An OP_CODE or Operation Code, is a primitive code or instruction that allows us to program operations within a blockchain like Bitcoin. In fact, thanks to the set of these codes, we can create advanced programming structures or smart contracts that are then read and executed by the nodes of a blockchain network.

Lhe instructions and instructions used in computing for programming computer equipment and virtual machines are known as OP_CODE (Operation Code) o operation codes.

These codes indicate the operations or functions that must be performed and executed by the hardware or software. In the case of hardware, the shape of the OP_CODE will be defined according to the type of operations set architecture (ISA) of the computer. That is, according to the instructions that the device has for t
