The five standard types of transaction scripts are pay-to-public-key hash (P2PKH), public-key, multi-signature (limited to 15 keys), pay-to-script hash (P2SH), and data output (OP_RETURN), which are described in more detail in the following sections.

These contain a locking script that encumbers the output with a public key hash, more commonly known as a bitcoin address. Transactions that pay a bitcoin address contain P2PKH scripts. An output locked by a P2PKH script can be unlocked (spent) by presenting a public key and a digital signature created by the corresponding private key.

For example, let's look at Alice's payment to Bob's Cafe again. Alice made a payment of 0.015 bitcoin to the cafe's bitcoin address. That transaction output would have a locking script of the form:
