A Bitcoin script using OP codes is a script compiled from a custom set of operations that are used to verify the validity of a Bitcoin transaction. For example, OP codes can be used to check that a specific account holds the funds needed to complete a transaction, or to enforce rules related to the usage of private keys. Scripts can also be used to execute more complex operations, such as multi-signature requirements, time locks, and escrow. Popular OP codes include OP_CHECKSIG, OP_EQUAL, and OP_VERIFY.
