How Does a Transaction Using a Stealth Address Differ from a Bitcoin Transaction?

A Bitcoin transaction is pseudonymous; the sender and receiver addresses are public and reusable, linking transactions to an identity over time. A stealth address transaction is more private; the sender generates a unique, one-time public address for the recipient, making it impossible to link the transaction to the recipient's main address or to link multiple transactions from the same recipient.

The transaction amounts may also be obscured.
