10 minutes is a rough guideline on how long it takes the network to confirm a payment, and verify that a transaction is not a double-spend or otherwise invalid.

10 minutes is a rough guideline on how long it takes the network to confirm a payment, and verify that a transaction is not a double-spend or otherwise invalid.
