As mentioned previously, ScriptPubKeys are scripts that embody the locking conditions of bitcoins in a Bitcoin transaction. They are a crucial element of a Bitcoin transaction that specifies the requirements that must be met before an unspent transaction output (UTXO) is used. The ScriptPubKey, combined with the Amount, creates an output of a Bitcoin transaction. Like every other script, ScriptPubKeys are made up of operators and data. During the encoding of a transaction, both data and the operands are represented in hexadecimal format. You can find the hex representation for all operands used in Bitcoin Scripts here.
