used as an “Output” in a transaction, and the deal with used to ship the cash (e.g. your personal pockets deal with) has been used as an “Enter” to that transaction.
In abstract: If each the sender and receiver deal with are displayed on blockchain.information, and have at the least 6 “Confirmations”, you possibly can just about safely assume that the cash have been efficiently despatched and acquired.
As for methods to ship cash to a different pockets, you’d observe the identical precept:
1). Receive deal with from the particular person you want to pay
2). Utilizing any pockets, punch in that deal with
3). Choose the quantity of coin to ship to that deal with
4). Hit “ship” or “pay” or no matter.
I hope that helps.
