 ## Event
 
 - An **event** is the user-facing representation of the effects of executing a transaction.
-- A transaction may be designed to emit any number of events as a list. For example, a peer-to-peer payment transaction emits a `SentPaymentEvent` for the sender account and a `ReceivedPaymentEvent` for the recipient account.
-- In the Aptos protocol, events provide evidence that the successful execution of a transaction resulted in a specific effect. The `ReceivedPaymentEvent` (in the above example) allows the recipient to confirm that a payment was received into their account.
