## Opcodes

Opcodes are the fundamental, low-level instructions that a virtual machine executes to perform tasks on a blockchain. Each opcode corresponds to a specific operation, such as adding two numbers, storing data in memory, or interacting with another contract.

Because each opcode has a predefined gas cost based on its computational intensity, the sum of these costs determines the total price of a smart contract function. Developers who understand opcode costs can write highly optimized code that performs complex financial calculations while minimizing expenses.

In the realm of financial derivatives, efficient opcode usage is the difference between a profitable protocol and one that is too expensive to use. Analyzing opcodes is a key part of technical audits and performance tuning for high-performance decentralized finance applications.

It provides deep insight into how code interacts with the underlying blockchain infrastructure.
